Short Form of CID Command (Configure Image Data)

The Short Form of the CID command involves sending just the common 6-byte header. By changing the value of byte 0 (color space), the short form can specify the following five color spaces:

•Device RGB ?*v6W[0x00, . . . ]

•Device CMY ?*v6W[0x01, . . . ]

•CIE L*a*b* ?*v6W[0x03, . . . ]

The following data ranges are allowed in CIE L*a*b*. Hue is preserved when out-of-range data is clipped.

L* = 0.0 to 100.0

a* = –100.0 to 100.0

b* = –100.0 to 100.0

CIE L*a*b* color space support is at HP Color LaserJet level for HP Color LaserJet 5 and 5M printers.

• Colorimetric RGB (SMPTE RGB) ?*v6W[0x02, . . . ]

Non-linear SMPTE RGB with a 2.2 gamma and 1.0 gain is the default Colorimetric RGB color space. The short form allows the following ranges:

R = 0.0 to 1.0

G = 0.0 to 1.0

B = 0.0 to 1.0

HP Color LaserJet 5 and 5M printers bypass the Colorimetric RGB process. In place of it, a device-dependent RGB process is substituted with a Screen Match color table.
