1240. Mounting

Mounting. In multiple mounting the print and mounts should be tacked only at the top - not pasted solid. Trim the first section to suit the print and tack the print to this section, pasting the upper edge only. Place it under a weight while trimming the remaining sections. After all are prepared the print and first section are tacked to the remaining sections in proper order.

1241. When all the layers are mounted, the whole is placed in correct position upon the table to remain under pressure until dry.

1242. Stock Mounts

Stock Mounts. The various manufacturers of card mounts supply a large variety of stock mounts for solid mounting, as well as folders to which prints are merely tacked at the upper edge. The solid mounts are usually employed for printing-out papers and ordinary weight gaslight papers. The folders, soft or flexible mounts, are used more for platinum prints. Illustration No. 33 shows a variety of mounts of good proportion and color for solid mounting, while illustration No. 34 gives an idea of artistic folders. The mounted studies reproduced in this library furnish excellent examples for mounting and spacing.

1243. Dry Mounting

Dry Mounting. A most convenient and practical method of mounting is the so-called "dry mounting." The Eastman Kodak Company have placed on the market a Dry Mounting Tissue, which they claim has solved the mounting problem. They also make an apparatus to be used in connection with the tissue. (See Illustration No. 35.) However, prints may be mounted without the special apparatus, as they advise "Just press with a hot iron - that's all." (See Illustration No. 36.)

1244. If a print is mounted wet it must, of course, be expected that more or less curl will result unless the mount is of sufficient thickness and weight to resist the pull of the print. Mounting on a thin mount with paste means curling. It would, therefore, seem that the most successful method, under all conditions, would be dry mounting with heat to secure contact. Dry Mounting Tissue does away with every objectionable feature of all other methods, permitting the mounting of prints of any size on the thinnest mount without curl. The pressure of a hot iron begins and completes the operation. The tissue is put up in all standard sizes, from 3 1/2 x 3 1/2 to 8 x 10, and is also sold in 5 yd. lengths, 20 inches in width.

1245. The method of mounting is to lay the print on its face and attach to its back a piece of mounting tissue the same size, or a little larger, than the print. Do this by applying the point of a hot iron to small spots at opposite ends. Turn the print face up, trimming it and the tissue to the desired size. Lay in correct position on the mount. Cover with a piece of smooth paper and press the whole surface with a hot flat-iron. Press down; do not rub. The iron should be just hot enough to sizz when touched with the wet finger. If the iron is too hot the tissue will stick to the mount and not to the print. If the iron is too cold the tissue will stick to the print and not to the mount.
