peated, back and forth, until the design of the die hasbeen transferred to the roller in the required depth.

The roller is then removed, hardened, and burnished.It is now ready to perform its function as indicated byits name—the "transfer roll." Once the roller is back inposition in the transfer press, with a suitably preparedplate of soft steel placed under it in the positionformerly occupied by the die, it now becomes possible to"lay down" the design on the transfer roll to the plateas many times as may be required. Hence the singledesign of the die may be repeated on a larger plate in-definitely, limited only by the size of the plate itself.After the transfers are completed, the plate is hardened,burnished, and ready to print.
