Direct imaging equipment and toner equipment

The competition between direct imaging equipment and toner equipment in the color short market is extremely fierce. Although there are many claims about which of the two technologies are more advantageous, both have their own advantages and disadvantages.
Just as in the fierce competition between brothers in any family, the debate in the printing industry that direct imaging printers and toner (with dry powder, liquid, and semi-liquid) equipment has advantages is equally fierce.
In the struggle to win the recognition of customers, the accusations between DI (direct imaging) technology and toner technology are fierce. Both are recognized as being applied to the same short-run, short-run printing market. Since the global short-run printing market is worth millions of pounds, this part of the market is very profitable. As the highly personalized printing market (now dominated by toner technology) fails to meet the expectations of its supporters, the competition between the two technologies is fiercer. The end result is that these technologies are struggling to gain market share in short-run color printing, and suppliers are using the latest four-color printing presses equipped with the latest automatic control devices and laser imaging plates to gain value-added benefits.
Various claims continue to emerge that these two technologies have their merits. First, the toner printer can provide completely personalized settings that are different for each print. Although there have always been legends that the combination of DI (direct imaging) printers and inkjet technology can provide a degree of personalization, DI printers still cannot provide complete personalization. Secondly, toner technology is still limited to double-page previews. Although Xeikon's DCP500D machines can print B2 sheets of paper, HP Indigo has also exhibited B2 format printers at the show.
There are also many hypothetical claims that raise new questions. One of them is that the toner device removes moisture from the paper, making the paper susceptible to cracks. With the advent of newer toner devices such as Xerox's IGen3 and Heidelberg's Nexpress 2100, better quality paper and more regulated conditions have eased this situation. However, DI printers also have the advantage of being able to print on all substrates of offset printing companies.
In comparison, at least for Xerox, the quality of DI printing is not as good as that of traditional printing presses. Again, this view cannot be confirmed, and sample equipment from printer manufacturers does not support this claim.
The major difference between the DI printer and the toner printer is that the DI printer appears to be from a traditional printer manufacturer. As a result, Kat (KBA) B2 and B3 format presses from KBA, Quickmaster DI and Speedmaster DI74 presses from Heidelberg (Hydtberg), Lithrone S40D from Komori, and MAN Roland (Man Roland) Digiweb Press. Other manufacturers such as Adast and Akiyama also consider adopting DI printing technology, and newspaper printing machine maker Wifag will also produce presses equipped with DI units. The toner printers come from companies that were mainly confined to producing office equipment in the past, such as Xerox, Canon, Minolta, etc., or from companies that have just started such businesses, such as Indigo. And Xeikon company. Heidelbeg has also been involved in both types of equipment, including the NexPress series of toner presses and DI presses.
The ultimate victory of this debate will not be the superiority of technology, but the acceptance of the market. At the end of last year, the United States CAP Venture Capital Corporation conducted an accurate and detailed survey on this market share, studying the cost per page and the relative quality of each equipment production. Its ultimate indicator is a machine that prints at 24 pps per minute, but because Xerox's IGen 3 press has not yet been fully marketed, it does not include the cost and equipment cost of a single-page copy.
With various devices using toner engines, as the number of prints increases, the cost of copying a single page remains stable, and the total cost increases in proportion to the number of copies. CAP calculated the cost taking into account factors such as equipment supply, print preparation and manufacturing costs. This constant is the reason for the device's click control, and it also means that the toner printer almost does not need to be ready for printing when performing a color print job. Users who are accustomed to using conventional lithographic printing presses are unaware of this, and are more expensive when printing on paper-intensive Xeikon web presses. In contrast, the single-page copy cost of a DI printer is similar to that of a conventional printer. The larger the print, the lower the cost of copying a single page. CAP identified the inflection point of the cost as approximately 400 sheets. Once this number of impressions is exceeded, the cost of a single-page copy of an offset press is advantageous.
CAP also differed from Xerox in terms of print quality. His evaluation of the 46 Karat press was 10, that of the Indigo press was 9 and that of the IGen 3 press was 8.5.
