PREFACE

Printing on non-porous materials has always been a major problem in industrial applications. The high degree
of maintenance usually required to keep conventional “non-porous” machines operating has made many com­panies opt for manual marking as a cost effective alternative. UNIVERSAL changed all that with our patented
Non-Porous Inking System design. Previously available only on conveyor line mounted coders, this same
technology is now available on the new Universal Non-Porous Hand Printers.

Printing on non-porous materials can now be accomplished with the same relative ease as printing on porous
materials. This breakthrough in Non-Porous coder design opens up in-plant printing opportunities which previ­ously were regarded as too difficult to consider.

Unlike the inks used to print on porous materials which dry through absorption into the material being printed,
non-porous inks rely on the rapid evaporation of the ink solvents to achieve fast drying of the printed marks.
Since the ink solvents must evaporate very rapidly on the printed material, they also evaporate very rapidly from
the ink rolls and ink wells of conventional printers therefore requiring constant maintenance.

The proprietary design of the UNIVERSAL Non-Porous Inking System ef fectively eliminates the rapid evapora­tion of the ink solvents from the ink roll. The final design of this system was the product of many months of
design engineering and field testing. The final product is both simplistic in design and extremely effective in
operation. The relatively low cost of these systems makes in-plant printing of all types of non-porous materials
a practical reality . The following pages of this manual explain the operation and maintenance of the Non-Porous
Hand Printers and are the key to trouble free non-porous printing.

This manual was written with a full understanding that very few people like to read manuals or have the
time to do so. To accommodate those who have little time to spare, we have included a Quick Start
section which will get your coder operating in just a few minutes.

To keep your coder operating properly, it is important to read and understand the Basic Principles of
Operation section which explains the basic operation of the Non-Porous Inking System.

INDEXING & NON-INDEXING MODELS

Universal Non-Porous Hand Printers are available from the factory in both indexing and non-indexing models.
Indexing Hand Printers contain a cam & spring return mechanism (see Figure 1) which returns the print drum to
the same rotational position after every imprint is applied. This feature provides print registration capabilities
when printing on cut sheets of material or the sides of varnished or waxed cartons.

Non-Indexing Hand Printers have print drums which simply rotate on bearings and repeat the print at an interval
equal to the circumference of the print drum. If repeat intervals shorter than the print drum circumference are
required, duplicate sets of dies can be installed on the print drum. Non-Indexing Hand Printers are generally
used for printing on long lengths of material where it is desirable to print the same code repeatedly down the
entire length of material.

RIBtype® PRINTING DIES

Universal Non-Porous Coders are designed to use RIBtype® rub­ber type, printing dies which have a molded rib backing. The ribs
on the back of the die snap into mating ribs in the Drum Cover on
the print drum as shown.

The printing dies are produced in many standard character styles
and sizes and are available in sets containing a combination of
individual alphabetic and numeric characters or in sets containing
numeric characters only. These character sets or “sorts” can be
used to make up text messages and code numbers as necessary .

FIGURE 2

Dies are also available in “logo” form in which a complete text message is produced on a single piece of rib
backed rubber. Logo dies are much faster to change and generally produce better print quality due to their
unitized construction. Custom type styles, company logos, and trademarks can also be photographically repro­duced from black and white art work. For details on ordering custom logo dies, please contact our Customer
Service Department.

Printing dies are manufactured to precision thickness tol-

BEARER RING

erances which are very critical to the performance of these
coders. When installed, the face of the printing die should
extend only .007" - .008" beyond the radius of the Bearer

.007” - .008”

Rings as shown. Using dies that do not meet the design
specifications will result in poor print quality and possible
damage to the transfer roll.

PRINTING DIE

Although there are several competitive rib backed die sys-

tems available, it is very important to note that they are not
all made to the same rib spacing or thickness specifica­tions and they are not interchangeable.

FIGURE 3

CODER MODELS DESIGNED FOR METRIC RIBtype® PRINTING DIES

Universal also offers Metric RIBtype® Die systems for use in countries where metric character sizes are the
standard. The Metric dies are thicker and the rib spacing differs slightly from the standard printing dies therefore
the two versions are not compatible. To accommodate the differences, the print drums for Metric dies are
machined to a slightly different diameter from the U.S. versions.

