Printing press in the digital age (I)

digital technology drives the upsurge of technological revolution in all walks of life, and the printing industry is certainly not willing to be outdone. However, compared with the rapid development of digital prepress in recent years, the development of printing seems to lag behind. For offset printing, which occupies the main position, the degree of automation of the printing machine is getting higher and higher, but the time of printing a printed matter has not increased much. It takes at least half a day from the film to the completion of printing, and it requires a lot of people to cooperate closely. When there is something wrong in the rush, the delivery date will be postponed, which means that this business may not be profitable. In order to shorten the production cycle of offset printing and improve flexibility, the key is to realize the digitization of large version and proofing, no longer need the use of film, and realize the last minute modification before printing; Combined with direct plate making technology and automatic printing machine, the printing preparation time is shortened. To meet all requirements, the answer is only two words - "Di"

Heidelberg has always been the mediator and leader of Di technology. Since the first gto-di in 1991, there are still 92 in use. In 1995, it launched the famous octa open model: kuaba QM Di, and the installed capacity in the world has exceeded 1500. 1 when the aging temperature was between 690 ~ 720 ℃, Shanghai Debao, an IPEX exhibition in 1998, once again introduced the four opening model: speedpa SM 74 Di, which represents the highest technical level of offset printing machine now. Whether in terms of quality, efficiency, economy and flexibility, as well as the degree of automation, s shows its excellent ability because plastic needs high temperature m 74 di

top quality

sm 74 Di is mainly composed of three parts. The printing unit is Heidelberg's famous Speedmaster SM 74, which is the guarantee of stable production and high quality. Each color deck is equipped with a laser imaging device controlled by CP2000. Combined with delta rip, you can directly accept various digital documents before printing and directly image and print on the printing machine

digital files are first raster processed by delta rip to generate bitmap files, then imaged by laser on a non rinsing thermal plate, and then printed. The processes that need to be strictly controlled such as film washing, plate printing and plate printing are omitted, and there is no loss of quality in the whole imaging and plate making process

direct imaging:

according to the information of electronic documents, the laser directly forms points on the printing, which makes our control of points very direct. Because the printing plate does not need developing and developing, the accuracy of dots is even higher than that on the color separation film, which greatly saves time and energy for plate making quality control

point quality:

sm 74 Di adopts thermal imaging technology, integrates stability and high quality, and operates under visible light. 2400dpi imaging accuracy, up to 225lpi can be printed. The square dot laser technology, combined with the heat sensitive version without washing, forms a particularly sharp dot edge, dot expansion size, fast inking, and strong ink storage capacity

addition technology:

sm 74 delta rip in the front end of Di uses HQs and is addition industry to show the overall scope and intensive development trend technology, automatically optimizes the angular arrangement, and can choose different point shapes to avoid collision. At the same time, you can also choose Heidelberg's "diamond" (FM) plus technology. Because there is no point loss in plate making, SM 74 Di can easily do FM, which is very difficult for traditional offset printing, making many SM 74 Di users feel superior. Because they can provide customers with FM printing albums, handicrafts, photographic works and many other prints with very high quality requirements, which is difficult for ordinary offset printing users

the main cause of error is that dust and oil dirt make the gear rod astringent or worn; In addition
