CTP technology is superior to traditional platemaking process features

Good print quality

Because CTP technology does not use film anymore, but directly displays the image on the printing plate by light energy or heat energy. Therefore, the dots on the printing plate are the dots that are directly imaged at one time, eliminating film defects and plate-making defects caused by dust. , It is cleaner and clearer than the dot on the ordinary PS plate. At the same time, due to the reduction of processes, many variables in the platemaking process, such as film development, exposure, and chemical development drugs, are avoided. This also makes the possibility of human error in the process of plate making greatly reduced, and the stability is much better than the ordinary PS version. In addition, CTP technology uses a more accurate plate positioning technology, eliminating the manual imposition error, the completion of the four-color version of the repositioning accuracy up to micron level, in the printed matter, the brightness adjustment error is almost negligible. Visible, CTP technology will inevitably improve the printing quality.

2. Shorten production cycle and save labor costs

The traditional plate making process takes 40 minutes from the time the film is discharged to the printing plate. Especially when the layout is more concentrated, the time required is longer, and the situation such as the printing machine is often encountered. The CTP technology can generally preview, layout (layout the layout required by the customer), and directly image the plate material through light energy or heat energy, thus eliminating the need for photofinishing, manual imposition, and printing processes. It takes only a minute or two to fight a four-color version of the four-color version, and it takes only about 10 minutes to output a four-color version, which saves nearly 30 minutes compared to the traditional plate-making process. This avoids the need for a printing press in the traditional platemaking process. phenomenon. In addition, the preparation time for printing and the cost of preprinted paper and ink can be greatly reduced.

3. Remote copying can be done to achieve on-demand printing

As a commercial tool, the Internet connects print shops with customers and suppliers to complete sales, distribute prints, manage print production, and order consumables. There are many printers now have network connectivity and use e-mail for business contacts. Some also set up their own web pages. CTP technology fully adopts digital process flow, which provides convenient conditions for offsite printing of web uploads. Moreover, CTP can achieve "RIP once, multiple output", that is, once a file is interpreted by a RIP into a vector format, after forming a dot matrix array, the data can be stored on the hard disk, multiple times of output, and the remote transmission is convenient and rapid. Edition to achieve on-demand printing.

4. Achieve green plate making

The no-extraction thermal plates used in CTP technology can be operated in the open chamber and do not require chemical flushing. Compared with the traditional platemaking process, no longer using the development of drugs, thus avoiding the production of toxic substances such as waste water, protect the environment, and truly realize the green plate.
