چکیده

Hexagonal dot packing seems to offer benefits for halftone printing compared to conventional square dot packing, but little practical experience has been reported. Taking advantage of recent refinements in digital electrophotographic (EP) printer technology, the authors conducted experiments on a commercially deployable system to assess whether the potential advantages of hexagonal dot packing are economically exploitable.

Enhanced EP halftones with hexagonal dot packing

Hexagonal dot packing offers advantages for electrophotographic (EP) printing over conventional dot placement on a square grid. These advantages derive from a reduced neighborhood with which each dot interacts. Hexagonal dot packing has exhibited better grayscale performance with small clusters. Multiple dot centers in each tile allow obtaining more gray levels for a particular screen frequency...

Analyzing halftone dot blurring by extended spectral prediction models.

Spectral prediction models for halftone prints generally assume homogeneously thick and sharply edged ink dots, i.e., bilevel halftones. In real prints, the ink thickness often decreases at the boundaries of the ink dots, thereby forming continuous-level halftones. The present study aims at verifying to what extent the classical Clapper-Yule and Yule-Nielsen models are able to predict the refle...

Yule-Nielsen based multi-angle reflectance prediction of metallic halftones

Spectral prediction models are widely used for characterizing classical, almost transparent ink halftones printed on a diffuse substrate. Metallic-ink prints however reflect a significant portion of light in the specular direction. Due to their opaque nature, multi-color metallic halftones require juxtaposed halftoning methods where halftone dots of different colors are laid out side-by-side. I...

A mathematical description of the dot diffusion algorithm in image halftoning with application in inverse halftoning

The dot diffusion method for digital halftoning has the advantage of parallelism unlike the error diffusion method. The method was recently improved by optimization of the so-called class matrix so that the resulting halftones are comparable to the error diffused halftones. In this paper, we will give a mathematical description of the dot diffusion method. This description is then applied in in...
