Production Powders Become a Concern

Powders used within the printing process, obviously, have never been an issue until now. Known generically as offset spray powders and slip agents, the powders, such as those manufactured by Oxy-Dry, are used to prevent pages from sticking together while drying, or to keep the books from adhering to polywrap bags. Consequently, quantities of these powders remain in between the pages of books after they have been mailed and have been known to spill out of the pages upon opening, causing concern for uninformed readers.
