A cold roll laser texturing method relates to a method for carrying out laser texturing on a cold roll and aims to solve problems of short service life, short roll replacement period, high cost, and the like, which exist in present laser texturing technologies. The method comprises the following steps: firstly parameters are determined, wherein, input power of a laser ranges from 2KW to 7KW, optical pulse power ranges from 32W to 45W, spot size ranges from 60 microns to 100 microns, dot pitch ranges from 100 microns to 150 microns, thread pitch ranges from 80 microns to 100 microns, optical pulse width ranges from 2mus to 10mus, the rate of randomness ranges from 60 percent to 80 percent, the density of distribution ranges from 50 dots/mm<2> to 70 dots/mm<2>, and texturing roughness ranges from 0.7 micron to 1.5 microns; and secondly, the laser texturing for the surface of the cold roll is carried out according to the parameters determined in the first step.