The coder model numbers on Metric coders will have a “-T” suffix and the Metric Drum Covers have a distinct
pink color.

SPECIFICATIONS

INK ROLLS

Universal offers two ink roll options for the Non-Porous Hand Printers. The coders are designed to accommo­date both types of ink rolls without modification. A detailed review of your printing requirements will determine the
best choice of ink rolls for your particular application.

XF NEOPRENE INK ROLLS

Universal’s XF Neoprene Ink Rolls are a re-inkable roll which can
be used with a variety of alcohol or glycol base inks. These rolls
are normally supplied in a dry condition with the coder and require
pre-inking prior to installation. Pre-inked rolls are available from
the factory and are recommended for first time users.

Universal’s #100 Inks provide drying times of approximately 2 sec­onds at 75 Degree F. (24 Deg. C) ambient temperature. Many
other inks, both dye and pigment based, can be used in these ink
rolls to meet the specific application requirements. Refer to the
Basic Principles of Operation section for more information on se­lecting an appropriate ink.

FIGURE 4

TYPE MT INK ROLLS

Universal’s Type MT Ink Rolls are disposable pre-inked rolls which
are available in Black only . The MT Ink Rolls provide excellent color
density and adhesion on most materials and yield a much greater
number of impressions than the XF Neoprene Rolls before replace­ment is necessary.

The T ype MT Ink Rolls provide drying times between 4 - 7 seconds at
75 Degree F. (24 Deg. C) ambient temperature. The added conve­nience and simplicity of using the T ype MT Ink Rolls makes them an
ideal choice in high volume production applications.

QUICK ST ART

Warning: Non-Porous inks contain flammable solvents. Do not smoke or handle these rolls in the
presence of sparks or open flames. Inks will also stain clothing, furniture, carpeting and your hands.
Rubber gloves should be worn during the following procedures.

INSTALLING THE PRE-INKED ROLL

The ink roll you install on the coder must be properly pre-inked. If your coder was supplied with a dry XF

Neoprene ink roll, refer to the Maintenance Section for inking instructions.
Rollers that have been pre-inked at the factory are slightly oversaturated with ink to compensate for potential

solvent loss during shipping and storage. If you received a pre-inked ink roll with your coder, it is important to
examine the roll prior to installation. The ink roll should be thoroughly saturated with ink but not dripping
wet. Excess ink can be easily removed by lightly rolling the ink roll across a clean piece of absorbent paper.

1 - To install the pre-inked roll, first turn the Ink Roll Ec-

centric Adjusting Knob “A” to the “MIN” position.

This moves the ink roller axle away from the Transfer Roll
and enables the ink roll to be installed without interference
with the Transfer Roll during reassembly of the inking sys­tem.

The ink roll you install on the coder must be Pre-Inked. If
your ink roll is not saturated with ink refer to page 15 for
inking instructions.

7 - Using the Core Hub, push the Ink Roll fully onto the

Core.

8 - Inspect the Ink Roll closely for excess ink content. The

roll should be fully saturated but not dripping wet. If the
roller appears to be excessively wet, place a screwdriver
through the core and roll the ink roll across a clean piece
of paper or cardboard to remove excess ink.

Installing an oversaturated ink roll on your coder will result in
poor print quality and possible ink leakage problems.

9 - Install the Ink Roll assembly on the Ink Roll Axle.

It does not matter which end of the Ink Roller Assembly
goes on the axle first.

orientation to fit back onto the Inking System Housing and
carefully guide the Ink Roll into the large cavity.

INSTALLING THE PRINTING DIES

Printing Dies can be installed on your new printer with the print drum in place or for more convenient installation,
the print drum can be removed from the coder.

1 - To remove the Print Drum from the coder, grip the Print

Drum to prevent it from turning and remove the Print Drum
Knurled Nut by rotating it counterclockwise.

FIGURE 17

2 - Lift the Print Drum off the Bearing Hub Assembly.

FIGURE 18

3 - Align the ribbed backing on the Printing Dies with the mat-

ing Print Drum covering and press firmly until they are com­pletely engaged. It is best to install the dies as close to the
middle of the print area on the Print Drum as possible.

