Which register matters on a label with a clear window

On a label with a clear window, the register that matters is the artwork against the window, not only the crosshair between colours. The crosshair can be right and the window can still cut into the text. The window edge should be its own register object.

Why it is judged this way

The window comes from die-cutting or from an unprinted area. Print register and die-cut register are two things. What the customer complains about is usually text falling into the clear area, while the colour marks may still pass. The template has to put the window outline and the nearest text in the same field of view.

What to compare

What you see Call it Do not
Text enters the window Register fail Release it because the colour marks passed
Colour is off colour Judge it as colour-to-colour register Mix it into the window item
The window edge cannot be seen Change the light or the field first Adjust the press

Check at a job change or a new roll

  1. The field of view must hold the window edge and the nearest text together.
  2. Offset the cut on purpose and confirm it alarms.
  3. Write the colour-mark conclusion and the window conclusion apart.
