Goss International introduces
new cost-effective solutions

-offers three-page-around printing option and upgraded dryer technology
Apart from environmental concerns, the cost saving has become explicitly crucial factor during the prevailing economic downturn.
To fulfill the requirements of the day in newspaper industry, Goss International always plays the leading role technologically, and their recent contribution to the industry is in form of Triliner technology, a solution that overcomes barriers deterring many newspapers from converting to a more attractive and cost-effective compact format, with three-page-around printing option for newspaper printing; and Ecoset dryer which provides not only considerable cost savings but also environmental benefits. Here’s a brief.

Triliner technology and SuperBerliner folding can produce a traditional-size folded product, with the larger flap covering standard size advertising inserts.

The new Goss Triliner technology converts two- page-around newspaper presses to print three-page-around, allowing publishers to save paper and increase productivity and colour capacity while still maintaining broadsheet sectioning and the ability to accommodate standard-size advertising inserts. Plate cylinders are modified to accommodate a single plate containing three shorter newspaper pages imaged around the circumference. A Goss SuperBerliner folder allows off-center folds, and adjustments can be made to postpress inserting systems to accept the smaller, asymmetrically folded papers. Publishers can modify existing double-circumference presses to produce papers with two-thirds of the previous cutoff. The Triliner technology is also available for new presses. Equipping a press with two folders will provide the versatility to produce both two-around and three-around products by simply varying the number of pages imaged onto the single-around plate.

“Triliner technology offers the convenient, compact size previously reserved for tabloids, while retaining key advantages of the broadsheet format, including multiple sections and premium advertising positions. The unique off-center SuperBerliner folder is vital to this technology, giving the folded product a familiar size and shape while allowing the larger flap to cover standard-size inserts produced on 21-inch presses. With web widths shrinking, Triliner technology also brings cutoffs into a more familiar and pleasing proportion to page widths,” explained John Richards, director of newspaper product management, Goss International.

Triliner technology includes conversion of plate cylinders, unique folding technology and postpress modifications. Plate cylinders are converted to accept one plate around, in place of the existing two plates around. The retrofit can be completed one couple at a time to minimize interruptions of production. The three-page images are all burned onto one plate, improving register and reducing by fifty percent the number of plates to be changed. The one-plate-around approach also delivers the versatility to run both Triliner and conventional cutoff products with the same press, utilizing different folders. The Triliner folder design combines asymmetrical folding, shorter cutoffs and the ability to triple collect. The folder is based on the Goss FPS folder and incorporates features from earlier Goss folders that performed the triple-collect operation. The delivery of products from the folder with the headline up and modifications of inserter pockets allow most postpress operations to accommodate the compact format and the off-center fold.

Converting to Triliner technology saves paper by reducing the cutoff of the finished product by 33.3 percent. Operational advantages accrue in both straight and collect production. In straight operation, each cylinder revolution produces three papers rather than two, with no increase in web speed. “A publisher producing a 22-inch newspaper at 50,000 copies per hour could produce 75,000 papers per hour in a 14.67-inch Triliner format,” conveyed Richards. “That added productivity can shorten the production window, allowing later press starts or earlier finishes, and it could open up time for commercial or contract printing opportunities. And, the added speed could also allow a newspaper to retain its current print window, while producing the full run on fewer presses,” he added.

“The newspaper industry, like many industries today, faces strong competitive pressures. In this scenario, with the new Triliner solution, we continue to demonstrate a commitment to providing new opportunities, both through new press investments and through cost-effective upgrades that extend the competitive lifespan of existing equipment,” says John Richards, director of newspaper product management, Goss International. “A publisher producing a 22-inch newspaper at 50,000 copies per hour could produce 75,000 papers per hour in a 14.67-inch Triliner format,” he explained.

For collect operations using Triliner technology, sections come in breaks of three, rather than two. The Triliner jaw folder collects the three images around the plate cylinder to produce three sections performer, providing fifty percent more section fronts, section backs and panorama center positions. A second advantage, according to Richards, is a 50-percent increase in colour pages without additional towers, due to the fact that all the new sections have colour in the same positions as the original sections.

The Ecoset dryer is based on industry-leading Goss Ecocool technology, with design enhancements that can reduce energy consumption and emissions by fifty percent or more. Key to this advancement is the elimination of the cooling section within the dryer, which traditionally pre-cools the web prior to the chill rolls to reduce solvent condensation. Due to the unique cooling capability of Goss’s small diameter Ecocool chill rollers, the web can move directly from drying to chilling without condensation occurring. Through the Ecobox option, this dryer can deliver further energy-saving benefits providing the opportunity to use thermal energy from dryer exhaust to heat the building and to heat water for various other applications within the facility. In addition to providing ecological benefits, the Ecoset dryer has a smaller footprint and also provides increased productivity over conventional dryers with separate chill sections. Currently available for all web widths between 1460 mm and 2860 mm, it employs state-of-the-art technologies, such as low-maintenance direct drive motors and Simotion controls, web break detection and CLC cameras to ensure proven its performance with an optimized ecological proposition and reduced running costs.

“With a conventional chill stand, condensation is a well-known frequent problem, which means that for certain job types printers need to reduce press speed by up to twenty percent in order to avoid damage to the web. This represents a significant loss in productivity or a reduction in quality,” stated Bas Klaver, product manager at the Goss International facility in Boxmeer, Netherlands where Goss dryers are designed and manufactured, mentioning that the Ecoset dryer can maintain quality at full press speed and with modified silicone applicators, it is also possible to remoisten the web in order to compensate for shrinkage of the web during drying.

With well over 300 installations worldwide, industry acceptance of Goss Ecocool technology is long established. Groundbreaking integration of essential Ecocool components such as the chill section and web remoistening has led to significant improvements in print quality, web dynamics, cost savings and environmental impact. The Ecoset innovations now extend this appeal. Existing Ecocool installations can be upgraded to the new Ecoset concept, so that Ecocool customers can also benefit from this innovation and achieve a significant reduction in their costs of operation.
