In a drop-on-demand thermal ink-jet printer, the dot size of an ink droplet expelled from a printer depends on the absorption ratio of the substrate. This causes color differences between output images on different printing materials. A color consistency algorithm for different papers is proposed. To achieve a corresponding color reproduction, dot gain compensation based on saturation was applied to correct the color reproduction of the printer. However, dot gain compensation applied to substrates with different intensity values may still produce unequal intensity values in the output images. Accordingly, intensity compensation is added in order to match the colors of different papers.
