Introduction to mainstream digital print Banner Stands

Written by Trade Show Table Cover wholesaler on 29 April 2012. Posted in Banner Stands

Digital print, in broad terms, all connected to the computer, without plate can direct print devices are known as digital printing. Special digital printing, is the use of prepress systems on graphic information transmitted over the network directly to the digital press, a new printing technology to print out color prints. Several now mainstream digital printing technology is mainly electrostatic ink jet imaging, imaging, magnetic imaging, direct imaging (DI), and cemented like technology.

In short quick print edition today, the digital printing technology has become increasingly popular for Trade Show Banner Stands. Digital printing development in China was not plain sailing, however, still faced many obstacles during the period. Although the trend of digital printing has also gradually mature, but is not high per cent overall printing business in China.

While is due to domestic offset price overall level below digital fast printing, makes digital printing in price and production cycle Shang of advantage no full play out, while digital printing personalized printing of advantage also no full development, many people also is on digital printing of concept more fuzzy; on the, due to digital printing and traditional printing products also is exists must of differences, so caused has people in products identity and printing needs Shang of errors, this also lag has digital printing in in China of development. On the whole, since 2004, digital printing in China is becoming a hot trend, but it is only in its infancy, there is still a lot of people doubt and confusion about it. This paper describes several leading digital printing technologies now in order to let more people know about the digital printing technology.

Several leading Trade Show Banner digital printing technology

(1) Ink-Jet (Ink-jet) imaging-digital Trade Show Banner printing

Inkjet printing is means will ink to must of speed from micro-of nozzle shot to printer real Shang, and by ink and printer real of mutual role implementation ink image reproduction, its Imaging principle is will ink to must of speed from micro-of nozzle (General diameter in 30~50 μ m) Jet to printer real Shang, last by ink and printer real of mutual role implementation ink image of reproduction. General requirements for solvents in the inks, water to rapid infiltration of printing, in order to ensure adequate drying speed, requires the coloring agent in the ink of solid printing surface as much as possible, to ensure sufficiently high print density and resolution. Therefore, the inks used must match the printer in order to ensure good print quality. Early devices to continuous inkjet, ink nozzles according to certain rules continue to drop, if the ink drops not printed on paper, then pop open in a static manner, recovery to the ink tank. In this way because the efficiency is not high, after the development of on-demand ink technology drops, ink-jet head to place drops of ink you want to print. Because the ink-jet head to replace, mass production of many manufacturers, replacement and price benefit, ink-inkjet printing equipment to drop on demand technology, and continuous ink-jet ink-jet head, must be manufactured by printer manufacturers as a whole has always been, is not universal. In the field of inkjet printing, most inkjet printers to color image to the output terminal of the personal computer, is not too high demands on quality and speed, but convenient, maintenance-free, the price is cheap.

Large format inkjet printing technology is mainly used in the fields of digital proofing and printing for Trade Show Banners, the major manufacturers such as Epson, HP, Kodak, Roland. In digital proofing area, inkjet printing to its quality advantage, has replaced offset plate proofing, and hot transfer proofing of trend; in digital printing area, main is electrostatic photography (color powder) and inkjet Imaging two a mainstream system, main should for variable data printing, and publications, and personality sample, and direct mail printing, and commercial printing, and label printing, and trademark printing, even security printing, special area; in sharply surface inkjet area, currently all indoor outdoor show, and advertising, and poster, sharply surface printing main by network printing, and Offset and inkjet Imaging 3 ways making, screen printing is more suitable for the production of more than 400 businesses, but on the current market, less than 200 leaflets job market demands more, with many varieties, increased small-batch job, the traditional screen printing was very limited in such manner.

Ink-jet printing method, water-based ink-jet and based on a paper of up mainly of the large format inkjet printer market share, but the proportion of solvent-based inks and UV curable inkjet is rapidly expanding, from environmental protection, adaptability of printing, UV curable ink jet is likely to become the mainstream of future market for large format color.

(2) the static image (Xerography) digital Trade Show Banner printing

Static image (Electro-photographic), also known as electronic photography, its basic principle is to use laser scanning method in electrostatic latent image formed on a light conductor, then charged toner and electrostatic latent image visualization of the realization of the Coulomb force between latent image, and finally to transfer toner images to print on the printer.

In the digital printing industry, electrostatic photocopying digital printing technology, far more mature than ink-jet technology, at the same time it is also the most widely used digital device, form one of the most flexible way. Electrostatic photography system in the has two species basic mode, a is used wet type color powder developer of high resolution force system, General used 800dpi of imaging system, main representative products is Indigo company of digital press; another a is used dry type color powder developer of low resolution force system, used of is 600dpi of imaging system, main has Xeikon, and Xerox, and Agfa, and Canon, and Heidelberg, and ManRoland and IBM, company of products.

