Hi All,
I have been supplied a greyscale jpeg image that has to be used in a 2 colour print job. Even though the image is greyscale, when I move the Eyedropper over the image, the colour information is in CMYK (C=38 M=31 Y=31 K=0). Sure enough when I preview using Proof Setup, I’ve got information on the C, M, and Y plates but nothing on the K plate.
I have to prepare this image for a 2 colour print job so the C, M, and Y colour information must be converted to K (it doesn’t matter if the final grey is not the same shade as the original, as long as it’s grey). Unfortunately I can’t work out how to do this.
I’ve tried selecting the grey areas, creating an Alpha channel and filling with black but, of course, I loose the anti-aliasing around the edge of the image. So any other ideas will be gratefully appreciated.
Thanks in advance for your help.
Martin
