General information 8

General information

Paper and label industry

The paper and label industry includes manufacturers, converters, and distributors.
Manufacturers produce the base stock. If the base is for labels, then manufacturers may ship it on large rolls or in
a cutsheet form.
Converters take the base stock and convert it into cutsheet products. Converters may work from rolls with or
without the adhesive applied. They may also take a base stock and convert it to meet their customers' specifications.
The conversion process includes, but is not limited to, cutting the stock to size, perforating the stock, die‑cutting, and applying inks and topcoats. Converters work with their customers to convert the base material into a cut‑sheet product designed for use in laser printers.
Distributors are generally the direct link to the customer.
As needs and prices change, distributors may work with different converters and converters may work with different manufacturers. Most businesses follow accepted industry conventions, but specifications, standards, formulations, and processes may vary with time or with different companies.
As a result, labels or paper that worked well in the past may suddenly create printing problems because of a change in material or process.
Some large businesses perform all three functions, from manufacturing to distribution. These companies may offer greater expertise and product consistency than companies that concentrate on one facet of the process.

Printing volumes

Printing numerous sheets of card stock or labels in a short period of time can create printing problems. Continuous printing on labels, for example, may result in more frequent service calls. The glue on the labels can be squeezed out by the rollers in the printer and contaminate other printer parts. Most labels and card stock have cuts or perforations that can be abrasive if not ironed or flattened.
Special media, in general, have rough coatings and are thicker.
Proper printer maintenance can help you avoid these problems. For information about maintaining your printer, see “Maintenance procedures” on page 14.

Testing print material

Consider the following factors when choosing print materials:
Physical characteristics of the base stock and the manufacturing processes, which are dependent on the vendor,
may change over time.
The quality of print materials can also affect printer reliability and downtime. Using materials from converters or
vendors who are unfamiliar with laser printing may result in unsatisfactory print quality or other printing problems.
Once a design is finalized, test the print material before placing a large order to avoid costly mistakes.
General information 9
Your print materials supplier should be able to help develop your application or solve a problem you have with an existing application. In addition, Lexmark has worked with several suppliers and has business partners in this field. For technical assistance contact numbers, see the printer registration card, information on the printer CD, or visit the Lexmark Web site at
http://support.lexmark.com.

