Solving Image-Quality Problems
NOTE:To achieve the best performance from your printer, only use genuine HP
accessories and supplies, whose reliability and performance have been thoroughly
tested to give trouble-free performance and Photo-quality prints. For details of HP
media, see page 3-4, Supported Media Types and the Media Guide for the HP
DesignJet CP Printers supplied with the printer.
How to Proceed with the Image Quality Print Diagnosis
Solving image quality problems with the UV Pigmented ink is exactly the same as
with the Imaging ink. Whenever you suspect that your printing is not correct, it is
advisable to perform the Image Quality Test.
Please note that the UV Pigmented ink produces sharp images but not photo-quality
as it has different characteristics to the Imaging ink. This is because the UV
Pigmented ink is designed for enhanced indoor and outdoor lightfastness, and not
photo-quality imaging.
You can expect to see the following differences:
n A print produced with UV Pigmented ink will have a slight matte appearance
compared to one produced with Imaging ink, which has a brighter glossy
appearance.
n The volume and density of ink used to produce a print with UV Pigmented ink is
different compared to Imaging ink. This print quality may sometimes have
“speckling” (a very slight graining effect) which is a normal characteristic of the
UV Pigmented ink.
n You may sometimes see minuscule patterns in the print, which can be mistakenly
construed as banding. This is a normal characteristic of the UV Pigmented ink
and is caused by the placement and density of the ink on the media.
As HP has not tested non-endorsed media, the appearance of a print may differ to
one produced on endorsed media. Therefore it can only be used as an indication of a
possible print problem. It is recommended that you change to an endorsed media to
confirm a problem.
