Will the traditional film making be replaced by CTP?

From the process point of view, CTP direct plate making is to directly expose CMYK four-color plates on a printer with a computer and wash them with chemicals.

The traditional film printing is that the computer directly explodes the film into a four-color version of CMYK on the film machine, then washes the version with water, and then reprints the four-color version. The difference between the two is direct and indirect.

Relatively speaking, the advantages of ctp plate-making compared with traditional plate-making include: no spots and no net, which can effectively ensure the cleanliness of the layout; Computer imposition, overprinter is more accurate, without manual error; Laser plate-making, digital information processing imaging, to ensure more accurate and uniform dot reduction, the same dot is the same up and down, left and right, basically reaching the state of dot distortion; The net angle is clearer, and there is basically no turtle net in CTP plate making; Dots are sharper, CTP plate making can reach 1% of the dots, while traditional film printing can only reach more than 5% of the dots, so the printing level is better, the three-dimensional effect is stronger, and some subtle places can be effectively reflected, with higher quality and more exquisite effect; After receiving the file, it can be published and printed on the computer immediately, which is more timely.

From the perspective of future development, CTP plate making has obvious advantages in cost, quality and efficiency. The popularization of CTP technology will promote the reshuffle of traditional plate-making center industry. The future industrial pattern will be: large and medium-sized printing plants will purchase CTP to solve the prepress process themselves, and small and medium-sized printing plants will be provided with plate-making services by plate-making centers. On the whole, with the comprehensive popularization of CTP digital plate-making technology, it is a foregone conclusion that printing film will be eliminated.