Design factors

Print materials all have measurable characteristics that you need to consider when selecting or designing forms for your particular application.
Basis weight
Basis weight is a term used to describe the weight in pounds of 500 sheets of paper (one ream). However, the weight is determined based on the standard size of the paper, which may not be the purchased size. For example, the standard size of 20lb bond paper is 17 x 22 inches, and a ream of 17 x 22‑inch 20‑lb bond paper weighs 20 pounds. If the 17 x 22inch 20lb bond paper was cut, creating four reams of 8.5 x 11inch paper, each ream would be labeled 20lb bond paper but would only weigh five pounds.
If the same paper weighed 24 pounds, it would be called 24lb bond. The 24lb bond paper is thicker, heavier, and more dense than the 20lb bond. Thicker paper means less paper can be placed in a tray, and paper that is heavier and more dense may cause paper jams or feed reliability problems in some printers. Check the supported paper weights table located in the printer documentation to verify that the paper basis weight being used is acceptable.
Not all basis weights are related to the same standard sheet size: for example, 70‑lb material can be lighter than 40‑lb
2
material if it is based on larger base size paper. The metric measurement of grams per square meter (g/m consistent way to compare weights and has been standardized by the International Organization for Standardization (ISO). For more information, locate your printer in the “Printer specifications” chapter.
Your printer can accept a wide range of stock weights, but materials either too light or too heavy can cause printing problems. Heavy and/or thicker materials may not heat quickly enough in the fuser, resulting in poor print quality. They may also feed less reliably or skew due to their weight or rigidity. Conversely, lighter materials can wrinkle and jam in the printer due to low beam strength (stiffness).
Depending on the orientation of the stock as it feeds through the printer, you may need to request that heavier materials be cut grain short or grain long to provide flexibility in paper path turns. For more precise recommendations, locate your printer in the “Printer specifications” chapter.
) is a more
Dimensions
All printers have print material dimension limitations. See the printer documentation that came with your printer for details. You can sometimes redesign forms to overcome these limitations. For example, if you use forms that are shorter than the minimum length supported by your printer, you may be able to link two forms together when printing multiple forms. An optional Universally Adjustable Tray designed for the Optra S, Optra T, and Lexmark T printer families prints on a range of paper sizes including A6 and 3 x 5inch index cards, 3 x 7inch punch cards, and 4 x 6inch postcards.
Environment
Lexmark printers meet or exceed all industry emission regulations and standards. Continuous printing on some papers or other media may create fumes that are not a problem with occasional printing. Make sure your printer is located in a wellventilated area.
Temperature and humidity can have a major impact on printing. Even small changes (such as from day to night) can greatly affect feed reliability if the print material is just within the range of acceptability.
General information 10
We recommend that you condition stock while it is still in the original wrapper. To condition stock, store it in the same environment as the printer for 24–48 hours before printing to let the stock stabilize at the new conditions. You may need to extend this time by several days if the storage or transportation environment is very different from the printer environment. Thick stock may also require a longer conditioning period because of the mass of the material.
If you remove the wrapper from the stock before you are ready to load it in the printer, the stock may develop uneven moisture content that can cause curl. Prior to loading your stock, we recommend that curl not exceed 3 mm (0.125 in.). Lighter materials, such as paper labels and some integrated forms, are more likely to have printing problems if curl is present.
Most label manufacturers recommend printing in a temperature range of 18–24°C (65–75°F) with relative humidity of 40–60%. Lexmark printers are designed to operate in a temperature range of 15.5–32°C (60 to 90°F) with relative humidity of 8 to 80%. Printing in an environment outside these recommendations may cause jams, feeding problems, reduced print quality, and predispensing (peeling) labels.
Inks (preprinted stock)
Preprinted stock introduces semiliquid and volatile components to the high temperatures and pressure used in the laser printing process. Preprinted inks and colorations must withstand a fuser temperature up to 225°C (437°F) and pressure up to 25 psi without contaminating the printer or creating hazardous fumes.
Thermography inks are not recommended. Thermography inks have a waxy feel and the printed image appears raised above the surface of the print material. These inks can melt and damage the fuser assembly.
Preprinted inks must also be abrasion resistant to reduce ink dust and ink contamination in the printer. If you are printing over a preprinted area, the ink must be receptive to toner to ensure adequate fusing.
All preprinted inks must be thoroughly dry before using printed materials. However, we do not recommend using offset powders or other foreign materials to speed drying. Check with your converter, or the manufacturer or vendor of the ink you plan to use, to determine if the ink is compatible with laser printers that heat the ink to 225°C (437°F).
Perforations and diecuts
If your form has perforations, the perforation line should stop 1.6 mm (0.06 in.) from each edge of the form to avoid separating the form in the printer path, resulting in a jam. The location of the perforation affects initial pick strength. Perforations closer to the edge may increase the number of jams. For pressuresensitive materials such as labels, minimize the number of perforations that go through the backing material, or liner, since these can also affect the strength of the form.
Perforations should be ironed so the print material lies flat, reducing nesting of forms. Edges should be smooth and
clean with no roll‑over. Laser These smaller perforations do not normally nest or create excessive paper dust and debris. Make sure paper chaff and dust created during the conversion process are removed before packaging.
If perforations tent, or crease at the perforation line, the perfs may break, causing a paper jam. Tenting may increase skew, cause doublesheet feeding, or smear the toner on the print material before fusing, resulting in poor print quality. To reduce tenting, use microperfs. If the print material is lightly snapped as it moves through the printer, the perforations should hold without breaking.
perfs (also known as micro‑perfs or data‑perfs) provide greater stability and are preferred.
cutting is used to create shapes in a label or a card stock design. When designing labels, round all corners to prevent
Die
delamination of the labels, and avoid cuts through the liner (anvil cuts). Back splits and popout windows are also not recommended.
If perforations or diecuts are part of the design of the print material, ties are recommended. These small uncut areas (approximately 1.6 mm or 0.06 in.) help stabilize the form and prevent tearing at perforations and diecuts during printing.
General information 11
For areas with diecuts or perforations that create a small end product, or where diecuts or perforations intersect, ties on the corners of the design provide added stability. Ties may be located anywhere along perforations or diecuts. For pressuresensitive products, ties help prevent the labels from peeling off the liner while in the printer. Ties cannot, however, be used to compensate for inadequate release strength of the adhesive in label designs.
For specific perforation and diecut guidelines for your printer, locate your printer in the “Printer specifications” chapter.
Debossing and embossing
Avoid debossing and embossing materials. Embossing leads to nesting and doublesheet feeds, and the fusing process significantly reduces the height of the raised image. Printing too close to embossments results in poor print quality and poor fuse grade.
Metallics
We do not recommend using metallics in forms, whether in inks or other materials, due to their conductivity and their ability to bleed charge. This can interfere with toner transfer and cause poor print quality.
Basic form design
When designing forms, include a nonprint area of 8.38 mm (0.33 in.) at the top and bottom of the form and 6.35 mm (0.25 in.) on both sides of the form.
In general, portrait orientation is the preferred layout, especially if you are printing bar codes. If your forms require landscape orientation, be aware that variations in paper path speed may produce spacing variations when printing bar codes.
Note: We do not warrant uninterrupted or error‑free operation of a product. Warranty service does not include repair of failures caused by:
modification or attachments
accidents or misuse
unsuitable physical or operating environment
maintenance by any unauthorized (nonLexmark) servicer
operation of a product beyond the limit of its duty cycle
failure to have installed a maintenance kit as specified (if applicable)
use of printing media outside of Lexmark specifications
use of nonLexmark supplies (such as toner cartridges and/or inkjet cartridges)
use of nonLexmark product or component

