After dissolving, mix the two solutions, pour a little of the mixture on fine flannel, rub it over so as to evenly moisten the surface of the flexible support, wipe off with a second flannel using only slight pressure but rubbing briskly and with circular motion. When finished, the waxed surface should be perfectly even and quite free from streaks or other markings. The waxing should be done some considerable time before the support is required for use, and exposed to the free action of air to remove all trace of the solvents.
PAPER PRINTS WITH ORDINARY OR SLIGHTLY GLAZED SURFACE.
After removal from the pressure frame, the tissue is plunged into cold water with a piece of support slightly larger. After soaking the necessary time, the prepared surfaces are brought into contact under water, removed from the bath and placed upon any even plane surface, such as zinc, glass, etc., squeegeed into contact, blotted or otherwise treated to remove uneven dampness, and developed in warm water as in double transfer from rigid support, then slightly rinsed in alum solution and washed in clean cold water until all traces of bichromate are removed. After the transferring is done as before described, only the print on flexible support must be soaked in water until quite flat before bringing into contact with its final support.
PAPER PRINTS WITH HIGHLY GLAZED SURFACE.
The printed tissue after removal from the pressure frame is coated with collodion, for this coating allowance must be made in printing. A considerable reduction in temperature takes place and any moisture present in the air is condensed on the tissue, bringing into action the well-known effect of continued moisture, i.e., considerably increasing the depth of the print. Great care must be taken to coat evenly and to prevent the collodion running in streaks on the back of the print. When such streaks or unevenness of any kind are present, a corresponding dark line or lines will be found on the face of the finished print. Transfer same as for prints with ordinary surface. All prints from flexible support on paper with a highly glazed surface as well as those intended for transfer to ivory or opal are coated with thin collodion:—
| Enamel collodion | 2 | parts |
| Ether | 4 | " |
| Alcohol | 4 | " |
DOUBLE TRANSFER TO OPAL AND IVORY.
After development the print is allowed to dry, and as soon after drying as possible it is transferred to its final support, whether opal or ivory, by a solution of gelatine composed of the following ingredients:—
| Gelatine (fairly hard) | 1½ | ozs. |
| Water | 20 | " |
| Chrome alum solution (30 grs.) | 2 | " |
Soak the gelatine in the water until quite limp, dissolve by heat, then add the 30 grain chrome alum solution; roughly filter through two or more thicknesses of fine muslin into a flat dish on a water bath. After cutting the print to a size a trifle less than opal or ivory, place both print and final support in gelatine solution, allow print to stretch until quite flat, then bring them into contact under solution, squeegee and place on edge to dry. When quite dry, remove temporary support by inserting the point of a knife between the surfaces at the edge, wash with benzol or ether to remove all traces of the waxing solution. The print is now ready for the artist.
