On-demand color printing can be roughly divided into two types according to the market demand: one is that the color capacity is less than 3,000 copies, the contents of these print products are the same, and the printing time is calculated in days; the other is not large, personalized Very strong, printing time is calculated in hours.
In the two situations mentioned above, the following printing methods are recommended.
The first way: using DTP system color separation laser phototypesetter output film, and then proofing, printing. This method is the shortest printing method with the lowest cost in China.
The second method: scanning, color separation, editing, typesetting using a DTP system, and outputting on any one of a zinc oxide plate, a water-based plate, sulfate paper, or a special film base coated with a hydrophilic layer using a 1200 dpi laser printer Printing plate, the printing plate is directly hung on the small offset printing machine to print the text or image. The advantage is that there is no need for film and less investment. The disadvantage is that the image quality is not high, color images need to be overprinted, and the overprinting of the monochrome offset printer without side and front gauges is not allowed.
The third way is: using a digital printer. This method still requires a scanner or a digital camera to capture the image, and then sends the captured image to a computer for color separation using image processing software (such as Photoshop) and graphic imposition and page design software (such as PageMaker). Editing, retouching, page designing, etc., and then transfer the graphic information to the digital printing press to output the color print. Here are several high-speed, high-quality, high-efficiency digital presses.
1) Manroland Thermosetting DICOweb Press
DICOweb is the first device in Manroland's DICO series of digital presses. It brings with it three new concepts: new imaging technology, variable-format and flat-bed design.
Imaging Technology: DICOweb's imaging management technology enables three fully automated adjustments for imaging, adjustment, and image removal, enabling automated job conversion without printing plates, reducing costs
Platform-style design: In order to maximize flexibility, DICOweb's platform adopts a completely new design. First, the modular structure makes it possible to add new features in the future. The pre-configured interface makes it simpler, faster, and cheaper to add new features than traditional printers. Secondly, Manroland separately processes the software, imaging technology and mechanical parts of the equipment. When it is necessary to upgrade one part of the equipment, there is no need to change other parts.
Variable format: DICOweb uses a sleeve design, roller independent drive and roller bearing linear displacement technology, can change the distance between the drum, through the use of different specifications of the version of the sleeve and the blanket sleeve, easy to complete the print format change.
2) Heidelberg DM9110 digital printing machine The digital design of Heidelberg DM 9110, the open operating platform, the short-cut paper path and the structure of the design principle of the conjugate offset press make it very user-friendly in terms of print quality and operational efficiency. What is unique about DM9110 is:
Excellent image quality: LED distortion-free writing technology, GRET patent grayscale enhancement technology, digital ink writing technology, and a more compact imaging carrier.
· Open data format with a high degree of flexibility and security: Open operating platform can achieve all Windows, MAC platform job printing, digital DM9110 can be compatible with a number of third-party software · Optimized delivery paper design to ensure the printing High-speed operation of production: vacuum suction paper technology, automatic positioning technology, diskless double-sided technology, efficient paper path design, large-capacity paper box, and professional post-press processing capability: Digital DM9110 was considered at the beginning of design. Various special printing needs. There is no decrease in speed when printing A3 format, online printing, online minimum binding, and inserting pages.
3) HP Indigo Digital Press
Platinum Platinum is HP Indigo's newest color digital press that uses Image Tracking technology to achieve up to six color printing, producing high-resolution images and highly uniform tone matching in the field.
Platinum Platinum has the following features:
Use liquid ink. Its small particle size, the formation of more clear and full dot, the image has a high degree of edge sharpness, the ink layer is relatively thin, combined with the paper, can fully reflect the characteristics of different substrates.
Wide color gamut, certified by Pantone, Platinum Platinum offers optional 5th, 6th or even 7th color configurations in addition to CMYK standard four-color inks, providing white, fluorescent and other spot color inks.
· Can adapt to more types of substrates: coated paper, offset paper, stickers, transparencies, plastic film and so on.
Platinum Platinum adopts ITT laser imaging technology. The core of ITT technology mainly includes two aspects: First, the laser that describes the image is increased from four to twelve. The laser density used to form the image is increased, and the resulting image is clearer. The accuracy is also higher; the second is to improve the accuracy of the laser scanning dynamic control, and the scanning speed of the image can accurately match the rotation speed of the imaging drum.
4) Fuji Xerox Docucolor 2060
The Docucolor 2060 is a new generation of digital presses from Fuji Xerox using the Fiery EX2000d raster image processor (RIP), an accurate register system, TRACS (toner copy auto-tuning) technology, trickle-add development technology and patented digital imaging. Leather and BeltNip fixing technology, output at 60 pages per minute. The Docucolor 2060 color digital printing system not only shortens document production time, but also comes with an optional large-capacity paper tray and full configuration of large-capacity stacks. The Docucolor 2060 can run automatically for hours without a duty.
The Docucolor 2060 has a wide range of paper handling capabilities, capable of handling 64-280 g/m2 paper and super large format (320*488 mm) paper, producing full-bleed color documents.
It is worth mentioning that the quality of the Docucolor 2060 color digital printing system is almost comparable to offset printing.
5) Océ DS8000 series products 100-star Océ digital printing products provide users with typesetting, printing, cutting, and binding automatic assembly lines. The DS8000 can be used for stand-alone or dual-sided duplex or single-side printing, and can also be double-colored for overprinting. Its printing speed is 290/470/700 pages per minute A4 format. With continuous print speed upgrade feature to adapt to the user's continuous business development, the company uses the world's leading laser imaging technology (LED PLUS patent protection), also has a unique built-in environmental protection system, continuous supply of non-stop consumables, low printing cost and other unique features. Prisma POD data processing system has superior performance in the dynamic layout of electronic data, personalized production, and networked on-demand printing.
The fourth way: Use a color laser printer with a price of around 50,000 yuan. It is basically the same as the principle of the structure of the color laser printer, but the printing speed and quality are slightly different, so the color laser printer can be used as office and printing industry.
This printing method is suitable for color products with low investment and fast effect. For products with small print and strong individuality, such as color business cards, wedding invitations, color manuals, and product descriptions, etc., they have good economic benefits and can be recovered in a very short time.
