What happens when a stamp is gummed on the wrong side?
Stamps with a gum error are gummed on the wrong side or on both sides at once. As a result, the item has a sticky face and a flat back, which automatically renders it invalid. Originally, gum was applied manually between printing and perforating, since the paper had to be damp to get a good impression.
What causes a stamp to have the wrong denomination?
When the stamp comes with a wrong denomination, we have a value error at hand. It can be a high-value denomination on a design meant for lower values or vise versa. Value errors typically occur because of confusingly similar designs or an excessive variety of denominations.
Why are imperforate errors more common on coil stamps?
Because perforations can be removed by trimming, philatelists only collect imperforate errors in pairs, blocks or sheets. Imperforate errors occur more frequently in coil stamps, where printing tends to be automated and there is little opportunity to check for faults.

What to do if your stamping press is bad?
Some companies try to compensate for a poorly maintained press by adding oversized guide pins or grinding the guide pin ends to a cone shape. Care must be taken when flipping die shoes over so that the guide pins are not bent.
