HEATSET WEB PRESSES -- A Heat Wave
Still, another hot-button issue for printers is the need for seamless in-line finishing, remarks Roger Kaughman, manager of marketing administration at King Press.
"Heatset printers, or printers wishing to venture into the heatset market, are looking for more in-line process functions. In the past, our experience has been that the typical customer was seeking a press to simply print and fold magazine or magazine-type signatures printed on a coated stock. But the trend we have seen in the last couple of years is toward the demand for processes like pattern perforating, coatings and spot varnishing to be incorporated into the press system," he reveals. The Process King is his company's flagship press in the commercial heatset web offset market.
Like other manufacturers in this space, Timsons Printing Machinery is also working toward reducing makeready time and waste, according to Steve Kukla, sales manager.
Timsons now offers a wide variety of press models. The new T-48A is an arch press design with semi-automatic plate loading and unloading, which reduces the time needed to perform plate changes. With the
T-48A's consistent makeready time of less than three minutes between plate changes, Kukla says the press has proven to be very beneficial to printers specializing in the short-run marketplace.
Komori America's current web offering is the System 20, an eight-page, (23x20˝) press, which is long grain for compatibility with 40˝ sheetfed presses. It has a maximum speed of 45,000 iph. The cutoff is 23˝ in order to print an 11˝ signature with bleed trim and color bar. It is typically equipped with an automated changeover, combination folder, sheeter and includes many automation features, including individual ink and water tracking curves per color and a CIP4 interface to preset the ink keys.
Soon to be Offered in U.S.
Later this year, Komori—which acquired the web offset press division of Toshiba Machinery in April—plans to introduce the System 38S, a 16-page (23x38˝) press. It was displayed at DRUPA with a European cutoff, and is currently available in Europe and Japan. The System 38S is fully equipped with automated plate changers, automated folder product changeover, ink key preset software, individual ink and water tracking curves, and CIP4 interface.
