Abstract:

The usage of specifically coated paper can overcome some limitations of the common inkjet technology. However, even these special papers could not improve the limited water resistance of the inkjet images, so inkjet images still show disadvantages which limit their usage in the high-performance fields of application.

The special polymer “Allessan® APT” which is commercially available in large scale for the production of highly sophisticated inkjet paper can overcome these limitations.

Allessan® APT, the new additive for paper treatment can be applied on paper via a separate coating step or can be added directly in the size-press. Allessan® APT is an easy to handle aqueous solution.

The compound has the effect that the color is retained near the surface and the liquid ink carrier is bound on the paper, preventing colors from streaking or fading during the printing process, and even when exposed to water. The material can decrease the ink-drying times and increase the color density to obtain brighter, more vibrant colors.

The combination of special papers treated with Allessan® APT and the inkjet technology based on water-soluble printing inks can lead to new opportunities and new application fields of inkjet application and can increase the future potential of the inkjet technology.

  • 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.
