This is a colour process using a regular pattern screen developed by George Sydney Whitfield of Paget. A separate screen is used allowing the negative to be processed in the normal way and for the transparency to be made by contact printing. A different screen, with modified colours, was used for viewing the transparency. The process was introduced in 1913, re-introduced following World War I and discontinued around 1925. From 1925 the old-established firm of C. Baker in Holborn advertised a very similar process. The process had a speed of around 15 Watkins, F24 Wynne.

The method of producing the screen was patented in 1908, other related aspects such as the use of a registration device on the screen and the production of prints were also patented.1

The colour screen consisted of red, green and blue squares with twice as many blue squares as red or green. J.H. Pledge measured the squares as being, on average, 1/400 inch for the side of the blue square and 1/300 inch for the green and red squares.2

For a short period around 1914 a combined plate version was sold as was a process for producing paper prints.

In use a panchromatic plate is exposed behind the Taking Screen. After development a positive plate is made, by contact printing, which is viewed in register with the Viewing Screen. Special plates were sold by Paget for the negative and positive plates. A light filter was used over the lens when making the original exposure.

The image on the right shows the colour screen, taken with a microscope magnification of 48x.
