If I were doing art prints, I would place Xara's art and the color managed images into something else.

In the case of an image containing an embedded ICC, couldn't a program like Acrobat use the ICC to convert the color values such that the resulting file would not need an embedded ICC profile in a given color space? If I understand it correctly, programs like Photoshop have to do that transparently anyway in the work space (otherwise process color formulas wouldn't work).
That brings up some questions I have about Xara's color handling. When a CMYK color model is used in DPX and the image exported in CMYK, I am assuming that the color values are preserved rather than the color (50% C in the Colo Editor is exported as 50% C in the CMYK image). If a color is specified in the RGB color model, its values appear to be preserved as well (rather than converted to the CMYK color space to preserve the represented color). This makes sense as it is completely blind to color space, but it seems to make the color models of little value (unless you need to specify exact K values since pure RGB neglects K). Is this correct? I was exporting a TIFF in PGD9; is it different if I were to export a PDF/X (I'm guessing not)?
Lastly, do any of you have suggestion on how to handle colors within the CMYK gamut that are outside a specific printer's gamut? Would professional printers know (or have a good idea) of what process colors are not producible on their presses? As I understand it, this is where the printer's ICC profile would be used for proofing in Acrobat.

Years ago when I was a very new art director working on the Datsun (now Nissan) national advertising account, I did my first color ad with a photo of two Datsun automobiles. We spent weeks working with the photo engraver preparing the color separations for the full page ads that were running in Life and Time magazines. Finally the color proofs we saw were as close to the 8 x 10 transparencies are they were ever going to get.
I have to wait about two months before the ad appeared. I looked at the ad in Time Magazine in horror. The white car was all pink. I showed the ad to my wife who looked at it, shrugged her shoulders, and said, what's the problem, it looks fine to me.
In other words, it was convincing.
Unless you are printing catalogs and ads in which customers are making a critical selection based on color accuracy, just make sure the printing is clean and you'll be OK.
That might work for you, but I am a tedious artist and designer (traditional and digital). I choose my colors carefully. While minor shifts are to be expected, I desire colors as accurate as possible (especially if I decided to get into art prints in the future). It is important enough to me that I would work exclusively within the intersection of the color spaces throughout my work flow (printer, CMYK, sRGB) if needed (using trial and error or a tool like Gamutvision).
Re: Xara Designer Pro X9 - Workflow for Accurate Prints?
Xara doesn't use an ICC profile as far as I can tell. ICC profiles are valuable for a color managed work-flow as regards to soft-proofing on your monitor in order to match output intents. But they do not change color values. They are also used for hard-proofing a printer that is capable of having a profile made specifically to match the output intent...but how many here have a printer capable of using that profile? Even if one does have a printer capable of profiling, you need a profile for each and every output intent.
Output intents, as used in the PDF creation and inside Acrobat, are what need to be matched. But internally, Acrobat only uses monitor ICC profiles and again, only if you can have an ICC profile made for your monitor. This color management is way outside the purview of the thread and really doesn't apply to XDP as it is not a color managed application.
For images that are going to press, I use PhotoLine and tweak curves, etc., in order to get specific CMYK proofing. Those are placed in XDP and remain relatively accurate through a PDF work-flow. I'll whip up some examples later. Currently, while monitoring the threads I am currently involved in (here and elsewhere), I am helping my son work on his car's motor.

