Abstract

PURPOSE:To adjust automatically the degree of engraving of an engraving machine for printing by an apparatus wherein the result on measurement of the dimension of an image treating apparatus is compared with the set value and when it exceeds the allowable range, a means for adjusting the degree of engraving of an engraving machine for printing is provided. CONSTITUTION:By using an automatically adjusting apparatus of an engraving machine for printing, the surface image of a highly rotating copper sheet-made cylinder 10 is taken in by means of a camera 4 by synchronizing with the emission of a strobo-unit 6 and the dimension of an engraving is measured by treating the image by means of an image treating apparatus 3 and it is compared with the set dimensional data and when it exceeds the allowable range, the difference in dimension is converted into the vol. amount and the size of the engraving can be adjusted by outputting to a vol. control apparatus 8. Therefore, as the degree of engraving which has been conventionally done by human visual evaluation can be grasped uniformly by means of image treatment, no individual difference takes place and automation of the engraving by means of the engraving machine for printing can be performed.