Individual character codes or text messages are installed in a
mirror image of normal written text. In other words, install in a
right to left direction as shown. When printed, codes or text in­stalled in this orientation will print in normal left to right order .

FIGURE 19

To make die installation easier, moisten a sponge with water containing a small amount of liquid detergent.
Lightly moisten the back of the printing die and then immediately press the die into the drum cover. Note: Do not
apply too much liquid or the dies will slip during printing.

Note: Do not apply silicone, oil or any other lubricating agent to the rib backing or the dies will not hold
properly during printing. Some lubricants will permanently damage the Drum Covering and Printing
Dies.

4 - When using the smaller individual characters to make up a

code message, use the T ype Blocking Kit included with your
coder to support the leading and trailing ends of the type
as shown.

Characters with only a 2 or 3 rib backing do not have the stabil­ity of the larger sizes when snapped into the drum cover. Add­ing the rib backed type blocks on either side of the code will
provide added stability . The T ype Blocks are not as thick as the
Type and will not pick up ink from the Transfer Roll.

5 - Reinstall the print drum on the Hub Assembly and re-

place the Print Drum Retaining Knob.

FIGURE 20

FIGURE 21

ADJUSTING THE DIE POSITION ON INDEXING PRINTERS

The print drums on indexing coders always return to the same rotational or “indexed” position after every print is
applied and the print drum is lifted off the surface of the material being printed. In order to ensure that fresh ink is
applied to the die faces on every printing cycle, the dies should be positioned rotationally upstream of the T ransfer
Roll when the print drum is in the indexed position.

1 - T o position the printing dies, slightly loosen the Print

Drum Knurled Nut. Rotate the Print Drum as neces­sary to bring the leading edge of the die into the posi­tion indicated and then hold the Print Drum stationary
while tightening the Print Drum Knurled Nut to lock
the Print Drum in place.

When the printer is used with the leading edge of the printing
die positioned as shown, the printing dies are immediately ro­tated past the anilox roll where the ink is applied and then the
impression is immediately transferred to the surface of the
material being printed.

ADJUSTING THE INK ROLL ECCENTRIC

The Ink Roll is mounted on an axle which is position adjustable by rotating the Ink Roller Eccentric Adjusting
Knob. This feature is designed to provide compensation for slight variations in Ink Roll diameters. With the Ink
Roller Eccentric set at the “MIN” position, the Ink Roller will not make contact with the Anilox Roll. The position of
the Ink Roll needs to be adjusted so that it makes adequate contact with the Anilox Roll in order for it to transfer
ink properly. Too light a contact will result in the printing die not receiving enough ink to print and too heavy a
contact will apply excessive ink to the printing die.

1 - To find the proper position for the Ink Roll, rotate the

Eccentric Adjusting Knob from the “MIN” to the “1” posi­tion.

FIGURE 23

2 - Rotate the Print Drum and examine the face of the print-

ing dies for signs of ink. If no ink has been applied to the
die faces, rotate the Eccentric Knob a little more towards
the “MAX” position. Repeat this procedure, examining
the die faces each time, until the dies are fully coated
with ink. Typically, the ink roll will make proper contact
with the Anilox Roll when the Eccentric is near the “2”
position.

3 - Apply a test print on a scrap of material and inspect the

impression. Make further adjustments as necessary until
a clear mark is applied with each test print. As soon as
you are satisfied with the print quality, the unit is ready
for production printing.

BASIC PRINCIPLES OF OPERATION

Universal Hand Printers are in essence rotary rubber stamping machines. Applying text images from a flat
printing die requires very uniform contact pressure and a very flat surface to transfer a good quality image. By
wrapping a flat die around a print drum and applying the impression in a rolling motion greatly reduces the
contact pressure required and minimizes the adverse affect of an irregular surface. An additional benefit of
rotary stamping is the ability of the system to automatically apply ink to the die face in a very controllable method
thus eliminating smudged impressions caused by over-inking.

Applying text images to non-porous surface such as metal, glass, rubber or plastic, requires the use of specially
formulated inks which introduce an additional set of problems to the process. Understanding the mechanics of
non-porous printing is essential to a successful operation and Universal’s patented method of handling these
special inks is the solution.

