The Canon PFI-300 Ten Color Ink Pack features a full set of specially formulated LUCIA PRO inks, designed to be used with the Canon imagePROGRAF PRO-300 printer. The ink produces professional quality photos with an expanded color gamut and enhanced black density. The included Matte Black ink provides deeper black levels on fine art paper as well as a wider dark area reproduction range with improved gradation. The Chroma Optimizer reduces the difference in ink droplet height to form a flat, smooth ink layer. This leads to an evenly reflected light, deep blacks, and bright, saturated colors on coated papers.
