Abstract

A colorimeter for measuring transmitted, reflected, emitted and incident light comprises a pod that is demountably attached to a base and that contains a color-responsive detector and associated processing electronics. The detector mates with one of several detachable heads that are selectable to establish precise measuring conditions for the various measurements to be made. The colorimeter enables common and consistent calibration across all elements of the pre-press industry, from checking color proofs or color transparencies, to calibrating video color monitors.
