"Prints should be air dryed for six hours. (There are quick methods that recommend drying with heat, but most bromoilists over the years have recommended air drying for the beginner at bromoil. The quick method is for expert bromoilists.) After the prints have dried slowly in the air, they can then be superdried. If you have a dry mount press, preheat it to 250° and press the print between two matte boards for 2 or 3 minutes. You can also move the print over a gas stove burner on medium heat for 20 to 30 seconds. This drives all remnants of moisture out of the print and leaves it bone dry--it is also said to soften the gelatin and make it take ink more easily. Superdrying is done again to the matrix just before it is soaked for inking. If you live in an area where the humidity is very low, superdrying can be omitted. However, if you live in an area where the humidity is very high, I strongly recommend superdrying."
Preliminary Notes on Bromoil, Ed Buffaloe, unblinking eye
"When inking is complete leave to dry for a couple of days and then finish.
Any white spots can be re-inked or spotted. Dark areas can be lightened with a pencil rubber or scraped with a scalpel to insert highlights."
