Ghosting

Ghosting: A faint unwanted image that appears on a printed sheet of paper where it was not intended. More often than not this problem is a function of graphical design and is very complicated to anticipate. Sometimes you can see the problem developing immediately after printing the sheet (called mechanical ghosting), other times the problem occurs while drying (called chemical ghosting). However the problem occurs, Ghosting is costly to fix, if at all possible. Occasionally it can be fixed by changing the color sequence, the inks, the paper, changing to a press with a drier, printing the problem area in a separate pass through the press or changing the number of sheets placed on the drying rack. Since it is a mostly a function of graphical design, the buyer pays for the increased cost.
