Title: Improvements in Offset Printing
IPC: B41L19/00
Filed: 1967-07-27
Abstract: 1,163,280. Offset printing. E. I. DU PONT DE NEMOURS & CO. 27 July, 1967 [28 July, 1966], No. 34655/67. Heading B6C. An offset proofing or printing process comprises mounting a matrix on one segment of a printing cylinder which also carries a receptor sheet on an opposite segment, contacting the printing cylinder with an offset cylinder and transferring an image from the matrix to the offset surface and thence to the receptor sheet, the matrix comprising a layer which has unexposed pressure-softenable image areas and complementary exposed and hardened areas. Preferably the matrix has printing areas comprising a polymerizable monomer and a thixotropic agent, the non-printing areas having been exposed to ultra-violet radiation through a halftone screen in order to form a hard polymer from the monomer. The unexposed areas are shear sensitive and become fluid under pressure, so that image transfer occurs. Multiple revolutions are generally necessary for satisfactory transfer, and different coloured matrices having the same image may be used in succession. Suitable photo-polymerizable materials are disclosed in Specification 1,150,829. Apparatus.-The matrix and the receptor sheet are locked on to the printing cylinder (4) by means of vacuum applied through open-air channels (7) set in the cylinder, and are registered by means of pins (6) embedded in the cylinder (Fig. 1, not shown). The printing cylinder is preferably twice the diameter of the offset cylinder, and the cylinders are then geared together so that the offset cylinder rotates at twice the speed of the printing cylinder. With reference to Fig. 4, the offset cylinder shaft 17 is eccentrically constructed and arranged so that the offset cylinder can be engaged or disengaged by rotation of a pivot arm 14 in which the shaft is mounted. The pivot arm 14 is slidably mounted with respect to the shaft so that cam followers (15), 16 carried on the sides of the arm can ride on either disengage cam (13) or engage cam 12 carried on the printing cylinder shaft. Sliding movement of the pivot arm 14 is controlled by solenoids actuated by a starting signal and by a stopping signal after a pre-set number of cylinder revolutions so that the required cam controls movement of the pivot arm (see also Figs. 2 and 5, not shown). The pivot arm may be magnetically locked in the engage or disengage position.
