Number printing method of securities, how to handle the number printed securities, and number printing apparatus for carrying out a number printing method

摘要

Relates to a method for numbering the plurality of substrates having a plurality of security prints which are arranged in n rows and k columns the product k * n is an integer multiple of 25 or 10. By applying a serial number for each of the security prints, the method comprises the step of numbering the substrate a continuous process units consisting of 10 ^N pieces. The serial number is calculated by the following formula. Serial number (Serial #) = Start # + α * [(r-1) * k * n * 10 ^N + ((i-1) * n + (j-1)) * 10 N + MOD (s-1; 10 ^N)] where, Start # is a starting number for starting the numbering, the α, +1 or -1 depending on whether is carried towards one of the increasing direction numbering or decreasing direction Yes, identifies the unit of processing substrates continuous 10 ^N images, identifies the rows and columns on a substrate of security prints each, to be numbering is placed, r is, s i and j is a number that identifies the base material security prints to be numbering is placed, function MOD and (x; y) is a Iru method function where to return the remainder of the integer division of y at x. Digit N + 1 and N + 2 digit serial number (Serial #) is activated continuous (13, 14) double numbering wheel bearing a predetermined digit pairs digit sequence for N + 1 and N + 2 digits It is produced by. Numbering box for carrying out the numbering methods are described as well.
