A CT file represents a bitmap image associated with Iris printers. This brand of large-format color inkjet printers was released in the 1980s and is currently owned by Kodak. Iris printers are used for prepress purposes, delivering a hard copy that shows exactly how the image will look like, and allowing users to check colors and design before mass production printing. They were used particularly in the 1980s and 1990s for reproductions of fine art on different types of media, but in recent years have been superseded by Epson printers.
