PLANNING YOUR FORMS
Font character maps
Once the compiler equates a keyboard code point to a Xerox
character identifier, another translation must locate the graphic
representation of the character within the font.  A font character
map identifies the location of each graphic character within a
font.  The graphic representation is the actual bitmap that prints
the character in the form.  Usually the character is in ASCII
format.  For example, hexadecimal code point 41 is the ASCII
code for the uppercase A.
Some character sets may not support all font graphic characters.
For example, Character Set E does not contain the left brace ({).
For more information on font character maps, see the “Virtual
keyboard and font character maps” appendix in the

Adding color to forms
The Xerox highlight color LPS printers and the Xerox 4700 Color
Document Printer allow you to use color to emphasize important
parts of your form.  With a highlight color printer, you can use
different shades of a single color to highlight parts of your form.
The 4700 printer uses full color technology, which allows you to
choose from a wide selection of colors. The following examples
show typical color enhancements for forms: 
Highlighted titles
Highlighted columns representing totals or important results
Lines setting off groups of columns or items or used as a
border for your form
Boxes filled with any of the colors and tints available in the
ink catalog.
You use the HFDL command statements to control color.  For
more information, refer to the “Using HFDL commands” chapter.
On a highlight color printer, text, lines, and box borders always
print in the primary color of the printer, even if you specify a
different color, tint, and so on.
You can send a form using red, blue, or green palettes to either
a highlight color printer or a full color printer.  To convert red,
blue, and green highlight colors to full color versions, recompile
the form with VERSION=XC on the COMPILE command.  The
full–color palette is available only on the 4700 printer.
Ink color availability and control
When planning colors, you should determine if your company
has any regulations and controls for using colors on forms.  You
may need to use a specific ink list, which contains an ink catalog,
palette, and ink for items such as logos and form titles.  Contact
your System Administrator to determine the available ink colors.
