4 Handle the substrate

Overview

You can print on a wide variety of printing materials, all of which are referred to in this guide as substrates.

Use substrate

Choosing the correct substrate for your needs is an essential step in ensuring good print quality. For

best printing results, use only recommended HP substrates (see

Supported substrate families

on page 16), which have been developed and thoroughly tested to ensure reliable performance. All

printing components (printer, ink system, and substrate) have been designed to work together to offer

trouble-free operation and ensure optimal print quality.

Here are some additional tips about substrate usage:

●

Allow all substrates to adapt to room conditions, out of the packaging, for 24 hours before using

them for printing.

●

Handle film and photo substrates by the edges, or wear cotton gloves. Skin oils can be transferred

to the substrate, leaving fingerprint marks.

●

Keep the substrate tightly wound on the roll throughout the loading and unloading procedures. To

make sure that the roll stays tightly wound, consider using tape to stick the leading edge of the roll

to the core just before removing the roll from the printer. You can keep the roll taped during storage.

If the roll starts to unwind, it can become difficult to handle.

NOTE: The use of tape to stick the leading edge of the roll to the core is especially important for

heavy substrates, because the inherent stiffness of the substrate can cause it to loosen and unwind

from the core.

●

Whenever you load a roll, the front panel prompts you to specify the substrate family that you are

loading. For good print quality, it is essential to specify this correctly. Check that the substrate

belongs to the family named on the front panel, and check also that it matches the substrate profile

in the RIP.

●

Print quality could be impaired if you use a substrate that is unsuitable for your image.

●

Make sure that the appropriate print-quality setting is selected in the RIP.

●

If the substrate family shown on the front panel does not correspond to the substrate that you intend

to use, take one of the following actions:

◦

Reload the roll into the printer and select the correct substrate family. See

Unload a roll from

the printer on page 25 and Load a roll into the printer (automatically) on page 19.

◦

At the printer's front panel, select the

icon, and then select View loaded substrate >

Change loaded substrate.

NOTE: Substrate advance calibration is not performed when the substrate family is changed

from the front panel.
