1. 1. Halftoning for Multi-Channel Printing : Algorithm Development, Implementation and Verification

   Författare :Paula Žitinski Elías; Sasan Gooran; Daniel Nyström; Mattias Andersson; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : A seemingly straightforward way to enhance the quality of printed images is to increase the number of colorants, beyond the four traditionally used, in multi-channel printing. Potential improvements to reproduced images include: increased colour accuracy, enhanced colour smoothness and reduced image graininess. LÄS MER

3. 2. Improving image quality in multi-channel printing - multilevel halftoning, color separation and graininess characterization

   Författare :Paula Žitinski Elías; Sasan Gooran; Daniel Nyström; Marius Pedersen; Linköpings universitet; []

   Sammanfattning : Color printing is traditionally achieved by separating an input image into four channels (CMYK) and binarizing them using halftoning algorithms, in order to designate the locations of ink droplet placement. Multi-channel printing means a reproduction that employs additional inks other than these four in order to augment the color gamut (scope of reproducible colors) and reduce undesirable ink droplet visibility, so-called graininess.
