Inkjet Printer Buyers Buying Guide

In recent years, with the media and equipment manufacturers strongly advocating and vigorously promoting inkjet printing technology has emerged in the market, but these inkjet printers are almost all sold to business printing companies, and direct mail customers Almost no such device has been dyed.

In terms of the number of products sold, Pucci Solutions (a joint venture between IBM and Ricoh) is the undisputed leader – they have now sold nearly 200 digital presses to the transactional printing market; This was followed by Kodak. The company's Versamark VL series inkjet printers also achieved remarkable success in the transactional printing market.

From the current point of view, continuous inkjet color printers do not appear to have entered the printing and publishing market; in the field of book printing, only some bookshops wishing to change business models and reduce product inventory with publishing customers will choose inkjet printing. In the area of ​​newspaper printing, only a few international newspapers will use inkjet printers for digital production in small quantities in different countries.

Despite the late start of the ink jet printer, we believe it will speed up the printing and publishing market this year. Since this brings many benefits to users, it is necessary for them to learn how to choose an ink jet printer before making a purchase decision.

Substrates (paper) - Although many equipment manufacturers have stated that their high-speed sheetfed or web-fed ink jet printers can use aqueous inks to print on ordinary offset paper and achieve good quality, they actually use conventional printing. The material will cause the ink to penetrate into the fiber of the paper and continue to spread, which will lead to many problems in the printing process; at present, there are two ways to avoid this situation, one is the use of pre-treatment (invisible coating) Instead of paper, the paper is processed on the press.

The HP T300 press uses the former method; the Fuji JetPress 720 press uses an on-line pre-coating device to process the entire paper before printing.

There are many ways to pre-treat paper. The HP Indigo press uses paper that has been treated with sapphire, and the company's Indigo 4200 and 7200 presses have an in-line pre-coating unit.

The question is which one is better? The cost of paper pre-processing is undoubtedly high, and many publishers are only used to providing paper for printing companies, but they are not willing to pay extra for it. This may seem like a difficult problem to solve, but some researchers have begun to study the ink that can be used on standard offset printing substrates, which will lay the foundation for the widespread use of inkjet printers.

Dyestuffs or Pigments—Inkjet printers use dyes or pigments as the dye, but dye inks are cheaper. In general, dye inks are more suitable for printing more transactional documents, while pigment inks can bring better quality when printing images. Pages printed with dye inks look very flat, but there is the possibility of fading, so this ink is more often used on low-grade uncoated paper such as newsprint.

Water-based or UV-curable inks - At present almost all high-speed printers, whether sheet or web, use water-based inks, with one exception being Agfa's Dotrix. The printer can print on standard substrates with pigmented UV-curable inks. Some people may ask: Why do other equipment manufacturers not use UV curing ink? This mainly has the following reasons: The first is the higher cost of this ink, followed by the general high-speed printing equipment need to use water-based ink. In the not-too-distant future, we may see some new printheads that can be produced with UV-cured ink at a speed of 60 meters per minute, but this printhead is only half as fast as a high-speed aqueous ink print head. Currently, continuous inkjet printers using UV curable inks are mainly used in the label and packaging market.

Print Head - Many people have misunderstandings about the print head and its life cycle. Some printheads, such as the Kyocera printhead on Océ JetStream printers, can use up to 3000 hours; other printheads, such as HP's new Scalable Printing Technology printhead and Kodak STREAM printhead, have a shorter lifetime Something. Long-life printheads are generally more expensive, and their performance can be affected by how the printer is designed. The printheads on the HP T300 printer are replaceable, and the device can be restarted in about 2 minutes; the STREAM printhead on the Kodak Prosper press is also available for manual replacement by the operator; prints from other printers The head must rely on the manufacturer's service engineer to change, but also to stop for a long time.

Click-to-click or not-click-to-pay is a standard business model in the electronic photo market (toner printers). The customer can pay according to both the unit price and the printing quantity that both parties approve, this price includes the service and all consumables expenses, the toner may also include. However, this model is not suitable for the sale of ink jet printers. The selling price of most printing presses is based on the cost of the equipment itself and the after-sales service, while the cost of consumables (including inks and print heads) requires the customer to make a separate payment according to their own usage.

Whether there will be a third-party ink market - in the color toner printer market (including liquid and dry toner), almost all of the toner is supplied by the printer manufacturer. In the SOHO (home office) family of toner and desktop inkjet printers, there are a large number of third-party toner or ink cartridge suppliers. Even in the ultra-large format inkjet market, we can also be a third party ink supplier. The reason why there is a third-party ink market in this area is mainly because the print heads used in all devices are from companies such as Dimati and Xaar.

These companies will test the ink manufacturer's products to see if they are suitable for their own print heads. In the high-speed inkjet market, many equipment manufacturers will purchase print heads from other print head suppliers. Only HP and Kodak have developed their own print heads for their Versamark VL series printers. Epson not only produces printheads for the screens of the Truepress Jet 520 and Infoprint 5000 printers, but also supplies them with matching inks. Many of the ink supplier's products are now certified by companies such as Kyocera and Panasonic, which is likely to lead to a new third-party ink supply market.

The above are some of the important issues that inkjet printer buyers need to understand before making a purchase decision. It is hoped that every printing company can buy satisfactory digital printing equipment.
