Abstract
A method for printing quasi-random number tables on cylindrical objects. A quasi random number printing unit is inserted in a blanket cylinder of an object decorator press. A printing plate cylinder disposed within the printing unit is advanced by a cam drive, thereby advancing a plurality of belts entrained about the cylinder and exposing a series of printing plates to an inking unit. Ink is applied from the inking unit to a series of numerical segements on the plates, and from the segments to a cylindrical object surface.
Claims6
A method of printing random numbers on cylindrical objects in a decorating press having a blanket cylinder with a plurality of blanket segments comprising the steps of:
- (a) disposing a printing unit comprising at least two unequal length belts having flexographic printing plates thereon entrained about a printing plate cylinder between two of said blanket segments;
- (b) applying ink to said printing plates;
- (c) rotating a cylinder against said blanket segments and said printing plate cylinder such that a pattern of said flexographic plates disposed over said printing plate cylinder is transferred to said cylinder;
- (d) advancing said unequal length belts through one increment;
- (e) repeating steps (c) and (d).
A method of providing a recyclable can comprising the steps of:
- printing a game number onto said can as part of a universal product code (UPC) symbol;
- said game numbers printed onto said can in a decorating press having a blanket cylinder with a plurality of blanket segments by the steps of:
- (a) disposing a printing unit comprising at least two unequal length belts having flexographic printing plates thereon entrained about a printing plate cylinder between two of said blanket segments;
- (b) applying ink to said printing plates;
- (c) rotating a cylinder against said first and second blanket segments and said printing plate cylinder such that a pattern of said flexographic plates disposed over said printing plate cylinder is transferred to said cylinder;
- (d) advancing said unequal length belts through one increment;
- (e) repeating steps (c) and (d)
- scanning said game number with an optical scanner when said can is submitted to a reverse vending machine;
- printing said game number onto a receipt when said can is submitted to a reverse vending machine and providing said receipt to a user of said machine;
- determining a winning number and providing a prize to said user when said winning number matches said game number.
