The print to be toned should first be washed thoroughly. Place it in the Bleaching Bath, and allow it to remain until only faint traces of the middle densities are left and the black of the shadows has disappeared. This operation will take about 1 minute.
Note: Particular care should be taken not to use trays with any iron exposed, otherwise blue spots may be formed on the prints.
Rinse thoroughly in clean cold water.
Place in Toner Solution until original detail returns. This will require about 30 seconds. Give the print an immediate and thorough water rinse; then immerse it for 5 minutes in a hardening bath composed of 1 part of Kodak Liquid Hardener or two parts of Kodak Stock Hardener F-Sa and 16 parts of water. The color and gradation of the finished print will not be affected by the use of this hardening bath. Remove the print from the hardener bath and wash for one-half hour in running water.
