Development of Digital Quasi-embossing Technology with an Inkjet Printer
Abstract:Emboss technology utilizing hot-stamping method can produce stereo-printed images with metallic gloss. Conventional emboss method needs an engraved plate and consequently becomes costly especially for a small quantity production. We have developed a new technology with combining UV-curable inkjet printing and hot-stamping processes, where any engraved plates are not used. The new technology called “Quasi-embossing Technology” consists of the following three steps: (1) On the basis of three-dimensional image data, stereo-printed images are formed with a UV-curable inkjet printer, where the print-head accompanying a UV irradiation setup scans several times. (2) A metallic foil which has a hot-stamping adhesive layer is placed on the stereo-printed image with supplying heat and pressure from the back of this foil. (3) After having been cooled, the surplus foil around the stereo-printed images made from UV-curable inkjet ink is removed. Finally three-dimensional products with metallic gross are obtained. This technology is applied to produce various products including conventional emboss printing ones.

For more than 25 years, NIP has been the leading forum for discussion of advances and new directions in non-impact and digital printing technologies. A comprehensive, industry-wide conference, this meeting includes all aspects of the hardware, materials, software, images, and applications associated with digital printing systems, including drop-on-demand ink jet, wide format ink jet, desktop and continuous ink jet, toner-based electrophotographic printers, production digital printing systems, and thermal printing systems, as well as the engineering capability, optimization, and science involved in these fields.
Since 2005, NIP has been held in conjunction with the Digital Fabrication Conference.
