The machine pursues the quality of the picture quality and printed products, and the resolution is increased from 400dpi to 600dpi. Moreover, the gear drive is used to improve the overprinting accuracy, so that the original is fixed more accurately, and the design is novel and desirable. High-speed printing is divided into 120 sheets, which can meet the requirements from A3 to postcard specifications.
Based on Konika's digital copy printer 7060, the network printing system Crever Press connected to a personal computer via RIP was jointly developed by the Xingle printing machine and the Konika business machine. The new versions are Crever Press, Pro and Crever Press, Ultra, which have improved the original performance and added new features. Due to the high speed of the output speed and the rapid page processing method from the first page, scanning and printing, the productivity is enhanced, and the functions corresponding to thick paper and postcards are enhanced, and the practicality is greatly improved.
Fuji Xerox's Docutek 6180 is a continuous processing on-demand publishing system from print instructions to binding. Showa Information Machines' Versamark is a super high speed printing system. Add the necessary functions to the customer's needs, using the component approach. Depending on the printing speed, there are two types of 90-100 models (printing speed of 100m per minute) and 90-150 models (printing speed of 150m per minute), which can cope with monochrome printing and high-profile color printing. The NP-V200 of Dainippon Screen can process RIP processing of digital data such as Postscript files at ultra-high speed, and output it to A3 wide-format printing paper at a maximum of 600 dpi. It is printed on 400 pages (A4 horizontally and double-sided) and 200 pages (A3 vertical and double-sided) per minute.
Web offset presses are also available for small batches
Originally adapted to high-speed, high-volume printing web offset presses, with the changes in demand, recently sought to adapt to a variety of varieties, small batch online processing. Last year, at the IPEX show in the UK, the shaftless offset rotary press attracted people's attention. At the IGAS in Japan's 99th year, only the Miyagawa company corresponded to the small-volume and multi-variety A2 specification offset rotary press Alber Press and Tokyo Machinery Manufacturing Co., Ltd. Production of B off-column offset printing machine Colortop3000CM. The Alber Press is a compact version of the sheetfed double-sided machine. Use UV inks for all purposes such as product samples, brochures, advertising, mail order, postcards, business documents, and more. It can be used as a processing 呎吋 output of A2A3A4×2 specifications for sheet-fed, web, folding-fold, and full-page folding, so there is no need for post-processing such as cutting.
The Corortop 3000CM is a shaftless unit between the units that can be adapted to the shop floor to significantly reduce the production floor. The plate cylinder and blanket cylinder use a narrow-gap roller for printing speeds up to 850 rpm.
The system series of Komori Printing Co., Ltd. can be used for everything from the pursuit of versatility to the B-long 4 start-up of small batches, and the efficient A-crossing machine for productivity. Shorten the plate change, replace the folding time, and the operation is much simpler. The System35S, System35II is cleaned and cut out on a B4 x 2 page with a tipless cut and bundled with a take-up strapping machine.
As for the peripheral equipment of the offset rotary press, Quardtec's color control system. This is a scanning system dedicated to the online video substrate of an offset rotary press. In the printing process, in order to improve the accuracy of color reproduction, the color measurement information is automatically detected, and the micro color scale is automatically detected, and after the adjustment, the density information of the color is transmitted to the operator of the printing machine. The necessary corrections are then automatically sent to the ink control station. According to this, in the start of the printing machine, it is possible to meet the requirements of the customer's processing order, and to promote the consistency of the print processing degree of each operator and each workshop, which is very desirable.
Watching the next century digital offset rotary machine
The development trend of digital offset printing in the next century is like Goss' AdoptCP, Man-Roland's Dicoweb, Toyo Ink and Canada's Elcosy's Elcography. All of them are demanding products that are suitable for a variety of small batches, low cost, and the like.
AdoptCP is a computer graphics technology that relies on core technology and can record and print on the plate cylinder repeatedly. This is its basic structure. In terms of image formation, it is scanned with copper on the basis of a digital signal on a plate cylinder coated with nickel crystals. This technology is a unique technology patented by Goss. Copper can be recycled after the image is erased. The hardness of the nickel crystal is high, and it does not need the post-processing (baking treatment) required by the PS plate. Millions of prints. Another feature is the variable size. The plate cylinder and the blanket cylinder are a shell structure, and the thickness of the shell of each of the special fiberglass can be changed to change the specifications.
Dicoweb directly records the image with a laser on a sleeve-type plate cylinder. After printing, the image is removed and a new image is formed. There is no need to replace the version when the work content is changed. The sleeve plate cylinder also performs continuous image printing for 360° imaging. The web has a width of 140 mm and is a CTP (Computer to Press) with an image size of 100 mm. The plate cylinder is covered with a sleeve plate coated with a hydrophilic polymer. The image has a dot size of 11 microns and can be printed at 2400dpi with high resolution. The imaging speed is 2 minutes and 40 seconds for A4 and 5 points for A3. After the end of the imaging, the fixing solution is applied to the image portion, and the printing durability is up to 20,000 impressions.
Elcography is an electrophotographic method that utilizes an aqueous ink based on an electrochemical reaction. When the first page is imprinted onto the roll paper from the drawing cylinder, the next new page is traced to another place on the image cylinder, so that dynamic printing can be completed smoothly. The phenomenon of so-called aqueous ink imaging is caused by a short DC current from the negative electrode. That is, the polymer before the activated negative electrode is forcibly adsorbed by the positive electrode, and a three-dimensional point of a larger thickness and thickness is selectively formed on the surface of the positive electrode according to the use of the needle electrode array. As the ink on the surface of the positive electrode is firmly condensed by the trivalent iron ions, the image formed on the image cylinder can be developed by a squeegee similar to the squeegee used for gravure printing. The developed image was immediately transferred onto paper, dried very quickly at room temperature, and printed long-length, and the developability was also stable.
The wave of digitalization also affects post-press engineering
The wave of digitalization has spread to the post-press engineering today. It can be said that the pre-press, printing and post-press projects with CIP3 as the core have become networked, and have entered the era of managing all the printing projects as work processes. In the paper cutting machine, Heidelberg completed the production of the cutting program by sending the CIP3-PPF data outputted by the digital page number software Signa station to the "computer cutting" of the production program management system through data control. The folding machine also achieves automatic adjustment by means of a computer, which leads to shortening time and labor saving.
The Prima Selective saddle stitching machine from MullerMartini added the option of optional binding on the original machine. After printing by the address of the inkjet until stacking, it is processed online. Based on this, based on customer data, it is possible to bind to different interests, regions, ages, hopes, etc. It can be said that it has entered a new binding era combined with communication media. The Oristar of Zhengrong Machinery Manufacturing Co., Ltd. is a computer folding machine for the digital age. In addition to this, the sewing machine and the gluing machine that respond to the binding according to the ecology are all designed to be multifunctional and to shorten the preparation time in order to meet various needs.
Polyzone is proposing a new post-printing project based on a book-on-demand system and a processing system headed by the BQ340X. In addition, the on-demand automatic binding system SP2000DSC of Showa Intelligence Machine is best suited for the binding of multi-variety small batches of printed matter. It is a cutting and receiving table that discharges the A4 paper printer, and is connected to a binding machine that can be used for perfect binding.
Conclusion
According to the above, it can be seen that the digital technology has been targeted at CIP3 and has been penetrated into all aspects of the printing environment. The above is a combination of the digital system of the powerful manufacturers in the United States, Germany, France, Israel and Japan. function. A reference to introduce this technology.
