Dot gain on a pharma label

Name it wrong and you adjust the wrong place

The dots are larger all around than on the signed sample. If you call it something else, you skip this step: use tone value on the control strip. Do not judge by how dark the screen looks. Legal type and the barcode decide release. They do not decide what it is called.

How to tell them apart

What you see Closer to How to separate
Dots larger all around than the signed sample. Dot gain Do not name it from one white spot
Slur stretches in one direction. Gain is all around. Handle it as that other defect Do not use the same adjustment
It sits on the legal type and the barcode Protect this area first Do not ignore the location just to name it

Confirm on the spot

  1. Look, or use a loupe: dots larger all around than the signed sample.
  2. Rule it out: slur is one direction, gain is all around.
  3. Use tone value on the control strip. Do not judge by how dark the screen looks.
