METHOD FOR DETERMINING-CALCULATING POSITIONS Russian patent published in 2005 - IPC

FIELD: marking.

SUBSTANCE: method includes picking cyclic numeric row with property, that position in numeric row of each numeric series of predetermined length is determined unambiguously, multiple marks are printed on the surface in accordance to multiple samples of cyclic numeric row, samples of which have different values of cyclic displacement, and printing of marks is performed with preset displacements between adjacent samples. Result is achieved because printing stage includes dividing surface in given direction on multiple code ports, each of which includes at least three samples of cyclic numeric row, one of which in each code port is common for adjacent code ports, and marks are printed in a way, so that position of each code port in given direction was encoded by means of displacements between samples of cyclic numeric row, belonging to code port.

EFFECT: possible encoding of greater number of positions.
