A Critical Review of Spectral Models Applied to Binary Color Printing
نویسنده
چکیده
The recent increase in the use of desktop color applications has increased the need for color management systems, which in turn depend upon device profiles to exchange color information. Device profiles for color printers are based upon printer models. The typical desktop-color user has a binary (halftone) printer. Many models have been proposed for binary color printers; these are traced beginning with the work of Murray and Neugebauer, on through Yule-Nielsen and newer forms, ending with more recent work involving cellular Neugebauer and first-principals models. To focus the modeling on the physical printing process, spectral reflectance is most useful for device profiles. The models are tested with sample data and an evaluation is made comparing the various forms. The best models for the sample data were found to be Yule-Nielsen with single n-value and YuleNielsen varying n-value as a function of wavelength.

In printing, halftoning algorithms are applied in order to reproduce a continuous-tone image by a binary printing system. The image is transformed into a bitmap composed of dots varying in size and/or frequency. Nevertheless, this causes that the sparse dots found in light shades of cyan (C) and magenta (M) appear undesirably noticeable against white substrate. The solution is to apply light cy...