Pick roller technology

Some printers have an auto compensator which feeds paper more reliably than the corner buckler system used by earlier printer models. The auto compensator has two rollers that touch the media. Avoid placing deep perforations in these areas since the media may nest, causing multiple sheets to feed. Perforations that could cause nesting and tenting should fall outside the pick roller area on the leading edge of the media. This is different from the 0.50inch space we recommend leaving at the top of the form for printers with a corner buckler system. You may want to use micro‑perfs to avoid nesting problems. For more information, see “Perforations and diecuts” on page 10.
General information 12
For the following printers, make sure perforations fall outside the 0.3–0.79‑inch area on the leading edge of the media: Optra S, Optra T, T520, T522, T620, T622, T630, T632, T634, T640, T642, T644, T650, T652, T654, T656dne, X203, X204, X264, X363, X364, X463, X464, X466, X543, X544, X546dtn, X560n, X642e, X644e, X646e, X651, X652, X654, X656, X658, X734, X736, X738.

Maintenance procedures

Note: These procedures apply only to mono laser printers.
If print quality begins to degrade when printing on vinyl labels, then do the following:
1 Print on five sheets of paper.
2 Wait approximately five seconds.
3 Print on five more sheets of paper.
To maintain printer feeding reliability, repeat this cleaning process every time you replace the toner cartridge.
Note: Failure to follow maintenance procedures for your printer could cause jams, poor print quality, feeding problems, and fuser problems.

Troubleshooting

The following table provides solutions to some common card stock and label problems. For more troubleshooting information, see your printer documentation.

Card stock

Card stock is a rigid, stiff material that can have a wide variety of constructions. Orientation of paper fibers (grain direction), moisture content, thickness, texture, and other properties can significantly impact printing, as can preprinting, perforation, creasing, and other features common to forms. For example, preprinting introduces semiliquid, volatile components that must withstand the high temperatures used in laser printing. Perforation and creasing may cause nesting, or interlocking, which can cause paper jams and double-sheet feeds.
In general, we recommend a singleply construction of 100% chemicallypulped wood with a vellum finish. Before purchasing large quantities of card stock, make sure you test samples of the print material in your printer.

Weight

The weight of card stock significantly affects the print quality and feed reliability of the stock. Specify the correct basis weight of a stock. For more information, see “Basis weight” on page 9.
Basis weight is the weight in pounds of one ream, or 500 sheets, of paper. Since the sheet size varies from one type of stock to another, basis weights are not always easily comparable. For example, an office supply store has 8.5 x 11‑size cover stock (80 lb Bristol) and 8.5 x 11size card stock (90 lb Index) side by side on the shelf. Both papers are manufactured by the same company, and a basis weight comparison indicates the card stock (90 lb Index) is heavier than the cover stock (80 lb Bristol). In this case, however, the cover stock (80 lb Bristol) is actually heavier than the card stock (90 lb Index).
Before the two types of paper were cut into 8.5 x 11‑size pages, the card stock was a larger sheet size than the sheet size of the cover stock. When the papers were cut during the manufacturing process into 8.5 x 11size pages, more reams (500 sheets) of paper were received from the card stock sheets than from the cover stock sheets. This makes the weight of the cover stock heavier than the weight of the card stock.

