[Tex/LaTex] PDFLaTeX Color Space

acrobatcolorpdftex

Background

Am using TeX Live 2012, pdflatex, and latexmk to produce the document, on Ubuntu Linux.

Problem

In the following image, Okular is shown on the left and Adobe Acrobat Reader is shown on the right.

Okular vs Acrobat Reader

The images in the document most likely contain various colour spaces. The colours in Okular are desired (and shown as coded in the LaTeX); whereas, the colours in Acrobat Reader are not desired.

I have read a few different questions on this topic, including:

PDF colour model and LaTeX

Question

What is most likely the problem with the colours in Adobe Acrobat Reader, and how should I resolve it?

Ideas

I was thinking that the problem might be caused by having images in multiple color spaces. If that's the case, then I could resolve it by running the images through ImageMagick.

The alternative is to use xcolor, as suggested.

Best Answer

The following lines were added to the preamble:

\RequirePackage[xcolornames,svgnames,dvipsnames,rgb]{xcolor}
\pdfpageattr {/Group << /S /Transparency /I true /CS /DeviceRGB>>}

This seems to have resolved the problem.

[Tex/LaTex] How to annotate PDF files generated by pdflatex

Okay jumping on the old horse! ;-)

Meanwhile Acrobat Reader X offers some simple possibilities for PDF annotations. If you want to do more you can use the pdfcomment package, e.g. for your examples:

\documentclass[a4paper]{article}
\usepackage[latin1]{inputenc}
\usepackage[T1]{fontenc}
\usepackage{lmodern}
\usepackage[rgb]{xcolor}
\usepackage[author={Max Schlepzig}]{pdfcomment}
\begin{document}
Here we\pdfcomment[color=red,icon=Insert]{insert: miss} a word!

You can do much more \pdfmarkupcomment[markup=Squiggly,color=green]{with pdfcomment}{move to the front}.

This is a \pdfmarkupcomment[markup=StrikeOut,color=red]{stupid}{replace stupid with funny}  game!

\pdfmarkupcomment[markup=Highlight,color=yellow]{Of course, you can highlight complete sentences.}{Highlight}

This is very\pdfcomment[icon=Note,color=blue]{insert graphic!} interesting!
\end{document}

[Tex/LaTex] How to overcome Acrobat Reader error 131 with a pdfLaTeX doc

I solved a similar problem by generating a PDF 1.4 only with pdflatex using \pdfminorversion=4. I'm also only using png's and 1.4 pdf images in my latex document. It worked before with evince but now acroread also reads the file just fine and I preserve the same quality level. The ghostscript workaround resampled my images to jpeg which derogated the quality.
