Masking (Intrinsic)
This enables the ratio of dark to light modules in the symbol to b
approximated to 1:1 whilst minimizing the occurrence of
arrangements of close modules which would prevent efficient
decoding.
The QR bar code specific options should append the general part
of the two-dimensional bar code command (indicated by the
italicized characters, see “b - Two-Dimensional Bar Codes,
General Part” on page 48 for more information.

Masking Parameter Descriptions
Parameter Description
c Fixed data mode character set:
1 = Numerical data mode
2 = Alphanumerical data mode
3 = 8-bit data mode (JIS 0201)
4 = Kanji data mode (JIS 0208)
5 = Mixing mode (any of mode c1-c4, model
type 2)
Model 1 default = Most optimal alternative of c1
to c4.
Model 2 default = c5.
Internally during rendering the QR Code, the
mode can be switched within a bar code to
minimize the bit stream area. By using parameter
cn, the data mode character set is fixed.
m Model type is defined and unchanged within one
QR Code.
1 = Original version
2 = Enhanced version (recommended). Default.
