Based on the results, the employment is optimized. This procedure leads to good starting results. However, at the beginning of the printing process, images of inferior quality are often printed until the job is optimized.

  • This possibility is very advantageous, since the completeness of the image transfer is of course exactly the size that one intends to optimize by setting the relative position.
  • second values are also measured at a second size, which is not necessarily different.
  • the second measured values can also be pressure values that manifest themselves, for example, in two exposed areas of the nip.
