Just installed a new IMac computer. I have two printers available. Canon MP470 connected via USB port and a HP Photosmart 6510 connected via WI-FI. When printing InDesign documents on the Canon printer all colors print a weak color (black is grey etc.). The same document printed on the HP Photosmart 6510 black prints as black and other colors appear normal as designed. Illustrator documents printed in black on both machines print black. Have I messed up a setting?
I have had the following Preferences set:
On Screen: Display all Blacks as Rich Black
Printing/Exporting: Output all Blacks as Rich Black
and have also checked to activate:
Overprint [Black] Swatch at 100%
all colors print a weak color (black is grey etc.)
I just noticed you said all the colors are off, so it's probably a color management/profile problem. What happens if you export the ID file as a PDF/X-4 pdf and print from Acrobat?
