The new edition of Stora Enso’s Gallop inline carton printing line has an integrated inline inspection system, new technology for coating, and is claimed to support the biggest sheet size in the digital printing market. With the new Xerox iGen4 EXP press, the printing area has increased by 15%, and the line now supports 364 x 660mm sheets, allowing many more carton blanks to be printed, coated and diecut on one sheet.
The new coating unit, especially designed for digital packaging production, minimizing set-up times by using a sleeve which is easily replaced for new jobs; and an automated cleaning system increases the coater's total efficiency. Water-based coating is applied for the production of pharmaceutical packs, but UV coating is also an option. The buffering stacker is integrated in the coating unit and forms a sheet pile to be passed to the Gallop DC 66 diecutter. The coater is also available as standalone version.
An image inspection system has been integrated for in-line checking of the printed characters of each sheet. Inspection takes place immediately after printing and covers every sheet - even the smallest text flaws or dirt are reliably detected, it is claimed.
Job integrity is “guaranteed” by using a 2D scanner at the diecutter: if there is a discrepancy, operations are stopped.
