Other applications
●Airport light boxes: Continuously lit from inside the box. Size varies from medium to very large images. Directional and advertising content.
●Bus shelters: Inside light box, visible by day and night. Changed very often (e.g. every week).
●Street signs: Various materials from blue back paper for billboards through light boxes and rigid boards. Some are fixed for medium periods and some changed very often.
●Billboards: Very large boards covered with tiles of images, long viewing distance and low picture resolution but vivid colors. Lately changing from tiles to banners of vinyl or polyethylene.
●Interior decoration: Walls covered with graphics to create a unique atmosphere. Usually printed on blue back paper and mounted directly on walls or rigid boards. May also be printed on vinyl or fabric.
●Building wrap: Part of a building covered with vinyl or mesh substrate, which is stretched and mounted on a frame. It is often necessary to weld or sew strips of substrate together.
●Art: Very high quality images printed on canvas or other flexible or rigid substrates.
●Directional signs: Short or long term signs, usually on rigid boards.
●OEM: Decals of names or graphics associated with the equipment. Used for home and garden equipment, appliances, vehicles, vending machines, ATM, light and heavy machinery, etc.
●Flags: Banners of fabric and textile that hang down or are mounted on poles. Used indoors and outdoors. Also used as balloons of different shapes.

NOTE: The printer does not support substrates narrower than 914 mm (36 in).
NOTE: Porous substrates require the use of the ink collector kit.
NOTE: The fabric specifications supported are the following: Grammage > 100 g/m²; Fabrics "mesh" style with Porosity/Open areas < 20%; "Mesh Substrates" with Porosity/Open areas < 20%; Elasticity < 5%. For best results, print textile applications on fabric that does not stretch. Performance may vary depending on the substrate. Please consult your substrate supplier for compatibility details.
Substrate tips
General tips
Handle unprinted and printed substrates with care, and preferably with cotton gloves, to avoid fingerprints. For heavy rolls, use a forklift, and two people wearing security shoes.
Before loading a roll:
●Check that temperature and humidity in the room are within the recommended ranges for the printer. See Environmental specifications on page 104.
●Check that neither the roll nor its core are bent or deformed, which may cause the substrate to jam in the printer.
●If the roll has been stored in a place not offering the recommended environmental conditions, allow some time for it to adapt to the temperature and humidity of the printer's environment.
Handle the substrate
ENWW |
Substrate tips 21 |
● Check which is the correct side for printing, by reading the label inside the core or the note
|
|
inserted into the package (or see Tips for specific substrates on page 23). |
|
● Check that the substrate is correctly attached to the input core. Otherwise, you will see poor print |
|
|
|
quality due to substrate advance errors. |
|
● You may find it easier to load a roll if you first move the carriage beam to its highest position. |
|
|
While loading a roll, make sure the leading edge is parallel and straight across the output core, and |
|
|
attached evenly (start taping the substrate to the core at the center, then move towards the edges). |
|
|
After you have loaded a roll: |
|
|
● Make sure that the edge holders are set on both sides of the roll. Do not use any other Edge |
|
|
|
holder from another printer, only use the edge holders that came with the printer. An incorrectly |
|
|
loaded roll may cause waves or cockles in the substrate, leading to ink smearing and printhead |
|
|
crashes. |
|
● Check the correct carriage beam position for printing: high for thick substrates, normal for others. |
|
|
|
See Set the carriage beam position on page 25. |
|
● Check that you are using the correct substrate preset in the HP Internal Print Server and the correct |
|
|
|
ICC profile and other settings in the RIP. |
Handle |
|
|
● HP substrates are optimized to provide the best out-of-the-box printing experience with your |
||
|
printer. However, you may want to modify the ink limits or the number of passes; in which case, |
|
|
temperature, vacuum or tensions may need to be adjusted. You can create a new substrate preset |
|
the |
|
from the default preset you are using and make your changes. |
|
|
|
substrate |
● Use the HP Internal Print Server to check that any required calibrations have been done: color |
|
● |
For the best print quality, the substrate should stay flat and unwrinkled in the printing zone, the |
|
|
|
calibration, substrate-advance compensation, printhead alignment. See the Maintenance and |
|
|
troubleshooting guide. |
|
|
substrate advance should be constant and the substrate should move straight. |
|
|
|
● Do not cut off pieces of substrate while the substrate is loaded into the printer. This may cause the remaining substrate to jam.
After printing, try to allow 24 hours before stacking, folding or rolling printed substrates.
NOTE: Printing on porous substrates may result in visible vapor being generated from the waterbased ink.
You can find further information on the Web:
●The specifications, finishing, processing and warranty information for each individual HP substrate are available from http://www.hp.com/go/designjet/supplies/latex/.
●HP Image Permanence information is available from http://www.hp.com/go/supplies/ printpermanence/.
●HP offers recyclable substrates such as HP HDPE Reinforced Banner, HP Wrinkle-free Flag with liner, HP Heavy Textile Banner, HP Photo-realistic Poster Paper and HP DuPont™ Tyvek® Banner.

