10 Troubleshoot print-quality issues
General advice
The HP Latex 3000 printer has been designed and qualified to the highest standards to provide the optimal
compromise between print quality and productivity. Prints for outdoor use can accommodate more visible
defects as they are viewed from a long distance. For shorter distances, as in indoor advertising, defects need
to be less visible. To decide whether a defect is considered acceptable, as a rule of thumb, the table below
shows the appropriate viewing distances.
Print mode m²/h ft²/h To view output at…
4 pass (outdoor) 98 1050 > 3 m
6 pass (indoor) 77 828 1–3 m
You are recommended to review the acceptability of a defect according to this table before proceeding to
diagnose it to make sure the selected print mode is the most appropriate for the purpose of the job.
Increasing the number of passes to 8 or more enables higher ink quantities if needed and/or the use of
difficult printing materials thanks to the longer drying and curing times. Print modes with more passes are
more resistant to banding. In general, follow these recommendations:
● Avoid touching the substrate while printing is in progress.
● Judge the print quality after the print has completely emerged from the printer. In some cases, defects
seen while printing disappear after the image is completely cured.
● Check that the environmental conditions (room temperature and humidity) are in the recommended
range. See
Environmental specifications on page 296 .
