Can I run sheets with metallic inks through a laser printer?
Always ask your clients how they intend to use a printed piece. Even if letterheads and other printed pieces have dried for more than the recommended 72 hours, the heat of the laser printer can reactivate the metallic ink and easily cause streaking on the sheet as well as on the rollers. Your ink manufacturer can provide you with metallic inks that are less heat-sensitive and will run through desktop printers with no problems. You might have to special-order those inks, so allow for extra time.
