1. On the evaluation of print mottle
Sammanfattning : Print Mottle is perhaps one of the most disturbing factors influencing overall Print Quality. Mottle has traditionally been evaluated by estimating the reflectance variation in the print. LÄS MER
2. On the evaluation oh systematic print mottle
Sammanfattning : .... LÄS MER
3. Variations Related to Print Mottle in Starch-Containing Paper Coatings
Sammanfattning : Starch in paper coatings is known to increase the risk of print mottle in lithographic offset printing. The objective of this study was to increase the understanding of this behaviour. LÄS MER
4. Interfacial Adhesion Failure : Impact on print-coating surface defects
Sammanfattning : The aim of this work was to develop a solid knowledge on formulation effects controlling offset ink-paper coating adhesion and to identify key factors of the coating and printing process affecting it. Focus lay on comprehending the impact of pigment dispersant on ink-paper coating adhesion and ultimately on the print quality of offset prints. LÄS MER
5. Where did the ink go? : The effect of liquid absorption on ink distribution in flexography
Sammanfattning : The appearance of a print is affected by the individual ink layers. If the ink is unevenly distributed on the substrate it lowers the quality. This thesis puts focus on how the liquid absorbency of a coated substrate impacts on the ink distribution in flexographic printing. LÄS MER
