The specially formulated LUCIA PGI-72 Ink produces professional quality photo prints and superior longevity, perfect for displaying your printed works of art. Canon's proprietary FINE (Full Photolithographic Inkjet Nozzle Engineering) technology delivers exceptional sharpness and detail. For the best printing results, always use genuine Canon ink and photo paper. Plus, Canon's individual ink system can help increase efficiency by reducing waste and saving you money since you'll only be replacing the color that runs out. The PGI-72CO Chroma Optimizer for the PIXMA PRO-10 Professional Inkjet Printer is a critical element to attaining professional print quality with accurate color and reduced metamerism, on coated papers. The Chroma Optimizer reduces the difference in ink droplet height to form a flat and smooth ink layer. The result is evenly reflected light, deep blacks, and bright, saturated colors.
