Metamerism, Color Inconstancy and Chromatic Adaptation for Spot Color Printing
The use of metamerism index & color inconstancy index is studied for approval of spot colors used in decorative gravure products, especially spot colors, which are viewed under different light sources at the customer’s end. This work shows that the metamerism index is not sufficient for approval of spot colors, because it doesn’t provide any idea about how colors will transform under different ...
متن کاملRanked dither for robust color printing
A spatially-adaptive method for color printing is proposed that is robust to printer instabilities, reproduces smooth regions with the quality of ordered dither, reproduces sharp edges significantly better than ordered dither, and may be less susceptible to moire. The new method acts in parallel on square, non-overlapping blocks of each color plane of the image. For blocks with low spatial acti...
متن کاملAluminum plasmonic metamaterials for structural color printing.
We report a structural color printing platform based on aluminum plasmonic metamaterials supporting near perfect light absorption and narrow-band spectral response tunable across the visible spectrum to realize high-resolution, angle-insensitive color printing with high color purity and saturation. Additionally, the fabricated metamaterials can be protected by a transparent polymer thin layer f...
متن کاملModel Based Color Separation for CMYKcm Printing
Recently, with the advent of printers with more than four colorants, the development of characterization and calibration techniques for these printers has been an important area of research in color printing. In addition to the ”hi-fi” printers having colorants such as green, orange, red, blue and violet to increase the gamut of traditional CMY K (cyan, magenta, yellow, black) printers, CMY Kcm...
متن کاملDirect Color Consistency Control for Xerographic Printing
The digital color printing process can be described by the color reproduction characteristics (CRC) function that maps the input color to the output color. The CRC map is high dimensional in that there are potentially high number of output colors that a digital color printing process can reproduced. To maintain color consistency, it is desirable to have the CRC to match the desired CRC map at a...
