1. Toward better image reproduction in offset
Sammanfattning : This thesis has focused on color reproduction processes in the graphics field and is based on theoretical research and practical studies. The purpose of this thesis was to investigate how new tools and tools adapted to a specific production set-up can be used to raise awareness regarding the quality and workflow of images and image processing for sheet-fed offset within the graphic industry.

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

4. Printability and Ink-Coating Interactions in Inkjet Printing
Sammanfattning : Inkjet is a digital printing process where the ink is ejected directly onto a substrate from a jet device driven by an electronic signal. Most inkjet inks have a low viscosity and a low surface tension, which put high demands on the coating layer’s porosity and absorbency characteristics. LÄS MER
5. Överdosens antropologi : En kontextuell studie
Sammanfattning : The central theme of this thesis is the nature of heavy drug overdose and its social consequences. The aim of the study is to provide a nuanced ethnographic interpretation on the phenomenon concerning drug overdose, especially among drug users using injections as the principle means of administering the drugs.
