Tsume reduces the space around a character
(but not the character itself) by a specified percentage value.
When tsume is added to a character, spacing around both sides of
the character is reduced by an equal percentage.
If you’re working with an existing layer, select
the text layer in the Layers palette and then select a type tool.
Select the characters you want to adjust.
Click the Show Asian Text Options button in
the options bar. If you don’t see the button, make sure that preferences
are set to show Asian type options.
Select a percentage for Tsume from
the pop‑up menu, and press the Enter or Return key. The greater
the percentage, the tighter the compression between characters.
At 100% (the maximum value), there is no space between the character’s
bounding box and its em box.
Note: An em box is a space whose height and width roughly
correspond to the width of the letter “M” (also called a mutton).
