Hello

 

I used negasilk.ulp for a while for inverted silkscreen, but I decided to enhance it a little and make it easier.

 

Steps:

 

1. First create your art work (Polygon in top layer with text inside it on layer 41 tRestrict with vector font type).

2. Run Ratsnest.

3. Name the polygon with "NEG_SILK" to make it special from other normal polygons.

 

With this enhancement there are no need to run any script file and also can help you to add negative silk screen within a design has already other polygons.