It is easier to compare the cover stock metric weight (g/m metric weights of the two stocks in the previous example, it is immediately evident that 80 lb Bristol cover stock

Not all printers are able to print on cover stock. This is because cover stock is usually thicker and not able to make the turns in the printer paper path. This causes paper jams and sometimes causes the paper to feed incorrectly. Also, when using a laser printer, toner is pulled onto the paper through an electrical charge. If the paper is too thick, then there may not be enough voltage to pull the toner onto the paper properly, resulting in poor print quality.
To determine if your printer supports cover stock, see the section for your printer in the "Printer specifications" chapter and review the supported paper type information. You can also view the supported paper types in the documentation that came with your printer.

Card stock weights may vary ± 5%.
Depending on the printer, material thicker than 0.30 mm (0.012 in.) may present feed reliability problems, and material thicker than 0.17 mm (0.007 in.) may reduce print quality. Contact your supplier to determine the weight of any card stock you currently use.
See the individual printer specifications in this document for more information about the card stock weights your printer supports.

Grain orientation

Grain refers to the alignment of the paper fibers in a sheet of paper. Grain is either grain short, running the width of the paper, or grain long, running the length of the paper.
The orientation of the grain contributes to the rigidity of card stock and affects feed reliability. The recommended grain orientation depends on the weight of the stock and whether the printer feeds the stock short edge first or long edge first. For lighter card stocks, grain long is recommended to reduce potential curl problems. Curl may decrease the ability of the form to move reliably through the printer.
Most printers feed paper short edge first. If your printer supports larger paper sizes, such as 11 x 17 in. or A3, it may feed some paper sizes long edge first. See your printer documentation for more information.

Coatings

Surface texture and coatings on card stock significantly affect toner adhesion (fuse grade), print quality, and feed reliability. We recommend a vellum finish for the best printing performance. We do not recommend glossy coatings and slick surfaces o r surfaces that mimic laid finishes (glo ssy paper, not glossy card sto ck, is acceptable for some printer s). Paper smoothness also affects print quality. If the paper is too rough, the toner does not fuse to the paper properly; if the paper is too smooth, it can affect feed reliability. We recommend smoothness to be between 100 and 400 Sheffield points (150–250 is optimal). Using media higher than 300 Sheffield could result in printing degradation.
Card stock 19

Offset powders

We do not recommend using offset powders or other foreign materials to speed drying. Offset powders are used by print shops to prevent printed pages from sticking together. Powder is usually sprayed on the printed page right before it reaches the stacker on the offset printing press. This powder provides an intermediate layer between two sheets of paper, preventing ink from transferring from one sheet to another.
Labels 20

Labels

Labels , or pressuresensitive materials, are multiply materials that contain various combinations of face sheets (printable stock), adhesives, and removable protective backings (liners). These layers can result in thick materials that are difficult to handle.
Labels are among the most difficult print materials for any printer to reliably feed and print. Factors such as heat, pressure, and paper path could make printing on labels quite challenging. For example, temperatures near 225°C (437°F) [temperatures vary between printers; check the section for your specific printer] and pressures to 25 psi can be necessary for the fusing process. Heavy label stock can absorb heat, which in turn affects toner adhesion and print quality and causes problems such as delamination.
Note: To prevent labels from peeling off or delaminating, make sure the release strength of the labels is sufficient to withstand the temperature and pressure extremes generated during printing.

