What does fast digital printing do?

Abstract: With the development of social economy, digital express printing is becoming more and more common. Digital express printing refers to printing by using modern digital graphic processing technology and direct transmission of digital information technology, which not only greatly improves the printing speed, but also increases the clarity of graphic printing. Therefore, compared with traditional printing, digital fast printing is also called variable information printing or personalized printing. Let's take a look at the content of fast digital printing. 1. What does digital express printing do?

Digital express printing is actually digital express printing or printing.

Digital fast printing is a printing technology that uses prepress system to transmit graphic information directly to digital printing machine through network for color printing. It can be printed on one page, with variable data, and can also spread pictures and texts on various media, which greatly improves the commercial application range of digital images, and is especially suitable for paper printed matter with high quality requirements, many varieties and small batch.

Second, the principle of digital express printing

Digital fast printing system is mainly composed of prepress system and digital printing machine. Some systems are also equipped with binding and cutting equipment. Its working principle is: the operator will output the manuscript (graphic digital information) received from the network system, digital information of digital media, or network digital files to the computer, and create ideas on the computer, modify and arrange them into digital signals that customers are satisfied with. After RIP processing, they are converted into corresponding monochrome pixel digital signals and transmitted to the laser controller, and then the corresponding laser beam is emitted to scan the printing cylinder. The printing cylinder (no printing plate) made of photosensitive material is sensitized to form pictures and texts that can absorb ink or toner, and then transferred to substrates such as paper.

Third, the difference between fast digital printing and printing

1, process

Traditional printing is more complicated than digital printing. Traditional printing process: computer manuscript preparation, color separation film output, proofing, imposition, PS printing, upper printing and four-color printing. There are many processes before and after, and if there are problems such as missing points or inaccurate color registration in these processes, some or all of them will be reworked. However, the digital printing process only needs two processes: computer production and manuscript printing, and the operation is simple. From design to printing, there is no need for film and printing plate, and there is no problem of ink balance. One person can complete the whole printing process.

2. expenses

A. Investor: Four-color printing equipment mostly invests several million yuan, with large equipment area, large production site investment and many personnel. A four-color printing needs 3-4 people, with high technical requirements and many auxiliary equipment, such as plate making machine, imagesetter and proofing machine. However, the investment in digital printing equipment is mostly in the tens of thousands to hundreds of thousands. Most of the equipment occupies a small area, and the digital printing machine occupies a small area. People who know prepress can operate simply without auxiliary equipment.

B. Customer: Modern commercial activities need instant and flexible printing products, while traditional offset printing products with less than 5,000 copies need to bear the printing cost of 5,000 copies. Printing a large number of poor printed materials at one time will reduce the cost of single sheet, but it will also increase the storage cost. Digital short-version printing really caters to the changing needs of commercial printed matter, such as fast printing of printed matter with small quantity and flexible variety.

3. Flexibility

Digital fast printing can change data printing, which traditional printing can't solve.

Digital express printing can correct printing errors in time, and traditional printing needs to be reissued and reprinted when errors are found.

Digital fast printing can print a variety of printed materials, the quantity is small, but traditional printing is difficult and costly, such as publishing house sample books.
