HP DESIGNJET L26500 Series - Summary of Common Printing Problems

A Summary of common printing problems
This is a table of common problems and the RIP parameters that can be changed in order to solve the
problem. Some possible side-effects are also shown. For a more detailed treatment of any particular
problem, please see the relevant chapter in this guide.
Problem Parameter Change Possible side-effects
Durability problems, ink smudges or
oily finish
Curing temperature Increase Substrate jam, substrate damage,
ink smears
Number of passes Increase Slower printing
Substrate jam, substrate damage,
ink smears
Curing temperature Decrease Less durability (smudges), oily finish
Vacuum (and disable cutter) Increase Substrate skew
Top and/or bottom margins Increase Substrate waste
Drying temperature Decrease Coalescence, banding, less
durability (smudges), oily finish
Horizontal or thin vertical banding
in saturated area fills
Drying temperature Increase Substrate jam, substrate damage,
ink smears
Ink limits Decrease
(depends on RIP)
Reduced color gamut
Number of passes Increase Slower printing
Modify color separations and dark
color generation
Graininess, color misregistration or
lack of sharpness
Align printheads
Calibrate substrate advance
Black areas look hazy or image
gloss is not uniform
Modify color separations and dark
color generation
Drying temperature Increase Substrate jam, substrate damage,
ink smears
Number of passes Increase Slower printing
Curing temperature Decrease Less durability (smudges), oily finish
