3. Too little ink: The whole chart looks washed out. Try increasing the amount of ink in your RIP software, then reprint the chart and check again. You may have chosen a media preset that uses less ink than your substrate allows. Consult your RIP documentation to make sure you’re applying the right ...

In outline, the process consists of the following steps. 1. A calibration test chart is printed. 2. The HP Embedded Spectrophotometer (or, if you prefer, a different spectrophotometer) scans and measures the test chart. 3. The RIP uses the measurements to calculate the necessary correction factors f...

Color reproduction tricks Latex inks are a new technology, and there are some important guidelines when doing color separations (such as when creating or modifying a new media preset within your RIP) that will help to optimize the printer output in terms of color gamut, ink usage and print quality. ...

6 Troubleshoot print-quality issues General printing advice Use the following approach when you have any print-quality problem: ● Make sure that the substrate type that you select on the front panel, and in your RIP software, is the same as the substrate type that is loaded in the printer. Make sure...

Interpret the printhead status plot The print consists of small dashes, one for each nozzle on each printhead. For each individual colored pattern, make sure that most of the dashes are present. Corrective action 1. Clean any faulty printheads. See Clean the printheads on page 73 . Then reprint the ...

If you see this kind of problem: ● Ensure that the vertical correction option is disabled in the RIP and in the front panel. At the frontpanel, select the icon, then select Image quality maintenance > Disable vertical correct. (if this option is available). ● The printheads may be misaligned. Thi...

● If bands affect only some colors, the cause could be a defective printhead. ◦ Print the printhead status plot (see Use the printhead status plot on page 54 ). If necessary, clean the printheads (see Clean (recover) the printheads on page 18 ). ◦ Clean the printheads again. ◦ Align the printheads (...

Substrate advance adjustment on the fly If you are using no more than six passes, you can fine-tune the substrate advance while printing: selectthe icon, then select Image quality maintenance > Substrate advance calibration > Adjust substrate advance . Select a value of change from –10 mm/m to...

◦ If applicable, tell the RIP to group jobs together, so that printer temperatures remain more stable between jobs. ◦ Modify your media preset as suggested in Color reproduction tricks on page 53 . ● Irregular or isolated vertical bands ◦ Increase the vacuum level in steps of 10 mmH 2 O. Do not exce...

If you notice such a problem, there are various possible solutions. ● At the front panel, select the icon, then select Image quality maintenance > Enable color variation correction . This correction will then remain enabled until you disable it. ● If you notice the variation in intensity near one...

Ink smears Ink smears may be seen on the print for the following reasons. ● The substrate is skewed.

If some substrate continues to cause an obstruction within the printer, it can often be cleared by loading a rigid substrate type into the printer. 14. If you find that you have print-quality problems after a jam, try r...

This deformation may be particularly noticeable in the following applications. ● Printing images that will later be cut automatically or manually. When there is bow deformation, cutters that are aligned on the sides may lose alignment in the center. ● Poster printing, if the poster is framed or moun...

If the problem remains after removing the substrate jam, unload the take-up reel from the front panel and load it again. Take-up reel does not wind Predictably, if the take-up reel is not winding as anticipated, the printed output is likely to end up on the floor. If the printer recognizes a problem...