Label characteristics

The materials used to construct labels have a wide range of properties that can affect printing. Volatile components are in the label materials and in the adhesive itself. We recommend that volatile emissions from the label, up to 160°C (320°F), should be a minimal amount. The volatile components, which have low boiling point, produce emissions when heated in the fuser and could emit vapors that can damage the printer.
Preprinted inks can also cause printer contamination, and may be present on one or both sides of the label sheet.
Follow the recommended label design guidelines to prevent labels from peeling off, which could cause jams. The label or adhesive could also melt if the sheet is jammed in the fuser.
Review label designs with a converter or a vendor who has extensive knowledge about labels and laser printers to ensure that you are using the proper type of labels.
Before purchasing large quantities of labels, make sure you extensively test the labels with your printer.

Printing on labels

Print on full label sheets only. Sheets with missing labels could peel off during printing and result in a paper jam. Partial sheets can also leave adhesive marks on the printer and cartridge, which could void the printer and cartridge service warranties.
Do not feed labels through the printer more than once. Doing so may contaminate the cartridge and other components with adhesive.
Depending on your printer model and the number of labels being printed, printing labels may require special printer maintenance. For specific maintenance information, see the documentation that came with your printer.
For more information about printing on labels, see the section for your printer in the “Printer specifications” chapter.

Duplexing paper labels

Labels are not typically duplexed because of their special construction. However, printing on both sides of the label sheet may be possible if certain design, construction, and usage guidelines are followed.
Labels 21
When developing a paper label for duplexing, the converter should make sure that the label is designed to protect against contamination or buildup. Contamination could result in paper feed problems and paper jams.
We recommend the use of label sheets that have a non-adhesive border around the label area. Make sure that the release strength is enough to withstand temperatures of 225°C (437°F) and pressure up to 25 psi. The ability to withstand these factors is important because the label sheet will be subjected to these twice.
Use label ties whenever possible. These small uncut areas (approximately 1.6 mm or 0.06 in.) help stabilize the label sheet and prevent tearing at perforations and die-cuts during printing. Label ties also prevent labels from predispensing in the printer.
The slits and cuts in the labels expose the adhesives to the printer. For best results when duplexing labels, position the label sheet so the slits and cuts are not aligned with the ribs in the duplex or redrive areas of the printer. This eliminates any contact points between the label adhesive and the printer, thereby preventing any adhesive contamination in the printer. The following graphics show the rib locations for the Optra S, Optra T, and Lexmark T, respectively.

Load label sheets with the label end first. Use grain long paper instead of grain short paper, which tends to curl easily.
If a converter develops a grain short lab el sheet for duplexing, then test the sheet first to make sure it works satisfactorily.
Note: We recommend testing any material with your application and printer before purchasing large quantities.
To use the duplex label application, you must install a special fuser wiper.

The wiper makes it possible to print on both sides of paper labels specifically designed for duplexing. You may also use the wiper when using the printer to print on one side of a label sheet or both sides of a sheet of paper. When ordering a new cartridge, be sure to order the cartridge that includes the correct fuser wiper.

Primary rib pattern design guidelines for reference edge alignment

The function of the primary rib pattern is to provide the best support to the media during transport. If it is known that the media will be touching a certain surface, then that surface must contain the primary rib pattern.
The feed path should guide the leading edge of the media into the primary guide surface and not the secondary surface. This provides a determinate location for the leading edge of the media on the guide surface that provides the best support.
The incidence angle of the leading edge of the media as it touches the primary guide surface should be no more than 30°. This eliminates media stubbing on the guides and reduces the amount of energy input into the media by the guide.
The primary rib pattern is to have the rib support extending out to between 3 to 10 mm from the edge of the paper and 2 to 10 mm from the edge of the envelopes. This keeps the corners of the media stiff so that it cannot fold and catch other surfaces in the printer. It also prevents the corners of the media from catching the inside surface of a paper path rib.
The primary rib pattern should not have any ribs closer than 3 mm to the outside edge of paper and envelopes. This keeps the media from stubbing into a rib that is too close to the edge of the media.
The maximum rib spacing of the primary rib pattern should not be greater than 20 mm. This keeps the leading edge of the media flat as it moves through the system.

