Zusammenfassung:	A method of decolorizing a dyed material in a predetermined pattern, which method involves providing a dyed material and ink jet printing a solution of an oxidoreductase onto the dyed material in a predetermined pattern. The present invention further provides a dyed material which has been decolorized in a predetermined pattern by a method of the present invention. The dyed material may be, for example, a dyed textile. Also provided is a method of simultaneously decolorizing and printing on a dyed material in a predetermined pattern. The method involves providing a dyed material and ink jet printing on the dyed material in a predetermined pattern with an ink jet ink which contains an oxidoreductase and one or more dyes which are not significantly decolorized by the oxidoreductase. The oxidoreductase may be, for example, a laccase, peroxidase, or diaphorase. If desired, the dyed material may be heated after printing the solution of an oxidoreductase or an oxidoreductase-containing ink jet ink thereon.
