Scumming on a textured wine label

Name it wrong and you adjust the wrong place

A tint of ink where no ink belongs. If you call it something else, you skip this step: check ink-water balance first. Do not increase impression. The wine name and fine type decide release. They do not decide what it is called.

How to tell them apart

What you see Closer to How to separate
A tint of ink where no ink belongs. Scumming Do not name it from one white spot
Fill-in makes the image heavier. Scumming sits in the blank. Handle it as that other defect Do not use the same adjustment
It sits on the wine name and fine type Protect this area first Do not ignore the location just to name it

Confirm on the spot

  1. Look, or use a loupe: a tint of ink where no ink belongs.
  2. Rule it out: fill-in makes the image heavier, scumming sits in the blank.
  3. Check ink-water balance first. Do not increase impression.
