Abstract
An apparatus for making multi-color silk screen prints on dimensionally unstable material such as T-shirts includes a platen, to which the shirt is adhesively affixed, that is removable from the remainder of the apparatus with a shirt attached to it without loss of registry between the shirt and silk screens carried by the apparatus when the platen is reinstalled on the apparatus. This permits moving the platen from one apparatus to another thereby printing more colors than would be possible with either apparatus alone. The apparatus also permits removing the shirt from the apparatus to perform a non-silk screen process between the printing of colors. In a preferred embodiment of the invention the removal of the platen is accomplished by dividing the platen into a bottom piece that is attached to the remainder of the apparatus and a top piece that is releasably attached to the bottom piece. Matching pins and holes in the platen pieces permit their separation and rejoinder without loss of registry, and also secure the two platen pieces immovably with respect to one another.
