Gelatine as receptive coating of photo paper is known for high quality prints with high gloss. The light fastness and color density of prints on gelatine coatings can hardly be beaten by any other coating.

On the other hand mat inkjet papers very often suffer from poor color density of the prints, resulting in pale colors. GELITA has investigated combinations of pigments like silica or carbonate with gelatine. Mat papers were obtained with excellent color density of the prints. In detailed investigations we have identified several formulations which give mechanically stable coatings (no dusting) and result in instant dry prints. Increase in color density of more than 30% in comparison to office paper could be detected. The high color density in combination with the other properties of the coatings offer the papermaker a lot of new options to create either high end mat inkjet paper with better performance cost ratio or ‘upgraded’ inkjet paper with interesting economy. The formulations can be applied by blade coating or film press device. Therefore different coating weights and paper qualities can be produced. The findings presented here have been filed as patent application. The experiments have been performed on a lab scale and further improvements by scale up can be expected.

More about this publication?
  • For more than 30 years, IS&T's series of digital printing conferences have been the leading forum for discussion of advances and new directions in 2D and 3D printing technologies. A comprehensive, industry-wide conference that brings together industry and academia, this meeting includes all aspects of the hardware, materials, software, images, and applications associated with digital printing systems?particularly those involved with additive manufacturing and fabrication?including bio-printing, printed electronics, page-wide, drop-on-demand, desktop and continuous ink jet, toner-based systems, and production digital printing, as well as the engineering capability, optimization, and science involved in these fields. In 2016, the conference changed its name formally to Printing for Fabrication to better reflect the content of the meeting and the evolving technology of printing.
