Digital Printing Features and Applications (1)

After the 1990s, with the development of printing technology, the emergence of new process methods, and the widespread use of computer technology in the printing industry, consumers’ demand for printed materials has become more personalized, timely, small-volume, and fast. Requirements, the printing industry has undergone a revolutionary change, the printing process from analog to digital development, the traditional process methods gradually differentiated a new printing process methods - digital printing and computer direct plate. CTP and digital printing have become the development direction of today's printing industry and a hot topic in the industry.

First, the classification of digital printing

Digital printing refers to the direct passage of various manuscripts (characters, images, electronic files, and network files) after they have been input into a computer for processing, without the need for electrical processes such as film output, punching, proofing, and printing on the PS plates. A new type of printing process in which the optical fiber network is transmitted to a four-color printing machine of C, M, Y or K for printing or direct color separation. The current classification can generally be classified into two categories: true digital color press and digital offset printing press (also called on-press-imaging system).

Second, digital printing printing process

The digital printing system is generally composed of a graphic and text integrated prepress processing system and a digital printer or phototaking system. The operator enters the computer (prepress processing system) into the computer (prepress processing system) according to the user's request and the manuscript provided or from the internet network system to input the customer's data file (generally a PDF file) or the customer's own electronic file; The processing of graphic and textual data enables the image to be subjected to useful adjustments such as color, gradation, and gradation, and to carry out creatives, modifications, and text synthesis that meet the user's requirements, and then edit and typeset the graphic and textual information, and eventually the ideal pattern, The text is organized into content and form that the user is satisfied with. The digitized information is finally rasterized by RIP to generate a corresponding monochrome pixel digital signal; then the digital information is output to the electronic data control center, so that color separation can be performed, and digital signals can also be transmitted to the printing press. The laser modulates and emits a corresponding monochromatic laser to scan the plate cylinder. The plate cylinder made of photosensitive material can absorb ink or ink particles after being sensitive, so that the graphic information can be transferred to printing. On the object, complete the printing.

Third, the characteristics of digital printing

1. The file compatibility is good and easy to operate. Digital printing can accept the output printing of computer files such as Photoshop, Freehand, Pagemaker, Quarkxpress, CroelDraw, etc. and the general documents and images are first edited on a computer and then output printed, and the digital printing data source can be directly obtained from the internet. The client transmits his or her graphic information to be printed to the printing professional company he or she is satisfied with. The printing professional company will perform various processing and then transmit the proofing effect to the customer via the Internet. If the customer is satisfied, he can directly go to the machine. print. Digital printing has low requirements for documents, and it can accept various formats of Mac and PC files that are favored by designers of many advertising agencies. It is also convenient and fast for the reception and processing of remote PDF data information. The speed of digital printing.

2. The process flow is greatly simplified and the customer's delivery time can be met more quickly. After digital printing receives customer's satisfied computer files, it can directly generate PS files through fast software and hardware RIP; it can also be directly divided into four-color film through electric sub-system. After printing, it can be processed by printing plate with ordinary printing plates. print. Digital printing usually prints one or two proofs of a printed matter. After the standard test strips are tested and debugged, the finished products can be printed, and the customers are not satisfied with the defects directly, convenient and timely, and the traditional printing process, including output power distribution, Compared with the procedures of proofing, imposition, printing on the PS, and on-machine, it greatly saved time and reduced production costs. Prints that can usually be delivered in 3 or 4 days can be delivered in just a few hours.
