A Full Plate

According to Nilpeter Digital Service Engineer Soren Ringbo, the DI-3300 uses 16 laser diodes to image Presstek PEARLwet plates for printing with dampeners, or PEARLdry plates for waterless printing. PEARLwet plates feature an aluminum base and a water-loving top layer which is heated and loosened during the imaging process. The released upper layer is then cleaned off with a solution that is 90 percent water, 10 percent Varn Total.
