PROCESS OF MAKING EMBOSSING DIES.
No Drawing. Application filed August 9, 1927, Serial No. 211,853.
This invention is directed to a process of making embossing dies of the type used in the printing industry, being particularly directed to an economical and simple process for the production of the male die.
The process, generally considered, involves the use of a fibrous material, such for example as chalk board, the printing on the surface thereof of an inked impression of the cut or type of which the die is to be a replica fixing the inked impression; and then eliminating the fibrous material by chemical action, leaving the replica as a male embossing die capable of withstanding extremely hard usage and particularly serviceable through its simplicity and economy of production.
In the specific carrying out of the process, the operator places upon the bed of a printing press the type or cut or the like which the proposed die is to duplicate. After indi" eating this type or cut, an inked impression is impressed upon the platen of the press. Chalk board or like fibrous material of appropriate size is then fastened in suitable guides to the platen and the press operated, causing an inked impression on the reverse sides of the chalk board, one directly from the inked type or cut on the press bed and the other from the inked impression on the platen. Of course, this operation is carried out while the ink of the impression and plat en is still fresh.
The printed impressions on the chalk board are then covered with pulverized rosin and the chalk board subjected to heat until the rosin fuses with the ink of the impression. The chalk board is then immersed in a bath of chloride of lime, made up for instance of ten parts of water to one part of chloride of lime. While the chalk board is submerged in the chloride of lime solution, the operator brushes the chalk board with a soft bristle brush, for example a camels hair brush, the brush operation being continued un il substantially all of the chalk on the chalk board is removed.
The chalk board with the impressions is then removed from the bath and subjected to absorbent material, as blotting paper, to absorb practically all of the moisture. The chalk board is finally placed under pressure and allowed to dry.
In preparing to use the embossing die thus produced, the die resulting from the process just described is secured, as by glue, to the platen of the press and utilized to Renewed April 24, 1929.
form the female portion of the die in the following manner. A number of sheets of blotting paper or the like are secured to a board of appropriate size, there being sufficient blotting paper to provide a mass substantially type high. The board, secured in a printers chase, is then applied to the bed of the press. The press is operated to cause the male die to make an impression in the blotting paper and the parts are allowed to remain in this position until the female portion of the die is firmly fixed in the blotting paper.
The dies are then used in the ordinary manner for embossing and it has been found that due to the action just described, the male die is extremely hard and of long life, remaining sharp and clear and suitable for the usual embossing work.
It will be remembered that inked impressions are provided on both sides of the chalk board. This double impressionserves to prevent the die replica from being destroyed in the chemical treatment of the chalk board.
What I claim to be new is:
1. A process of forming an embossing die, consisting in, producing an inked impression of the matter to be duplicated on chalk board, dusting the impression with pulverized rosin, heating the board to fuse the rosin and ink of the impression, and subjecting the board to a treatment to dissolve the chalk.
2. A process for forming embossing dies, consisting in subjecting a chalk board to a press impression of the matter to be duplicated following the application of ink to such matter, covering the ink of the impression on the chalk board with pulverized rosin, heating the chalk board to fuse the rosin and ink, and subjecting the chalk board to a bath of chloride of lime to dissolve the chalk therefrom.
3. A process for forming embossing dies, consisting in subjecting a chalk board to a press impression of the matter to be duplicated following the application of ink to such matter, covering the ink of the impression on the chalk board with pulverized rosin, heating the chalk board to fuse the rosin and ink, subjecting the chalk board to a bath of chloride of lime, and brushing the chalk board while in the bath.
In testimony whereof I have afiixed my signature.
