RESE
I, EDWARD WILLIAM PARKES of 3 Salters Hall Court in the City of London
Gentleman do hereby my invention to be as follows:-
According to this invention after having taken a negative in the ordinary way, and
produced a positive either by the carbon or other similar process I immerse the print
in cold water and place it in contact with a temporary support for development after
which it is allowed to dry and the pellicle receives the required colors in flat tints
(either oil or water colors) these colors being first suitably prepared i.e. if oil colors
are used I add sufficient Balsam of Canada megilph opal, mastic varnish or other
similar medium for causing the colors to flow freely and evenly or in the case of water
colors I employ sufficient oxgall or similar medium for a like purpose.
A permanent support of paper sized and starched is then affixed to the pellicle by
damping the paper sufficiently to cause the pellicle to adhere to it.
The pellicle and paper are allowed to dry thoroughly and then stripped from the
glass the result forming a permanent and highly finished photograph in colors.

Improvements in the Production of Colored Photographic Pictures.
I EDWARD WILLIAM PARKES of 3 Salters Hall Court in the City of London
Gentleman do hereby declare the nature of this invention and in what manner the
same is to be performed to be particularly described and ascertained in and by the
following statement :-
According to this invention after having taken a negative in the ordinary way and
produced a positive either by the carbon or other similar process I fix the same with
the reverse side of print on glass, opal, porcelain, egg shell glass, or other similar
material as a support which has been previously waxed or French chalked and collo-
dionized. I prefer opal, egg shell, glass or porcelain inasmuch as the photographic
printer can the more readily discern the quality and various shades and tones of the
print required insuring more general similarity of light and shade when a number of
copies is required and the painter or colorist can the more easily trace the lines and
depth of color required without the assistance of a paper support desk or other
accessory thereby securing more accuracy of detail in colors. Again, the eggshell
glass and finely grained opal or porcelain impart to the photograph a very artistic
and highly finished appearance saving the labour and expense of rolling as usually
adopted with photographs on paper or similar substances. The print is then developed
on such support after which it is allowed to dry and the pellicle receives the required
colors in flat tints (either oil or water colors) these colors being first suitably prepared
i.e. if oil colors (which I have found preferable) are used I add a substance to bind
the colors that is to prevent the colors from running into one another and the medium
I have found answer best in practice is three parts best terebene one part pure mastic
a few drops of oil of turpentine thinned with ordinary spirit of turpentine. At times
I add amber and best copal varnish in proportion of 1 to 12 or japanned gold size
diluted with oil of turpentine. In the case of water colors being used I employ
sufficient oxgall or similar medium for a like purpose.
I have found oil colors more suitable to my process as I can lay the colors more
flatly and evenly and infuse the color into the film by means of the fleshy part of the
fingers or by using a stippling brush pad or similar contrivance the brush having a
tendency to cause uneveness and irregularity in the substance of the color and
destruction of the film which must necessarily destroy the value of the photograph.
I then pour over the film and color slightly warming them, a solution composed of
and proportioned as follows:-one part of borax dissolved in twelve parts of boiling
water to which I add an equal quantity of varnish made of white lac or similar
substance and methylated spirits in the proportion of 1 to 3. This operation fixes
the colors and removes all greasiness of oil colors and bubbles, pimples and peeling
off of the film which otherwise occurs when the transfer is effected without this
precaution. If japanned gold size with oil of turpentine has been used in the earlier
part of the process the use of the fixing solution may be dispensed with unless the
colors employed are of a vegetable character when it should still be applied. A

page_text: permanent support of paper sized and starched or the ordinary transfer paper is then
affixed to the pellicle by damping the paper in cold and warm water alternately
sufficient to cause the pellicle to adhere to the said last mentioned support.
The pellicle and paper forming the support for the pellicle are allowed to dry
thoroughly and then stripped from the glass and mounted on cardboard, opal, glass,
porcelain or other similar suitable strong and permanent support the result forming a
permanent and highly finished photograph in colors.
Having now particularly described and ascertained the nature of my said invention
and in what manner the same is to be performed I would remark in conclusion that
I am aware of several attempts having been made to produce colored photographs by
painting on the back of a carbon or other pellicle and by afterwards stripping the
colored pellicle from the supporting glass but all such attempts have proved practi-
cally unsuccessful but what I claim as my invention and desire to secure by Letters
Patent is :-
The improved method substantially as hereinbefore described for the production of
colored photographic prints on a carbon or other equivalent film.
