New Caslon, introduced in 1905 by Inland, was the most successful of [the attempts to regularize Caslon and improve its so-called faults] In addition to eliminating irregularities, the aim of this typeface was to strengthen the design so that under modern printing conditions it would more closely resemble the effect of the original Caslon when printed heavily on dampened rough paper, as was commonly done in the eighteenth century. The italic followed in 1906. In 1919 ATF (successor to Inland) reversed the descender-shortening trend with the design by Morris Benton of long descenders, oldstyle figures, and italic swash characters as American Caslon; otherwise this typeface and New Caslon are identical. New Caslon was adapted to Linotype and Intertype as Caslon No. 3, which some users call Caslon Bold, although it was not intended to be a bold face. However, in 18-point and larger, Caslon No. 3 and Italic are copies of Caslon Bold rather than New Caslon.”

Digital versions include Linotype’s Caslon 3 and Bitstream’s Caslon Bold. E+F and Scangraphic’s New Caslon is a revival of a different typeface, possibly Caslon 540.
