2. 1. Where did the ink go? : The effect of liquid absorption on ink distribution in flexography

   Author : Sofia Thorman; Li Yang; Magnus Lestelius; Martti Toivakka; Karlstads universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; flexographic printing; print mottle; ink trapping; absorbency; absorption non-uniformity; water-interference mottle; Chemical Engineering; Kemiteknik;

   Abstract : 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. READ MORE

4. 2. Interfacial Adhesion Failure : Impact on print-coating surface defects

   Author : Hajer Kamal Alm; Lars Wågberg; Göran Ström; Janet Preston; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ink-paper coating adhesion; offset printing; calcium carbonate pigments; polyacrylate; dispersant; print mottle; surface chemistry; hygroscopy of surfaces; coating structure; print quality; water interference mottle; Fiber- och polymervetenskap; Fibre and Polymer Science;

   Abstract : 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. READ MORE

5. 3. Ink Jetting of Photochromic Ink : Towards the Design of a Smart Textile Sensor

   Author : Sina Seipel; Högskolan i Borås; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Inkjet printing; UV curing; photochromic; UV-sensing; smart textile; resource-efficient; scCO2 dyeing; jetting; dye kinetics; color performance; durability; stabilization; Textil och mode generell ; Textiles and Fashion General ;

   Abstract : Smart textiles have been a hot topic in research for several decades; however, comparatively few products can be found on the market. Resource-efficient processes can boost the breakthrough of smart and functional textiles, which often necessitate high-cost materials and only require small batches. READ MORE

6. 4. Topographical micro-changes in corrugated board production : effects on flexographic post-print quality

   Author : Marcus Rehberger; Nils Enlund; Gunnar Engström; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; corrugated board; liner; double-facer; double-backer; gloss; surface roughness; micro structure; wear; paper metal friction; flexo; ink-jet; print quality; Cellulose and paper engineering; Cellulosa- och pappersteknik;

   Abstract : The appearance and design of a package are key properties to attract and to focus the attention of a customer. Print quality contributes to a great degree to achieve these requirements. Most critical perceived in terms of quality are print defects like mottling, gloss and stripiness, which all appear in the printing of corrugated board. READ MORE

7. 5. Surface and porous structure of pigment coatings : Interactions with flexographic ink and effects on print quality

   Author : Erik Bohlin; Caisa Johansson; Per Edström; Göran Ström; Karlstads universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Coating; Pigment; Calendering; Porosity; Flexographic Printing; Print quality; Chemical Engineering; Kemiteknik;

   Abstract : Each day, we are confronted with a large amount of more or less important information that we have to consider, and even in our digital society we need paper for communication, documentation and education. Much of the paper we use or are confronted by in our daily life, such as newspapers, books and packages, contains printed images or texts, and the appearance of both the print and the supporting surface is important.