INKING SYSTEM DESIGN

Inks designed for printing on non-porous surfaces contain very fast drying alcohol solvents, a component to
impart color which can be either a liquid “dye” or a finely ground solid or “pigment”, and a resin material which
binds the color medium to the surface of the material being printed. When the printed marks are applied by the
printer, the solvents evaporate rapidly from the printed impressions leaving only the dried resin and color.

Solvent base inks that evaporate rapidly at room temperatures to produce fast drying impressions will also
evaporate rapidly from an ink pad or roll if it is exposed to atmosphere. Preventing rapid solvent loss from the
inking system, which would cause the ink roll to dry out, has traditionally been a very difficult task. Universal’s
patented Non-Porous Inking System design has overcome this problem by enclosing all of the inking system
components in a tightly sealed housing.

The two main components of the inking system, as shown in
figure 26, are the Ink Roll and the Transfer or “Anilox” Roll.
Both of these component parts reside in separate precision
machined cavities in the Inking System Housing. When the
Inking System Cover is installed, the minimal clearance be-

INK ROLL

tween the Housing walls and the Anilox Roll surface provides
an extremely small air channel for solvent vapor to escape.
With this design the printers can be left idle for days with the
ink rolls installed without adverse affect. The same ink roll left
exposed to atmosphere would dry out in a matter of minutes.

The finely engraved surface of the Anilox Roll in this system

also functions as an ink metering device. Applying a very thin
film of ink to the face of the printing dies not only prevents
smudged impressions caused by over-inking but it also re­duces the drying time of the impressions by minimizing the
amount of solvent being transferred.

FIGURE 26

INK OPTIONS

Although the standard #100 Inks are suitable for most non-porous printing applications, other alcohol base inks,
including a variety of pigmented stencil inks, can be used in these coders. It is extremely important, however , to
test the compatibility of the ink with the XF Neoprene Rolls. When fully saturated with ink, the Ink Roll must not
exceed 2.030” diameter. MEK base inks are not comp atible with the XF Neoprene Ink Rolls.

MAINTENANCE

PRE-INKING THE XF NEOPRENE INK ROLL

Warning: Non-Porous Inks contain flammable solvents. Do not smoke or handle these rolls in the
presence of sparks or open flames. Inks will also stain clothing, furniture, carpeting and your hands.
Rubber gloves should be worn during the following procedures.

A dry XF Neoprene ink roll has the same characteristics as a sponge with the capacity to absorb approximately
1 - 1.5 fluid ounces of ink. Please follow the guidelines below to properly pre-ink your roll

1 - Pour approximately 1-1/2 to 2 ounces of ink into a clean

container.

2 - Carefully place the roll into the container of ink. Using

your finger tips, firmly press down on the side of the ink
roll and then release the pressure. This will force the
air out of the roll and the voids will be filled with ink.
Turn the roll over, placing the un-inked side down in the
container. Repeat the process above until the roller is
fully saturated.

3 - Remove the Ink Roll from the container and place the roll

on its side on a plastic bag or some other nonabsorbent
surface. Push the Core into the center hole of the Ink Roll.

FIGURE 27

FIGURE 28

FIGURE 29

MAINTENANCE

4 - Using the Ink Roll Hub, push the Ink Roll fully onto the

Core.

5 - After the initial inking, the Ink Roll will be excessively

wet. To remove the excess ink, place a round shank
screwdriver through the core and roll the ink roll across
a clean piece of paper or cardboard to remove excess
ink.

FIGURE 30

Installing an oversaturated ink roll on your coder will result in
poor print quality and possible ink leakage problems.

FIGURE 31

Y our Ink Roll is now ready for use and should be installed on the coder immediately . If you are not ready to install
the Ink Roll on the coder, it must be placed in a tightly sealed cont ainer for storage to prevent solvent evaporation.
Leaving the roll exposed to atmosphere for even a short period of time will result in the roll drying out and may
render it unusable.

