Hints about which ICC profile and PDF/X standard to use.
<texcode>
gray rgb cmyk spot transp. notes
PDF/X-1a:2001 % PDF Version 1.3 (Acrobat 4.x) * * * *PDF/X-1a:2003 % PDF Version 1.4 (Acrobat 5.x) * * * *

* 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.

'''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).
