The introduction and development of mechanized printing

Modern printing technology mainly includes direct printing with lead movable type typesetting, and the use of lead movable type as the master plate, the replica plate casted by clay or paper, and the photographic copper-zinc plate produced after the use of photography for printing plate-making for printing. Letterpress, lithography with lithography, collolithography and photolithography, lithography with indirect printing, gravure with printing with engraving gravure and gravure (photolithography).

These modern printing techniques were introduced into China one after another for more than 100 years from the beginning of the nineteenth century, and developed rapidly during the national crisis and the struggle between the Chinese nation and foreign invaders.

Letterpress printing is a process technology of printing with letterpress with the graphic part higher than the blank part. The traditional printing invented and used in China for more than a thousand years - block printing and movable type printing belong to this category.

01 Lead movable type printing

Movable type printing is a technology that uses movable type to form a complete layout for printing, which has existed in ancient China.

The difference is that the lead movable type of the modern lead movable type printing technique introduced from the West is made of lead, antimony and tin three metals fused in proportion. for advanced typography. The time of its introduction generally begins in 1807, when Morrison hired people to carve Chinese characters in Guangzhou.

02Clay plate, paper type lithography

The printing plate made of clay plate and paper type casting cliché, usually called "copy plate".

The production process of the replica plate is to first arrange the movable type plate that is exactly the same as that of the lead movable type plate directly printed according to the requirements, and then use the movable type plate as the master to press the mud or special thick paper into a negative type version called mud type and paper type, and then use mud Type or paper casting cliché, and finally use the cliché (full page) as a printing plate for printing.

The invention and application of this process technology marks a new stage in the development of letterpress printing in modern times.

The time when clay tablets were introduced into China was when the technology of engraving and casting was initially developed after the introduction of movable type printing. In the early days of the establishment, the Huahua Bible Study Room in Macau, the Zilinxi Newspaper Office in Shanghai, the Zhuyi Hall and the Declaration Hall in the United States all used clay blocks to copy the stereotypes for printing.

03Photo copper-zinc plate

The further development of letterpress printing is the invention and application of photographic copper-zinc plates, which appeared when photography was applied to printing plate making. Although there have been inventions and applications of electroplated copper plates, plaster plates and boxwood plates before, they have not been used for a long time because of their shortcomings.

The photographic copper-zinc plate is the product of the application of photography to printing plate making. It mainly includes photographic copper plates and photographic zinc plates, which are commonly referred to as copper-zinc plates. Invented in 1855 by Frenchman M.Cillot, it was introduced to China at the end of the nineteenth century. In the order of its invention and introduction, there are single-color photographic zinc plates and copper plates, and the trial production and application of two-color, three-color, and four-color photographic mesh copper plates. Among them, the former is a monochrome letterpress, and the latter is a color letterpress.

04Toppan plate making and printing machinery

Letterpress printing machinery mainly includes letterpress plate-making machinery and letterpress printing machinery.

Among them, letterpress plate-making machinery is mainly used for type-casting machinery for movable type production and pressing machine for duplicating plates, as well as plate-making photographic equipment that appears after photography is used in letterpress plate-making, while letterpress printing machinery is mainly various letterpress printing machines machine.

Most of these mechanical devices, especially the simpler ones in the early days, came directly from Western countries or were introduced to China through Japan. It is inevitable that it will be introduced at the same time as various letterpress printing techniques.
