Abstract: A method for identifying a lateral position of a vibrator roll geared to a plate cylinder in a printing press includes the steps of sensing a reference lateral position of a vibrator roll, setting a counter to a setting corresponding to the reference lateral position of the vibrator roll and rotating a plate cylinder.

Abstract: A method for controlling a chill roll system in a web printing press includes calculating, based on a web inlet temperature of a web entering a first chill roll of the chill roll system, a dew point temperature of an ink solvent vapor of ink printed on the web is calculated. The inlet coolant temperature of coolant entering the first chill roll is set to temperature value near the calculated dew point temperature. Using a heat transfer model, the flow rate of the coolant through the first chill roll needed to maintain a temperature rise of the coolant through the first chill roll below a predetermined value is determined. The method prevents post-chill marking by sufficiently cooling the web, and sets chill roll temperature profiles to avoid solvent condensation on chill roll surfaces and thereby avoid condensate marking.

Abstract: A guide roll (22, 24) for a printing press (10) printing an image on a flat surface (16) of a web (12) of a lenticular lens material. The other side of the material has a series of lenticules (14) formed on it which extend parallel of each other longitudinally of the web and generally across the width of the web. The surface on which the lenticules are formed is drawn across the guide roll as the web of material is pulled through the press. The guide roll has a band (B) of circumferentially extending grooves (G) formed on an outer surface (26) of the roller. The grooves are formed so at least one lenticule fits in each groove. Thus, as the web is drawn through the press, and across the idler roller, the grooves prevent both lateral movement of the web with respect to the press, and distortion of the web. This helps maintain a printing alignment established between the printing press and the web of material prior to beginning a print run.

At least one roller of the roller train has a resilient cylindrical outer layer which contacts the peripheral surface of at least one other roller of the train and surrounds an adjustable rotary eccentric which biases the cylindrical outer layer against the at least one other roller with a force determined by a prestressed coil spring. The eccentric is oscillatable axially against the opposition of a second spring, such as a diaphragm spring.
