Seals in the Sinosphere

A Chinese seal (Chinese: 印章; pinyin: yìnzhāng, Japanese: "hanko" (判子) or "inkan" (印鑑); Korean: "dojang" (도장, 圖章)) is a seal or stamp containing Chinese characters used in East Asia to prove identity on documents, contracts, art, or similar items where authorship is considered important.
Chinese seals are typically made of stone, sometimes of wood, and are typically used with red ink or cinnabar paste (Chinese: 朱砂; pinyin: zhūshā). The word 印 ("yìn") specifically refers to the imprint created by the seal. The colloquial name chop, when referring this kind of seals, was adapted from a Malay word during the colonization of the Straits Settlements.
East Asia currently uses a mixture of seals and hand signatures, and increasingly, electronic signatures. [1] But notably in Japan and China, seals remain commonly used instead of a signatures when doing business or other procedures, and in certain cases, only seals are acceptable.
Types of Seals

- Zhuwen (S:朱文, lit. "red characters") seals imprint the characters in red ink, sometimes referred to as yang seals.
- Baiwen (S:白文, lit. "white characters") seals imprint the background in red, leaving white characters, sometimes referred to as yin seals.
- Zhubaiwen Xiangjianyin (S:朱白文相間印, lit. "red-white characters combined seal") seals use zhuwen and baiwen together.
Seals used by government authorities
Emperors of China, their families and officials used large seals known as xǐ (璽), which corresponds to the Great Seals of Western countries. Xǐ were usually made of jade (although hard wood or precious metal could also be used), and were originally square in shape. They were changed to a rectangular form during the Song Dynasty, but reverted to square during the Qing Dynasty, and officially renamed bǎo (寶, "treasure"). The Forbidden City in Beijing currently has a collection of 25 bǎo from the Qing Dynasty.

These seals typically bore the titles of the offices, rather than the names of the owners. Different seals could be used for different purposes: for example, Emperor Qianlong had a number of appreciation seals [乾隆御覽之寶] used on select paintings in their collection.
The most important of these seals is the Heirloom Seal, which was created by the first Emperor of China, Qin Shihuang, and was seen as a legitimising device embodying or symbolising the Mandate of Heaven. The Heirloom Seal was passed down through several dynasties, but was lost by the beginning of the Ming Dynasty.
The most popular style of script for government seals in the imperial ages (from Song to Qing) is the jiudie wen ("nine-fold script"), a highly stylised font which is unreadable to the untrained.
The government of the Republic of China (Taiwan) has continued to use traditional square seals of about 13 centimetres square, known by a variety of names depending on the user's hierarchy. Part of the inaugural ceremony for the President of the Republic of China includes bestowing on him the Seal of the Republic of China and the Seal of Honor.
The seals of the government of the People's Republic of China today are usually circular in shape, and has a five-pointed star in the centre of the circle. The name of the governmental organization is often arranged around the star in a semi-circle.

