Passport-making processes by country: Security and art in Differences

Passport, as an important document for international travel, is not only a symbol of personal identity, but also a display of national image. Passports of different countries have their own differences in the production process, and these differences are not only reflected in the design style, but also in the production process and material selection of passports. This article will use the passports of several countries as examples to explore the unique aspects of the production process between them.

Chinese passport: Electronic chips and unique views under UV light

China began issuing e-passports in 2012, which have an electronic chip embedded in the traditional ordinary passport and store the holder's basic personal information, facial portrait and fingerprint information. The first page of the passport is printed with the words "People's Republic of China", and the background is a picture of the Great Wall, simple and solemn. Under the ultraviolet light, the inside pages of the passport will show more scenic spots of the country, such as the Great Wall, the Forbidden City, Mount Tai, Li River and other natural landscapes, these patterns appear particularly beautiful and unique under the ultraviolet light, which not only increases the enjoyment of the passport, but also improves the anti-counterfeiting.

Canadian passport: thermal ink with Kinegram image

The process of making Canadian passports is very advanced, and one of the innovative technologies is the use of heat-sensitive ink. On the personal information page, there is a heat-sensitive red maple leaf logo, which will temporarily disappear when the body heat of the finger is applied, and then return, which is an effective means of anti-counterfeiting. In addition, Canadian passports feature Kinegram image technology, which changes colour and moves when viewed from different angles, further enhancing passport security. The inside pages of passports also show richer patterns under ultraviolet light than under ordinary light, which represent changes throughout the year and are both beautiful and practical.

Norwegian passport: Nordic minimalism and aurora effects

The design concept of the Norwegian passport reflects Nordic minimalism, and the cover design is simple and modern. With Norway's famous fjords as the background on the inside of the passport, these patterns will show a stunning "aurora" effect under ultraviolet light, as if Norway's natural beauty is condensed into a small passport. This design not only showcases Norway's natural beauty, but also reflects the country's respect for environmental protection and nature.

Australian passport: Laser engraving with holographic images

The Australian passport is equally exquisite, with a blue cover, printed with the national emblem, the name of the country, the words "passport" and the electronic chip logo. Inside the passport, laser engraving technology is used, which makes the pattern and text more detailed and difficult to forge. In addition, the interior pages of the passport also use holographic image technology, these images will show brilliant colors and dynamic effects under ultraviolet light, such as kangaroos moving from one side of the page to the other side, both to increase the interest of the passport, but also improve the anti-counterfeiting ability.

The differences in passport production processes between countries are not only reflected in the design style, but also in the production process and material selection. These differences make each passport a unique work of art that is both practical and carries rich cultural connotations and security concepts. By understanding the differences in passport making processes, we can better understand the scientific and technological level and cultural traditions of different countries, and enhance international exchanges and cooperation. At the same time, these differences also remind us that when enjoying the convenience brought by the passport, we should always pay attention to its security and anti-counterfeiting, and ensure the security of personally identifiable information.
