Hi, I have some B/W photos that are going to be printed digitally on big outdoor banners. I want them to be in Rich Black. If I just convert the Grayscale image to CMYK, 100% Black becomes C=75, M=68, Y=67, K=90. It looks OK on the screen but rich black in CMYK is usually like C=40, M=30, Y=30, K=100. Is there a more pro way of converting the photos? Any thoughts? Thanks so much.
