Some XSL-FO formatters use 'grayscale' psedo profile for this: http://mediawiki.renderx.com/index.php/XEP_User_Guide/Appendix_A_XSL-FO_Conformance#Color_Specifiers But I take it rather as a syntactic sugar for CMYK: 0,0,0,blac(K). However, if I understand correctly, CSS gray is sRGB based and hence potentially problematic for printing when transformed to device profiles. I like the approach of pseudo Gray/CMYK profiles as they allow me defining exact values which are preserved (in the PDF output) without profile conversions. So when I define gray, it is printed as shade of black instead of RGB composition. Btw, as non native speaker I am very often confused by grey/gray mess and it is unclear which one to use ;-) Would 'lightness' be misleading here? Jan
