Hi Michael. 

For PrintColorModeWKV - Binary (unless someone has a better name for 
threshold black-and-white output)

The term "bilevel" or sometimes "bi-level", as in Joint Bi-level Image 
Experts Group (JBIG) is quite commonly used and the one we prefer. It may 
be difficult to garner a strong consensus, however, across the industry 
since several terms are quite interchangeable. 

Regards,
Harry

[MFD] Additions to well-known values,   plus the PrintColorMode job ticket 
element






All,

Based on our IPP Everywhere discussions for CUPS Raster, I propose the 
following changes to the well-known values schema:

ColorEntryWKV:

- Add AdobeGrayscale8, AdobeGrayscale16, AdobeRGB24, AdobeRGB48, 
sGrayscale8, sGrayscale16, sRGB24, scRGB48, Black8 (or K8), and Black16 
(or K16)
- Rename BlackAndWhite1 to Black1 (or K1)

ColorSpaceWKV:

- Add AdobeRGB, Black (or just "K"), Grayscale, sGrayscale (mapping of 
Grayscale to sRGB), and AdobeGrayscale (mapping of Grayscale to AdobeRGB)
- Add comment that RGB, Black/K, Grayscale, CMY, CMYK, and YCC are device 
color spaces. 

PrintColorModeWKV (was ColorWKV):

- Binary (unless someone has a better name for threshold black-and-white 
output)
- Grayscale
- Color


We can also uncomment the Color element in PwgCommon.xsd and rename it to 
PrintColorMode, using to PrintColorModeWKV.
