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