How to tell the authenticity of stamps?

1, the real ticket has clear pattern, three-dimensional pattern, soft and uniform color, and the fake ticket has thick dot, distorted font, blurred pattern, overlapping colors and exposed colors, which can be seen more clearly through a 20-fold magnifying glass.

Real stamps are made of stamp paper specially designed by the manufacturer designated by the postal department. These "painted stamp papers" are obviously different from ordinary offset paper and coated paper in color. From the surface of the paper, you can see the authenticity.

3. Real stamps are positive in tone and rich in color, while fake stamps are offset printed with ordinary ink, so the color is inevitably dim. Moreover, color overlap and red exposure are not allowed because of the color matching, and there will be a brush color that is very different from the real ticket under the light. When viewed through a magnifying glass of 20 times, patterns often show outstanding points.

4. The specifications of ticket width are calculated in millimeters. Knowing the exact width of each set of stamps, you will know how wide the edges around each set of stamps should be. It is more accurate to identify the authenticity of a ticket with a magnifying glass and a ruler. Experienced stamp collectors can even see through the fake toothless tickets with their teeth cut off by visual inspection.

5. The real stamp tooth profile is full of articles. Stamp printing equipment has strict technical standards and is regularly maintained and updated. The punched holes are regular, smooth and flat. But counterfeiters can't have the same technical conditions and can only make do with it. Visually, it can be seen that some fake tickets are similar to triangular perforations, which are groove-shaped and polygonal perforations under a magnifying glass.

6. The glue on the back of stamps is also one of the elements to study and distinguish the authenticity of stamps. At present, fake tickets are generally found without adhesive, and some are painted with a layer of translucent white paint on the back of the ticket to pretend to be adhesive, but it is useless. Some are painted with glue, because the technology is so poor that even the perforated paper wool is stained with glue.

Extended data:

Maintain common sense:

First, you must use a dry pouch, or a dry glass bottle, or a dry stamp album when collecting stamps. Generally speaking, stamp albums and pouches are commonly used.

Second, we must pay attention to the environment in which stamps are stored. No matter whether you use a stamp album or a protective bag to collect stamps, you should not expose them to the sun for a long time, otherwise the stamps may become discolored and cannot be stored in a humid environment, because the stamps are paper, absorbent and prone to mildew. So it is best to store stamps in a cool and dry place, and you can put some desiccant together.

Third, if you choose a stamp album to collect stamps, you should also pay attention to the arrangement method of the stamp album. Never put it sideways. Over time, the stamps in the album will be squeezed by the weight of the book. Therefore, the arrangement of stamp albums should be like books in the library, standing side by side, not staggered, and books should not be too close together, leaving some gaps.

Fourth, when watching or moving stamps, you must not touch them directly, but use special tweezers to clamp them, because there are often oily secretions on your fingers, which may leave fingerprints on stamps. Over time, traces will appear, damaging the appearance of stamps.
