HP-GL/2 color differences in different HP DesignJet

Printers

Color differences between one image printed on the HP DesignJet

1000 Series and the rest of the DesignJet platforms are due to the

different chemistry of the 1000 series inks compared with the rest of

the inks for other printers. This color variability among different HP

DesignJet Series Printers has been always present. To solve the

problem, try the following:

Perform the color calibration from the driver at the time of

printing. However, that calibration is not very accurate but it may

help in the most severe cases.

Some applications have color controls for the user to modify the

image in order to obtain the desired colors.

Printing with PostScript reduces the problem significantly.

Avoid very long exposures to extreme environmental conditions

after printing with glossy media (more than 12 hours at 80%

humidity may result in severe changes in color).

Scratches on prints done on NTP, Vellum and HP High

Gloss media

Normally at the end of a roll, the curl on the media is high and the

printed area can touch the media load handles or the media roll,

transferring ink to the "still-not-printed" media or damaging the

actual print. This problem mainly affects Natural Tracing Paper

(NTP), Vellum and HP High Gloss Media. To solve the problem, try

the following:

Increase the Dry Time using the Front Panel (Refer to the User’s

Guide - Chapter 3 Working with Paper).

Install a new roll of media.
