Enhancing Labels
You can enhance your labels by changing such aspects as the
character size and slant, the space between characters and lines,
and the orientation and/or placement of the label on the page. To
effectively use these enhancements you should understand the
properties of the character cell. Refer to “Working with the Character
Cell” later in this chapter.
Character Size and Slant
You can change the size of the characters using the Absolute
Character Size and the Relative Character Size (SI and SR)
commands. The Absolute Character Size (SI) command establishes
the nominal character width and CAP height in centimeters and
maintains this character size independent of the location of P1 and
P2 or the page size. The Relative Character Size (SR) establishes
the nominal character width and CAP height as a percentage of the
distance between P1 and P2. Subsequent changes in the location of
P1 and P2 cause the character size to change with the SR command.
Changing the character size changes the size of the CP (Character
Plot) cell and proportionally changes the line width used in labels
(refer to AD and SD).
Note When the Shift In (SI) or Shift Out (SO) control codes are used to
select a font, the font size reverts to that font specified using the AD
or SD commands.
You can use the Character Slant (SL) command to slant the
characters at a specified angle in either direction from the left
vertical side of the CP (Character Plot) cell. The CP cell is
not altered.
Character Spaces and Text Lines
You can use the Extra Space (ES) command to automatically
increase or decrease spaces between all characters or lines.
For example, ES can be used to increase space between every
character in a label such as, MEMORANDUM), or to
increase or decrease space between every line of text (such
as double-spacing).
