Abstract: A method and apparatus for printing a single image at a time in a flexographic printing environment. The present invention utilizes a flexographic plate cylinder which has been modified by forming a groove in its circumference. The groove extends partially around the circumference of the cylinder, leaving an area approximately equal to the area of a single flexographic plate. A belt having a plurality of flexographic plates mounted thereon is entrained about the printing cylinder coincident with the groove and raised area. The groove prevents transfer of the flexographic image to a film passing between the impression cylinder and printing cylinder. Only when the raised area is adjacent the impression cylinder will an image be transferred from a flexographic plate. In addition, only the plate over the raised area is inked when the flexographic belt passes an anilox inking roller. This prevents the accumulation of ink on plates that are not used for image transfer on a particular rotation of the belt.

Abstract: Method and apparatus for printing quasi random number tables comprising a printing press having one or more printing stations incorporating a plurality of endless belts, each entrained around a printing plate cylinder and an idle roller, each belt being a different length which is a multiple of a basic pitch value, and each belt having affixed to the outer surface thereof and arranged in a row along the length of the belt, a plurality of printing plates arranged to print an impression onto a web or other medium passing through the press in register with a similar impression printed by each other belt. In one form of the invention each plate prints a number such that each belt prints different numbers in register, forming larger numbers or tables whose digits change from impression to impression in a quasi random manner. In one form of the invention each printing station incorporates one said belt.

Abstract: Apparatus for printing quasi random number tables used in games of chance comprising a flexographic printing press, such as a Victory Kidder Press, provided with a number of cylinders of different circumferences arrayed about a central drum. Each circumference is a multiple of a basic pitch value and each cylinder is arranged to print columns of numbers or other symbols alongside similar columns printed by the other cylinders in a quasi random array.The tables may be printed on a large number of different materials such as; newspaper preprints, plastic film food wrappers, card, etc.

Abstract: Apparatus for printing quasi number random tables used in games of chance onto newspaper preprints for convenient insertion into and distribution with newspapers. The apparatus comprises a flexographic printing press, such as a Victory Kidder press, provided with a number of cylinders of different circumferences arranged about a central drum. Each circumference is a multiple of a basic pitch value and each cylinder is arranged to print numbers or other symbols to be interspaced between numbers or symbols printed by other cylinders in a quasi random array.
