New BOBST VISIONFOIL 104 H provides ultraprecise hologram application
10 03 2010
BOBST has launched a version of its VISIONFOIL press, specifically dedicated to security hologram application.
As more and more industries look for solutions to protect the authenticity of their products, holographic materials offer an ideal solution, helping its brand owners make a clear difference between originals and forgeries, protecting their valuable assets, and deterring counterfeiters.
However reproducing holograms, and placing them accurately on the product, require specialized equipment. Until 2010, the reference machine for flat-to-flat hologram application on paper, labels, or board has been the BOBST SP 76-BM Foilmaster, a B2 size press (equivalent to a packaging format of 0b). Now BOBST has introduced the VISIONFOIL 104 H to deliver hologram application of accuracy previously unavailable to the B1 print sector or the format 3B packaging market.
The VISIONFOIL 104 H uses BOBST’s patented, high precision Registron cameras to bring each hologram on the sheet into perfect register, be they 2-D, 2-D/2-D, 3-D, 2-D/3-D, or multiplexed. The same cameras perfectly process diffraction foils, skipping the unusable shim line areas. All current sizes of holograms can be processed using the VISIONFOIL 104 H. In addition the press handles holograms substantially larger or smaller than current industry standards - offering designers and users the opportunity to include special size holograms in their designs or portfolio of products.
The smooth foil path created by the specially designed internal foil unwind module, enables high precision foil handling and better productivity. The cameras are auto-setting, reducing make-ready time. Up to six independently driven advance shafts, increase flexibility and cut down on foil waste. The platen entry easily handles light materials which make up the majority of security print jobs.
Alongside its hologram application capabilities, the VISIONFOIL 104 H is highly flexible, being able to apply conventional as well as holographic foil. The press shares with the rest of the VISIONFOIL 104 range a maximum running speed of 7,500 sheets per hour, along with the ability to run paper and labels down to 80 gsm, carton board to 2000 gsm, and corrugated sheets up to 4 mm in thickness. The maximum sheet size the VISIONFOIL 104 H can handle is 1040×740 mm and the press features 12 individually controllable heating zones.
The VISIONFOIL 104 H is ideal for banknote printers applying holograms and/or metal stripes; software packaging manufacturers applying seals to CD/DVD cases; ticket printers producing concert, event and sporting event tickets, tobacco industry suppliers and other industries trying to protect their products or brands.

UK scientists have “tied light in knots”, paving the way for new applications of laser technology. A team of physicists working at the universities of Bristol, Glasgow and Southampton accomplished the seemingly impossible feat using a series of holograms to control the flow of light.
The breakthrough could be used to offer unprecedented levels of precision in sophisticated applications that currently use lasers, such as speed cameras and measurement devices.
The pioneering British team implemented a previously abstract mathematical formula known as “knot theory”, which allowed them to manipulate light into “knots”, providing greater control over the direction and precision of the beam.
The sophisticated hologram design required for the experimental demonstration of the knotted light shows advanced optical control, which undoubtedly can be used in future laser devices.
Speaking on the exciting future of the home grown device, Professor Miles Padgett from Glasgow University, who led the experiments, said: “The sophisticated hologram design required for the experimental demonstration of the knotted light shows advanced optical control, which undoubtedly can be used in future laser devices.”
