FIELD: physics, optics.
SUBSTANCE: method of measuring laser processing alignment applicable to a reel-to-reel manufacturing process, including a laser processing stage, wherein before at least one laser processing stage, marks, patterns or surfaces are made with printing ink on the base or carrier material of a web, and on which the laser beam used can make a mark by removing or changing the printing ink. At the laser processing stage, another mark is made with the laser beam on the mark printed with printing ink, and the position of the mark printed with printing ink and the mark made with the laser are read optically to measure the alignment of the printing ink stage and the laser processing stage.
EFFECT: high efficiency of the method.
