The Scitex Continuous Tone (CT) format is used for high-end image processing on Scitex computers. Scitex CT files often come from Scitex scanners, which produce high-quality scans for commercial printing. The Scitex CT format supports CMYK, RGB, and grayscale files, but does not support alpha channels. Contact Scitex to obtain utilities for transferring files saved in the Scitex CT format to a Scitex system.
