Manipulation For Transfer Process. Having provided the necessary materials as instructed under the heading of "Materials Required," proceed as follows: Place a sheet of transfer paper a little larger than the print to be used, face upward, in a dish of clear, cold water, and allow it to soak two minutes for smooth paper and ten minutes for thick, rough paper. Next, take the adhering sheet of sensitized pigment tissue and the print (prepared as instructed for the Non-Transfer Process), and immerse in the same tray. After a few seconds' soaking, the paper may be easily separated from the print by a steady pull from one corner.
Note. In this case the pigment gelatin of the tissue will adhere to its own support, leaving the print uncovered and changed from black to a light brown color. The pigment tissue now represents the exposed tissue in ordinary carbon printing, with the immense advantage that the image is reversed as regards right and left, thus securing an unreversed picture by a single transfer.
396. Place the print in a tray of cold water preparatory to re-development, retaining the sheet of pigment tissue in your hand while examining the transfer paper for air-bells, which are likely to accumulate after the operation of stripping. After having removed any air-bells on the transfer paper by brushing with a large camel's-hair brush, bring the surfaces of the pigment tissue and transfer paper together under the water; then lift them out, clinging together, and lay them upon some smooth, hard surface, such as a sheet of plate glass, and squeegee them into contact with a flat squeegee.
397. Next, place them between blotters under moderate pressure; a sheet of thick plate-glass makes an excellent weight for the purpose. At the expiration of twenty minutes, development may be accomplished as described in the Non-Transfer Method.
Mounting. After the print is dry it should be placed on a flat, smooth surface, face down, and the back moistened with water (applied with a soft sponge or tuft of cotton) until the print has become limp. Care should be taken that the water does not reach the face of the print. The back may then be covered with paste and the prints mounted in the usual manner.
How To Re-Develop A Print That Has Been Used For The Transfer Process. After the print has been separated from the sheet of pigment tissue it should be washed for fifteen minutes in running water and then re-developed in any developer suitable for bromide or developing-out paper as the case may be. Continue development until the image changes to deep black; then wash for twenty minutes in running water.
400. The developer should be of full strength and preferably without bromide; allow the print to remain in the developer for several minutes after it has assumed a good deep black. It is impossible to over-develop. The re-development may be accomplished in daylight and no fixing is necessary. The print is now restored to its original condition and efficiency, and may be used again for printing after drying.
401. With care, as many Ozobrome pictures can be made from one print as the strength and substance of the paper base will allow.
