if you are producing relative colorimetric images you might want to get the sRGB-IEC61966-2-1_noBPC.icc form http://www.color.org. It's rendering intent is a match to relative colorimetric and it doesn't add black to your colors like the sRGB-IEC61966-withBPC.icc which is for perceptual colorimetric rendering intent. here's a quote from their web site with regard to the two profiles: Both profiles contain the standard linearized Bradford D65 to D50 chromatic adaptation tag (this tag was often not present in older sRGB profiles), and the media white point tag is set to D50 (as is required for ICC v4 profiles). This avoids the inappropriate color casts that older sRGB v2 ICC profiles frequently produced when the absolute colorimetric intent was used. Otherwise, the profile with BPC is similar to most common sRGB ICC profiles in use. The profile without BPC produces sRGB colorimetry in the PCS that is more accurate to what a viewer of a sRGB calibrated display will observe in the reference sRGB viewing conditions, especially the dark colors and black point. It should be used in situations where greater colorimetric accuracy is desired, such as for preview and proofing applications, and where CMM color rendering will be applied. Note that both sRGB profiles will produce the same results if BPC (only) is applied by the CMM. if you want to create a standard work flow, then all of your color devices need to carry the same color profile for srgb. cmyk depends on your printer and you need to get the color profile from them and install it in scribus, then you should have no surprises. and if you really want to get down and dirty, you can set your monitor to user defined and select 50% for RGB respectively. 50% gives as close to a middle gray as you can get without a color cast that the other profiles give you. industry standard is 5000K warm white. how many people do you know that view printed work under 5000K lighting anyway? It's got too much yellow for me and 9300K is too blue. if you shoot for a neutral monitor then the work you produce with the color profile from your commercial printer should give you what you want. there are those on the list that will heartily disagree with me, but the proof is in my pudding and i have had no problems with my set up and commercial printers. one printer i use doesn't care if the pdf is profiled for cmyk or rgb. when he prints my stuff digitally, it's very close to what comes off my epson and hp printers that i use for proofing. regards, dwain -- Dwain Alford P.O.
