Abstract: A method for producing color steel plate with multicolored patterns, the PLC control module of servo control system collects the process and rotation speed of each roller of the roller coating unit, calculates out and makes the theoretical roller surface linear velocity be consistent with the process rotation speed; conversely, the actual roller surface linear velocity of each roller of roller coating unit is collected by servo control module having an encoder, and the signal of actual roller surface linear velocity is input into the PLC control system, so that PLC control system can compare actual and theoretical roller surface linear velocity, and adjust current frequency until actual and theoretical roller surface linear velocity are consistent. Control method ensures actual roller surface linear velocity is consistent with process rotation speed, so there is no need to stop the line for adjusting in the production process, thus increasing the production efficiency.

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.

Abstract: A printing press includes a pair of in-line central impression cylinders which rotate about parallel axes. A web which is printed on the central impression cylinders is advanced from one of the cylinders to the other along a path which is perpendicular to the axes. The web is advanced from an unwind to the first central impression cylinder along a path which is parallel to the axes, and the web is advanced from the second central impression cylinder to a rewind along a path which is parallel to the axis. The web path between the central impression cylinders is relatively short, and the printed side of the web does not contact any rolls except possibly a laydown roll before the second impression cylinder. The central impression cylinders and the plate rolls are driven by different servo motors, and a controller controls the servo motors for adjusting the repeat of the printed images.

The pressure applying unit (and the counter pressure applying unit) deformes the paper web in a wavy surface which causes the width of the paper web to be shortened. The adjusting factors for the web width are controlled by automatic control system which detects traveling condition of the paper web, the generation of shears in printing, etc.

Abstract: A printing press damping system (10) has a set of rollers (12,1,15,16) to deliver a damping fluid (14) from a trough (11) to a plate cylinder (20) of a printing press. The rollers comprise a fountain roller (12) which is rotatable within the trough to pick up damping fluid (14) which is then transferred to a feed roller (1) then to a distributor roller (15) and finally a damping roller (16) which delivers the damping fluid (14) onto the plate cylinder (20). The fountain roller (12) and distributor roller (15) each have their own drive means.

Abstract: An accent color printer for printing on a continuous web of material has spaced apart drums, and a flexible continuous belt positioned around the drums. The belt defines a transport path having an arcuate portion at one of the drums. A platen cooperates with the belt to define a curvilinear print region for said transport path. An input module positions a continuous web onto the moving belt. Print heads positioned adjacent the belt print accent colors onto the web at the print region. An outfeed module removes the web from the belt at arcuate portion of the transport path and tensions the removed web whereby the web forms a capstan wrap with the belt at the arcuate portion of the transport path. The capstan wrap results in the tension in the web at the printer region being increased from the tension in the web removed from the belt.

Subsequently, a rotating silk screen applies a pattern of viscous translucent ink to form extraordinarily thick ridges on selected portions of the four-color image and opaque ink layer. Finally, a metalized substrate is laminated to the plastic substrate over the various ink layers.
