Check Standard Em Space to specify an em-space equivalent to the point size of the text
(for example, 24pt text has a 24pt em space). If Standard Em Space is unchecked, the
application uses the width of the two zeros in the current font as the em-space width. This
option is checked by default. You can insert an em space in text by pressing
Option+space/Ctrl+Shift+6.
Use the Flex Space Width field to change the 50% default width of a flexible space. To
create a breaking flexible space, press Option+Shift+space/Ctrl+Shift+5; to create a
nonbreaking flexible space, press Command+Option+Shift+space/Ctrl+Alt+Shift+5. The
Flex Space Width value is expressed as a percentage of the normal en space for a given
font and font size (range = 0 to 400%, measurement system = percentage, smallest
increment = .1).
Use the Accents for All Caps check box to specify whether to include accent marks on
accented characters with the All Caps type style applied. This option is checked by default.
Use the Space between CJK & R field to indicate how much space should be included by
default between a Chinese, Japanese, or Korean character and an adjacent Roman character.
Preferences — Trapping
The Trapping pane (Administration > Preferences > Renderer > Trapping) includes the
following controls.
Select a Trapping Method:
• Click Absolute to trap using the values in the Auto Amount and Indeterminate fields
according to the object and background colors involved. If the object color is darker, the
object is choked by the background using the Auto Amount value. If the object color is
lighter, the object is spread into the background using the Auto Amount value.
• Click Proportional to trap using the value in the Auto Amount field multiplied by the
difference between the luminance (lightness or brightness) of the object color and the
background color.
• Click Knockout All to turn off trapping and print objects with a zero trap amount.
Check Process Trapping to trap each process separation plate individually when a page
contains overlapping process colors.
Check Ignore White to specify that an object color in front of multiple background colors
(including white) does not take white into account when trapping.
Enter a trapping value in the Auto Amount field or choose Overprint:
• Enter a value in the Auto Amount field to control the amount of trapping that QuarkXPress
applies to object and background colors that have an Auto Amount specified in the Trap
Specifications dialog box (Edit > Colors > Edit Trap), and to control the amount of
trapping applied to items with an Auto Amount (+) Trap Information or (–) specified
in the Trap Information palette (Window > Trap Information).
