Olomouc, Czech Republic – Grapo Technologies, a manufacturer of wide format hybrid and flatbed UV printers based in the Czech Republic will be demonstrating its next generation of printing technology at FESPA 2010, scheduled for June 22-26 in Munich. The new flatbed Gemini X10/1080UV from Grapo Technologies is capable of printing on rigid substrates as well as roll-to-roll, and will bring to market higher speeds, improved quality and a number of new innovations. Grapo Technologies is located in Hall B2, Stand 460 at the show.

“The theme at FESPA 2010 is Catch the New Wave of Innovation,” said Radim Králik, CEO of Grapo Technologies. “That’s exactly what we will be bringing to the show with our next generation platform for UV flatbed printers. With a printing area of 2×3 meter for rigid sheets as well as the ability to handle rolls up to 165 cm, the Gemini X10/1080UV brings tremendous new business potential to sign and display printers at an affordable price point.”

Faster Output, Exceptional Skin Tones
With speeds of up to 90 square meters per hour, the new Gemini X10/1080UV also offers double the speed of previous generation Manta printers when printing with white ink at 15-30 square meters per hour. High quality printing of skin tones and better quality flat colors also differentiate this new printer.

“Sign and display printers are always seeking higher quality to meet the escalating requirements of their customers,” added Králik. “With greater speed and productivity, as well as the wide range of printed products, the Gemini X10/1080UV enables sign and display printers to produce more jobs at higher margins. Much of this new capability is enabled by the 10 XAAR 1001 printing heads with unique Through-Flow system and variable drop sizes for grayscale printing embodied in this new generation printer, as compared to eight printing heads and a fixed drop size in the previous generation.”

Expanded White Ink Capabilities
With the new design, the white ink heads are specifically positioned to print in one pass. “The Gemini X10/1080UV can print CMYK, white and CMYK again, printing three layers all in one pass,” explained Králik. “This is quite unique in the industry and contributes heavily to the improved productivity of this device. This capability is particularly important when printing on transparent substrates, such as acrylics, where images must be displayed on both sides. In addition to using white ink as the diffusion layer for backlit applications for point of purchase and other materials, white ink can also be used as a spot color, allowing selected images to be highlighted for greater effect.”

Grayscale Printing Brings Speed, Quality, Cost Savings
Previous generations of Grapo Technologies’ printers used a binary printing technology with a single drop size. In the Gemini X10/1080UV, grayscale printing is enabled by eight different levels of drop sizes ranging from 6 to 42 picolitres, with extremely precise drop placement. The ability to jet small droplets produces sharp images with smoother gradients and quartertones, while larger droplets produce dense, uniform solids. The result is a near-photographic image quality and also results in more efficient ink consumption, saving up to 35% in ink usage depending upon the application.

This variable drop capability especially affects white ink printing and allows the opportunity to produce more interesting images with much finer detail. The precise drop placement also contributes to both the improved quality and speed of the printer. Grayscale printing can either simulate additional colors, such as light magenta and light cyan, in a CMYK printing process, or additional specialized colors can be utilized if needed.

“We have designed this printer to be even easier to operate and more energy efficient than past generations,” concludes Králik. “It is ideal for screen printers seeking to move to more modern and efficient digital technologies, digital sign printers who wish to move away from less environmentally friendly solvent printing, and for offset or flexo printers who can effectively use the Gemini X10/1080UV to create short run samples cost effectively and/or diversify their offerings. Combined with the broad range of substrates that can be used, from irregularly shaped items, wood and glass to all types of plastic, vinyl and paper materials, the capabilities of the Gemini X10/1080UV relative to its price point are unmatched in the industry. We are excited to see the reaction of FESPA attendees.”

Orders will be taken for the Gemini X10/1080UV at FESPA, which will be commercially available in August 2010.

To achieve targets, to make money, today’s print business needs reasonably fast printer with high quality output on which business can relay 24 hours a day, 7 days a week, 365 days a year.

The New Gemini flatbed UV printer from Grapo Technologies provides all that at affordable price, 2 years warranty and professional experienced service and maintenance support.

Solara ion lamps from Gerber Scientific generate maximum surface temperature of just 85 degrees, which is the reason the system is termed Cold Fire Cure.

The printing world is continually evolving, and so too are wide-format printing systems relying on UV-curable inks. Among the latest technological developments in a field known for swift technological change is the use of LED lamps to cure prints.

How do these LED systems differ from the hot-light solutions currently used? What efficiencies will they bring to wide-format imaging professionals? And are they all essentially the same, or do the LED solutions differ from one manufacturer to another?

We put those questions to a trio of experts in the field, first among them Eric Custer, the technical manager for Summit UV in Columbia City, IN. Summit UV is a newer company that began as an offset, screen, and flexo house that experienced problems with the heat generated by the lamps used to cure UV inks, Custer says.

