Other settings that can affect length consistency: - Temperature: The higher the temperature, the more the substrate tends to deform. If you observe substrate deformation after printing, lowering the temperature can help to reduce the deformation. - Vacuum: High levels of vacuum can help to control the substrate in the print zone, but when the level is too high it can also affect the substrate advance. Therefore reducing the vacuum can help to improve length consistency. Take into account that, when the take-up reel is used, less vacuum is needed. ● In bidirectional printing, minor differences in tone may be noticed on close inspection This happens because the drying times are not the same across the scan axis. Adding a small inter-pass delay offset of about 0.5-1 second may give better results. 124 Chapter 5 Troubleshoot print-quality issues ENWW