Re: Xara Designer Pro X9 - Workflow for Accurate Prints?
From the acknowledgments in PGD9:
Some import and export filters (including PDF) utilize color profiles from Adobe Systems Inc. The license agreement can be found in the Filters\pdfxfilter\icc folder of your Photo & Graphic Designerinstallation.
The license agreement just says that the profiles may only be distributed when embedded within files.
Xara doesn't manage color; it is in the sRGB color space by default as a result. Xara has to use those Adobe profiles for importing and exporting CMYK content. The imported or exported CMYK file must have an embedded ICC profile or it wouldn't be CMYK. If Xara truly does not support color management at all, it must use the ICC profile to transform the file to the sRGB color space (without the need of an embedded profile any longer). A CMYK-specific import feature wouldn't even exist otherwise.
If I had a camera that I profiled, Xara would not be able to load the profile. But, I may be able to embed that profile into an image using an external application (know of any applications?). However, would Xara's input filters transform the color correctly if the profile was for the sRGB color space rather than CMYK? If it did have an embedded CMYK profile, would Xara transform the image based upon the image's embedded profile or based upon a packaged CMYK ICC profile from Adobe after determining that the image had a CMYK profile?
If Xara transforms (not interprets) the colors of imports using embedded profiles, Xara should be quite friendly to color managed work flows. (I don't have the tools to test this, or I would have.)
If it doesn't work that way, such functionality should be relatively easy to implement as an extended input filter using Windows Color Management API (not requiring any modification to the core Xara engine as implementing a full color management system into Xara may require).
For export, Xara seems to embedded a profile only for CMYK files, maybe using an Adobe profile for SWOP rather than Windows RSWOP.icm. Moreover, Xara applies no transformation to the exported file, preserving all color values.
Then, a program (such as Acrobat) would use a printer's ICC profile as an output intent to soft-proof the CMYK image for a specific printer (alternatively a standard CMYK profile could be used). The printer's ICC profile technically wouldn't be needed if it was calibrated AND supported the full CMYK color space. And, yes, it would also need the monitor's ICC profile to be accurate.
At this point a program (such as PhotoLine) may be needed to adjust CMYK curves for values not set by the user in Xara to tweak ink densities. The values I'm talking about could be from photographs or from raster graphics generated by Xara effects (such as transparency).
I feel like I'm beating this topic to death, so I hope you're bearing in there with me. :) I've read a lot of complaints from Adobe users about Xara's lack of color management. Especially from what I've heard from most of you here, I think Xara could have a place in a very cost-effective workflow that would be just as good for accurate print colors as Adobe's workflow (except be more user-friendly).

I have priced tools for creating a profile for a printer and calibrating it, and they cost several thousand USD. For a desktop printer, profiles may be applied through Windows Color Management (or Mac's equivalent). In such a case, you'd have to make sure that the printer's driver is not also attempting to assign a profile. I have an HP officejet printer, and even it installed a default profile for itself. Windows lets you assign multiple profiles as you do need one for each paper type you plan to use and such. That proofing still requires that the printer be calibrated (instead of your monitor). I could see it being necessary if working in a color space larger than the monitor supports.
Hope your son has a good time with his car. :)
Re: Xara Designer Pro X9 - Workflow for Accurate Prints?
I tend to agree with Gary here, are we not getting too involved with the technical issues here? printing doesn't have to be that involved to look good. The stuff that I did up to recently, at least 5 different newsletters per week with a mix of content, once a month a large run on 1 brochure and maybe a poster from the brochure, were all dependant on having a good relationship with the print house. If there was a problem with any of the files I got a quick or made a quick call to and from the print house. The only thing that got past was twice we had some smears on a run which were small scratches on one of the films and that was over a period of five years. Not all of the files were done in Xara as AI and ID were used but all of the newsletter done using Pro which was most of my work. With the mix of content in the newsletters there was a slight loss in gamut when printed but that was expected as the bitmap was never taken into PS and just relied on the RIP to produce an acceptable halftone pattern. What I am really saying here is that having a printer that you can rely on is more important than how good my design's are so long as I have followed a few simple rules when producing the file, like total ink percentages, transparencies/bitmap effects should be flattened, correct use of blacks, text should be placed at the top of the stack/top layer....... there are a few more.

i agree with you
i am a mere novice in matters of pro print
i cant and dont want to get my head around most of it
so i have always had to rely on the print houses professionalsim and honesty
if you have a serious and helpful account mananger
and a relationship where evertybody accepts they may have made a mistake (incredible how such a little thing can ruin an entire contract)

Re: Xara Designer Pro X9 - Workflow for Accurate Prints?
Austin - I am not exactly an amateur. I just have a more realistic approach to printing. I have had my work published in about 10 books, plus my stereogram partner and I have contributed to a Japanese stereogram magazine that has over 30 issues. The color is going to turn out how it is going to turn out. And with very rare exceptions, it is fine.
Whenever you print a multi-page document, your image will be influenced by whatever else is on the sheet before it is trimmed out and bound. In the case of my white car taking on a pink tinge, I was able to isolate the other ad on the signature and it had a lot of red in the image.
If you are a perfectionist and want to make your color as accurate as is humanly possible, more power to you. I tend to spend more time concentrating on the creative end of the project. :)
