With the increasing maturity and the rapid development of CTP technology, as well as the declining of price, CTP technology has been more and more welcomed by the majority of printing practitioners, usage of CTP plates have the potential trend to catch up with the traditional PS plate. The overall requirements of the printing plate is very high, especially the current CTP plate is mostly used for high-grade color printing plate, to ensure the quality of the plate, the plate based apparent quality is the premise. The characteristic of CTP technology is the quality of CTP based plate, such as the apparent quality, physical property and electrolytic performance. The aluminum plate base is widely used according to CTP plate technical requirement. The difference between CTP plates and PS plate on the apparent properties of aluminum plate base are as follows. The basic appearance requirements of the aluminum base plate is clean and smooth, no cracks, corrosion pits, air vents, scratches,...
The coated aluminum sheet produced by Haomei Aluminium has grade of 3003 and 3004, the coating has PE and PVDF. Generally speaking, there are five processes in the production of color-coated aluminum coils, namely coil input, cleaning and chemical treatment, painting, curing and finished product output. 1, Raw material roll input. This step is the continuous uncoiling of the decoiler to ensure the continuous and stable input of the aluminum coil to the production line. Some adopt a cross-rotating beam-type coil carrier, and some adopt two alternate decoilers set up front and back; 2, Surface cleaning and chemical treatment. This process is to clean the upper and lower surfaces of the color coated aluminum coil and perform chemical pretreatment to ensure that the paint can adhere firmly; 3, Paint. There are at least two roller coaters in one production line to ensure the smooth coloring of the top coat and primer coat; 4, The paint layer is...
