The PS And CTP Printing Plates in China
The PS and CTP pringting plates for offset printing features high printing quality, strong printing resistance, environmental protection, reasonable cost, high resolution, clear writing, fast speed and strong reproducibility. The aluminum plate base is 1050, 1060, 1070 and 1052 alumnum plate, of which the aluminum content is ≥99.50%, ≥99.60%, ≥99.70% and ≥99.52% respectively.
Aluminum plate base has the advantages of low density, high strength, moderate wear resistance, easy processing, good shape, good hydrophilicity, high stability, good surface treatment, strong recyclability, easy regeneration, abundant resources andreasonable price, etc,, which makes it an indisputable high-quality PS/CTP plate substrate.
The average annual growth rate of China’s PS/CTP plate output from 2005 to 2011 was 21.32%. The growth rate of the domestic production from 2011 to 2015 was 11.2%. At present, China has become a net exporter of PS/ CTP plate.
For PS plate making, there are two kinds of raw materials: the continuous cast-rolling strip and the ingot hot-rolled strip. The PS plate quality made of them are almost equal. For CTP pringting plates, the better choice is to use the ingot hot-rolled aluminum.
In the production of CTP plates, the pure stretch straightening production line is indispensable. It plays a very important role in ensuring product flatness and performance. Up to now, many CTP plates manufacturers such as Haomei Aluminum has such production line.
As for the composition of the alloy, there is still a lot of work to be done. Although the aluminum base plate used in PS/ CTP plate are 1000 series aluminum, from our work experience and metallological principles, we should regard this type of alloy as Al- Fe-Si alloys. The Fe/Si value must reach a certain ratio in order to produce high-quality aluminum sheet. It is better that the Fe/Si value is between 2.5 to 3.5.
Haomei Aluminum has insisted on improving alloy composistiong and processing technology to get the best aluminum base plate for PS/CTP plate. Welcome to leave message below to get the latest price of PS plate and CTP plate.
