I get a lot of images sent to me as jpegs with a request to add certain pantone references to the image. Does any one know the best way to do this, as the images are then sent to a commercial printer for printing.
You don’t use Jpegs for printing either.
What exactly are you trying to do??
add a spot color??
Make an accurate selection of the area that needs to be the PMS color.
Press the delete key to delete it from the CMYK (assuming you have default foreground background color- if not press "d" first).
With the selection still active, add a spot channel in the appropriate ink.
Trap.
Save as DSC2 or PSD (or PDF?).
The images are usually sent to me as jpegs, because they do not have them as an eps or in a layer format. We have them printed on various things, leaflets, camera wraps, business cards, brochures etc. Which is sent to a commercial printer sometimes digital or lytho.
