The 5-Color ink set found in the imagePROGRAF iPF780 printer is ideal for technical applications. This ink technology utilizes four highly colorfast dye inks for producing bold, expressive color, plus a channel of pigment matte black ink for printing precise lines, smooth curves and small text on technical and office documents. Also included is a newly formulated magenta ink that helps produce a wider color gamut in the red and orange spectrums, compared to previous models. These Canon inks provide superb adhesion to media, scratch and marker resistance and help ensure minimal "bleeding" between colors and text. Even small text printed on colored backgrounds or on uncoated technical papers is crisp and legible.
