Substrate Family
Description
Self Adhesive Vinyl
PVC films with adhesive on one side. There can be white finished or transparent. The liner can be paper
or plastic based.
There are 2 main manufacturing processes: calendering and casting.
Banner
Usually a polyester mesh (or fabric) covered with PVC coating. There are also recyclable types to cover
the same applications (green banners). Banners can be frontlit or backlit.
HP Photorealistic
Paper based (cellulose) media with coating (gloss and matte finishing). It has a weight higher than the
other billboard and offset medias (200gsm or higher). The main difference is its rigidity compared to the
other billboard medias.
Paper - Solvent
Paper based (cellulose) medias with coating to allow their use in solvent printers. Also they usually have
a limited water resistant performance.
Paper - Aqueous
Paper based (cellulose) media with or without coating or offset paper. The main difference with the bill
-
boards is that this papers are not compatible with solvent printers. Weight usually around the 100gsm
Mesh
Usually a polyester mesh covered with PVC coating with holes. Some of these media types can have
a liner and be self adhesive.
Fabric
Fabric medias are usually composed of polyester fibers.
Some of the fabric media types come with a liner to avoid the ink trespassing the media. Fabric materi
-
als which are very stiff (such as polyester canvases) are preferably loaded as “banner”.
Film
Usually a polyester film (although there are other materials like PVC, PC...) for backlit applications.
They are typically translucent although there are transparent versions.
Create and name a new substrate profile in RIP by:
0.
Check substrate profile availability in RIP and/or media vendor web site
1.
If not availbale, choose the substrate family to start from “substrate families” table below
2.
Create a copy or use the substrate family
3.
Select a name for the new substrate in case you create a copy
Proceed to section
“Printer calibration”,
subsections color
calibration” and
“color profiles” in
“Maintenance and
troubleshooting guide”
Yes
No
Table 2
Checking the quantity of ink on the substrate
Check if the ink quantities in your profile are adequate. Look at the
plot color patches and check if one or more of the patches have
the right ink quantity using the guidelines below:
Too much ink quantity
The patch shows one or more of the following problems:
The last two or
three scales of
the plot look the
same.
If your profile has too much ink quantity
•
You might have chosen a substrate profile which uses exces
-
sive ink versus the one your substrate allows. Consult the media
vendor web site and hp web site for the latest substrate profiles
and information
Consult your RIP documentation to make sure you’re applying
the right substrate Icc profile
Consult your RIP documentation on how to lower the total ink
quantity of the profile
NOTE:
Backlit and some fabrics substrates usually require to
be used with the “High Ink Limit” option enabled in the RIP.
Too little ink quantity
•
The whole plot looks washed out:
Vertical
bands
Horizontal
bands
The last scales of the plot
show a smooth increase
Coalescence
grain
Correct ink quantity
•
The patch has no defects
and
•
Increasing amounts of ink result on increasing color density.
