Void on a food web

Name it wrong and you adjust the wrong place

It is a clean-edged white spot, with paper or film in the middle. If you treat it as another defect, you skip this step: check ink laydown and pressure of this colour first, and do not add ink first. On a food web the ingredient list and the heat-seal area decide whether it ships. They do not decide what it is called.

How to tell them apart

What you see Closer to How you separate them
A clean-edged white spot, with paper or film in the middle. A void Naming it from one white spot
A hickey has an ink ring or a black center. A void does not. Handle it as that other defect Using the same adjustment
The spot sits on the ingredient list or the heat-seal area Hold this area first Ignoring the position just to name it

Confirm it on the spot

  1. Look by eye or with a loupe: a clean-edged white spot, paper or film in the middle.
  2. Rule it out: a hickey has an ink ring or a black center, and a void does not.
  3. Check ink laydown and pressure of this colour first. Do not add ink first.
