Select the desired material in the "Material" field on the right. Then assign the colors according to the different material effects.
As in JobControl®, only one parent parameter can be used per plate in Ruby. However, the material effects can be used to define multiple processes, such as different resolutions, screens and speeds per color.
In Ruby, there is no extra photo-optimized process mode. The laser software recognizes photos automatically, so only the desired dithering (raster) has to be selected. This is done directly in the material effect.
