Special thanks must go to the '''Ghent PDF Workgroup (GWG)recommendations: '''for making a list of recommended profiles.

Updates about GWG
More info will be made available at a later date.
First things first. The following parameter must should be set for any PDF/X version.
<texcode>
The two parameter '<tt>format</tt>' and '<tt>intent</tt>' are sufficient for most cases.
The '<tt>format</tt>' parameter simply defines the '''PDF/X version''',while the '<tt>intent</tt>' parameter sets the so called '''output intent'''.
Currently the following PDF/X versions (enter without quotes) are supported:
<code>format =</code>
* PDF/X-1 uses device dependent colors, i.e. your pictures must be converted into the output color space (gray or CMYK).
* PDF/X-3+ uses device '''in'''dependent colors, i.e. the color space of your pictures doesn’t matter, but it must be defined by a color profile.
* It makes no sense to use CMYK pictures with PDF/X-3+, because color conversions between CMYK profiles are more lossy than any RGB-to-CMYK conversion!
* It makes sense to use PDF/X-1a:2003 for bw printing.
* Even if they’re allowed in X/4+, don’t use PDF layers for print projects – your printshop will not be able to handle them.
Predefined output intents (also without quotes):

'''Which one to use?'''
* In Europe, use FOGRA profiles.
* In the USA, use SWOP profiles.
* In Japan, use Japan profiles.
* Use Coated for image printing paper.
* Use Uncoated for natural paper (e.g. "offset").
* "Web" means "web offset", i.e. big volume printing from a roll of paper (vs. sheet paper).
Some examples:
'''All remaining parameter are kind of special.'''
sets the ICC based default color space profile (option for color management);
this setting is document wide and currently only one profile
per color space is allowed
sets the PDF compress level (values of 0..9 are allowed). Normally no need to change the
default value.

This list contains the profiles recommended by the [http://www.gwg.org GWG] (Ghent PDF Workgroup)in 2008,
the set of profiles bundled with [http://pages.cs.wisc.edu/~ghost/ ghostscript]
and three test only profiles from the [http://www.color.org ICC] (International Color Consortium).
Nearly all predefined ICC profiles are also available in the download section.
Output intents are bound to very specific printing conditions (which vary worldwide),
so it's it’s very likely that you only need one or two ICC profiles (and not all of them).Therefore the profiles are also available as profile ZIPs come in 'localisedlocalized' versions.

All profiles in the zip archive are already located in the correct sub path,
so you only have to unpack them right in your ConTeXt directory
(normally '<tt>texmf-context'</tt>).
In case you use these profiles also with other software, it is
E.g. for Adobe Acrobat on Windows Vista this special directory is
<code>'C:\Program Files (X86)\Common Files\Adobe\Color\Profiles\Recommended'</code>
Store the needed profiles there (without any tex directory) and
set $OSCOLORDIR to that path.
All you need now is a final '<tt>luatools --generate' </tt> to update the file database.
In case of problems you should add
And that's it for the moment...