Label components

Labels are composed of three basic parts: the liner, the adhesive, and the face sheet. Labels may also have topcoats that affect printing. Choosing appropriate materials for each of these label components will help ensure reliable printing.
Liners
The liner, also known as the carrier or backing, is the material onto which the label is attached. The liner carries the label through the printer and directly affects feed reliability. Liner weights and construction vary based on the printable face stock used. For more information, see “Face sheet (printable stock)” on page 25.
Tissuebacked, plain bond, or bondlike, porous, layflat liners are preferred. Liners constructed for use with high‑speed laser printers (50 or more pages per minute) may not produce acceptable results.
A liner should bend easily and go back to its original flat state when released. If the form remains bent, then it may cause paper jams or damage to the edge of the sheet, particularly in earlier printer models using a corner buckler rather than an auto compensator to separate the sheets. The following table shows which printers use a corner buckler and which use an auto compensator.
Note: If your printer is not listed here, then contact your Lexmark representative to verify which method your printer uses to separate sheets of labels.

Some liner materials used in pressuresensitive constructions are called label papers. Label papers are either machine finish (MF) or English finish (EF) papers that are calendered, supercalendered, or coated on one side. An MF has varying degrees of surface smoothness. The smoothness is determined by the number of times the paper passes through the rollers (wet or dry) during manufacturing. An EF is uncoated and low gloss in appearance. Label papers may also be used as the face sheet for pressuresensitive paper products, such as the materials used in dual web forms construction.
Supercalendering produces high gloss surfaces that may be slick. Some supercalendered liners are difficult for printers to pick and feed reliably. We do not recommend using supercalendered liners designed for highspeed laser printers (50 or more pages per minute).
Some pressuresensitive constructions use Kraft liners or bleached Kraft liners. Kraft liners are made from sulfate pulp and are MF or machine glazed (MG). Most MG papers have a high gloss appearance. High gloss, glazed surfaces may increase skew and are more difficult for the printer feed mechanism to handle reliably. Some Kraft liners may produce acceptable results; however, we strongly recommend extensive testing of pressuresensitive constructions using Kraft liners.
Tissuebacked or plain bond liners reduce toner contamination inside the printer and improve feed performance. Slick, nonporous liners are harder to feed and increase toner buildup in the fuser and on the backup roll. Rough backings, on the other hand, can increase paper path friction, which can cause skew and paper jams. The face material of the liner needs to have a melt temperature that can also withstand the fuser temperatures of nearly 225°C (437°F). Since there is a stripped area of a maximum of 3 mm, this can expose the face material to these temperatures and could cause melting or contamination in the fuser.
Excessive paper dust or chaff associated with the liner may affect print quality. If a liner material produces excessive paper dust or chaff during the conversion process, some of this debris may be packaged with the material and end up in the printer. Liner materials that produce excessive paper dust or chaff as they feed through the printer may also affect print quality.
Your forms supplier can provide additional information on liners.
Adhesives
There are three basic types of label adhesives: removable, permanent, and semipermanent (cold temp). All types, with proper design, can be used with your printer. Acrylicbased adhesives are generally preferred for cutsheet label printers.
Labels 25
The major adhesiverelated printing problem is printer and cartridge contamination. The adhesives are semiliquid and may contain volatile components. If the sheet jams in the fuser, the adhesive can melt, thereby contaminating parts of the printer or releasing fumes. To avoid exposing adhesive to the paper path guides, drive rollers, charge roller, photoconductor drum, transfer roller, and detack fingers, use full label sheets.
Zone coating means placing the adhesive only where needed. Paper labels and integrated forms typically use zone coating. In addition, a nonadhesive border of 1 mm (0.04 inches) around the outside edge of the label sheet generates good results. Check with your adhesive manufacturer or forms supplier for more information about designing labels for your printer.
A stripped edge matrix along the outer border of the stock, combined with adhesive that does not ooze, helps prevent adhesive contamination. This design requires a stiffer backing material to prevent damage when the sheet is aligned on the reference edge. Generally, vinyl and polyester labels are wellsuited for this design. Paper and dual web designs may require testing to determine which backing produces good results. For more information on matrices, see “Label design guidelines” on page 25.
Make sure the release strength is adequate so labels stay attached to the liner and do not peel off in the printer. Adhesives must be able to withstand pressures to 25 psi and fuser temperatures of 225°C (437°F) without delaminating, creating hazardous fumes, or oozing around edges of labels, perforations, or diecuts. Shear strength should be strong enough to prevent adhesive stringers. For more information, contact your forms supplier.
Face sheet (printable stock)
Paper, vinyl, and polyester are the most common materials used for printable stock. Your forms supplier can provide information on whether the printable stock you want to use can withstand temperatures up to 225°C (437°F) and pressures up to 25 psi. Carefully test the stock to make sure it functions satisfactorily with your printer.
Note: Temperatures vary by printer. For more information, see the section for your printer.
Topcoats
Topcoats for nonpaper labels may be either waterbased or solventbased. Avoid topcoats containing chemicals that emit hazardous fumes when heated or exposed to pressure. Topcoats affect the print quality, feed reliability, and adhesion of toner to the face sheet. Topcoats must be able to withstand temperatures up to 225°C (437°F) and pressures up to 25 psi for 100 milliseconds to prevent fuser damage.
Note: Temperatures vary by printer. For more information, see the section for your printer.
Waterbased topcoats tend to be more conductive than solventbased topcoats and are more difficult to fuse. With some waterbased topcoats and heavy liners, the fuse grade may fall below acceptable levels. Solventbased topcoats tend to be lower in conductivity than waterbased topcoats. With some solventbased topcoats, fuse grade is within acceptable levels when heavier liners are used.
Print quality may degrade when using topcoats on labels with heavier liners. Using a lighter liner may reduce the appearance of splatter. Carefully test the forms to make sure the topcoat functions satisfactorily with your printer.

