Print space

As set mirror the usable area is designated on the page of a book, magazine, or other printed works in typography. The type area is bounded by the lands, so the unprinted distances between the mirror and the edge set. The columns ( columns ) with text, graphic or image always belong to the set level. The so-called " running heads ", which contains along with the page number also brief details of the relevant chapter content, calculated at the rate levels; as footnotes. In contrast, the part of "dead running title ", which only contains the page number, not the type area.

The art of record is the design of the page in a form or in a relationship, so that it appears to the viewer harmonious. To achieve this most subjective goal, the printing crafts of various rules and systems operated to achieve the desired result. Among other things, the dimensions of the golden ratio and related numbers of the Fibonacci sequence can be used, but over the centuries, various other classifications. It is essential to ensure that a particular division scheme for the page is valid only for a particular page size of the paper. As a rule the lands fall to the middle of a book is narrower than at the edge, since there touch the sides and thus have the two inner webs looks more like a double-wide unit.

Thus, for example, in the Middle Ages when paper with the side ratio 2: 3 times a ratio of gutter: head web: outer web: footbridge of 2: 3: 4: 6 is used in paper 3: 4 and 3: 4: 6: 8 Microsoft Word and other word processing programs use, however, in the preset for A4 paper a rather mechanical ratio of 5: 5: 5: 4 or 4: 5: 5: 5 ( " book" ).

Example

Layout Construction of a double-page spread with the aspect ratio of pages of 1: √ 2 (DIN format):

Structure ( phase 2)

Construction according to the golden section

For an A4 double side, thus results in the following distances:

Grid spacing

The page is horizontally and vertically divided into the same number of grids. At the inner and upper edge of each of a grid remains free at the outer and lower two.

Webs

The edges between type area and paper edge hot lands. The respective web has its own name, so there is no confusion between the edges.

• Top margin: head web
• Outer edge of the sheet: outer web
• Middle of the book, on the Bund: Gutter
• Bottom margin: footbridge
