the color conversion. Therefore, the data arrives at the printer already color–managed

NOTE:

These options have no effect if the software defines its own CMYK space, known as

calibrated CMYK or CIEBasedDEFG in PostScript terminology.

RGB color emulation

These options apply to PDF, PostScript, TIFF, and JPEG files. For HP-GL/2 and RTL files, only sRGB and

AdobeRGB are supported.

color profiles:

None (Native): no emulation. The printer uses its default internal conversion from RGB to CMYK,

without following any color standard. This does not imply that results will be bad.

sRGB IEC61966-2.1 emulates the characteristics of the average PC monitor. This standard space

is endorsed by many hardware and software manufacturers, and is becoming the default color space

for many scanners, printers, and software programs.
