Until recently, I have been able to make PCB's from presensitized boards at close to 100% success rate because I ordered my designs on transparencies produced by a printing shop.
Today, the print shop I relied on no longer prints on transparencies. I searched for other places, and the only two local ones I come across that could possibly do it but at high prices are "Crush Media" and Staples copy and print (both have their pitfalls) but with the way supply shortages are going, who knows how much longer they can support transparency printing.
So let's assume transparency printing is no longer an option.
I do have a printer at home but it's not capable of printing sharp black images. It can do greyscale but the images sometimes have dots or the printer sometimes prints bleed marks, both which are NOT good for PCB development.
What someone suggested (I think it was from Mike's PCB website which is no longer accessible) is that vellum paper may work. I had limited success with that but I had to print 2 copies of the image and tape them together and if the alignment is not perfect, then my circuit will be messed up.
So what am I to do? I still have pieces of positive presensitized PCB and I want to eventually make nice circuits out of them.
