Do you recognize the attached register mark?
How does one read it? (e.g. the marks in the circles)
The scale in the top is in mm with 0,1 mm steps but the corresponding scale below? What unit is that and how should the deviation be measured?
Do the SID elements in the bottom requires special equipment to read it?
What type of printing is this mark used for?
