Does anyone paint their PCBs before applying the silkscreen using toner transfer method?


If so what do you use? I assume you would need a high temp paint like engine paint?


I was thinking of painting while to make the silkscreen more readable with the black toner.


I sure wish you could get white toner in the stores.

It is one of my many pending experiments. I don't know if the clear acrylic Krylon will dissolve toner or not, I will let you know. Of course, I am talking about doing after the transfer, it sounds like you want to do it before.

If it works let us know.

I do - standard acrylic spraycans seem to be fine, but high temp would only be better of course.

I tried enamel spraycans of a few colors a while ago (see attached) but as i normally use a glass paint on the copper side as a solder resist, i also tried using that on the non solder side as well since it is high temp, water based, cheap, and comes in a variety of colours (including white but i just use green for both sides). It works well but for single sided boards, toner straight on the fibreglass is quite high contrast (see pix)
