IRIS CMYK Front End Processor CT

IRIS CMYK Front End Processor CT is a raster graphic file format used in IRIS Front End Processors, circa 1990. This is obsolete specialized hardware, and not very much information about the format is accessible, though some old manuals for the hardware are online. Apparently XnView supports it.
