Abstract
A moveable shield and associated liquid containment system which may be used with machines in which arrays of individual streams of liquid dye are used to pattern substrates. The shield associated with a given array selectively may be interposed between the substrate and the liquid dye streams of that array to prevent substrate contact by the liquid streams as, for example, during cleaning operations, or withdrawn to permit unimpeded substrate contact by the liquid dye stream. One or more arrays may be cleaned or charged with a different color dyestuff while the remaining arrays are used to pattern the substrate, eliminating the down time presently associated with the cleaning or dye changing of individual arrays.
