Rave installs Republic of india'due south starting time Speedmaster CD 102-half-dozen UV plus coater with FoilstarHeidelberg's Foilstar – how its cold foil worksThe cold foil process is no newcomer to the industry of glitz and shine; in fact, it'due south been around in the rotary, narrow-spider web industry for quite some time. However, similar almost technologies, the procedure has become more stable as the technical know-how, equipment, and materials utilized take become more sophisticated. Advancements in consistency, adhesion, substrate compatibility, and speed have opened doors to a broader range of foil applications across a variety of markets – markets that otherwise may never accept considered foil a viable pick.Labels, beverages, cosmetics, sweets boxes, cigarette boxes, magazines, books, greetings cards are some of the applications that tin can exist busy with metal effects on the Foilstar. Photo PSAFlexographic machine manufacturers such as Mark Andy, Nilpeter, and Gallus accept integrated the cold foil process directly into their flexo printing presses. Across the flexographic arena, recent innovations in utilizing the common cold foil process with sheetfed lithography are entering the market as an alternative to metallized board. This offset technology utilizes a tacky adhesive that is applied in the commencement press caput. The foil is then nipped to the adhesive and the carrier stripped abroad leaving the foil covering the board where required.

Heidelberg has developed this procedure which has been available in the globe market for quite some time now although no such unit was installed in Republic of india and then far due to various factors that might include toll and technological and operational challenges for the printers. However, in a major turnaround, Heidelberg India has announced the first installation in India of the FoilStar on a CD 102 vi-colour UV combination press with coater at Rave Packaging's unit in Manesar, Haryana. The 59th installation in the globe and India'due south beginning Heidelberg FoilStar press surely demands some introduction.

Heidelberg'due south FoilStar explained
In dissimilarity to previous effect foil applications, for which a letterpress or flexographic unit is necessary, FoilStar applies the cold foil using 2 conventional offset press units. The first unit prepares an images of where the foil is to be practical using the inking unit and an offset press plate to apply glue either as a spot awarding or to the unabridged sail.

The actual cold foiling mechanism featuring have-up and take-off units for applying the foil is mounted on top of the 2nd print unit. Along with the sheet, the foil is fed into the nip betwixt the blanket and the impression cylinders and applied past pressure to the parts of the printing stock coated with gum. When the bankroll is removed, the metal layer remains on the canvas.

Subsequent overprinting of the foil enables a great variety of color nuances to exist accomplished. The flexibility of varying the number (1 to six) and width of the foil webs enables foil consumption to be precisely adapted to the current job. Web tension in foil take-up and take-off and the individual reel diameters are automatically recorded by sensors and permanently monitored. A further benefit is that both press units can be changed over speedily and are then immediately available for get-go printing.

The unique selling points of the FoilStar as described by Heidelberg are its fast changeovers and quick makereadies along with an interface which is operator friendly, a fact which was seconded by Shiv Bhatnagar, COO of Rave Packaging. He said, "Contrary to expectations and speculation, let me go far articulate that the FoilStar has a very user friendly operation. We are nonetheless not at the optimum level with the machine at this moment both because the press has just been installed and this is a technology which is unique in the land. All the same, in another two to three months nosotros aim to learn all the ropes and tricks involved and we even plan to organize an Open Business firm in that fourth dimension-frame to bear witness the technological progress that this auto has brought in."