About five years ago, Summit UV began experimenting on solutions to the problem, and a couple of years later filed its first patent on its high-intensity UV LED curing system. Today, Summit UV sells to printer manufacturers and users internationally.

At the most recent SGIA show, the company unveiled its Black Diamond, a 5-by-8-foot flatbed inkjet printer using Summit UV’s own curing technology, Custer says.

In general, UV LED printers provide a number of advantages, he adds. Those benefits include the fact these printers do not subject substrates to infrared heat, so much thinner film substrates can be used. They also offer long light life, translating to savings of $1,500 every 500 hours on the replacement of mercury arc lamps.

What’s more, they consume less power, requiring just a standard 110-volt household system rather than the 220-volt power and large power supplies consumed by mercury arc lamps. Finally, some mercury arc lamps create ozone, Custer reports. “That means you have to have better ventilation for the work area, and exhaust some of the heat off the lamps,” he says. “With LED, you have no ozone production, so you don’t need that ventilation. And the atmospheric heat generation is very small.”

Summit UV’s LED technology improves on the process used by others, Custer adds. “Ours is a focused light, whereas the conventional LED systems are flat arrays,” he observes. “The geometry of the way we make our light allows for higher curing speeds per line, due to the high power generation.”

Also, the company’s LED technology is based around the 365-nanometer wavelength, which permits many more formulating options for the ink chemist. That in turn allows for accommodation of a greater range of inks, Custer says.

Roland DGA

Andrew Oransky, director of product management for Irvine, CA-based Roland DGA Corp., agrees with Custer about the benefits of using UV LED printers are numerous.

“The lamps consume far less power than traditional UV sources, and as a result are less expensive to run on a daily basis,” Oransky says. “They also run cooler, which allows the use of a wider array of media. Typical UV lamps can get as hot as 1,500 degrees Fahrenheit, and they can warp or distort materials, particularly plastics. In contrast, the LED lamps we are using in the new LEC-300 never reach a temperature of more than 104 degrees, which is roughly the same temperature as warm tap water.”

LED lamps are also an improvement from an environmental standpoint, Oransky says. Not only do they boast lower power consumption and require low maintenance, but their life span is 10 times that of traditional lamps, yielding fewer bulbs in landfills.

The key difference most users will notice in an LED curing printer, he says, is the absence of a shutter mechanism. The mechanism isn’t required because LED lamps can be turned on and off instantly, require no warm up, and don’t have to be left on to prepare for the next curing cycle. This also means that rather than having to wait up to half an hour for the printer to warm up and for you to get the first job out each morning, the printer is up and running as soon as you walk in the door, Oransky says.

“LED lamps emit different wavelengths than traditional lamps, so ink formulation is critical with LED curing,” he adds. “Inks must be designed to cure at the wavelength that the lamps emit. As a result, printer manufacturers need to take a system approach to design and inks. Also, lamps cannot be replaced with generic items.”

The Roland VersaUV LEC-300 Oransky mentions features safe, low-heat LED lamps, and prints CMYK plus white and clear on substrates that include foils, metallic and synthetic papers, BOPP, polyethylene and PET film. It’s “a digital printing device supporting an endless range of highly customized applications,” says Rick Scrimger, vice-president and general manager of Roland DGA Corp. “In addition to short-run production of high-end specialty graphics, the LEC-300 is a uniquely capable prepress tool for label proofs, packaging comps and one-off prototypes.”

Gerber Scientific Products

A different approach to UV LED printing has been advanced by South Windsor, CT-based Gerber Scientific Products, says director of inkjet printing Curt Brey.

“Gerber’s approach is different in both the ink and the light source,” he explains, noting that in the UV curing field, the two approaches used are as different as night and day, black and white and particularly hot and cool. One side features the mercury-vapor lamps, with a contact temperature on the surface of the substrate of 300 to 400 degrees Fahrenheit, and a temperature on the lamp of from 400 to 600 degrees Fahrenheit.

At the other end of the spectrum are LED curing technologies, which Brey says are typically found on higher-end printers of $200,000 or more.

“Gerber has secured the intellectual property to take hold of the space in between those two curing technologies, with high-pressure mercury vapor lamps on one side and LED on the other,” Brey says. “Our technology can only cure our inks. It is neither hot nor inhibited in its life. The high-pressure mercury vapor lamps have a useful life of 500 hours, while ours last thousands of hours.

“We’re the only company we know of today that covers our lamps under the one-year warranty and the service contract. Our lamps simply don’t break down as fast as high-pressure UV lamps. They’re an entirely different type of technology.”

Solara ion lamps from Gerber Scientific generate maximum surface temperature of just 85 degrees, which is the reason the system is termed Cold Fire Cure. At these cooler temperatures, the printer can imprint a wide variety of materials, including heat sensitive materials like paper and biodegradable and recycled signboards, Brey says.

