Specifies the settings for plot color merge control.
This information pertains only to raster plotters. For overlapping lines, merging two different color lines creates a third color. For example, merging a magenta line with a yellow line produces red where the lines intersect. Whatever line is received last by the plotter will cover any line it intersects.
Select your Merge control option by going to the Merge Control leaf of the Graphics branch of the Device and Document Settings page of the PC3 Editor.
