Talking about Printing Technology Suitable for Small and Medium-sized Printing Enterprises (II)

Flexographic printing uses prefabricated photosensitive resin plates, which can produce images of 130 to 150 lpi. The printing plate's printing rate is as high as 50 to 1 million printing. The plate making equipment investment is small, and it is suitable for short prints of small quantities and miscellaneous varieties. China's current demand for packaging and printing, flexographic printing more use of water-based ink, in line with the green printing environmental protection requirements.

After the computer technology was applied to the flexographic printing, the positioning registration, tension control, screen display quality tracking and feedback were automated, the time was saved, the operation difficulty was reduced, and various complicated operations and necessary parameters could also be utilized by the computer. Programming and storage of the program, when the product is repeatedly printed, enabling the storage device can make the complicated operation easy.

Flexographic printing is particularly suitable for small-volume, small-scale packaging prints. With the continuous improvement and improvement of the supporting technology of flexo printing machines, materials that are difficult to print in the past, such as extremely thin films, and materials that do not absorb ink, can be printed at high speed. , If directly equipped with a variety of features of the post-press processing equipment, die-cutting, capping, bronzing and other follow-up work, can shorten the production time, reduce paper consumption, print quality and stability.

4 screen printing

Modern screen printing technology is not only technically different from the other three types of printing, but also the most widely used of the four printing types. Its printing objects can be paper, paper cups, wooden products, plastics, ceramics, metal , Fur, etc. It can not only print flat objects, but also print round, convex, concave and irregular shaped objects. Therefore, screen printing has the characteristics of wide application, low cost of plate making, thick ink layer, low investment cost and good economic benefits.

In terms of image transfer process, although there is no obvious development stage in screen printing technology, its principle stems from the simple copying of stenciled wax paper, which is an ancient civilization and one of the oldest methods of image reproduction, but it is different from Ancient wax paper copying, just as modern letterpress printing is different from letterpress printing technology in Gutenberg, along with the economic development and the progress of human society, it is also constantly making technical progress and improvement, and its development prospects are very high. broad.

5 digital printing

Digital printing is the inevitable outcome and development trend of digitization and networking of printing technology. The development of digital printing technology and equipment is the focus of attention in the industry. Digital printing has attracted many businesses because of its many advantages in the market and application. Interest and enthusiasm for participation. On the one hand, equipment suppliers have launched their own digital printing equipment. On the other hand, the market is full of expectations for the prospects of digital printing. At present, digital printing machines mainly include the following types of equipment. One is the DoCU6135 from Fuji Xerox. Heidelberg's DM9110 and Hewlett-Packard Digital's press1000, the advantage of such devices is to achieve variable data printing, a print, personalized printing; the other is Heidelberg's DI-46, Japan Screen's TruePress544 As the representative of the machine directly plate digital printing press, their advantage is to optimize the process flow, is suitable for printing the number of printing business is 300 to 5000; In addition, there are digital printing machine using inkjet technology, mainly used to print a large number Bills, commercial papers, etc., Sai Angel inkjet system is representative of this type of product.

Digital printing (digital printing) is a digital technology that replaces traditional analog information and directly transfers digital images to printing materials. The industry generally divides digital printing into two types: machine imaging printing and variable data printing. Digital printing is a very comprehensive technology that covers many technical fields such as printing, electronics, networking, and communications. The so-called digital printing is the use of computers directly transmitted to the printing presses, thus eliminating the process steps of color separation, imposition, plate making, test run, etc. It brings printing into one of the most effective production methods, from input to output, the entire The process is controlled by one person to realize a print and print on demand, which solves the problems of traditional "first printing, post-distribution" errors, freight turnover and other issues.

Compared with traditional printing, digital printing has the following advantages:

1) Convenient and quick digital printing eliminates the need for tedious processes such as film, imposition, and printing. It has absolute advantages in a small amount of printing and urgent work. All typesetting software, design software and electronic documents generated by office application software can be used. Direct output to a digital press.

2) Fully digitalized flexible and efficient digital printing can provide users with more flexible printing methods, namely edge-to-edge printing, edge-to-edge printing, and truly zero inventory. This flexible and fast printing method enhances the customer's competitive environment in every minute. In the advantages.

3) It is not necessary to print a large quantity of printed matter, and it does not require printing, and one copy can also be printed. Digital printing can achieve a desirable effect such as on-off printing.
