User–Defined Variable Bar Code Ratios [R[D]ratio]
The user–defined variable ratio for bar codes is an optional parameter. The
default ratios shown in Table 5–2 through Table 5–9 are overridden by the
variable ratio feature. Four- and eight-digit ratios can be used, depending
upon the bar code selected. Ratio data must be decimal values greater than 0.
Enter R, followed by the actual bar code ratio. A colon must separate each
element of the ratio.
Like standard bar code ratios, user–defined ratios are also interpreted from
left to right, measuring the size of each bar or space, in dot width, in the
following pattern: narrow bar : narrow space : wide bar : wide space. Either
enter four or eight values depending upon the bar code type.
If the 'D' parameter is specified, the ratios are represented in printer dots
instead of IGP PGL dots (60 x 72 dpi).
NOTE: The IGP/PGL does not verify that ratio data creates acceptable

wide/narrow element relationships for bar code readability. When
designing unique ratio data, carefully plot wide and narrow ratios to
conform to readable bar codes.
