Lee, I tried that and it honestly had a negligible effect on the output.
What has been happening is say there are three wires parallel to each other spaced about a 1/2" inch apart two out of the three print via the PDF one thickness and the third prints with a thinner thickness. All three are on the same layer and have a single line weight set for them.
A work around we came up with is to setup a CTB file where we had to change the line weights on individual colors and essentially had to double the line weight to make them look decent and get them to look relatively the same.
Does anyone know of something other than that to resolve this issue? At this point we are not in favor of having to modify pen color line weights since all it takes is one person to make a new layer with say red which we currently have set to 1.2mm and we don't want that geometry on that layer printed that thick.
Thanks,
Brian
