Canon PFI-1100CO Chroma Optimiser 160ml for Pro-Series 2000 / 4000 / 6100S

When you print something, Chroma Optimiser is put on top of it like a clear coat. This has the effect of filling in the gaps between the distinct ink droplets, resulting in a uniform layer of ink without any troughs or ridges. This innovative coating enhances the depth of black in printed images and effectively eliminates issues such as bronzing and gloss differential that have long plagued inkjet printing.
