[ What is claimed:] [1.] A method of drying a monolithic substrate having a coating media within a plurality of channels comprising:a) removing a first end of the coated monolithic substrate from a bath containing the coating media while the coating media is in a wet condition;b) applying a vacuum to an opposed end of the coated monolithic substrate at an intensity and for a time sufficient to draw vapor out of said channels while forcing a gas stream through the substrate from the first end in the direction of said opposed end without substantially changing the coating profile within the channels.
