摘要: Density calibration for a printer is achieved using standard grey scale vignette master and stored gray image that the operator can invoke from panel of printer. The provides pre-calibrated used in conjunction with □standard□ to determine proper optical density. density then set by control based upon value obtained visually matching two vignettes.
