Bruno, after a small change of your naked.pdf, I could sign it without that ugly warning: I added an empty Resources dictionary:
3 0 obj <</Parent 2 0 R/Contents 1 0 R/Type/Page/MediaBox[0 0 595 842]/Resources<<>>>> endobj and, of course, adjusted the offsets. http://itext-general.2136553.n4.nabble.com/file/n4168358/naked_RESOURCES.pdf naked_RESOURCES.pdf The Resources, BTW, are marked as required/inheritable in ISO 32000-1, there even is the hint: "If the page requires no resources, the value of this entry shall be an empty dictionary." Thus, the Reader is not entirely wrong to dislike your PDF. This is not the complete solution, though, as the page in naked_acrobat.pdf does have Resources. I suspect, though, that it, too, most likely disrespects the PDF specification in some way. Essentially we need a way to execute the tests the Reader applies to the signed document independent of the signing context, i.e. already to the unsigned document. In that case we could show the customer that their initial document already contains that "PDF content or custom content not supported by the current version of Adobe Reader."
