Offset Printing CTP Plate for Sale

Offset printing is a common printing technique in which an inked image is transferred from a printing plate to a blanket and then to the printing surface. Specifically, the printing plate must be able to transfer the image to paper or other substrate. Printing plates are usually made from aluminum printing sheets. There are mainly two types: offset printing ctp plate and PS plate.

For CTP applications, the first thing that comes to mind is newspaper printing companies. However, judging from the development in the past two years, commercial printing companies, especially those that pursue printing quality, have become the protagonists of CTP applications.

In terms of the CTP printing process, because the layout information of the publication is directly output to the printing plate, compared with PS printing, the film output link and PS plate printing link are reduced, so the cost of the CTP printing link includes: Output digital sample printing fee, printing fee (CTP plate making fee), and printing fee.

Commercial and packaging printing companies that have high requirements for print quality mainly undertake printing tasks such as high-end quality albums and exquisite packaging products, all choose thermal CTP plate. Thermal CTP is characterized by using a laser with a wavelength of 830nm or 1064nm to record the printing plate.

Violet CTP technology uses high-sensitivity violet printing plates specially produced for it. The grain of violet printing plats is finer than that of traditional plates, and the coating process is more complex. Of course, the photosensitive layer is also different from traditional PS plates. After development in recent years, it has become the three mainstream CTP technologies together with thermal CTP and CTCP.

The thickness of the aluminum sheet for CTP plates is generally 0.280mm, which is slightly thicker than the currently produced PS plates (the thickness of the PS plate base is 0.270mm±0.005mm). Some foreign companies also use 0.275mm thick aluminum plate base, and the thickness tolerance is ±0.005mm. If the aluminum plate base is thicker, the printing plates for sale will be stiffer and less likely to bend.
