laser engraving, wood, half-tone wedge, template correction, tone range


The method of correcting templates of pseudo-3D images engraved on wood and wooden materials is proposed. The key elements of the method comprise initial engraving of the test model with an optic density gradient, measurement followed by further analysis of the engraving optical density, finding the threshold values of the workpiece material tone, and correction of the image output values. The algorithm is composed, and the variant for automating the template design is proposed. A more complete reproduction of light-and-dark gradations of the image engraved is achieved in the material, and the template design is accelerated and simplified. The experiments confirming the efficiency of the proposed approach were carried out.
