Sun Chemical, at the recent ExpoPrint in Brazil, highlighted updates to its family of SunLit sheetfed inks for the commercial-printing market.

The inks are all formulated with what Sun describes as a high proportion of renewable raw materials and each ink is fully aligned with the measures of print standardization ISO 12647:2.
One of the newest products in the ink family SunLit Crystal, which is a universal sheetfed offset process ink. The printing ink can be used on straight or perfecting presses of all sizes and, according to Sun, is a strong product if one or more presses are supplied from a pumping station.

Sun Chemical’s SunLit Triumph Max commercial sheetfed inks, exhibited at ExpoPrint, are formulated for high-speed printing and high-abrasion resistance on a range of stocks. The ink’s abrasion-resistant film is well suited for uncoated and matte stocks, as they dry hard enough to not scuff in finishing operations.
The fast setting properties of SunLit Diamond inks are designed to reduce cylinder build up, cleaning frequency, and sheet guide marking. SunLit Diamond can be used on all offset presses of different sizes and formats. SunLit Exact PSO, meanwhile, is a sheetfed offset ink for high-quality 4-colour process printing. It is suitable for publication, commercial, and package printing.

Heidelberger Druckmaschinen is introducing its new Saphira Low Migration product line of consumables engineered to meet health and safety requirements for food packaging in Europe.

The company focused its range of Saphira Low Migration products for press and postpress, including printing inks, dispersion coatings, dampening solution additives, wash-up solutions, cleaners, oils to protect rollers, and dispersion glues for folding carton manufacture. Saphira Low Migration products are identified with the symbol of a glass and fork on the label.

All materials bearing thjis Saphira Low Migration label are tested by independent institutes for legal conformity with European Regulation No. 1935/2004. The products, according to Heidelberg, ensure that neither the smell nor taste of the foodstuffs is affected, and that their composition does not change in any way.

"With Saphira Low Migration, we are responding to requests from many of our customers for consumables for the food packaging sector that are not harmful to health but are still of very high quality," stated Peter Tix, head of consumables at Heidelberg. "Users can rest assured that these products fulfill all the legal requirements for this sector and thus eliminate one of the biggest risk factors in the production process for food packaging."

Presstek, at the Ipex 2014 exhibition that took place from March 24 to 28 in London, UK, introduced its new thermal offset Zahara printing plate for waterless press platforms.

With no cover film to remove, Presstek describes Zahara as a chemistry-free CTP plate. It can be imaged on any 830 nm thermal platesetter. The plate itself can be cleaned in a processor with chemicals, but Presstek points out Zahara technology also allows users to rinse it with tap water in a traditional processing device, without the need for mechanical adjustments.

“Zahara is UV compatible, perfect for the production of plastic gift cards or credit cards, for example,” stated Yuval Dubois, Product Marketing Manager for Presstek’s waterless market segment. “Zahara is engineered for the industry’s small-, half- and mid-size sheetfed and narrow web label presses.”

Presstek feels that waterless press owners will appreciate that Zahara provides a choice and that it easily accommodates their existing workflow with no mechanical adjustments to their existing processor unit. With the Presstek Zahara plate, just simply image, rinse, and print for a true chemistry-free workflow.

Heidelberg introduced a new series of Saphira inks, called Saphira Ink Low Energy UV 100 and 400, for use within low-energy curing, as well as new Saphira consumables for environmentally progressive printing.

The new ink products are being brought to market to work with Heidelberg’s DryStar LE (Low Energy) UV drying technology, which was unveiled at the drupa 2012 exhibition in Germany. Heidelberg explains its DryStar process leverages highly reactive UV inks, which reduces the number of dryer lamps required in the press to cut energy consumption.

The Saphira Ink Low Energy UV 100 and 400 inks are suited for printing on paper, cardboard, and non-absorbent materials. Both products enable printing to ISO 12647-2 (process standard for offset printing). Heidelberg also provides Saphira consumables like blankets, coatings, washup and dampening solutions that can be employed within LE UV production.

Just before this new ink launch, Heidelberg also enhanced its Saphira Eco product line, first introduced in 2011, to meet what the company describes as "the strictest criteria in the print media industry for the environmental compatibility of consumables."

Working closely with suppliers, Heidelberg states it has defined and introduced the world’s first criteria for environmentally progressive blankets with the Saphira Blanket Pro 200. Heidelberg is also launching the mineral oil-free Saphira Ink Anicolor S100 and H100 ink series for Anicolor technology, which already provides for minimal waste and low energy consumption.

