The imagePROGRAF iPF6400S, 24-inch large format printer was designed for professionals in the commercial photography, signage display, reprographic and proofing markets that seek the highest possible standards for quality-control and image reproduction, while maximizing productivity. A large color spectrum is produced by the 8-Color LUCIA EX pigment ink set, which also provides scratch resistance and smoother gradations. The enhanced Multi-sensor allows for the printer to calibrate back to factory settings, and is included with this printer to help provide improved color density detection. A Color Calibration Management System allows for color calibration targets to be created using the iPF6400S printer with optional spectrophotometer and shared across all new iPFX400S 8-Color printers, while the included software allows for all printers on the network to be monitored from one central location. The printer supports ink tank sizes of 130ml and for the first time, 300ml, and the new Sub-ink tank system keeps some ink in reserve to allow for tanks to be changed without interrupting a print. The iPF6400S printer is also equipped with a 250GB hard drive, geared to help increase productivity in high volume printing and streamlined workflows, while allowing for fast processing of large files as well as the ability to reprint jobs directly from the printer.
