In some cases, a type of paper is very important. Stamp No. 9 (50/7 kn Slavonija) from the 1945 DFJ Mostar issue is a good example. This stamp exists on intaglio paper and has a price of a few tens of euros. However, there are also 50 pieces on offset paper valued at 700 euros or even more. Therefore, it is very important that we know how to determine the type of the paper. One of the methods is paper thickness measurement.
I got a new, super-accurate paper thickness gauge a few days ago. Its accuracy is one-thousandth of a millimetre.
My new paper thickness gauge.
I checked some of my old measurements and here are the results for the Croatian Landscapes issue:
- Offset paper: 0.085 - 0.095 mm
- Intaglio paper: 0.071 - 0.080 mm
- Porous paper: 0.078 - 0.091 mm
- Pelure paper: 0.050 - 0.057 mm
