Door to Screen-Printing

- A Secret Story of Screen-Printing -

The history of printing is very old and said that letterpress originated with Germany is the oldest.
Letterpress is a terribly time-consuming method compared with present electric process or offset printing: first, type, which is made from lead, is picked out and composed piece by piece, and page and page, and a sheet of pasteboard put on a composed page is pressed to make a paper mold. Then lead is poured into the mold to make a printing plate to print with.

Japanese textile printing is considered the parent of stencil printing that screen-printing is classified as.
It was for printing on cloth with stencils cut out of lacquered paper, and said that it was born in Shirako, Mie Prefecture.
However, stencil printing cannot transfer some patterns such as the inner of a double circle, so they used to tie the inner patterns to the outer one with thread at several points.

The inner part of a stencil is tied with thread.
This is the beginning of the use of silk screens.

In the 1910s, a person called Tsuneki devised a method of stretching silk over patterns, which came into wide use, and it led him to a great invention of photoengraving process with gelatin for which he took out a patent in 1917.
"Screen-printing" can sound like an overseas technology, yet what came from overseas is only the name. A man from Japan, who once was in USA, was interested in screen printing which is a great invention in Japanese textile printing, and introduced it as silk-screen process printing.

Screen-printing, begun in 1910s however, was declining in Japan in wartime without development. Yet after the war, it has made remarkable progress and has come to be widely used among the Electronics Industries Association for substrates or HIC, in harmony with the birth of NEWLONG's screen-printer.

Because the gauze, used for patterns for screen-printing, were originally made of silk, the printing was called silk-screen-printing.