The other attribute of the printer is that it successfully prints with cationic inks. The GerberCat cationic UV ink is specifically formulated to work with the Solara ion. Its features and benefits include adherence to more materials than any other inkjet ink, great resistance to abrasion with unmatched scratch resistance and the largest UV color gamut in the industry, Brey says.

In addition, it is a highly flexible ink that supports vehicle wraps and vehicle graphics applications, offers the greatest chemical resistance of any ink marketed, and is environmentally friendly in that it enables the Solara ion to generate minimal waste.

“GerberCat cationic UV inks have proven to be everything we’d hoped them to be and more. And the Cold Fire technology is offering graphics printing shops more solutions and more applications than we’ve seen from any printing solution to date.”

INX Digital’s TDI intros new high-speed, single-pass UV LED-curing inkjet ink at DRUPA.

INX Digital’s TDI intros new high-speed, single-pass UV LED-curing inkjet ink at DRUPA.
San Leandro, CA – May 21, 2008 — Triangle Digital INX Co. (TDI), a member of INX Digital,
has stepped up the pace in global ink leadership, partnering with LED curing specialist
Summit UV in developing EVOLVE™ UV — the first UV LED-curing ink to deliver eye-popping
4-color with single-pass through-cure at speeds of 80’ per minute or higher, running with
Xaar™ 1001 piezoelectric printheads. All with no inert curing atmosphere.
DRUPA visitors can see the system in action at the INX Digital Exhibit CO2 in Hall 8b, from
May 29 through June 11, 2008 in Dusseldorf, Germany.
“We’ve been working with LED-cure inks for some time,” said Ken Kisner, TDI’s Sr. VP, Chief
Technology Officer, “but at slower speeds. A key to this technology’s success is formulating
EVOLVE UV to work with Summit UV’s unique, new LED. It has the ideal UV wavelength
and, importantly, ample power.”
“Compared to conventional high-intensity LED lights,” explains Mario Carluccio of Summit
UV, “our Black Diamond™ 365 Series has a shorter (365nm) UV-light wavelength and much
higher focused outputs — in excess of 6.0 Watts per cm2.
“This enables us, with TDI’s specially designed EVOLVE UV ink set, to achieve through cure
at far faster speeds than ever before.”

Breakthrough technology opens new avenues for digital growth.
“We’re now breaking barriers to digital printing in several areas,” Kisner points out, “including
short-run narrow web label printing, variable-data applications — and many more to come.
“Getting single-pass UV through cure in-line with one LED light at 80 ft./minute more than
triples previous speeds. And it’s just the beginning. We have the ability to tailor EVOLVE
UV inks for virtually any substrate — plastics, film, paper; even metal or certain textiles.
“We’re integrating technologies to provide high-speed printing at low cost. And, of course,
the standard digital advantages vs. conventional printing apply — faster startups and
turnaround with no plates, no cleanup or setup time.”
“Likewise, versus traditional mercury lamps for UV curing,” Carluccio emphasizes, “our LED
technology dramatically lowers power requirements while offering advantages such as
extremely low heat generation, instant on/off, no bulbs or other consumables. It eliminates
hazardous mercury, and avoids ozone emissions.”
“It’s a ‘double-green’ system,” sums up Kisner. “EVOLVE UV inks are formulated VOC-free.”
Fast, collaborative effort generates ‘buzz’ at RadTech, jump-starts DRUPA debut.
And it’s coming together quickly. Kisner and Carluccio both noted that mere weeks ago, this
combined technology didn’t exist.
Having previously collaborated on development work, INX Digital member TDI responded to
Summit UV’s invitation to test new EVOLVE™ UV inks with its new Black Diamond™ 365 series
LED-curing lights. Another INX Digital member, electronics engineering and system
integration specialist Innovative Solutions INX (ISI) has utilized advanced-generation Xaar
printhead technologies.

“When Mario told us the speeds at which they were getting through cure,” Kisner said, “we
contacted Xaar immediately — only a few weeks before RadTech (UV/EB Technology Expo).
Their Xaar™ 1001 printheads completed the system in time to demo at the recent Expo.”
The high-speed, single-pass UV LED-curing system created quite a stir, Kisner and Carluccio
concur. “Many observers said it was the most innovative system at RadTech this year,” Kisner
asserts, “and we anticipate a lot of interest at DRUPA.
“We’re excited about how far EVOLVE UV LED-curing inks have come so far. And even more
excited about where this technology can take digital printing in the future.”
Triangle Digital INX Co., a member of INX Digital group, is a leading global manufacturer of
inkjet inks for wide format, super-wide and new generation digital printers, and a supplier of
printer parts and related services. TDI also distributes selected advanced-design wide format
printers and recyclable polyethylene (PE) media.
INX Digital, the digital arm of INX International Ink Co., through INX Digital member
companies and global affiliates, offers a full palette of digital ink systems, advanced
technologies and integration services including chemistry, hardware, software, engineering
design & integration and media.
