Abstract
There is described an intaglio printing press (*) comprising a plate cylinder () carrying one or more intaglio printing plates, the plate cylinder () receiving ink from an inking system (*) having a plurality of chablon cylinders (*) transferring ink directly or indirectly onto the plate cylinder (), the intaglio printing press (*) comprising an adjustment system acting on the chablon cylinders (*) in order to compensate elongation of the one or more intaglio printing plates. The adjustment system comprises, for each chablon cylinder (*), an adjustable drive unit, which adjustable drive unit () is interposed between the chablon cylinder (*) acting as a rotating output body of the adjustable drive unit () and a driving gear () acting as a rotating input body of the adjustable drive unit (). The adjustable drive unit () is designed to allow selected adjustment of a rotational speed of the chablon cylinder (*) with respect to a rotational speed of the driving gear (). In an adjusting state of the adjustable drive unit (), driving into rotation of the chablon cylinder (*) is adjusted over each revolution of the chablon cylinder (*) by means of an adjustment motor () of the adjustable drive unit (). In a non-adjusting state of the adjustable drive unit (), the adjustment motor () is inoperative and driving into rotation of the chablon cylinder (*) is performed exclusively mechanically via the adjustable drive unit (), the chablon cylinder (*) rotating at a same rotational speed as the driving gear ().
