Printing using multiple colorants having different saturation can enhance variations of color tones especially in highlight regions. The said multiple colorants include Cyan (C), Magenta (M), Yellow (Y), blacK (K), Light Cyan (LC), and Light Magenta (LM) in this proposed paper. To improve the printing output quality, the implemented kernel technologies involve multi-level halftone, lookup tables of six color transform, 3-D interpolation, and printing algorithm for high resolution rendering. To estimate capability of variations of color tones between amounts of ink drop and different kinds of media, an experiment about ink control is proposed here, and the related data of the experimental analysis can help to determine what amount of ink drop can be absorbed, how to design the proper printing algorithm, and how to design suitable halftoning method based on these printing conditions. Driving tinier and tinier drop size of ink along the development of print head can make the paper absorb more and more amounts of drop, so the printing can render more and more levels of color tones. By the above fact, the multi-color printing technology becomes the major topic of research for these main printer manufactures.
