LINCOLNSHIRE, Ill. -- Since its introduction in 2002, the Diamond 3000TP Tandem Perfector has been acclaimed for features that precisely match printers' needs. This now includes the ability to apply aqueous or ultraviolet (UV) coatings to the front and reverse sides of a sheet in one pass. The Tandem Perfector, a 40-inch press available with up to 12 printing units, is the only press that enables one-pass printing of both sides without tumbling the sheet after one side has been fully printed. Mitsubishi introduced two-sided printing and coating to the marketplace with the Diamond 3000R Double Diamond convertible perfector. The double-coater version of the Tandem Perfector features tower coaters before and after the Translink unit. The Translink is a three-cylinder transfer system that passes backside printed sheets to the front-side units without flipping the sheets. In addition to conventional inks and aqueous coatings, the coating configurations and available drying packages for the Tandem Perfector provide great flexibility in the job mix, such as spot UV coatings, UV inks or hybrid UV inks. The Translink unit can be fitted with UV or infrared dryers. The double coaters on the Tandem Perfector enable the press to accommodate aqueous-over-aqueous coatings, UV and aqueous coatings on either side of printed sheets or UV-over-UV applications. Customers can see the double coaters on the Tandem Perfector in action at the Mitsubishi Demonstration Center in Lincolnshire, Ill. A four-over-four Tandem Perfector on-site currently incorporates double coating units.
