But how can ICC color transformation be utilized in practice? Let’s look at the example in Figure 7. When a user scans a color from a scanner, it reads (R, G, B) = (42, 82, 171). If the user would like to print out the same color as the scanned color, ICC workflow will first transform the scanned color to (L*, a*, b*) = (51, 11, 43) in PCS by using scanner ICC profile. Then by using the printer ICC profile, (L*, a*, b*) = (51, 11, 43) is determined to be (C, M, Y, K) = (57, 29, 9, 0) for the printer. By comparing (R, G, B) = (42, 82, 171) from the scanner and (C, M, Y, K) = (57, 29, 9, 0) from the printer, the user will find the colors are very similar. This illustrates the overall ICC workflow.
