Scitex Continuous Tone Format (SCT)
The Scitex Continuous Tone file format was developed by Scitex and is used for high-end image processing. The SCT/CT files are used primarily to store CMY and CMYK color space for the image. For saving the SCT file format, LEADTOOLS ePrint Professional saves it as CMY instead of CMYK. This maintains the image quality, since the conversion from RGB to CMYK will result in some loss of data.
The default extensions used by this format are: SCT and CT.
