Die proof (philately)

Sub-sample pressure is defined as the final pressure before beginning the actual intended for trade edition of printmaking, or for stamps, the provisions for the Postal Service stamps.

The sample pressure serves the re-examination of the printing form. The final determination of the ink is then made. Every now and then it happens that even Proof copies arrive as highly prized rarity on the market that are very sought after by collectors.

In the manual printmaking such proofs epreuves d' état ​​(French for state prints) are referred to; the " Contre- Épreuve " (French for back pressure) occurs when the still wet paper sheet of the sample pressure is placed a second sheet and reproduces them again with the help of the printing press, Contre- Épreuve then corresponds to the image on the original printing plate is therefore not inverted, as the original graph. Such deductions facilitate the engraver or the artist the correction work on the printing plate and are usually not intended for actually art trade.

However, a sample pressure is not to be confused with a printed, essay, a pressure test or a machine sample.
