This stamp was dry printed, meaning the paper was not moistened as much as with wet printing. Dry printing gives the stamps a slightly more crisp appearance, and it eliminated the problem of paper shrinkage.
Dry Printing - the printing of intaglio stamps on paper with low moisture content. Dry printing was first used at the BEP in 1953. All Bureau Issues have been dry printed since the late 1950s. Compare: Wet Printing.
Wet printing: has a moisture content of 15-35% compared to 5-10% for "dry" printing; also has a duller look than "dry" printing.