However, the market is skewed based on the established user base. If a company already has a press and a ctp unit, it is unlikely to invest in DI machines with multiple imaging heads. And a new device for rapid print job preparation or a toner product (providing an additional market competition tool) would be more suitable for companies. This is the argument that KBA used to make for the introduction of the Genius 52 machine. The Genius 52 device has all the features of the 46 Karat machine: short print job preparation, short runs, and waterless print quality, but no DI head. Plates will be produced by the company's existing equipment.
KBA also pointed out that DI printers are not suitable for designing as a unit printer because each printing unit requires an imaging head. Using a common blanket cylinder design on a Karats machine, an imaging device can handle two plates, reducing the cost by half. Therefore, it is conceivable that DI printers are most suitable for places where there are no printing machines, such as prepress or in-house factories. Word & Graphics (an Ansty user of the first 46 Karat device in the United States) is a typical example, and the company has only one Indigo device in addition. The prepress company FM2 in Dublin, Ireland, also has a Karat machine, which is an example of a DI printer suitable for prepress companies.
The cracking between rock and hard ground was also proposed by Xerox. A company spokesperson said: "Now, DI printing is in a crack between rock and hard ground. On the rock side is a traditional press equipped with ctp, which allows printers to receive those short prints. Digital printing, the development of technology is continuously improving the performance of digital printing, thereby reducing the cost of long-run printing."
But there is no doubt that for a traditional printing company, it is problematic to rely solely on "click charges" to control the amount of print payment. Heidelberg has already realized this, and it will no longer impose "jog" controls on its NexPress product line. The company believes that consumables are more durable during use and that the replacement parts are longer than originally thought. Stephen Clarke, managing director of Falcon Press, said that it has been proven that using a Nexpress machine without "jog" control is less expensive than similar devices with this feature.
Although Heidelberg has a unique position in the supply of various technologies, the company's view is also that toner printing is suitable for very short prints, while DI printing is suitable for high quality and short-run printing. “In the increasingly fierce market competition, direct imaging has been squeezed out of the following digital printing, the above traditional small offset printing presses equipped with ctp and high-efficiency production line workflows. We believe that for those prints at 500- DI printing is an excellent solution for four-color standard prints in the 5,000 range."
There is no doubt that digital printing is rapidly swallowing the simple monochromatic and double-page printing markets that are mostly monochromatic. If the typographic printing presses currently on the market are mainly used for monochromatic operations, then a series of online post-processing options are available to make Docutecb and Digimaster devices suitable for short-run book printing and short-run printing. This situation is unlikely to occur in four-color printing, because with the upgrading of digital printing, the traditional offset printing is also upgraded through metal polishing and polishing, the use of special colors, and other such methods. These methods are used for digital printing. It is unrealistic to say.
This will put DI printing in what position? Although DI printing is currently limited to a very narrow environment, it is looking for some heavyweight support. Ryobi is developing a Japanese market that can accept this technology. Bob Usher, co-consulting director of Apex Digital Solutions, said that the debate over the cost of one-page copying has focused on swings between 350-10,000 servings. KPG's sales of DI printers in the North American market have improved, and it is clear that this is an impetus for future media sales. However, Mr. Jack Schloff, president of KPG's global staff, said: "Our users are constantly seeking ways to grow their businesses and increase profits. KPG's DirectPress 5034DI press helps them grasp the business orders they lost today, and can reduce The current production cost of the project."
The simpler and more important point is that the DI press is simple to operate, at least as simple as an anhydrous Karat press. The operation of the DI printing press is now very similar to the offset button technology, minimizing the need for training. Moreover, DI printers have higher controllability than conventional printers, so a plan was established between KBA and Httpint to create a Karats network that can output jobs and remote color correction at the site. To date, this technology cannot be said to have swept the entire printing industry.
DI printing is one of the development directions of the printing industry, although it is not the only one. As traditional offset printing and toner technologies have expanded, both technologies will maintain their market space. Although the shadow of ink-jet printing has only begun to emerge, but as a came into being technology is widely spread in office and home. This gave printing a timely turn, enough to overcome the quality of the controversy.