In the postpress sector, users will be able to use Saphira Binding Glue PUR 330 NE, which Heidelberg describes as the first PUR glue not to release any harmful isocyanates.

"Green printing has already become standard at numerous companies in industrialized markets,” stated Peter Tix, head of consumables at Heidelberg. “The Saphira Eco product line from Heidelberg offers these companies a range that meets the world’s strictest requirements for eco-friendly consumables.”

Flint Group today released its PremoCorr series of packaging inks for paper and board applications.

The PremoCorr series, according to Flint, are low maintenance inks for all three levels of the post-print corrugated market. The company explains this statement is based on PremoCorr’s building block resin technology for all three corrugated levels that use modifying blocks to obtain desired characteristics.

Flint continues to explain how Building Block Technology reduces supply chain complexity, improves inventory control, and provides a thorough understanding of the chemistry for every formulation. PremoCorr inks, therefore, eliminate the need for the addition of amines to maintain viscosity. The result is what Flint describes PremoCorr as a maintenance-free ink with a stable viscosity over a wide pH range.

“The viscosity stable, low maintenance benefit of PremoCorr is the result of a scientific statistical approach to the design of PremoCorr and extensive market research,” stated Gayle Wirthwine, Product Development Specialist with Flint. “These inks are a result of many focused man hours – we had to find just the right ingredients to create a formulation that would deliver the best print results.”

PremoCorr inks can be prepared to match accepted colour standards as a blended ink or as part of a dispenser package for corrugated printers.

Kodak advanced its line of Sonora XP process-free plates to be more applicable in larger commercial printing operations, expanding upon the product’s previous fit primarily with small- and medium-sized printers. 

Sonora XP plates are now available in larger widths of up to 1,495 mm and with a 0.40 mm gauge, allowing for their use in more demanding manufacturing environments. The larger process-free plates maintain their abilty to reduce requirements for chemistry, electricity, water and equipment during processing. Kodak plans to start producing even larger plate sizes over the coming months.

“More than 2,000 customers have embraced the process-free revolution started by Kodak," stated Rich Rindo, General Manager of Kodak’s Worldwide Graphics Marketing organization. "The Sonora XP process-free plate is the next step in the evolution of process-free thermal plate technology."

Kodak describes Sonora XP plates as being used in small, medium and large commercial sheetfed operations, as well as with printers running commercial heatset and coldset web presses, offset packaging applications, and short-run UV. Kodak states that its Sonora XP line represents "the only true process-free plates commercially available in [VLF] formats."

Agfa Graphics at its headquarters in Mortsel, Belgium, launched an addition to its ThermoFuse product line of what the company defines as chemistry-free plates.

The new Azura TU, aimed at the commercial sheetfed printers, is a thermal plate product with a rated run length of 150,000 copies or 10,000 in a UV printing environment. Azura TU holds a daylight resistance of up to 48 hours.

The TU plate works with Agfa’s Azura CX clean-out and a pH-neutral gum for cleaning and protection. Azura CX has a bath life of up to 7000 m².

“Switching from a conventional plate to Azura TU means less waste, less disposal costs, less maintenance, and a safer work environment,” stated Dirk Debusscher, Vice President Prepress, Agfa Graphics. “It also equals water savings of more than 95 percent.”

ThermoFuse technology was first introduced around a decade ago, which, in addition to Azura TU, forms the imaging foundation for Agfa’s Azura TS, Azura Vi, Amigo TS and N94-VCF plates.

Van Son Holland Ink Corporation has expanded its line of Wide Format line to include Canon and HP products. Its inks also serve Epson, Mimaki, Roland, and Mutoh owners.

“We are excited about the response we have received in the market for our wide format inkjet inks,” said Paul Fedorys, Business Development Manager for the Wide Format Division of Van Son. “Due to the high demand for wide format we will be expanding our line to include ink for HP and Canon wide format printers.”

The company first launched a line of wide format premium inkjet inks in September 2011, encompassing solvent, dye inks and dye sublimation inks. It added a new line of Grand Format inks this past September at PRINT 13. The inks are available in both cartridge and bulk packaging formats.

Sun Chemical introduced new SunVisto Advantage HS inks for use on corrugated stocks, based on what the company describes as delivering both the print quality and the pH stability required for this printing segment.

