TP 11 Colour Bands and Dithers Test Pages
These six A4 (8.5 x 11 inch) pages are a set of 6 diagnostic test prints used to diagnose image
quality issues related to colour uniformity. Figure 1 shows the test pages printed.
Colour bands and dithers test pages are printed from dC612.
NOTE: All test prints should be printed on A4 or 8.5 x 11 inch plain paper and long edge feed.
Use the best quality media available. Do not use hole punched paper. Failure to do this will
result in an error message being printed instead of the test page.
NOTE: When the paper selected for the test print pages is correct, the test pages will be
printed with annotations on the bottom edge confirming the test print name, LEF status and
that double chevrons will be printed if the paper used is A4. The chevrons indicate the stitch
position between print heads.
Purpose
These pages are used to evaluate print quality problems caused by drifting or mis-adjusted
print heads.
To solve image quality problems associated with colour uniformity, refer to IQ 13.
