In order to produce color ink jet prints with good fastness properties, the use of special coated papers is generally essential. The use of modified conventional coating pigments has been suggested as a means to obtain a coating that combines the good properties of silica-based ink jet coatings and conventional coatings. This study examines light and water fastness of dye-based ink jet prints on coated papers containing modified conventional pigments. The properties of the coatings were altered by using different ratios of coating pigments, and the types of binder and dispersant. Inks with known composition were used for test printings. The fastness properties of the prints were analyzed both conventionally and with FTIR and Raman spectroscopy.

This study indicates that light and water fastness of ink jet prints is amended distinctly when the modified coating pigments are used instead of pigments intended for conventional printing papers. However, mechanisms that govern the build-up of light and water fastness of the studied dye-based inks depended also on the polymer system of the coating. The data suggest that on cationic PVA + p-DADMAC coatings primarily the chemical paperink interactions contribute to fastness properties, whereas on weakly cationic latex-starch coatings structural paper properties have relevance as well.

  • 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.
