Toner Transfer is not an option for large quantity or quick production and in my area I could not find any photosensitive sprays.
I tried with screen printing emulsion, but it does not stick with the copper quite well after exposure. I tried also with plastic paint by screen printing process, but I couldn't achieve the resolution I wanted (12 mil trace with 12 mil clearance).
The plastic paints sticks with the copper quite well but it is not VU Curable. Does mixing the plastic paint with the emulsion will make any use to me?
If it still don't work I got a last option of this. But it is not available in low quantities. They provide a minimum of 20kg. But for my need 1kg will be enough.
What should I do?
