I recently made a boo-boo. I sent a printer that usually receives documents prepared using SWOP a poster prepared using GRACOL.
The print part was managed by my client, not by me, so I could not see a proof. When I saw the final result I was devastated. Everything was very dark. The ink was cranked up to the point that mid values turned almost black. The print included photographs so they became very ugly. It was a CMYK print on coated stock but it almost looked like a B/W print on newsprint with a crazy 40% dot gain.
Now, I know I should have set the document as SWOP and not as GRACOL and that was my fault. I was wondering, though, if the difference should be so dramatic.
Is this a common result? If you print a GRACOL thinking it was SWOP, does everything look darker? Or was the print job just badly done with inks cranked up to absurd limits by the printer.