Label design guidelines

Labels with a stripped edge matrix do not have the area around the outer edge of the cut sheet. Labels with a total strip matrix do not have the diecut stock around and between the labels. This makes it easy to peel the labels from
the backing.
Butt cut labels are cut flush to one another, with no extra area between them. Avoid using butt cut labels without a stripped edge matrix.
Labels 26
Die‑cut labels are cut with a nonprint area between each label. For best results, do not print within 2.3 mm (0.090 in.) of the edge of the label, of the perforations, or of the diecuts of the label.
If you are using a butt cut or diecut label, then make sure adhesive contamination does not occur. Labels use varying levels and types of adhesive, as well as a variety of liner materials and facestock papers. Adhesive can ooze from all label stocks. Make sure diecuts are free of adhesive stringers. To prevent adhesive contaminations, use zone coating or pattern adhesive with a nonadhesive border of about 1mm (0.04in.) or larger.
If zone coating is not used, then we recommend a stripped edge matrix. The stripped edge matrix varies with the type of face stock, liner, and adhesive materials. See the following table for stripped edge matrix guidelines. Measurements may vary ±0.5 mm.

Using cut sheet labels with adhesive applied to the edge of the sheet will contaminate your printer and your cartridge and could void your printer and cartridge warranties.
When using pressuresensitive materials without zone coating, choose butt cut labels without any stringers and with a stripped edge matrix. If a total strip matrix is in the design for the final product, then print before removing the matrix. If the matrix must be removed before printing, then round all corners and make sure adhesive is not exposed.

Cut sheet paper labels
Generally, cut sheet paper labels work well with your printer.
Coating or sizing to make the paper liquidresistant decreases toner adhesion and increases the risk of toner
contaminating the fuser. At a minimum, paper labels should be equivalent in weight and rigidity to a 20‑lb xerographic bond paper.
Dual web forms
Constructing dual web forms involves joining together rolls of two different materials (usually pressure‑sensitive
paper and bond paper) and then converting to a cut sheet product.
This construction requires a stripped edge matrix. The liner must be rigid enough to withstand the pick force of the
printer.
Labels 30
The two materials must be thin enough for the sheet to lie flat in the paper tray. Orient the form in the tray so that
the pressuresensitive area feeds into the printer first. The form should have no adhesive exposed in the overlay area or anywhere along the front or back of the form.
We recommend designing a non‑adhesive strip with a minimum width of 1 mm (0.04 in.) along the edges of the
overlay.
To help prevent material from slipping in the fuser, we recommend knurling, which roughens up the exposed silicon
area at the glue joint.
The face sheet of a dual web form is usually a paper pressuresensitive product; therefore, the guidelines for paper
labels are applicable to dual web forms.
The following diagram shows the recommended dual web form design. The non‑print area may vary, depending
on the printer model.

Vinyl and polyester labels
Vinyl labels work well within specified design parameters. Vinyls are heat‑sensitive, so the liners need to be thick
