Printing masks The concept of printing masks refers to the relative positions of the ink drops on the substrate. The mask uses a randomization algorithm to avoid visual patterns, and the result is a visually smooth surface, with minimal graininess, and no banding. Inaccurate alignment or substrate advance can interfere with the algorithm, causing different grain patterns along long jobs. On tiling applications, differences between panels can lead to visible seams. The new Uniformity mask is more robust against this kind of phenomenon, delivering a uniformly textured look in long runs, and enabling seamless tiling applications even when using Dual-roll. This is why the Uniformity mask is recommended for applications such as wall-covering, or vehicle wrapping; while the Large mask is recommended for applications such as posters, roll-up banners, or backlit signs The following images show the performance of the two types of masks when the substrate does not advance uniformly. Large mask Uniformity mask How to select mask type 1. You can select the desired mask by creating the corresponding print mode on the Edit Substrate menu. Remember that generic substrate presets must be cloned before being edited. 2. Provide a name to the print mode with Uniformity mask to make it accessible for printing. 112 Chapter 4 Handle the substrate ENWW
