Before printing CATP
Make sure the print quality meets the necessary technical specifications (for example, Color Adjust,
WH focus and skew, etc) before performing the CATP.
CATP requirements
1.
Verify that the following has been performed:
a.
Perform the Corner job adjustment.
b.
The Writing Head Skew (Image Skew) should be adjusted until the cross-hair sights
line up exactly within a small tolerance. Use the Skew Test job.
c.
Perform the Color Adjustment procedure.
d.
Perform the Image Placement procedure.
e.
Check the print quality and make sure that the PIPs do not generate any white spots.
However, maximum tolerance is four spots, maximal size 1 mm each, appearing on a
single page.
White spots that are less than 0.1 mm are negligible.
Some targets require
a
×
25 (or higher precision) eyeglass with an internal graticule.
Measurements of optical density and gray scales are done with a densitometer (X-
Rite 408).
For presses with less than seven colors, perform the test for the number of colors
installed.
If the print test quality is uncertain, compare it to the reference master CATP job.
