Hi everyone, I'm having a bit of trouble matching blacks. I have downloaded some stock images where the background is a standard RGB 0 0 0 . When I place this image into InDesign to produce some print work, I've created a palette of C 75 M 68 Y67 K90 which is shown as the equivalent of RGB 000 in the color picker. When I render this as a PDF though the blacks do not match. After playing about for a while the one palette I found that appears to match is Registration, though I've been told never to use this. Does anyone know the best solution to match blacks when using RGB images such as in this example? Any help is much appreciated! Many thanks!