Overall, the electrostatic printing system more flexible, not subject to volume restrictions, primarily used in on-demand printing and variable data printing market. It not only in commercial printing, printing in China has been applied in the field, is also used in financial, Telecom, insurance, publishing and printing, packaging printing, and other areas.

(3) recording (Magnctography)-digital Trade Show Banner printing

Magnetic records imaging technology and tape of records technology used of is same of records principle, is relies on magnetic materials of magnetic child out magnetic field of role Xia directed arranged, formed magnetic latent shadow, and then using magnetic color powder and magnetic latent shadow Zhijian of magnetic field force of mutual role, completed latent shadow of Visual of, last will magnetic color powder transfer to printer real Shang of a printing way.

Magnetic material is mainly iron oxide magnetic toner used, the material itself has a very deep color, therefore, this method is typically only suitable for making black and white images, not easy to achieve color images. Magnetic recording products are mainly used in securities, lottery tickets, magnetic properties of various financial instruments, business forms, labels and bar code printing, and due to the limitations of its production, the printing is mainly used for black and white images adjustable tone number at the same time it only in a limited range within its comprehensive quality can only offset low level. Compared with the traditional screen printing, due to the particularities of the magnetic recording process, despite its high density, but has certain requirements for toner and printer, and a lack of flexibility.

(4) DI (DirectImage)-digital Trade Show Banner printing

DI digital printing system is essentially an imaging system integrates an offset press plates, made the plates used to print large prints of the same content, graphic information of CTP printing technology to print layout, directly from the computer output on a plate mounted on the press, a complete plate and printing technology. Its like printing and traditional offset printing.

DI print system printing preparation time is short, fast printing (tens of pieces per hour) and characteristic of high printing quality, main location at about 5,000 print runs of printed live. This volume of around 5,000, is too big for other types of digital printing machines, and too small for traditional print. On the premise of ensuring printing quality, it can significantly increase printing speed, but also has advantages of offset printing and digital printing.

Its main representatives are Heidlberg Quickmaster-DI46-4 and Speedmaster-DI, Manroland Web DI digital printing presses Dicoweb, Komori, screens, and other companies also have their respective DI figures press launch.

Although foreign DI printing system is developing very quickly, but in China is not very good, the prevalence of lower equipment utilization. Mainly because DI higher equipment investment cost, whose supplies expensive, such as electrostatic, inkjet, and because of different devices, DI-printing variable data printing is not done, so you need power on the charge.

(5) condensed digital Trade Show Banner printing

Electric coagulation imaging technology of fundamentals is by electrode Zhijian of electric chemical reaction led to ink occurs condensed, to makes ink solid with in Imaging drum surface formed image regional, no occurs electric chemical reaction of blank regional of ink still is liquid state, then by a scraping Board of machinery role, will blank regional of ink scraping to, makes drum surface only left graphic area solid with ink, last by pressure role will solid with in Imaging drum Shang of ink transfer to printer real Shang, to completed entire printing process.

Gel imaging technology can be in a 15 nanosecond pulse width step change, so as to be different at the imaging drum area and thickness of the solid ink to achieve pixel-order-style. This image has no special requirements on printing, ink can be transferred on to a common printer.

Digital printing press representative for the Elcorsy company of electro-coagulation products, its resolution is 400dpi. Imaging of electro-coagulation system similar to traditional offset printing, image on plain paper; the use of pigments, different from the previous several digital printing technology, a wide range of tone can be adjusted, can achieve more value ranges, can basically achieve the medium level of offset printing.

3. development prospects of digital printing

Digital printing is high-tech printing technology developed in the 1990 of the 20th century. Since 1993 Israel and Indigo company Belgium Xeikon after the company introduced its first color digital printing press, there have been an increasing number of large multinational companies to launch digital printing, digital printing technologies has developed a more mature. Digital printing in Europe and the rapid development in recent years. Printing presses in the traditional areas of production and leads Germany Manroland and KBA companies also launched a digital printing machine series products, world famous large printing machine manufacturers have entered the digital printing, which reflects the future of digital printing technology has broad prospects for development.

Short version of the development trend of printing industry, variable data printing, and printing industry also introduced the idea of service, is the service concept of a personalized printing. Digital printing technology is different from the traditional way of printing technology, are getting more mature and compelling. While due to digital printing development of is to a new of concept to development of market, and traditional printing business also has nature of difference, so believe as in China printing business towards short version, and fast, and personalized development of area into, digital printing will by virtue of its huge of market potential, gradually reduced production cost, in China of digital printing also will formed industry, and can are rapid of development.
