Description

Patented in the German Empire on May 25, 1878.

Inventor photographed on chalk paper, which was made in the "known way" with gelatin solution is coated and on which coating another also "shown in a known manner" The images to be colored are coated and fixed with silver collodion solution same in the manner known in photographic.

These pictures on the surface are best colored with oil paints in such a way that only the notes are applied in a sketchy manner, as the further course of the process shows the photograph gives the drawing and finer shading.

After the colors have dried, the picture is covered with French retouching varnishes and glued with the colored side on the canvas wall.

The glue used for this consists of fresh quark and lime, but can also Retouchirfirnifs. can be used for this purpose.

The colored picture produced in this way is now between the paper and the canvas.

The chalk paper coated with gelatin solution is then washed off with lukewarm Water easily removed, whereupon the finished picture appears on the canvas wall.

Then the same thing is done with West Indian copallack to better evoke the colors overdrawn.

These pictures can be on sheet metal, wood, stone, glass and whatever, except on canvas another material can be transferred. The following procedure is used for this purpose.

If the material on which the photograph is to be transferred is dark in the Color is such as B. a black lacquered tea board, the photograph is on its colored side evenly coated with white paint, around the dark ground of the tea-board on which the photograph is to be attached, not to let it shine through. After drying the white color this is covered with a good adhesive varnish and if this has tightened something, the photograph is glued to the tea board.

After the lacquer has dried, the glued-on photograph is doused with lukewarm water, whereupon the chalk paper with the gelatin solution can be easily removed, while the colored photograph emerges clearly. Then you can give a lacquer coating over photography and tea board to protect the former against wear and tear. To protect washing off; It is noted, however, that spirit varnish must not be used for this varnish coating, as this would destroy the collodion membrane which forms the photograph. One can auclTcläs on sheet transferred image when this sheet has only received a coating of paint, burn into the sheet in the usual manner known in which the photograph can withstand heat up to 180 ^0C.

After the process described above, the photographic image remains as it is completely intact and therefore errors in modulation and drawing are completely excluded. The melting, the shine and the depth of the colors are of surprising effect in these pictures.
