HG/T 4244-2011 is the English-translated version of 830nm热敏CTP版用红外吸收菁染料.
HG/T 4244-2011 is a recommended Chinese chemical industry standard covering infrared absorbing cyanine dyes for 830 nm thermal CTP plates. It lays down the requirements for the dye and the matching sampling procedure, test methods and inspection rules, together with the provisions for marking, labelling, packaging, transport and storage. The material concerned works as a photothermal conversion agent, which is why the standard is aimed at the dye grades used in digital thermal computer-to-plate platemaking at an exposure wavelength of 830 nm. Testing is carried out with GB/T 1650, GB/T 2374, GB/T 2381, GB/T 2386, GB/T 6679, GB/T 6682, GB/T 8170 and GB/T 25248-2010. Issued on 20 December 2011, it has applied since 1 July 2012.
