Absolute colour consistency between all printers within a production environment is critical if all prints are to exhibit precisely matching colours regardless of the printer on which they were printed. To achieve this, Epson submits each printer to an exhaustive colorimetric calibration process, checking and correcting the calibration using high precision spectrophotometers.
In using spectrophotometers, the light absorption/reflection levels of inks printed with each individual printer are measured against a predetermined value and, where necessary, the printers are recalibrated to ensure consistency with each colour. As a result, colour proofs, photographic prints and fineart prints from different printers of the same model remain totally consistent.
