For example it is often used to mask off areas of a design when using a photoresist to produce printing plates for offset lithography or gravure. It is also frequently used during screen-printing. Ulano also produced a yellow-(amber-)coloured masking film called Amberlith that was light-safe only for blue-sensitive emulsions. They discontinued ...
Photographic emulsion is a light-sensitive colloid used in film-based photography. Most commonly, in silver-gelatin photography , it consists of silver halide crystals dispersed in gelatin . The emulsion is usually coated onto a substrate of glass , films (of cellulose nitrate , cellulose acetate or polyester ), paper, or fabric.
Heat shield for silk-screen printing. These screens have a special emulsion. When heated, the emulsion is burned revealing silk screen. Paper Masters for alcohol copiers.

Screen printing is a printing technique where a mesh is used to transfer ink (or dye) onto a substrate, except in areas made impermeable to the ink by a blocking stencil.A blade or squeegee is moved across the screen in a "flood stroke" to fill the open mesh apertures with ink, and a reverse stroke then causes the screen to touch the substrate momentarily along a line of contact.

Carbon tissue is a gelatin-based emulsion used as a photoresist in the chemical etching (photoengraving) of gravure cylinders [1] for printing. This was introduced by British physicist and chemist Joseph Swan [2] [3] in 1864. [4] It has been used in photographic reproduction since the early days of photography. [5]
