PROVISIONAL SPECIFICATION.
An Improved Method of Producing Coloured Photographs.
I, HERBERT WILLIAM COTTRELL, of 176, Ashstead Row, Birmingham, County
of Warwick, Photographer, do hereby declare the nature of this invention to be as
follows:
-
This invention relates as hereinafter described to an improved method of pre-
paring coloured photographs and has for its object to provide means of producing
photographs having a coloured, or tinted background; thereby an effective and
artistic appearance is obtained at a low cost of production. My invention con-
sists essentially in a method of producing specially prepared sensitive paper or
material upon which are various tints or designs. Upon this paper the photo-
graph is printed, toned, and fixed or developed in the ordinary way.
In carrying my invention into practice I take sheets of ordinary paper and print
thereon by a lithographic process and any well known means various coloured
or tinted designs according to requirements. The said sheets are then covered
with any sensitising medium and cut to the usual size. The printing is done by
arranging the negative and sensitive paper in the printing frame, and toned or
developed in the usual way which produces a beautiful and artistic effect.
My invention is applicable to any paper or material capable of being covered
with any of the known sensitising mediums or materials.
Dated this 14th day of October 1897.
