when was silk screen printing invented?

Answer 1

"Silk Screening or Serigraphy
In 1907, Samuel Simon of Manchester England was awarded a patent for the process of using silk fabric as a printing screen. Using materials other than silk for screen printing has a long history that begins with the ancient art of stenciling used by the Egyptians and Greeks as early as 2500 B.C. A few years after Simon's patent, John Pilsworth of San Francisco developed a multicolor process of silk screening called screen printing. The term "Serigraphy", comes from the Latin word "Seri" (silk) and the Greek word "graphein" (to write or draw)."
