I'm trying to create pdf/a through latex. I inserted in my tex file the package:


with the option a-1b but I got error:

pdfTeX error (ext5): cannot open file for embedding ...eam attr{/N 4} file{sRGBIEC1966-2.1.icm}
\pdfobjcompresslevel > 0 requires \pdfminorversion > 4. Object streams disabled now.

I don't really know what does it mean


This is a color profile. Printers need them to correctly print color pdfs. There are a number of profiles on the net.

You can find this file here: https://github.com/bencomp/pdfx-ext/blob/master/sRGBIEC1966-2.1.icm

    The simplest way is to put it in your working directory, where the .tex file is – Boris Dec 21 '12 at 21:32
  • Ok the error has gone...but I got another error: Option clash for package hyperref. \def. What does it mean? – Mazzy Dec 21 '12 at 21:34
  • you probably call hyperref with some options that conflict with those provided by pdfx package. Try removing the options from \usepackage[OPTIONS]{hyperref} – Boris Dec 21 '12 at 21:46

    use \hypersetup after calling the packages. – Boris Dec 21 '12 at 21:50
