# Error creating pdf/a with latex

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

\usepackage[a-1b]{pdfx}


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

where I should copy it after having downloaded? –  Mazzy Dec 21 '12 at 21:31
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
