DuPont™ Cromalin® blue-series is the first and only drop-ondemand inkjet proofer that can automatically keep itself calibrated. A robotic calibration module on the inkjet’s printhead includes a specially configured Gretag "Eye-One®" spectrodensitmeter that feeds data to the DuPont™ Cromanet™ proof server. As a proof is printed, the calibration module verifies that the printer is operating at a consistent and known level of performance so that the ink and media profiles used to create the proof will remain accurate. This automated calibration eliminates some of the variables that can be caused by manual calibration, such as speed, pressure, and human error. Proofs are printed on DuPont standardized proofing media that are automatically fed into the printer and imaged on a rotating drum. To provide consistent ink spots and even gray balance with minimal electronic interlacing, the proofs are built up line by line at an optical resolution of 1500 dpi. The Cromalin® blue-series package includes a dedicated Windows®-based proof server, the blue-series proof engine, the Cromanet™ RIP, and DuPont™ proofing inks and media. It also supports industry standards such as ICC, PostScript 3 (with an Adobe® PostScript 3 interpreter), PDFX3,SWOP, FIRST, and GraCOL.
