A SHORT time ago a manufac-turer came to us with a problem which we were able to solve to the advantage of the photographer and the satisfaction of the manufacturer, so it may be worth passing along.
The manufacturer exhibited a number of glossy prints which are used by his salesmen, and on the face of these prints he had attempted to have printed a short description of the article. Printer's ink didn't seem to hold to the gelatine surface and lifted off when the prints were placed on the ferrotype plates, so we were asked to suggest a way of overcoming the difficulty.
On questioning the manufacturer we found that his entire line of goods had already been photographed, and the new idea was to reduce all of the pictures to a smaller size. On each of these small pictures a description of the article was to be printed. This would be simple because the negatives were blocked out, making the backgrounds white.
The printed matter was necessary but it didn't seem practical for the printer to do the job with printers' ink. Could we solve the problem?
We could, but we couldn't do it with printers' ink. Possibly there is an ink that could be used but we do not presume to know the characteristics of printers' inks.
We told the manufacturer to secure the copy for the descriptive matter that was to appear on each photograph. This was set up in type and divided into paragraphs of the size wanted. The printer then made proofs on a good paper, getting a clean impression that could be photographed.
Negatives of the printed matter were made on Process Film to secure good opaque backgrounds, several paragraphs appearing on each negative. These negatives were then cut into strips so that the strip of printed matter could be attached to the negative of the piece of merchandise and the two bound together with opaque adhesive paper.
The negatives of the merchandise were trimmed so that the paragraph of printed matter came in the exact location desired, and a print from the combination negative was more satisfactory than could possibly have been the case had the job been done with printers' ink.
The above plan can only be used when a negative is blocked out, trimmed down, and the negative of the title attached to it.
It is much more simple to have a title appear on a dark portion of a print, the letters white against a dark background. We have described this method before but as we continually have requests for information as to how we place titles on sample prints, we will repeat the instructions.
The title is printed on a piece of transparent film support so a small printing press is required to secure an even impression of the type. A small hand press can usually be picked up in a second hand store. They are made for boys, are inexpensive and while toys so far as printing is concerned, are large enough for the average title for a negative.
One or two styles of very plain type, possibly in two sizes, will be sufficient for all ordinary purposes. The title which you wish to appear on the print is set up in type, locked in the form and placed in the press.
The press should be inked in the same way as for printing on paper, the ink being a fairly heavy, quick drying black printers' ink. Don't attempt to use any but printers' ink.
When you have made the press ready take an impression on a thin piece of paper to see that the type is properly inked and that there are no mistakes in composition. Then take an impression on the sheet of film support that is to be used on the negative.
This film support is known as Transparent Kodaloid and is made in several weights. The No. 1 which is very thin is most satisfactory for this purpose.
Cut a piece of Kodaloid slightly larger than your negative to allow for adjusting the title. Then print the title on the Kodaloid as nearly where you want it as possible. As soon as you have taken the impression and while the ink is still wet, dust finely powdered lamp black over the printing. Allow about five minutes for the ink to partially dry and remove the surplus lamp black by rubbing with a tuft of clean cotton.
After allowing a few minutes more for the ink to thoroughly dry, the Kodaloid is ready for use. The lamp black is quite necessary as the ink of itself is not sufficiently opaque to give a clean white letter. If more ink is used the letters will be smudged so it is best to use less ink and make it opaque afterwards.

To place the title on a film negative cut the Kodaloid exactly the size of the negative and bind the two together so that there will be no sliding motion to damage the lettering. If a great many prints are to be made from one negative it is best to attach the negative to a glass, place the Kodaloid over it and bind it to the glass with adhesive tape so that no dust can get under the negative.
In addition to its usefulness in supplying a means of titling negatives, Kodaloid is an excellent protection against scratching valuable negatives, and is extensively used for this purpose.
