Final Drying And Flattening. For final drying and flattening, first lay a dry blotter on a smooth, level surface; covering the blotter with prints face down. Cover this blotter with white cardboard, placing another layer of prints on the cardboard, but face side up; then cover

See Paragraph No. 365 these prints with a dry blotter. Continue in this way, first a blotter, then a cardboard, always having the face of the print next to the blotter and the back to the cardboard. You can stack a large number of prints in this way, and after all have been placed between cards and blotters, place a level board or sheet of glass on top and weight it down. Allow them to remain under weight over night. The prints will dry evenly, and when removed they will not only be dry, but perfectly flat.
Caution. It is essential that chemically pure blotters are used for this purpose, as poor blotters might result in spots and stains. Blotters are supplied especially for this purpose by the photographic stock houses, manufactured with a view to photographic requirements. After the prints are dried they should then be embossed as follows:
Embossing Device. As this device is cheaply constructed, one should provide himself with numerous sizes covering different size openings. For a cabinet size opening proceed as follows: Take two heavy 10x12 cardboards and from the side of one cut off a strip one inch wide; then take a piece of adhesive tape and paste this strip back in place, making a hinge on this board, numbering it No. 1 (See Illustrations 6 and 7). Next cut an opening 4 1/4x6 lengthwise, and 3% inches from lefthand side and equal distance from top and bottom. Number this 4 1/4x6 piece which you have cut out of No. 1, No. 3. Paste a 10x12 sheet of good strong manila paper to lefthand edge of card No. 2 as it lays with the wide side at your left, and paste this paper so it will only adhere about-one inch. It will then open and shut like a book. Paste the hinge of card No. 1 on to card No. 2, by placing the hinge of No. 1 even with the left and wide edge of No. 2. The sheet of manila paper should be between the two cards. When paste is dry, lay the book down, No. 2 on the bottom. With a sharp penknife, first cut out the paper between the cards that show in the opening in No. 1. Then take the small card (No. 3) and cut 1/8 of an inch from one side and one end. Apply paste to one side of this small card and fasten it to No. 2 iv - 8 within the opening in No. 1, so there will be an even space on all sides 1-16 of an inch.
