A new thermal ink-transfer color printer has recently been developed. As a result of measuring the spectral reflectance and chromaticities of the colors this printer can produce, it was possible to discern that 1) three ink colors (yellow, magenta, and cyan) are appropriate for use as primaries for color printing; 2) the color gamut possible with this printing method is as great as graphic arts; and 3) yellow, magenta, and cyan was found to be the best order of the overlapping transfer. To clarify the characteristics of multicolor printing using dot-patterns, the color differences for all 2 multiplied by 2 dot-patterns were evaluated. Their chromaticities were analyzed on the basis of Neugebauer's equation, MacAdam's tristimulus values, and simple models that included changes in dot area.
