ROTARY PRESS
Document Type and Number:
Japanese Patent JPS5825962
Kind Code:
A
Abstract:
A continuous print is produced on a half-width web (3) using one printing unit. After the first pass between the two printing cylinders (22, 23) the web is guided around a return loop in which it is laterally displaced and is then conveyed a second time between the same cylinders (22, 23). On the first pass successive first images (D1) are printed and on the second pass successive second images (D2) are printed; the length of each image (D1 and D2) is equal to half the circumference of the cylinders (22, 23) (or the sum of the image lengths is equal to the full circumference) and the length of the return loop (I1-I2) is fixed at an odd numbered multiple of the image lengths, so that the printed images (D1, D2) follow one another on the web without a gap. The loop length adjustment is made by means of displaceable rollers (24, 25). If continuous printing on one side only is required, the cylinder 23 may be an impression cylinder. The image lengths may be made longer so that partial overprinting occurs. The edges of the images should be non-straight to make the joins between adjacent images less noticeable. The printing cylinders (22, 23) may be offset cylinders applied with an image from plate cylinders.