“Brand owners are increasingly demanding higher graphic quality on standard corrugated linerboards,” stated Tony Renzi, VP of Product Management Packaging Inks, North American Inks, Sun Chemical. “With the new SunVisto Advantage HS, converters can achieve excellent print quality for their customers while also improving their internal pressroom productivity as fewer adjustments to pH levels need to be made during long runs.”
SunVisto Advantage HS inks are designed to work with higher-line aniloxes and, according to the company, eliminate the need for special GCMI colour matches when added strength is required to hit GCMI colour targets. Sun Chemical also states its Advantage HS inks are 40 to 50 percent stronger than most conventional mid-grade GCMI inks.
Sun Chemcial continues to explain how SunVisto Advantage HS inks eliminate the need to control pH during long press runs, whereas most water-based inks will lose pH and ultimately lead to dirty print and ink build-up if not properly monitored.

The new ink set is designed to produce mid-level to high-end graphics with most paper stock, working with both single and multi-colour jobs on standard corrugated linerboards.

Sun Chemical at Labelexpo has launched three new products: Two new UV white inks known as SolarFlex Neutron White and SolarFlex Sleeve High Opacity White, as well as a new range of EtiJet low migration inks by SunJet.

SolarFlex Neutron White is a high opacity UV flexo white ink, which according to the company, outperforms competitors in terms of opacity, printability and gloss. It is designed for the production of labels, tags, sleeves and other narrow web applications.

SolarFlex Sleeve Opacity White allows customers to match opacity with other UV flexo sleeve whites, but at a lower film weight. It is a UV flexo last-down ink intended for reverse printing of shrink sleeves and other impervious substrates where high opacity is required, including wrap-around labels, clear, paper or board substrates and other film applications.

SunJet, Sun Chemical's global inkjet division, will present EtiJet inks for general label products as well as a new low migration ink technology: EtiJet ULM inkjet. The Low migration UV ink technology is Eupia, Swiss Ordinance and Nestlé compliant.

Van Son has announced it will be launching its line of Grand Format inks at Print 13 next month in Chicago. The product will be an alternative to OEM inks from vendors such as VUTEk, Durst, Agfa, and HP.

According to John Sammis, President of Van Son Ink, the line was created “in response to the demand in the marketplace for an economical, high quality alternative to major printer manufacturer’s ink.”

The Grand Format line will cover  LED, UV curable, and Eco-solvent based inks. The company also claims that the inks will “outshine the quality of traditional OEM manufactured inks due to their unique formulations.”

The company says the new inkjet inks will achieve 80 percent of Pantone colours and features a clog-free formula which the company says will save users as much as half a litre of ink per day.
Van Son was founded in Holland in 1872 and has since become a major supplier of ink and pressroom supplies around the world. 

At the ISA Sign Expo in Las Vegas, EFI exhibited six existing machines in its wide-format inkjet portfolio, as well as the company’s first inkjet inks for thermoforming and corrugated-plastic applications. EFI also introduced new 3M MCS warranty-certified inks for VUTEk GS Pro series printers and offered technology demonstrations of its upcoming SmartSign Analytics software.

Hardware and inks
EFI’s line up of wide-format, UV-based inkjet systems at ISA included: VUTEk HS100 Pro; VUTEk QS2 Pro, a 2-meter hybrid printer with variable-drop grayscale and white-ink print capabilities; VUTEk GS2000LX Pro, a LED UV-curing machine with grayscale and white ink; VUTEk GS3250r, a 3.2-metre roll-to-roll printer with 1,000 dpi capabilities; R3225, an entry-level roll-to-roll printer; and the entry-level hybrid H652 printer.

At ISA, EFI provided printed samples of its new thermoforming inks that can be used to produce thermoplastic sheets for forming into custom signs, POP displays, vending/gaming panels and like applications. The process is based on a patented eight-colour ink system, with white-printing capabilities. According to EFI, the thermoforming inks are designed to help users eliminate costs associated with screen printing, hand-painting and vinyl lettering in thermoformed object decoration. The inks can be employed through specially modified versions of EFI's GS Pro models, including the VUTEk GS3250 Pro-TF and GS2000 Pro-TF.
EFI also introduced new inks for corrugated plastic printing. Designed to solve inkjet adhesion problems in applications like yard signs, these inks, according to EFI, are compatible with all brands of white corrugated polypropylene and will run on the VUTEk GS2000 Pro-CP and GS3250 Pro-CP printers.

