I have just upgraded to PDFCreator 1.7.0 and it tells me
PDFCreator now produces PDF/A 2b output
However Adobe Reader, when it encounters a PDF/A file, normally says:
The file claims compliance with the PDF/A standard
but I am not getting this displayed when I open a file generated by PDFCreator 1.7.0. How can I be reassured that my file really is PDF/A?