Seal paste
There are two types of seal paste depending on what base material they are made of. One is silk based (mixed with cinnabar et al.) to form a very thick substance. The other is plant based to form a very loose substance.
- Silk: The red paste is made from finely pulverized cinnabar, mixed with castor oil, and silk strands. The silk strands bind the mixture together to form a very thick substance. It has a very oily appearance and tends to be a bright red in colour.
- Plant: The red paste is made from finely pulverized cinnabar, mixed with caster oil, and moxa punk. Because the base is a plant one that has been pulverised, the texture is very loose due to the fact that it doesn't bind. The appearance is sponge like and not oily and tends to be a darker shade of red.
Plant based paste tends to dry more quickly than silk based pastes because the plant extract does not hold onto the oil as tightly as silk. Depending on the paper used, plant pastes can dry in 10 to 15 minutes. The more absorbant the paper is, the faster it dries as the paper absorbs most of the oil. Also, plant pastes tend to smudge more easily than silk pastes due to the loose binding agent.
The paste is kept covered after it has been used, in its original container (be it plastic or ceramic). It is kept in an environment away from direct sunlight and away from intense heat lest it dry out.
Chinese usage
Today seals are mainly used on Chinese calligraphy works and Chinese paintings, usually in the order (up-down) of name seal, leisure seal(s), then studio seal.
Usage of seals can extend to banks in China in conjunction with a hand signature. Seals are often good to use as identification with signatures because they are difficult to forge and only the owner has access to his own seal.
Very few people in China now have a complete set of seals; most who do are artists, students, collectors and intellectuals. A well-made seal made from semi-precious stones can cost from ¥400 - ¥4000.
Seals are usually carved out by specialist seal carvers, or by the artists themselves. Seals carved in Chinatown or in major attractions in China are usually done for tourists, rather than the artist. They are often on-the-spot or poor translations of English names on inexpensive soapstone, often featuring Roman characters. Such seals are simply trinkets and are unsuitable for any functional purpose. Authentic, high quality seals are considerably more expensive and require forethought in design and content. Almost all authentic Chinese seals are carved in seal script, but there are exceptions. However, as a rule, regular script, running script, crusive script, etc. is best avoided. The reason for this is that such seal scripts are used for the majority of paintings and books, one function being to contrast the angular lines of the seal characters with the main written body of text.
On the other hand, some people take to carving their own seals out of soapstone and fine knives, which are widely available and is cheaper than paying a professional for expertise, craft, and material. Results vary, but it is possible for individuals to carve perfectly legitimate seals for themselves.
When printing with silk based paste, the user presses his seal into it, applying pressure. However, if the paste is plant based, the seal is lightly tapped into the paste, as with a rubber stamp. The printing surface must be covered fully but not so thickly that it would take too long for it to dry when applied. Usually, the seal and paste are tested before actual use to ensure this. Generally speaking, there should be some soft, pad-like material underneath the material to be stamped.
Determining which side of the seal should face up may be done in a number of ways: if there is a carving on top, the front should face the user; if there is an inscription on the side, it should face to the left of the user; if there is a dot on the side, it should face away from the user.
When the seal is pressed onto the printing surface, the procedure differs according to plant or silk based paste. For silk based paste, the user applies pressure and rocks it about slightly. For plant based paste, the user simply applies light pressure. As lifting the seal vertically away from its imprint may rip or damage paper, the seal is usually lifted off one side at a time, as if bent off from the page. After this, the image may be blotted with a piece of paper to make it dry faster, although this may smudge it.
Once seals are used, as much paste as possible is wiped from the printing surface and the edges off with a suitable material. The seals are kept in a constant environment, especially seals made of sandalwood or black ox horn. Tall thin seals are best kept on their sides, in case it should wobble and fall down. More important seals, such as authority and society seals are encased or wrapped in a silk cloth to add more protection.
Japanese usage
In Japan, there are two kinds of seals: mitome-in ("personal seal") and jitsu-in ("registered seal"). A registered seal is needed to open an account in some banks or to purchase land or a car.
In modern Japan most people have several seals. Men's seals are generally larger than those of women, and high-ranked executives generally have larger hanko, or seal, than their subordinates. The most secure forms of hanko are used for banking and real estate dealings, while off-the-shelf varieties are used for everyday tasks such as signing for delivery of packages.
Registration and certification of an inkan may be obtained in a local municipal office (e.g. city hall). There, a person receives a "certificate of seal impression" (印鑑登録証明書 inkan tōruku shōmei-sho), or certificate of authenticity, which is required for any significant business transaction, such as purchasing a car.
Foreigners who have a valid alien registration card are eligible for the name seal, necessary to perform business. Foreign names may be carved in rōmaji, katakana, hiragana or kanji. Inkan for standard Japanese names may be purchased prefabricated.
Traditionally, inkan are engraved on the end of a stick of hard wood, bone, or ivory, with a diameter between 25 and 75 mm. Carving them is a kind of calligraphic art. Rubber stamps are unacceptable for business purposes.
The first evidence of writing in Japan is a hanko dating from AD 57, made of solid gold and belonging to the Emperor. At first, only the Emperor and his most trusted vassals held hanko, as they were a symbol of the Emperor's authority. Noblemen began using their own personal hanko after 750, and samurai began using them sometime in the Middle Ages. Samurai were permitted exclusive use of red ink. After modernization began in 1870, hanko finally came into general use throughout Japanese society.
The increasing ease with which modern technology allows hanko fraud is beginning to cause some concern that the system will not be able to survive for much longer.
Signature stamps are still used widely in cultures outside of Japan. For instance, some Israeli companies still require stamps on official documents. Some say the relative size of the stamps reflects the rank of the officers within the corporation.
Korean usage
The first Korean royal seal, called oksae (옥새, 玉璽), is thought to be the Seal of the King of Ye (예왕지인, 濊王之印), from Buyeo. During the Goryeo and Joseon periods, there were two types of royal seals in use: guk-in (국인, 國印), sent by Chinese emperors and used in foreign communications, especially with China; and eo-bo (어보, 御寶), used within Korea and in communications with Japan. [2]
With the 1897 declaration of the Korean Empire, new seals were made. In 1948, the newly established South Korea created seals renamed guksae (국새, 國璽). Since 1962, the imprint reads 대한민국 ("Republic of Korea" in Hangul), and the seal was replaced in 1970 and 1999. [3]
Personal seals are called dojang (도장, 圖章) or injang (인장, 印章), although they are rarely used today.
