The Ink Transfer And Image Definition Differences Between Elastomer And Photopolymer Printing Systems, Jason Palmer

All Theses

With recent advancements in elastomer imaging and plate technologies, a study comparing the ink transfer and image definition characteristics of the current flexographic printing systems was conducted. Using a number of print metrics across a variety of testing conditions, overall results suggested that the elastomer printing system laid down more ink and produced shaper printing than the photopolymer printing system. In particular, the elastomer printing system showed greater solid ink densities for the solvent and aqueous ink printing conditions, while the photopolymer printing system showed higher values in the ultraviolet ink printing conditions. Results across conditions also revealed that the …

Comparing Components Of Flexography Printing For The Application Of Oxygen Barrier Inks On Films, Kasey Renee Reed

Graphic Communication

The purpose of this study is to appraise typical components used in flexographic printing to provide more knowledge on the use of printing with functional inks on filmic substrates when printing packaged products inline. An oxygen barrier coating was applied using different plate-screening technologies and anilox rolls. Comparing two plate-screening technologies and three different anilox rolls using oxygen permeability tests helped to conclude the optimum plate and anilox roll solution that best apply the ink for proper functionality of the coating, with minimal ink application as to reduce waste.

Further knowledge of printing oxygen barrier coatings inline will yield results …

Major Trends In Gravure Printed Electronics, Donna Ariel Clark

Graphic Communication

Printing has become a mature industry, forcing printers to create new applications for their manufacturing process. One such application is printed electronics. The gravure printing process allows for incredible speed and exceptional quality for traditional graphic printing. Theoretically, this would be an ideal method for the commercial production of printed electronics. This study analyzes gravure’s capabilities to produce a uniform conductive ink line and what to expect in the future of gravure printed electronics. Printed line properties such as line widening and scalloped edges were determined to impede gravure’s ability to lay down a conductive ink line. Best results were …