At the Las Vegas Sign Expo, EFI announced a new VUTEk GS 3M Premium UV inks for its VUTEk GS Pro series printers. These inks carry the 3M MCS Warranty, which covers lifetime issues of graphics like fading, cracking and peeling. Co-branded EFI and 3M inks for the VUTEk GS2000, GS3200, GS3250, GS3250r, GS5000r and EFI R3225 printers all qualify for the warranty, which is also to be made available for the VUTEk GS2000LX and GS3250LX LED UV-curing printers in the near future.

SmartSign Analytics
EFI’s primary product introduction at ISA was SmartSign Analytics (SSA), which is scheduled to enter beta-testing this quarter. The company describes SSA as software that captures and reports analytic data on signage viewership to help marketers measure campaign effectiveness. “Print can drive relevance, revenue and profit in the age of big data, and this technology demonstration can show how that will happen with signage,” stated Mark McGowan, Director of EFI Online Product Solutions.

A single SSA unit includes a Webcam attached to a sign, connected to a computer or tablet running third-party facial recognition software and EFI’s proprietary SSA software for data organization and reporting. In a retail implementation, EFI believes most marketers will likely deploy multiple units to measure, compare and improve signage performance at different stores or at different in-store locations.
The SSA system’s Webcam and software combination detects the presence of people within viewing range and determines which of them are actually looking at a sign. Eye-tracking tools on the SSA system also allow it to calculate how much time is spent viewing signage. Facial pattern algorithms are designed to assign a gender and age range to each viewer.

Continuing in the software category, EFI exhibited its new Version 5 of Fiery XF with Web Control Center digital front end with colour management, as well as its range of Management Information System software like PrintSmith Vision and Pace.

MacDermid Printing Solutions announced the commercial introduction of a new digital flexo plate specifically designed for use with UV inks. Dubbed the UVR plate, it is swell-resistant to aggressive UV inks and has low dot gain.

According to MacDermid, the 55 durometer plate is ideal for the narrow web market where UV is used heavily. UVR plates can be processed with conventional solvents or in MacDermid’s LAVA thermal platemaking system. The plate is also compatible with the company’s LUX platemaking process, which allows for smaller printed dots and more durability on-press. According to the company, the UVR plate also has comparable performance when paired with water-based inks as well.

UVR is commercially available in thicknesses of 0.045 in. (1.14mm)  and 0.067 in (1.70mm), and in format sizes up to 52 x 80 inches (1,321 x 2,032 mm).

The Dutch appellate court at The Hague has confirmed infringement by Chengdu Xingraphics Co. Ltd. of China with regard to Agfa Graphics NV’s key patent on digital printing plates.

The appeals court decided that Agfa’s patent EP823327 is infringed by the sales of Xingraphics’ FIT digital printing plates. The verdict from the court in the Netherlands is consistent with the first instance decision of November 22, 2011, in a parallel procedure before the German Landgericht.

The court has ordered Xingraphics and its Dutch dealer Atécé to refrain from further infringement in the Netherlands and to pay damages, as well as a refund of legal expenses to Agfa Graphics.

“This court decision confirms that we have a strong patent portfolio and that our IP rights are well founded and relevant,” said Stefaan Vanhooren, President of Agfa Graphics. “It signals that we are serious about protecting our know-how against infringements.”

The injunction against further infringement not only applies to the mentioned FIT plates but also to any other positive thermal plates, which use the patented technology.

‘’We are currently discussing patent issues with other competitors and their dealers in order to obtain a fair settlement as compensation for their infringement," said Rudi Goedeweeck, Agfa’s General Manager of Intellectual Property.

Flint Group has launched a new offset UV ink series aimed at the folding carton and commercial printing markets. Known as the Arrowstar Plus UV8000, the inks are designed for high-speed sheetfed operations.

“Arrowstar Plus UV inks are extremely fast-curing, making them a great choice for print jobs that involve direct finishing, backside printing for non-food applications, and more,” said Tyler Newsom, Sheetfed Product Manager. “Their performance and quality are unwavering, even on the most challenging, high-speed presses in the market.”

Flint says the key behind the Arrowstar Plus UV8000 is the unique resin and photoinitiator chemistry, which leads to exception rub-resistance, among other qualities. “Arrowstar Plus UV 8000 inks use the latest raw material technology to push the limits of cure speed and functionality,” said Rodney Balmer, Flint Group’s Director of Global Research & Product Development, Sheetfed.
