Heidelberg Increases the Speed of Its VLF Speedmaster XL Presses by 20% for High-Volume Packaging
Perfect for High-Volume Producers
Heidelberg’s new PSP speed class presses are designed for converters requiring maximum throughput and minimal waste. Key applications include conventional long runs in VLF packaging, e.g., pizza and cereal boxes, frozen foods, confectionery, pet food, and electronics. Superior Overall Equipment Efficiency (OEE), a measure of makeready time, makeready waste, average net production speed and level of utilization, is critical to the success of this business model. By optimizing all of the components of OEE, the Heidelberg Speedmaster XL 145 PSP drives performance to new heights. Calculations confirm that a Heidelberg Speedmaster XL 145 VLF with PSP package, working three shifts per day, six days per week, produces twice as many sheets as a 2007 packaging press running at a maximum rated speed of 15,000 sph. The Speedmaster XL 145 with Packaging Speed Performance can produce 70 million or more sheets per year.
Many innovations enable the Speedmaster XL 145/162 to achieve top speeds consistently. These include an updated feeder, improved sheet guidance and a 32-foot delivery optimized with Heidelberg’s patented high-performance dryers. Not only do the Speedmaster XL 145 PSP and XL 162 PSP feature the longest drying sections on the market, but also unique-to-Heidelberg, round air nozzle technology that ensures efficient drying for the coating. The dryers are also equipped with seven slide-in units to ensure smooth production and complete drying at maximum speed.
When print quality is a priority, the high-performance inking and dampening system of the Speedmaster XL 145/XL 162 sets standards in color consistency throughout the run, i.e., the form rollers are smoothly transitioned onto the plate (no bending required), rather than hitting the front bend of the plate, often leading to stripes. Especially at higher machine speeds, Heidelberg’s Prinect Inpress Control spectrophotometric inline measuring and control system provides a major assist for operators by adjusting color and register on the fly.
The Evidence Is In
One year ago, key innovations on Heidelberg’s Speedmaster XL 145/162 VLF press series platform were recognized with the 2013 InterTech Technology Award from Printing Industries of America—the first press ever in the 57”/64” class to be so honored. Heidelberg became the U.S. market leader in VLF packaging presses for the first time in 2014, and has sold multiple Speedmaster VLF XL 145/162 models with the new PSP option to demanding customers in three U.S. locations to date this year.
Since the start of series production in 2009, more than 100 VLF Speedmaster XL 145/162 presses have been sold worldwide. Some 70 percent of these are used in package printing. Exacting customers in North America and abroad also have placed multiple repeat orders for Heidelberg’s VLF XL presses after seeing their initial investment exceed expectations in terms of availability, capacity and print quality. Currently, Heidelberg is recording the highest volume of orders since the start of production.
Rand Graphics of Wichita, KS, to Add a Six-Color, 41″ KBA Rapida 105 Sheetfed Offset Press in the Fall
“The key to our success has been the ability to be flexible and offer our customers exactly what they need,” said Randy Vautravers, president of Rand Graphics. “What differentiates us is the ability to print on non-standard substrates with a combination of litho, screen and digital presses. We print on plastics, vinyls, rigid vinyls, PRV, PETG, and other unique substrates in addition to conventional papers. Our existing KBA Rapida 205 provides us with the ability to litho print up to 59×81″ on a variety of substrates, especially plastic. Seeing the quality and speed of our existing KBA press made it an easy decision for us to add a new 41″ model for additional work. We’re trading in an older non-KBA model for this new KBA Rapida 105 press.”
Rand installed its first KBA press—a five-color, 81″ Rapida 205 sheetfed press with coater, the largest press model in the world—in June 2011. That press gave Rand the opportunity to create new work and an opportunity to gain in efficiency, faster throughput, and flexibility while making Rand one of the few printers in the country with the award-winning press, Vautravers noted at the time. Since its installation, the Rapida 205 has provided significant benefits, making Rand much more efficient, significantly reducing its makeready, increase its speed, reduce spoilage, and allowing the company to produce and output more jobs.
KBA Introduces VariDry LED-UV Sheetfed Press Drying Technology
- Very low-energy costs to power LED-UV; a savings of up to 50 percent in power consumption and energy costs vs. conventional UV dryers
- No heat on the printed sheet, thus eliminating distortion of plastic substrates
- No spray powders or other chemicals
- Yields more than 15 times the lifespan of conventional lamps
- Flexibility to easily move LED-UV lamps interchangeably on press depending on job printing applications
- Inks can be cured at up to 340 percent total coverage at standard densities
- All stock types can be utilized including gloss and matte coated papers, uncoated offset papers, paperboard for packaging, non-porous synthetic papers, foil-laminated sheets and plastics such as lenticular, as well as most plastic packaging, card and label stocks
- Environmental and safety benefits; UV, HUV, HR-UV or LE UV all rely on mercury lamps; LED eliminates the risk of mercury or ozone contamination and is 100 percent compliant with future bans on mercury for human safety
“We are the only large-format press manufacturer that can offer LED hybrid presses using both traditional UV and LED-UV processes,” said Chris Travis, KBA director of technology. At Drupa 2012, the company demonstrated LED-UV drying on a Rapida 106 41″ press—the first and only press manufacturer to do so. Today, it can offer LED-UV presses on all formats with or without traditional UV capability. “We also offer traditional UV presses that are LED-UV-ready,” Travis continued. “This means that when a printer wants to switch to LED or complement a traditional UV press, it can be easily accomplished with a few modifications since all KBA UV presses are LED-UV ready. This provides our customers with maximum flexibility and future-proofs their investment.” The KBA VariLED LED-UV system is fully integrated into the press and can be actuated according to the print format. In the future, when running a short sheet, the light-emitting diodes will turn off outside of the sheet.
“We see the immediate future of energy curable presses to be a combination of LED-UV and traditional UV,” remarked Travis. “For example, LED-UV offers a big advantage within the printing units while we will continue to utilize the benefits of traditional UV in the end-of-press dryer to cure coatings. At the Print UV Conference in early March 2014, we had many notable discussions about our technology with interested printers. KBA is at the forefront in this rapidly accelerating transition to LED UV drying as this new technology gains fast acceptance.”
In summer 2014, KBA will be offering live demonstrations of the new VariDry LED-UV curing technology at its customer center in Radebeul, Germany, on presses ranging from Rapida 75, 105, 106 and thereafter on the 145 and is preparing to announce significant LED successes around the world.
