The Study of the Influence of Photoinitiators on Curing Rate in UV System under Different Oxygen Atmosphere
Abstract:The UV system contains prepolymer, monomer and photoinitiator has been broadly used in printing area. UV-curable inkjet ink with its environmental protection, energy-saving, good printing quality and high efficiency has become the most concerned topic and has a good development prospects. The use of UV ink-jet printing ink in ink-jet digital printing is the main development trend of digital printing currently and a period of time in future. Curing rate is one of the most important performance parameters of the UV system which is greatly affected by prepolymer, monomer and photo-initiator, besides that, the oxygen atmosphere is another principal element. In order to investigate the influence of different oxygen atmosphere on the curing reaction, we designed and made a UV curing device with varied degree of oxygen atmosphere to study the effect of photo-initiator species and content on the systems curing rate under different oxygen atmosphere condition.

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.
