Using this technique you can simulate the creasing using multiple parallel press od the blade at reduced
force.
The blade creasing is carried on the back of the print, the means the that the camera does not read the crop
marks but it detects the border and the corner of the sheet.
For this reason you have to measure with a rule the distances of the first marker from the border and the
bottom of the sheet.
You have to measure only once the distance, this technique works well with the last generation of digital
printers, very accurate for the print position on the sheet.
The accuracy depends on the repeatability of the position of the print on the sheets, you can reach a value
around 1 mm then the graphics have to be designed accordingly.
