"Our preference would be to receive a locked-down file format, such as DCS, CT/LW or TIFF/IT-P1. That data may still need to be converted in our current process, but the ad's appearance is essentially locked down by the customer. Since PDF-X is only normalized information, essentially cleaned up PostScript, the file still must go through a RIPing process. Changes can occur at that point, and we have to accept the responsibility. It's a question of liability—who takes ownership of the digital ad, and what is that worth?"
