I have a problem with a B/W photo.
Hello everyone, I need to print a black and white image on a glass, I scanned a black and white photographic film. I have a file in CMKY in high resolution, I have already done some tests on glass printing with bad results because in black you can see the colored pixels, since every print test has a high cost, some of you would help me to solve permanently this problem ? I would need a digital image made only from black just like the photographic negative, the white areas would be transparent, ie get the channel of the first black of colors. Thank you all.
