A laser process alignment measuring method applicable to a reel-to-reel manufacturing process including a laser process stage, wherein before at least one laser process stage, on the base or carrier material of the web (2) are made marks, patterns or surfaces (4, 9) with printing ink, on which the laser beam used can make a mark (7, 10), for example, by removing or changing the printing ink, whereby at the laser process stage, another mark is plotted with the laser beam on the said mark printed with printing ink, and the position of the mark printed with printing ink (4, 9) and the mark plotted with the laser (7, 10) are read optically to measure the alignment of the printing ink stage and the laser process stage. |
