Problem: Excess White Foil
After Application Of White Over The Black Silk-Screen Layer, Excess White Is Left On The Board. How Do I Get Rid Of It?
- The WhiteTRF film is a relatively "thick" pigment to try to cover solid black toner. Because of this, surface tension over the copper board start to play a part in holding onto areas of white so that when the foil's carrier is peeled back, you wind up with lots of excess white.
The simplest method is to use Scotch "Temporary" tape available at any stationary store. It is marked in a predominantly blue package and is very inexpensive. Just lay down strips directly over all white areas and peel back 180º over itself. This will lift off any and all white pigment that should not be there without damaging the white fused to the black toner image.
