To apply and save the values, press the Apply button in the dialog box before closing it. The new settings are saved for that particular substrate type for the current and future prints. They are not applied to all substrate types. Optimize the preset for higher print speed Action Reduce the number of passes. Possible risks and compensations ● Risk: Poor curing performance. - Compensation 1: Reduce the ink density by one or two levels for each level that the number of passes is reduced. Example: For most front-lit materials, 6-pass 100% ink > 4-pass 80% ink > 3-pass 60% ink. - Compensation 2: Slightly increase the curing airflow to eliminate minor curing artifacts. - Compensation 3: Increase the curing temperature if you choose not to compensate with the ink density. NOTE: This is feasible only with substrates that do not show thermal deformation defects at higher temperatures. ● Risk: When you reduce the number of passes, especially to 4 or fewer, some artifacts such as grain, bleed, and coalescence may become visible. It is possible to compensate to some extent with the following settings: - Compensation 1: Reduce the ink density as described above. - Compensation 2: Increase the optimizer ink level in 2% steps for each level that the number of passes is reduced. Example: 6-pass 12% optimizer > 4-pass 14% optimizer. - Compensation 3: Increase the drying lamp power in 10% steps for each level that the number of passes is reduced. Example: 6-pass 50% power > 4-pass 60% power. Optimize for best print quality and/or widest gamut Actions ● ● ● Use a 6-color ink set. Increase the number of passes. Increase the ink density. Considerations ● A 6-color ink set enables smooth transitions; always use this option for best print quality. ● Use an 8-pass print mode for best print quality with frontlit substrates. 114 Chapter 4 Handle the substrate ENWW
