The present invention relates to a printing roller engraving apparatus having an adjustable mesh mask corrector comprising: a laser generator: a laser focusing apparatus: a first corrector located between the laser focusing apparatus and the printing roller or located in the laser focusing apparatus Between the laser light sources, there is a first disk with a plurality of preset through holes: a second corrector located between the focusing device and the first corrector or between the laser light source and the first corrector, comprising a plurality of A second disk is set in advance through the hole; a first control device controls the rotation of the first corrector and the second corrector: a second control device controls the frequency in the laser pulse: when the first corrector and the second correction When the device is rotated to a certain position, the laser can pass through the first disk and the second disk at the same time, and a pattern is formed on the printing roller. In the present invention, only one laser generator can be used to make a uniform dislocation arrangement. Size and shade of mesh shape, reduce the printing roller scrap rate, and reduce operating costs.
