HP-GL/2 color differences in different HP DesignJet

Printers

Color differences between one image printed on the HP DesignJet

500/510/800 Series and the rest of the DesignJet platforms are due

to the different chemistry of the 500/510/800 series inks compared

with the rest of the inks for other printers. This color variability

among different HP DesignJet Series Printers has always been

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).

Banding at variable extreme environmental conditions

Since the Accuracy Calibration has been done at normal

environmental conditions, printing in extreme environmental

conditions will cause banding because the advance of the Drive

Roller does not correspond to the same conditions that the

calibration was done in. To solve the problem, try the following:

 Perform the Accuracy Calibration in the new environmental

conditions (Refer to the User’s Guide).
