PRINTING-OUT PAPERS.
Printing-out papers are so called because, unlike a negative, the image appears without development, and they require only toning and fix ing. Printing-out papers are simple to handle, and are popular with both professionals and amateurs. Indeed, nearly all of the paper used by pro fessional photographers in the United States is a printing-out paper of the brands which this booklet will instrua you in using.
Solio and Kloro are Gelatino-Chloride papers. Aristo Platino and Aristo Self-Toning are Collodio-Chloride. With the former the silver chloride and other salts are held in position in gelatine, while with the latter they are held in position in collodion.
Of the many papers offered, one of the most desirable, for the beginner at any rate, is a gelatino-chloride (chloride of silver in an emulsion of gela tine) printing-out paper. In the printing-out paper the image " prints-out " at once. Before it is toned and fixed it is in the same condition as a proof received from the photographer. The chemical a&ion clears the high lights and shadows, gives the proper tone and " fixes" the print, 1. e., makes it permanent.
The process of toning and fixing may be combined in one bath or may be done separately. For convenience we recommend the combined bath to the amateur, but care should be exercised not to overwork the bath. This bath will continue to give satisfaaory tones long after the gold has been exhausted. This toning without gold, however, is not permanent and no attempt to economize by overworking the toning bath should be made, as disappointment will be the inevitable result.
Keep your paper in a dry place. Do not expose it to moisture or the fumes of coal gas, it being very sensitive to either.
When you have taken the print from the printing frame it is still sen sitive, containing, as it does, most of the original silver chloride, and should you expose it to the light it would soon blacken all over. Keep your prints, after removing from the printing frame, in a dark box until you are ready to tone. Handle as little as possible and do not allow the fingers to come in contact with the surface of the paper.
Open the printing frame and lay the negative back down upon the glass* (the back is the shiny side). Place upon this a piece of Solio paper, face down. Replace the back of the frame and secure the springs. The back is hinged to permit of uncovering part of the print at a time to inspect it without destroying its register with the negative.
The operation of putting in the sensitive paper must be performed in a sub dued light, that is to say, in an ordinary room, as far as possible from any window. The paper not used must be kept covered in its envelope.
The printing frame, when filled as directed, is to be laid glass side up in the strongest light possible (sunlight preferred) until the light, passing through the negative into the sensitive paper, has impressed the image sufficiently upon it. The progress of the printing can be examined from time to time by removing the frame from the strong light and opening one half of the hinged back, keeping the other half fastened to hold the paper from shifting. The printing should be continued until the print is a little darker tint than the finished print should be.
As soon as the print is finished place it in a drawer or box where it will be protected from the light until your batch of prints is ready for toning.
For the combined bath the printing should be carried about two shades deeper than you desire the finished prints to be as they will lose considerable in toning and fixing. For the separate bath about one shade deeper.
Prints will keep three or four days before toning, providing they are stored in a dark box.
For one just starting to tone prints, we would recommend the combined bath. This will be by far the most simple in manipulation (the toning and fixing being done in one bath) and with proper attention to the instruCtions you should be able to secure prints of a soft, rich tone, ranging in color from a warm Sepia to a dark purple. Solio Combined Toning and Fixing Solution may be had of any Kodak dealer.
