IMITATION STEEL DIE STAMPING

Many wrappers for candy boxes, jewelry boxes, etc. have the business card die-stamped upon them, the stamping being done from steel dies on power plate printing and die stamping presses. During the last few years, however, a special process has been perfected for producing imitation steel die stamping and embossing on regular platen printing presses from type forms or line engravings.

This new process calls for special printing inks and powders, and also for a patented machine on which the freshly printed sheets are “powdered” and heated, causing the printed subject to stand up in relief in the same way as steel die stamping or embossing. Numerous box-makers are now using this process in connection with the work of printing box wrappers of the better grade.

With this process the sheets are first printed in the same manner as ordinary printing, in black, color, gold or silver, using the special compound instead of ordinary printing ink or size. As the sheets are printed they are fed one at a time into the powdering hopper of the patented embossing machine. In the hopper is a granulated resinous compound which adheres to the printed detail. As the sheets are taken from the hopper they are placed on a conveyor which carries them through a heating oven, fusing the powder with the ink, and causing the printing to raise like embossed or die-stamped work. The entire operation is very simple and the results are satisfactory.

There are several patented “imitation” embossing processes now in use and one of the most efficient is that supplied by A. Stokes & Co., of Cleveland, Ohio. This machine is called the “Stokes’ Process Embossing Machine, Model C,” and it will handle sheets up to 17 inches wide. The Stokes Co. furnish complete instructions and all inks, powders, etc., necessary for this process.

One of the best printing ink reducers on the market is called “Reducol,” made by the Indiana Chemical and Manufacturing Co., of Indianapolis, Ind. Reducol is particularly adapted to all kinds of printing inks used on glazed paper.
