A PROOF PRINTING ADJUSTMENT SYSTEM AND METHOD

摘要

A printing system comprises a printer and firmware. A spectrophotometer is integrated with the printer. The firmware includes color adjustment tables or algorithms. The proof printing system adjusts the output signal of the spectrophotometer to compensate for conditions at the time of printing or spectrophotometric measurement. The system is also capable of predicting the time it takes a color patch to reach a predetermined degree of drying that will allow reliable spectrophotometric measurements to be made. Compensates include drying of the ink, based on the determination of humidity and temperature. Measurement compensates also include use of different backing colors behind the proof and the presence or absence of an ultraviolet cutoff filter. The system can also adjust the output signal of the spectrophotometer based on a reference color standard.
