440. Printing

Printing. Prints should be printed the same as for plain gold toning; about two shades darker than the finished print.

441. Washing

Washing. Wash prints in two changes of clear water and immerse in the following bath for five minutes:

Water........................................

100 ozs.

Salt..........................................

3 ozs.

Then wash in three changes of clear water and tone in a bath made up as follows: 442. Gold Bath. -

Water.........................................

.64 ozs.

Aristo Gold, No. 2.............................

.. 1 dr.

Uranium Nitrate.......................................

.3 grs

Salt...........................................

60 grs.

Add enough carbonate of soda (saturated solution) to turn red litmus paper blue in five seconds.

443. This bath should be made up about one hour before using. Should the bath tone too slowly, add enough gold to keep toning speed from five to six minutes. Tone prints to the exact color you desire them when finished, and transfer them from the toning bath into the following check bath:

Water.............................

100 ozs.

Sulphite of Soda (Saturated Solution)........................

. 1 oz.

444. After all prints are toned, wash them in three changes of clear water, and fix in the following bath for 20 minutes:

445. Hypo Bath

Hypo Bath.

Water........................................

100 ozs.

Sulphite of Soda (Saturted Solution)..........................

.. 1 Ozs.

Hyposulphite of soda, enough to make bath 15 hydrometer test.

446. From fixing bath throw prints into strong salt bath to prevent blisters, then wash through 12 to 15 changes of clear water, handling prints thoroughly in each wash water, or wash under a sprayer for 20 minutes, handling constantly, then lay out to dry.

447. Note. (a) Owing to the extra weight and thickness of the paper the chemicals are not easily washed out. Care and thoroughness in the washing are necessary.

448. Note. (b) Prints should be toned to the exact color desired, as the check bath holds the tone, and prints properly handled will dry to the color they were when removed from the gold bath.

449. Note. (c) Handle prints constantly in hypo bath to insure thorough fixing.

450. Note (d) Should the check bath after toning show a tendency to carry the prints back to a warmer tone than when they left the gold bath, reduce the sulphite one-half. The difference in water and in the conditions you are working under, in many places, may have a tendency to give the prints a slightly warmer tone, if they are left in this bath over 10 minutes.

451. Note (e) Soft, brilliant negatives, full of detail, give the finest sepia prints.
