Troubleshooting

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:

nPerform 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.

nSome applications have color controls for the user to modify the image in order to obtain the desired colors.

nPrinting with PostScript reduces the problem significantly.

nAvoid 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:

nIncrease the Dry Time using the Front Panel (Refer to the User’s Guide - Chapter 3 Working with Paper).

nInstall a new roll of media.
