The male die having been formed and hardened by cooling due to cutting off the current through the heater, the material to be embossed is laced Y y the, roo pressure of the female die thereon. i

In`Figs. 4 and 5, aspreviously-.described, the laten"1,`-flat or cylindrical, asthereo'n the eatand- .current insulator 2, the heater 3 in` circuit 'with'the'fwires 4,` and the layer V5 of m5 A or the like on the heater.. Top'rovide .ama e-ready 'for the form 7 that .sha lhave the'congurationof the face .thereof witho'u l the-open spaces, there printing-form 7 is brought into contact, the

plastic material is brought to the form 5,

constituting the leveler, and the paper thereon is brought to theforms 8 and 9, constituting the packin having the congurations of the face o the form. The current being cut off, the bodyA of the make-ready thus formed sets and the surface for supporting the material to be printed is now pro erly level and, if desired, the layer 9 may e removed.

It will be understood that the make-ready must be formed upon the platen, because of the practical difficulty of producing it otherwise and because'the irregular character of printing-surfaces is such that it would beimpracticable for the purposes of this invention to operate in any other manner.

H aving described our invention, we claim- 1. The method of constructing a makeready which consists in supporting a substance upon a platen, and there heating' said .substance to plasticity, molding it to the general configuration ol' a form used for making an impression, and hardening it by cooling.

2. AInake-ready composed of a substance rendered plastic by heat and hardened by cooling, a support for said substance, a heater for softening said substance, an insulator between said support and heater, and a form for molding said substance to the configuration required for properly supporting amaterial to be impressed.

3. A make-ready composed of a substance rendered plastic by heat and hardened by cooling, a press platen or cylinder, a heater for softening said substance, an insulator between said platen and heater, and a form which molds said substance substantially to its own configuration and impresses a material supported on said molded form. i 4. A make-ready composed of a substance softened by heat, means for heatin said substance, a form for molding said su stance, a packing of paper, and a sheet of stiff material to prevent soft composition owing in open spaces between type or in the face of the form.

In testimony whereof we have hereunto y set our hands, this 14th day of November,

1905, in the presence of the subscribing witnesses.
