10 Postage Printing Methods For Stamps (Master List)
Even though stamp printing dates back to the 19th century, but it is still a relatively recent invention compared to how long the postal service has existed.
Over the past century, the printing process has undergone several changes as different countries have employed various processes.Each printing technique was created to prevent unlicensed duplication or the sale of fake goods.
Printing was done:
- Printing plate prep
- Chemical additions
- Different printing presses
It’s all explained in this video :
What is the final step in pre-printing?
Making the printing plate is the last stage in the pre-printing process. The die has been replaced on the transfer press’s bed with a flat piece of soft steel. Over this, mild steel is one of the reliefs on the transfer roll.
Dots that govern the location or arrangement on the plate are in the right place. On the scale, the dots have been softly marked in advance. Following the same procedure used to make the transfer roll, the design is rocked in once the proper relief position has been established.
The distinction is that the image is being transferred to the transfer roll this time, rather than from it. The design is reversed and recessed once it has been applied to the plate. The number of transfers entered on the scale equals the number of subjects printed on the postage stamp sheet.
Double, shifted, and re-entries transfers take place throughout this operation. These happen due to photos that were not adequately burnished out before being rocked in and inserted incorrectly.
The many printing techniques include :
- Intaglio (“Line engraving”)
- Photogravure
- Typographic (“Letterpress”)
- Lithography
- Offset Lithography
- Photolithography
- Embossing
- Holographic
- Embroidered
- Thermochromic
| 👉 Intaglio (“Line engraving”) : Line engraving is a technique used in intaglio. Intaglio printing was used to create the very first stamp, the Penny Black. Intaglio is Italian for “engraved.” This method produces crisply detailed stamps. Due to the difficulty in duplicating, this technique creates a crucial security measure for both stamps and banknotes.
👉 Photogravure : The stamp image is transferred to chemically treated metal (or, in modern times, plastic) via the Photogravure technique. Each colour was given its own plate. This technique produces a smooth surface and uses small dots (also considered recess printing). 👉 Typographic (“Letterpress”) : Typographic printing, often known as “Letterpress,” uses a raised pattern on the printing plate as opposed to one that is recessed. Looking at the stamp’s reverse, one can see the printed portions recessed into the paper. 👉 Offset Lithography : The image is transferred from the printing plate to the rubber and then to the paper using offset lithography. Most multicoloured stamps produced globally are produced using a quick variation of this procedure. 👉 Photolithography : The contemporary litho-method, known as photolithography, transfers a photo image’s negative to a plate using a chemical mixture. 👉 Embossing : The stamp can have a three-dimensional appearance by embossing. The picture is elevated above the stamp’s surface. 👉 Holographic: Since 1988, holographic stamps have been in use. This technique uses a metal foil that, when illuminated, seems three-dimensional. 👉 Holographic: Since 1988, holographic stamps have been in use. This technique uses a metal foil that, when illuminated, seems three-dimensional. 👉 Embroidered : Switzerland is where embroidered stamps were first made. 👉 Thermochromic : A “Thermochromic” stamp, which changes colour in response to temperature, was introduced by Great Britain. |
Printing Methods For Stamps-FAQ
What are the different methods of stamp printing?
This more recent printing technique is more affordable and dependable. Different printing techniques and methods are utilised for creating stamps.
The most common ones include offset lithography printing, photogravure, letterpress, engraving, and intaglio. The printing method used by each stamp printing machine makes a difference.
How are stamps made?
The stamp design is transferred to the paper or other materials from which stamps are manufactured as the plate revolves around the cylinder. Each stamp colour has its own printing unit.
The primary hues are cyan, magenta, yellow, and black. The processes for printing stamps have generally evolved over time.
What is the history of stamp printing?
Before 1970, most stamps were recess-printed from steel or copper plates. The technique used for this is intaglio. Intaglio stamps can be identified by the faint ridges that form when the paper is pressed firmly into the plate’s grooves.
What is photogravure stamp printing?
The first examples of photogravure stamp printing can be found in the 1830s. Actually, it is an intaglio printmaking technique in which mechanical etching plates are used to print photographs.
This technique uses a photography procedure to adhere to the stamp’s design on the cylinder.
What is a letterpress stamp?
Surface-printed or typographed stamps are other names for letterpress stamps. Between 1855 and Queen Victoria’s death in 1857.
What is offset printing?
Surface-printed or typographed stamps are other names for letterpress stamps. Between 1855 and Queen Victoria’s death in 1857.
What is the difference between lithographed and photogravure stamps?
Lithographed stamps typically don’t have the same sense of depth as most relief stamps. Compared to photogravure stamps, they also frequently have sharper and cleaner edges.
How are embossed stamps printed?
The stamp paper is pressed between a recess and a relief die to create embossed stamps, which are much less common than the three methods mentioned above. As a result, the logo has a three-dimensional shape that projects inwardly from one side and outwardly from the other.
Why is it important to know about stamp printing?
But when one gets more involved in stamp collecting, understanding the methods used to create stamps becomes more crucial.
The market values of symbols are frequently significantly impacted by the fact that different stamps from various countries have the same design but were manufactured using various printing techniques.
What are the different types of printing methods?
Printing techniques can be divided into four categories: intaglio, relief, planographic, and embossing.
Which method of printing is used for postage stamps?
A depression etched or carved into the surface of a printing plate holds the ink in the engraving stamp printing technique.
The primary features of the gravure stamp printing technique are the printing plates’ surface cells or recesses. It is completely covered with ink as it passes through.
How many types of postage stamp are there?
By 2000, there were 400,000 different varieties of stamps in circulation thanks to the production of scores of other logos each year by hundreds of different countries. The average annual global output is 10,000 different varieties.
