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 media preset, and to find out how to increase the total ink limits of the media preset. For a quick solution, you could change to a different media preset that uses more ink: for example, self-adhesive presets use more ink than paper-aqueous presets. NOTE: Backlit and some textile substrates usually need to be used with the "High Ink Limit" option enabled in the RIP. Faster printing The obvious way to increase speed is to reduce the number of print passes, although this will tend to reduce print quality. Bear in mind the following considerations. ● With fewer than 10 passes, you may see an increase in grain. ● With fewer than 8 passes, the printer is more sensitive to substrate advance problems. ● With fewer than 8 passes, you may need to reduce the ink quantity to improve print quality. ● If you want to use the high ink level option, you must use at least 10 passes. ● As you reduce the number of passes, the best curing temperature may be more difficult to find, and may be more sensitive to the ambient temperature and humidity. Here are some other suggestions for increasing the speed of printing. ● Concatenating prints saves time, because one can be sent while another is being printed. ● Disable the cutter: select the icon, then select Substrate handling options > Enable cutter > Off. With most substrates, this saves some time at the end of the printing process. ● Increase the cool-down curing temperatures. This also saves some time at the end of the printing process, but may cause slight substrate deformation, depending on the substrate. See also The printer seems slow on page 77. Color calibration The purpose of color calibration is to produce consistent colors with the specific printheads, inks and substrate that you are using, and in your particular environmental conditions. After color calibration, you can expect to get identical prints from your printer on different occasions. Color calibration can be launched from your RIP software; see your RIP documentation for details. ENWW Faster printing 51 Substrate settings