MAINTENANCE

CLEANING THE PRINTING DIES

All inks which are formulated for printing on non-porous surfaces contain a resin binder which bonds the dye or
pigment in the ink to the surface of the material being printed. As the ink begins to dry, this binder becomes
“tacky” or “sticky”. While in this stage of the drying process, the tack on the dies will tend to pick up both airborne
dust and any dust or dirt on the surface of the material being printed. When this happens, the dies should be
cleaned or replaced. The easiest method of cleaning the dies requires the appropriate solvent for the ink being
used, a pair of rubber gloves, safety glasses, an apron to protect your clothing is recommended, a toothbrush,
some clean paper towels and a plastic bag to protect your workbench from staining. (Naturally, the toothbrush
will never be suitable for oral hygiene use after this process.)

After some period of use, the accumulation of contaminates on the dies will cause degradation of the print quality;
cleaning the printing dies, excluding excessive wear to the die face, will restore the print quality of the coder.

1 - Place the contaminated Printing Die on top of several

layers of paper towels to absorb the excess solvent.
Pour just enough solvent on the face of the printing die
to cover the die face.

2 - Using the toothbrush, carefully scrub the face of the

die to remove the contamination and old ink. Add more
solvent as necessary and repeat the process until the
die is clean.

Do not submerge or soak the dies in solvent as this may
cause swelling of the rubber compound.

3 - Blot the surface of the die with a clean paper towel to dry

and reinstall the clean dies on the coder.

FIGURE 32

FIGURE 33

FIGURE 34

17

MAINTENANCE

CLEANING THE TRANSFER ROLL

The surface of the transfer roll is made from DuPont Delrin material and the O.D. of the roll is finely engraved
which enables it to hold a uniform film of ink. This surface material is very fragile and under no circumstances
should you attempt to clean it with anything abrasive.

Warning: Most of the ink solvents used for cleaning are flammable liquids. Follow all safety precau­tions recommended by the manufacturer during this process.

To clean dust and ink residue from the surface of the
transfer roll, first remove it from the coder. Lightly
saturate a soft cotton cloth with the appropriate ink
solvent and gently rub the surface of the roll until it is
clean.

If the ID of the Transfer Roll is contaminated with ink,
the entire Transfer Roll can be submerged in solvent.
A cotton swab may also be useful in cleaning hard to
reach areas.

CLEANING THE CODER

Periodically, the inside of the Inking System Housing
should be inspected for ink residue and dust contami­nation. To remove ink contamination from the sur­face of the machine, moisten a soft cotton cloth with
the appropriate ink solvent and rub it across the con­taminated area.

The frequency of required cleaning can be greatly re­duced if the inking system is kept in proper adjustment
during normal operation and if the ink roll does not be­come over saturated with ink.

CODER REASSEMBL Y INSTRUCTIONS

If for any reason, it becomes necessary to disassemble the entire printer, use the exploded p arts diagram in the
back of this manual for reference during reassembly. There are only 2 critical assembly instructions which
require particular attention as follows:

ADJUSTING THE TRANSFER ROLL TO DIE FACE CONTACT PRESSURE

When reinstalling the inking system housing on the
printer frame, first install Pivot Screw “A”. The Pivot
Screw should be snug but not tight. Install Adjusting
Screw “B” but leave it loose. With the Transfer Roll
fully seated on it’s axle and the Print Drum properly
installed, pivot the Inking System Housing towards the
print drum until the surface of the Transfer Roll makes
positive contact with the Bearer rings on the Print Drum.
The contact pressure should be just enough to posi­tively drive the Transfer Roll when the Print Drum is
rotated. When the proper position has been reached,
tighten Screw “B” and then Screw “A”. Rotate the Print
Drum to ensure the Transfer Roll is rotating.

PIVOT SCREW “A”

ADJUST FOR
LIGHT CONTACT

ADJUSTING
SCREW “B”

In operation, when the Print Drum is rotating, the rubber
Bearer rings on the Print Drum must positively drive the
Transfer Roll. The amount of engagement pressure
exerted at the contact point between these two compo­nents is adjustable by moving the position of the Inking
System Housing. If the contact pressure is too light,
the Transfer Roll will not rotate and no ink transfer will
occur. If the cont act pressure is excessive, it will cause
too much drag on the Print Drum and the Index Mecha­nism will not operate properly .

5 - Install the screw and washer assembly and tighten fully,

then loosen the screw approximately 1/8 turn to allow
the slide to move.

Test the motion of the Index Slide by moving it back and
forth in the slot. It should move freely but must be held
securely in the slot by the washer and screw. If necessary,
