1. Imperforate (Perforations, roulettes or die cutting)
This means there is no evidence whatsoever of holes (or slits, in the case of roulettes, or die cuts, in the case of modern self-adhesive stamps).There are three variants:
- Totally imperforate.
- Imperforate in one direction - horizontally or vertically. But remember that a coil that is imperforate in one direction is fully imperforate.
- Imperforate between two or more stamps, or between a stamp and its margin.
Type 1: Three types of imperforates: Upper left: Imperforate sheet stamps (Scott 1622b); Upper right: Horizontally imperforate (Scott 538c); Bottom: Imperforate between otherwise normally perforated coils (Scott 2281d).
