Multilevel halftoning using multiscale error diffusion
The advance in printing technology makes multilevel halftoning become important as printers can now print inks of different intensities. This letter presents a multilevel halftoning algorithm that is based on multiscale error diffusion. This algorithm takes care of the constrained pixels before handling the unconstrained pixels and diffuses errors with a non-causal filter such that halftones of...
متن کاملColor prediction modeling for five-channel CMYLcLm printing
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...

متن کاملN-Ink Printer Characterization With Barycentric Subdivision
Printing with a large number of inks, also called N -ink printing, is a challenging task. The challenges comprise spectral modeling of the printer, color separation, halftoning, and limitations of the amount of inks. Juxtaposed halftoning, a perfectly dot-off-dot halftoning method, has proved to be useful to address some of these challenges. However, for juxtaposed halftones, prediction of colo...
