1000×1000 character design spaceFigure 7-1.

Other type foundries, however, oen use a dierent design space for CJKV-specic

glyphs. 0,−200 to 1000,800 has been widely used by many CJKV type foundries, such as

Changzhou SinoType Technology, Seoul Systems, SoMagic, and Yoon Design Institute. I

have also encountered font data that used the following design spaces:

0,−110 to 1000,890—Monotype Imaging•

0,−130 to 1000,870—EulHae•

0,−160 to 1000,840—Fontworks•

0,−166 to 1000,834—Hanyang Information & Communications•

High-end, page-layout applications, such as Adobe InDesign, automatically calculate the

ideographic em-box of all fonts so that glyphs will be placed correctly relative to one an-

other on the line, and on a character grid. Such applications also allow the user to adjust

the baseline and size ratios in order to better adapt Latin fonts for use with CJKV charac-

ters, which is done in the context of dening composite fonts.

So, when does a dierent baseline adversely aect typography? When mixing fonts whose

glyphs are set in dierent design spaces. is is when it is critical that an OpenType font

includes a well-specied ‘BASE’ table that explicitly species the relative position of design

space. Without a well-specied ‘BASE’ table, applications are forced to use heuristics.
