PDF images of a PCB, to size, spot on. The black is the traces, mirrored. But when I, or a pro print shop, print to clear film or heavy tracing paper the image of the traces is not a dense black. If I do a Print Screen of the page 4 of the files that I want to use, and open in Windows Paint, and then draw a black line across a blown up pad, it seems obvious to me that the PDF is not true dead black.

See http://www.gatesgarth.com/not-dead-black.png

Can it be altered in something like GIMP of Photoshop to make all traces dead black without losing any edge definition of the traces and keeping the images the exact same size?


As say, page 4 is the only one of relevance to my needs, thanks.

Hi TheAlex and Chaos, thanks for the replies, yes it's to make replacements for three tired PCB's in an obsolete power supply. I will try the adjustment TheAlex talks of. I have the film Chaos mentions, but on this the image is also from from opaque, I am convinced it's a facet of the PDF images as I have not had this issue before, using other images that appear dead black. Thanks.

Thanks to all, the conversions are excellent and a big improvement can be seen in the printed quality, the density increase is very apparent. Your time and trouble is much appreciated, thanks again!