Substrate configurations
The substrate can be loaded in a variety of different configurations to suit your different needs. Before loading, you must go to the HP Internal Print Server and select Substrate > Load/Unload, then select the configuration you intend to use.
The basic configurations are illustrated below. These configurations can be used for single-roll or dualroll printing, and for porous or non-porous substrates. Porous substrates require the use of the ink collector kit: see The ink collector kit (LX850 only) on page 28.
●The roll-to-roll configuration is suitable when you intend to print a whole roll without cutting it until the input roll is empty. The substrate cannot be cut in mid-roll unless printing double-sided, and then it must be reloaded afterwards.
●The roll-to-free-fall configuration (LX850 only) is suitable when you want to cut and remove each print as soon as it comes out of the printer. The substrate is kept under tension between the input roll and the tension roller; but it can be cut after the tension roller because then it is no longer under tension.
24 Chapter 3 Handle the substrate |
ENWW |
●The roll-to-free-fall with collector configuration (LX850 only) is suitable when you may want to cut the substrate and remove the output roll before the input roll is empty. The substrate is kept under tension between the input roll and the tension roller; but it can be cut after the tension roller because then it is no longer under tension.
Set the carriage beam position
The carriage beam position determines the vertical distance between the printheads and the platen. If it is too great, print quality will be impaired. If it is too small, there is a risk that the printheads will come into contact with the substrate, causing smears or damage.
To set the carriage beam position, go to the front panel and select the Substrate menu |
, then |
Substrate management, and press OK. Select Carriage beam position. You can choose the highest position, a custom position or the normal position.
●The highest position is not used for printing: it may be used for loading substrate or for maintenance tasks.
●A custom position is used for thick substrates, or for substrates that wrinkle slightly due to heating.
TIP: Try to avoid wrinkling by using substrates that do not wrinkle, or by using a slower print 
mode that will allow you to lower the drying temperature.
We recommend setting the custom position to the thickness of the substrate plus two or three millimeters. The current setting is indicated in the front panel by a √ mark.
●The normal position is suitable for unwrinkled substrates up to 0.7 mm (0.03 in) thick.
WARNING! Keep away from the printer's moving parts until the carriage beam has reached its new position.

NOTE: LX850 only: If you have installed the ink collector kit, the normal position and the lowest custom position are automatically adjusted to take account of that.

The following steps that must be followed before the printer can print:
1.Ensure that the ink collector kit is installed for porous substrates, and not installed for non-porous substrates. See The ink collector kit (LX850 only) on page 28.
2.Start the printer. See Turn the printer on and off on page 12.
3.Go to the HP Internal Print Server and select Substrate > Load/Unload to open the Printer Configuration window.
4.Select the printer configuration that you intend to use, and press Next to see the on-screen help.

NOTE: The Skip Substrate load check box should be checked only if the printer has just previously had the same configuration (i.e. the same substrate, same profile), and because of a severe system error, you had to restart the printer.
5.Load the substrate. Substrate loading instructions are displayed in the HP Internal Print Server window. For more detailed instructions, see Load a roll onto the spindle on page 33 and Load a roll into the printer on page 38.
6.Press the Load button in the HP Internal Print Server to start the substrate check, then enter the substrate type in the Loaded Substrate window.
TIP: If the printer has been idle overnight with substrate loaded, and exposed to high or low 
temperatures, advance the substrate 13 to 25 cm (5 to 10 in) before printing, to avoid printhead crashes or ink smears on the substrate.
