11 Troubleshoot print-quality issues General advice The HP Latex 3000 printer series 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.
