Preparation of Color Slides Using Heat Shrinkable Material

This method of preparing projector slides uses transparent plastic material which is capable of being stretched into an expanded form when cold and which shrinks to its normal size when heated.

A plastic sheet having the dimensions of a 35 mm. projector slide may be expanded when cold to a standard letter sheet size (8 1/2'' x 11''). The desired graphic representation is painted or printed upon the sheet in this blown-up form, using any desired colors. The sheet then is heated in an oven at moderate temperature until it has shrunk to its original size. It is then ready to be mounted for use as a slide.

The transparency image or artwork can be very accurately prepared upon the enlarged sheet. There is no need to transfer the image from one medium to another. Original colors are preserved in the reduction. The process can be performed quickly.
