Preserve the surface quality your prints were built to deliver. Canon Chroma Optimizer for the imagePROGRAF PRO-300 helps even out gloss across the page, reducing the visual impact of bronzing and metamerism on high-end photo output. For studios, labs, and photographers who print work for presentation or sale, that consistency matters as much as color accuracy. Built as an OEM supply for the imagePROGRAF PRO-300, this ink tank fits the printer’s output system with the precision Canon specifies for professional media handling. It is intended for users who need repeatable results on glossy and semi-gloss papers, where surface uniformity can separate a polished print from one that looks uneven under light. When output quality is part of the deliverable, consumables are not interchangeable. Chroma Optimizer supports the finishing step that cheaper alternatives often ignore: controlling how light reflects from the print surface. That makes it a practical choice for photographers, proofing environments, and production teams that need every print to look intentional, not merely printed.
