Ghosting on an offset sheet

Mechanical ghosting is a faint second image on the same side of the sheet. The ink film on the rollers was starved or overcharged by the image ahead of it.

Checks

1. Confirm it is on the printed side and matches a shape on that form. A mark on the back is set-off.
2. Heavy solids next to open areas are the classic layout. Changing the layout or the ink take-off is the fix, not more pressure.
3. Check roller settings and ink film. A roller that is not eating ink evenly ghosts.
4. A different ink body can reduce it. Test a drawdown only after you know it is ghosting and not a blanket smash.
