Braille embossing of text styles

Text styles' means the appearance of a text when applied with bold, italic, underlined or strikethrough characteristics. In order to print the text styles in Braille, it is essential that the Braille table used for the preparation has the style fields appropriately enhanced and, in the Braille Settings, choose one of the two useful options in the "Print styles" box.

There are two ways of printing text styles: the Biblos method and the classic method.

The Biblos method is the complete system for printing in Braille all the styles that a text can have. In Biblos an innovative style marking has been conceived and used, to print the new characteristics of the text introduced with computer science.

In Biblos mode, the change of text style is indicated by the use of special prefixes. All special prefixes dedicated to styles can be customized by entering the properties of the Braille table used for preparation.

Some style combinations are not considered, or are brought back to more appropriate combinations. In addition to the four individual styles of bold, italic, underlined, and strikethrough, Biblos marks combinations of bold italic, bold-barrel, italic-underlined, and italic-barrel.

The marking of the styles is done before the change of style of the text by a double braille code, consisting of style prefix plus style code. The return of the text to the normal style is marked in the same way.

The classic method can only partially print text styles. Classical marking styles considered valid are italic and bold. The underlined style takes the code bold; the strikethrough style is ignored.

The classical marking uses the following special prefixes: bold, italic, bold italic and style prefix.

Classic style marking takes place in two ways: up to three words with the same style, each word is preceded by the code assigned to it. Over three words with the same style, the first word is preceded by two cells, the style prefix and the code, and the last word is preceded only by the style code.
