Script typefaces are based upon the varied and often fluid stroke created by handwriting. They are generally used for display or trade printing, rather than for extended body text in the Latin alphabet. Some Greek alphabet typefaces, especially historically, have been a closer simulation of handwriting.
Script typefaces are organized into highly regular formal types similar to cursive writing and looser, more casual scripts.
A majority of formal scripts are based upon the letterforms of seventeenth and eighteenth century writing-masters like George Bickham, George Shelley and George Snell. The letters in their original form are generated by a quill or metal nib of a pen. Both are able to create fine and thick strokes. Typefaces based upon their style of writing appear late in the eighteenth century and early nineteenth century. Contemporary revivals of formal script faces can be seen in Kuenstler Script and Matthew Carter's typeface Snell Roundhand. These typefaces are frequently used for invitations and diplomas to effect an elevated and elegant feeling. They may use typographic ligatures to have letters connect.
Casual scripts show a less formal, more active hand. The strokes may vary in width but often appear to have been created by wet brush rather than a pen nib. They appear in the early twentieth century and with the advent of photocomposition in the early-1950s their number rapidly increased. They were popularly used in advertising in Europe and North America into the 1970s. Examples of casual script types include Brush Script, Kaufmann and Mistral. Some may be non-connecting.
Script typefaces place particular demands on printing technology if the letters are intended to join up like handwriting. A typeface intended to mimic handwriting, such as Claude Garamond's grecs du roi typeface, will require many alternate characters. In digital type these (once drawn) can be substituted seamlessly through contextual ligature insertion in applications like InDesign, but this was complicated in metal. Another complexity in metal type was that sorts had to have delicate overhanging parts to interlock. This required careful design and casting for the sorts to fit together without gaps or the sorts breaking. Florian Hardwig, an expert on typesetting, has noted that in Germany in the twentieth century business needs led to the introduction of a more rugged style of script typeface without overhangs, in which gaps were filled in by the natural spread of ink on paper.
