Development of Digital Photo Prints for Thermal Dye Transfer Method
Abstract:Recently with rapid spread of digital cameras, we find growing needs for digital photo printing. Out of many digital print methods, thermal dye transfer method excellent in print speed, photo quality, and preservation, is recognized as a method which can print high quality image matching that of silver-halide and that instantly. This method, because of its fast output and ease of use, is widely utilized as an effective means for kiosk terminals and on-demand printing at retailers. We, at DNP, in search for further performance improvement, have shed light on and researched improvement of high sensitivity and preservation of this thermal dye transfer image.
Improvement of image's high sensitivity has been achieved by adopting a new adhesive/barrier layer in order to transfer the dye in the transfer film (ink ribbon) more effectively to the receiver. As for preservability improvement, we have successfully developed a new dye structure excellent in inter-dissolution stability with resin (binder) that comprises dye and durable against external factors such as light, heat, humidity, etc.
With these new technologies, we will be able to obtain images with high speed output instantly on the spot, a beautiful photo print with high contrast and wide tone range, a beautiful photo print with negligible deterioration of photo quality by light and heat, etc.

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.
