Near-neutral calibration tool allows different output devices to calibrate to a common visual appearance
Heidelberg USA unveiled its near-neutral calibration tool, scheduled for release later this year, at the 2008 IPA Technical Conference in Chicago, which was held April 22-24. The new functionality, based on open ICC standards, will enable different output devices to calibrate to a common visual appearance-giving customers consistent color from any press. The traditional way of calibrating is to pick a dot gain target and calibrate to a dot. The new near-neutral utility uses profiles or user-defined reference values to calibrate directly to the neutral tone characteristics of the reference profile itself, meaning the greatest possible color accuracy. Near-neutral calibration works by comparing a profile made from an uncalibrated press sheet to a known reference (or standard) profile, then calculating appropriate plate calibration curves to create the neutral ramp. According to the company, one of the great strengths of near neutral is the ability to use an industry-standard reference file, or for users to create custom reference files based on their own unique printing conditions. It’s much easier to calibrate using one common profile for different presses or output devices. Dot gain calibration does not always equate to a common visual appearance on different presses. The near-neutral tool will allow customers to easily calibrate to the industry standard profile or other reference file of their choosing.
New solventless laminating adhesive optimizes process speeds
The new flexible packaging laminating adhesive, Solventless Mor-Free L75-164, was designed to meet regulated food packaging requirements in an environmentally responsible way. The product is recommended for general and medium-performance packages, as well as for challenging hot-fill applications. Laminates used in hot-fill applications made with traditional solventless adhesives are typically slow to cure, requiring a week to 10 days storage in inventory before shipping or further processing. The new Mor-Free product attains full cure at ambient temperatures in half the time, typically three days. Converters can also process laminates made with this new Mor-Free laminating adhesive on the same shift-slitting in just four hours instead of waiting a day or more as they do when laminating with competing solventless adhesives.

New machine standardizes monitoring and QC for printers and converters
The FlexiProof 100 and FlexiProof UV can be used by ink, resin, pigment producers, paper, film, foil and other substrate producers, flexo component producers (such as plates and anilox rollers), and by any organization that either supplies or plans to supply products that will be commercially produced on a flexographic press. The compact, bench-top FlexiProof is a scaled-down but component-critical exact version of a flexographic production press, enabling users to improve the predictability of quality. As a color communication tool, the FlexiProof is used by ink producers to trial new products, determining ink/substrate interaction and for batch monitoring (color matching). Printers can use the system to trial new products (pilot runs) off-the-production press, which benefits the printer in that a production press is freed up just for production. Color matching off-press also saves time and reduces press waste.

New roll mover designed for large soft-material rolls
The new Big Wheel RollMover is specifically designed to safely move large rolls of soft nonwoven materials without damaging outer layers. The battery-powered Big Wheel roll mover eliminates the need for cumbersome and hazardous air hoses used to drive other roll moving units. Its 36-volt motor and heavy duty gearbox is suitable for pushing the heaviest of rolls across plant floors or onto trolley conveyors. The Big Wheel uses a larger diameter drive-roller to provide improved contact with the surface of master-sized rolls without creating indents and marks. With its elevated point of contact, this larger roll mover is also less likely to get “pinned” under big rolls at the end of travel. Tapered drive-rollers are also available to keep ends of the drive wheel from marking even the softest materials. Operators control the Big Wheel’s speed using a variable-speed, twist-throttle handle. Throttle response and movement speeds can also be programmed according to customer preference to assure optimum safety in maneuvering large, heavy rolls. Battery operation improves operator safety by eliminating air hoses that create tripping hazards.
