he differences between CTP plate and PS plate on the dimension requirement of aluminum plate base are about the thickness, the width and the longitudinal and transverse uniformity.

1) the thickness difference of aluminum base plate. The thickness of aluminum plate base for CTP plate is generally about 0.280mm, which is slightly thicker than that of PS plate produced at present (the thickness of PS base plate is about 0.270mm). Aluminum base plate is thicker, the plate stiffness will be better, not easy to bending.
2) the difference of width. CTP plate production in China is generally not install the line edge cutting device, so the width tolerance is required less than 0.5mm, the best without tolerance. The cutting quality has clear requirements, both sides should not have burr, lotus leaf edge after slitting.
3) longitudinal and transverse uniformity of aluminum base plate. The longitudinal and transverse thickness tolerances of aluminum base plate shall be less than 0.005mm. The making machine setting thickness of plate is 0.280mm or 0.275mm. The thickness deviation will affect the parameters of the CTP plate, and plate making machine setting is generally not allowed to adjust.
Positive Thermal CTP Plate specially used in a variety of commercial printing and newspaper printing environment. Have clear dots, distinct, good ink-water balance, high press run and wide adaptability, etc. Whether conventional dampening or alcohol dampening, it can print out clean,clear and accurate color printings.
Thermal CTP Plate Features:
![[Image: thermal%20CTP.jpg]](http://www.ctp-plate.com/images/thermal%20CTP.jpg)
Type:HLR
Uses: commercial printing and newspaper printing environment.
Thickness:0.15-0.3mm
Laser energy required 120mj/cm2
Spectra Sensitivity 830nm
Resolution 1- 99% @ 240tip/10
Coating: blue
Strong stability: There are all imports of high-speed automatic CTP production line, pipe production process standardization, product parameters are very stable. Cost-effective: the use of high sensitivity coated plate high efficiency, extend the life of thelaser platesetter. Printing plates high resistance to printing.
Easy to apply: bright room, rapid exposure and without preheating.
Superior quality: high resolution, up to 10um Fm network, to restore the good level of detail and print.
