$a Method of computer template adjustment for wood laser engraving $f Maria Zykova ... [et al.] 215 $c Graf., obr., tab. 320 $a Lit. 330 $a To achieve the identity of wood-engraved replicas with a pseudo-volume original, it is necessary to adjust the computer model. The method of selecting the model tone range ensuring the reproduction of the original light-and-dark transitions in the replica is introduced in the paper. The method is based on the selection of boundary values of the model black color saturation, taking into account the brightness threshold value perceptible to a human eye. Two methods for determining the boundary values of the model tone saturation were compared – visual by expert assessments and instrumental by scanning replicas and processing scans in Photoshop. The model black color saturation recommended for beech wood in CMYK color space was 2% (lower boundary value) up to 33% (upper boundary value). 463 -1
