Hi, Sorry, this is slightly off topic. I want to convert a pcb layout file which is in gerber format to PostScript to print on paper. Are there any ready made utilities, with the source code, in Public Domain available? What about GhostScript? BTW have you tried to make a layout mask using transparency, ink jet printer and photoresist, is the quality and contrast acceptable? I have tried using laser printer, but have found that the black areas were slightly transparent to UV, so the resulting pcb was practicaly unusable. I also had no lack using this special transparencies (TES or something else) which you iron press on a copper board. Thanks for comments, Janusz
