Scan-to-print color rendering in a system including a scanner engine and a print engine may include, in an exemplary embodiment, storing or providing an index table of respective scanned values in a scanner color space corresponding to each output color printed by the print engine. A color target may be scanned using the scanner engine to provide digital image data in a scanner color space. For each image-scan pixel, a closest scanned value is selected from the index table for a corresponding output color. A color difference is determined a between the image-scan pixel and the closest value as an error for that image-scan pixel. Color error diffusion is applied to compensate for the color difference by distributing the error to neighbor pixels.
