It is important that the design embossed in the leather be as permanent as possible. In this regard both the structure of the skin and the type of tannage are important. A very full and tight structure is required. Calfskin gives the ideal structure for the finer leathers and cowhide for the coarser. Vegetable tannage is far superior to chrome because it builds up the fibers to a much greater extent and makes the structure correspondingly tighter.
Embossing of leather is sometimes (and perhaps frequently) a means of simulating the grain pattern of a superior leather on an inferior and/or less expensive skin. An example of this would be a calfskin embossed in imitation of MOROCCO .
2. The process of imparting a raised or depressed design in paper: 1) by passing the paper between an engraved steel roll or plate and another roll or plate of a soft or compressible material, such as paper or cotton; 2) by pressing the paper between strong, coarse fabrics; or 3) by passing the paper between etched male and female iron or steel rolls. The operation is used to create decorative effects and is generally applied to book, blotting, or cover papers. Plate or spot embossing is a method by which individual designs, as distinguished from all-over patterns, are embossed. This technique is accomplished by means of vertical presses, the paper being embossed by placing it between the embossing die and the counter or make-ready of the press and forcing it into the intaglio areas of the die.
3. To impress the marks of ownership into a page of a book by means of a device employing a sunken die and a raised counterpart which raises the design above the paper. See also: PERFORATING . (2) 4. To block the title, author, or other bibliographical information, on the cover of a book. See also: BLOCKING (1) . 5. See: BLIND BLOCKING . (94 , 189 , 233 , 234 , 264 )
