Bell Gothic and Bell Centennial, commissioned for telephone directories, are notable examples of this. Small-print designs often feature a large x-height, and a chunky design. Some fonts used at such sizes may be members of a larger typeface family joining members for normal sizes. For example, the Times New Roman family contains some designs intended for small print use, as do many families with optical sizes such as Minion. In the metal type era, typefaces intended to be printed small contained ink traps, small indentations at the junctions of strokes that would be filled up with ink spreading out, maintaining the intended appearance of the type design. Without ink traps, the excess ink would blob and ruin the crisp edge. At larger sizes, these ink traps were not necessary, so display faces did not have them. They have also been removed from most digital fonts, as these will normally be viewed on screen or printed through inkjet printing, laser printing, offset lithography, electrophotographic printing or other processes that do not show the ink spread of letterpress. Ink traps have remained common on designs intended to be printed on low-quality, absorbent paper, especially newsprint and telephone directories. A sentence that uses all of the alphabet (a pangram), such as "The quick brown fox jumps over the lazy dog", is often used as a design aesthetic tool to demonstrate the personality of a typeface's characters in a setting (because it displays all the letters of the alphabet). For extended settings of typefaces graphic designers often use nonsense text (commonly referred to as "greeking"), such as "lorem ipsum" or Latin text such as the beginning of Cicero's "In Catilinam". Greeking is used in typography to determine a typeface's "colour", or weight and style, and to demonstrate an overall typographic aesthetic prior to actual type setting. The process of printing typefaces has historically been far simpler than commissioning and engraving custom illustrations, especially as many non-text features of printed works like symbols and borders were likely to be reused by a printer in future. Non-character typefaces have therefore been created for elements of documents that are not letters but are likely to be reused regularly. These include:  Ornamental (also known as "novelty" or sometimes "display") typefaces are used to decorate a page. Historically complex interlocking patterns known as arabesques were common in fine printing, as were floral borders known as fleurons evoking hand-drawn manuscripts.
