The Canon Chroma Optimiser clear ink delivers even glossiness, expands colour gamut and makes black colours deeper. This clear ink is applied on top of pigmented inks for a smoother finish. Printing with Chroma Optimiser reduces the diffuse reflection of light, in turn producing original colours on prints. Achieve uniform gloss on the surface when printing on glossy or semi-gloss paper for a more even and smoother finish, with controlled unevenness in gloss. Blacks will appear more vivid and there will be less bronzing.
