I recently had a book printed, where I used fading lines in the header. In the PDF it looks correct, bu in the actual print, the lines on the left pages didn't fade as much as the lines on the right pages, so the lines seems "cut" (apologies for blurred pictures):

The code is, I think, identical, so I can't understand why..? This is how it looks in the PDF:

And an MWE:

\documentclass[11pt, titlepage, openany]{book}

\usepackage[textwidth=13cm, left=3cm, bottom=2cm, top=2.5cm, headsep=1.1cm, paperwidth=20cm, paperheight=27cm, layoutwidth=19cm, layoutheight=26cm, layouthoffset=0.5cm, layoutvoffset=0.5cm, showcrop, asymmetric]{geometry}
\usepackage{fancyhdr} 
\usepackage{tikz} 
\usetikzlibrary{fadings}
\usepackage{lipsum} 

% Headers
\definecolor{gray}{cmyk}{0,0,0,0.4}
\definecolor{darkgrey}{cmyk}{0,0,0,0.6}

\pagestyle{fancy}
\renewcommand{\chaptermark}[1]{\markboth{#1}{}}
\fancyhead{} % Remove head fields
\fancyfoot{} % Remove foot fields

\setlength{\headheight}{24pt}
\fancyhead[RO]{\sffamily\bfseries\footnotesize\textcolor{gray}\leftmark\hspace{0.3cm}\sffamily\bfseries\normalsize\textcolor{darkgray}\thepage}
\fancyhead[LE]{\sffamily\bfseries\textcolor{darkgray}\thepage\hspace{0.3cm}\sffamily\bfseries\footnotesize\textcolor{gray}\leftmark}
\renewcommand{\headrulewidth}{0pt}
\renewcommand{\footrulewidth}{0pt}

\renewcommand{\headrule}{%
\vskip-\baselineskip\vskip4pt
\ifodd\count0\hfill\begin{tikzpicture}
    \fill[darkgray,path fading=west] (0,0) rectangle (4.98,0.02);
\end{tikzpicture}\else\begin{tikzpicture}
    \fill[darkgray,path fading=east] (0,0) rectangle (4.98,0.02);
\end{tikzpicture}\fi}

\begin{document}

\chapter{Test chapter}

\end{document}

Any help would be deeply appreciated.

  • It looked fine when I printed it. Maybe the problem is in your printer. – John Kormylo Apr 25 '16 at 13:22
  • Sorry, I should have specified that it's the actual book print that is the problem. Regular prints from the PDF are fine. – Lars Nersveen Apr 25 '16 at 17:23
  • Old versions of Postscript interpreter can't render fadings... Your printer probably uses an old PDF / Postscript interpreter. – Paul Gaborit Sep 17 at 21:34
