Gravure cylinders are often produced by means of electromechanical burin engraving. Here, the cell shape is known through the shape of the stylus. Here, the 2D measuring method is ideal, offering high working speed and process reliability. The DotScope mini 2D is optimised for this application. It offers the additional option of depth measurement and, by dispensing with ring illumination, a clear view of the measuring field.
In the case of etched or lasered gravure cylinders, the depth profile of the cells is not known. Even with engraved special screens such as Xtreme or the analysis of chrome plating, a pure 2D analysis is not sufficient. This is where the DotScope mini 3D comes in handy, as it enables true 3D analyses.
In addition, it is often necessary to measure certain details on the cylinder. To find these easily and quickly, an xy adjustment and an objective nosepiece are very helpful. For example, one can search for a certain detail with the 5x objective, then – without losing the measuring position – switch to the 10x objective and carry out the analysis.
