Extend the color gamut of UV inks
1. Become a Third Party UV Ink Supplier
The perfect performance of UV inks in printing is not only dependent on the ink itself, but also depends on various factors such as the print head, curing lamp, etc. It should be said that the results are produced simultaneously. At present, most UV inks are still supplied by UV printing equipment manufacturers, although companies like Sun Chemicals, Hilord, and Triangle Digital, as independent third-party UV ink suppliers, have begun to provide UV ink products to specific customers.
2. Add UV ink printing color set
Many UV printing devices only provide the CMYK four-color basic printing color group, and some printing devices are equipped with printing color groups such as light cyan and light red. Other devices have added color groups of orange, green, blue, and purple to expand the color gamut of printing inks.
Raster Printers' 4000 Series UV-curable inks are used on Daytona presses, while the RP-720UV printing machine adds an orange and blue color set to the CMYK four-color base color set. Gantinovations' Jeti 5024 UVRTR, as well as some Eastech Octra devices, offer orange and green color groups, while the Gerber Solara UV2 printer offers green and purple color groups.
In fact, for most UV printing devices, the most increased is the white color group. White ink can be used not only as a primer before printing but also directly for the printing of printed white texts.
Durst's Waters believes that the rapid growth of white ink demand is a matter of course, because white ink can meet more customer needs, such as more visual effects, more abundant business applications. Only inexpensive and simple UV curing can be used to print on almost any substrate.
Other UV printing equipment suppliers, such as Lüscher and Eastech, provide personalized spot color services to provide customers with personalized UV color printing group matching services. Although this service requires strict and high costs, The customer is very interested in this service.
Roger Walkley, inkjet product manager at Inca Digital Printers, said adding the spot color printing group is still a very large project at present, because the CMYK four-color color group is currently used for printing.
3. Development of Varnish
Varnish is also another emerging paint that is often formulated in UV printing. It not only expands the color gamut of ink, but also expands spot colors and white areas, helping UV-printed products compete with screen printing and offset printing.
4. The openness of UV ink technology
Walkley believes that the successful printing solution should be in terms of ink application flexibility. Compared with traditional solvent inks, UV inks have no obvious advantage. Because of the multi-polymerization (UV inks undergo photo-resin curing process) effects, inks Flexible handling after printing is very difficult, and only in the vacuum state can reduce the tension, so that the ink surface is sturdy. Therefore, whether the ink is flexible in the application process has become an important point.
According to Tony Fulco, a market development consultant for 3M Imaging's product center, “Whatever the traditional printing method or digital printing, the secret to success is to ensure the maximum possible openness of UV ink technology.â€
Recently, 3M Multi-Purpose UV-curable Piezo Inkjet Ink Series 2700UV inks, jointly developed by Durst and 3M, are used in conjunction with Durst's Rho 160R Inkjet Press, equipped with a 62-inch round cylinder, which can be used in 3M. Good UV printing on inks and substrates. At the same time, 3M also launched its 2200 series of UV-curable inks for EFI VUTEk UV inkjet printing equipment.
Aellora Digital has been searching for hybrid UV semi-solid inks for its special UV printing equipment. The particularity of this ink is that the ink that is ejected is very hot and will become very viscous when contacted with printing materials, which makes each The drops must be very precise and do not shift. This eliminates the need for immediate full cure even when printing on porous or non-porous substrates. “When we use this ink, even if the ink is not completely conjunctiva dried, the droplets will not expand or cause splashes.†Aellora Mike Stoudt, president of Digital, said.
Long-term printing experience makes inkjet printers interested in single-channel inkjet printers. However, many printing companies prefer multi-channel inkjet printing that can store more ink and meet the needs of a variety of printing businesses. But from now on, the guardians of single-channel inkjet printing decided to change this situation.
Inca FastJet is a strong advocate of single-channel inkjet printing. As early as drupa 2004, Inca FastJet introduced an inkjet printing device with a resolution of 300 dpi. This device can output super large-format printing jobs per minute. With fixed-mounted or dot matrix nozzles, the printing material passes under the print head, and the ink ejected at a time can completely cover the entire printing job.
Aellora Digital offers a full range of solutions for single-channel printing. The company offers semi-solid inks. The SureFire TKMP1000 digital printing system can achieve a print speed of 250m2/h at 600 dpi x 600 dpi.
