The digital printing major is based on the printing business of universities

Students in this major mainly study system knowledge related to promoting culture, knowledge dissemination, and digital printing process design, development, and evaluation. They have print media preparation, digital printing process design, material selection, post-processing, computer integrated printing control, and quality. Basic theories and skills in testing and other aspects, with the basic ability of relevant units to engage in professional work.

This specialty trains senior engineering and technical personnel who have the concept of a digital printing system and can work as digital printing solution planning and process design, production implementation and process control, production organization management and scientific research in various digital printing and rapid printing enterprises and scientific research units.

After graduating from this major, students can engage in research and production at digital printing companies, fast printing companies, professional computer plate-making companies, inkjet photo companies, advertising companies, newspapers, publishing houses, multimedia production companies, and printing equipment companies.

Introduction to Digital Printing

First of all, we must understand the definition of digital printing: digital printing is to directly record digital graphic information on printing materials for printing. In other words, the input is a digital stream of graphic information, and the output is a digital stream of graphic information.

Digital printing process: The printing process in the digital mode also needs to go through the analysis and design of the original, the processing of graphic information, printing, and post-processing. It only reduces the plate making process. Because in the digital printing mode, a digital stream of graphic information is input, and a digital stream of graphic information is output. Compared to the DTP system in the traditional printing mode, the output method is different. Traditional printing is to record and output graphic information on film. In the digital printing mode, the digital graphic information is directly recorded to the printing material. on.

The development of digital printing: According to authoritative survey data, by 2007, the number of color digital printing companies will increase by 23%, and the growth rate of color digital printing equipment will exceed 56%. From the perspective of competition among printing companies, compared with some companies on the market that cannot perform post-processing, digital printing companies that add efficient binding equipment can speed up the entire workflow from printing, post-processing to delivery. The delivery time and lower cost provide more comprehensive services. In this way, the overall process time and cost savings become a very powerful competitive weapon.

In the field of printing, CTP contains the following 4 meanings:

(1) Computer to Plate: From the computer directly to the plate, which is often referred to as "offline direct platemaking".

It was originally developed from photographic direct platemaking. All plate-making equipment use computer-controlled laser scanning imaging, and then develop into a printing plate through processes such as development and fixing. This technology transforms text and images into numbers, eliminating film as an intermediate medium, reducing the quality loss and material consumption of intermediate processes.

(2) Computer to Press: From the computer directly to the printing press, which is often referred to as "on-machine plate making".

It mounts the printing plate on the cylinder of a digital printing machine, and then outputs the graphic information directly to the printing plate through a laser beam controlled by a computer, and then starts printing. At present, this printing plate can record pictures and texts, but cannot be erased, and can only be used once.

(3) Computer to Paper / Print: Directly from the computer to paper or prints.

Computer to Paper is equivalent to inkjet printing, that is, the inkjet head is controlled by a computer to directly print tiny ink droplets on the paper to form graphic information.

Computer to Print is equivalent to a laser beam controlled by a computer to output graphic information directly to a "printing plate", and then start printing.

(4) Computer to Proof: Get proofs directly from the computer, that is, digital proofing.

Digital proofing is an important part of the digital control process in the prepress field. Its purpose is to check the print quality and the customer's confirmation of the printing effect. Due to low price and high efficiency, digital proofing is gradually replacing some traditional analog proofing.

In general, CTP technology refers more to Computer to Plate technology.
