Philatelic Word Of The Day
| Double Joint Line | A joint line on rotary press stamps that appears to be two parallel lines, rather than the usual solid line. This phenomenon occurs when the gap between the two rotary plates is somewhat wider than normal. Note that a joint line is created when the ink spills over into the gap between the two rotary press plates attached to the printing cylinder. Joint lines are not to be confused with guide lines, which were printed intentionally, however similar they may appear. |
