In my document I'm using the colour lightgray which looks nice on screen, but is barely decipherable when printed (with a BW-laser-printer). Using the xcolor pkg:

  • Would it make sense to try and convert lightgray with \convertcolorspec to a cmyk equivalent for more legible printing results?
  • Would this necessitate choosing a darker colour, or could a cmyk 1:1 equiv. of lightgray be chosen that looks exactly like the original lightgray on screen ?
  • If so, how to code it?

A pretty plain MWE:

\documentclass{article}

\usepackage{lipsum}

\usepackage{xcolor}

\begin{document}


\lipsum[6]

{\textcolor{lightgray} {\lipsum[3]}}

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
%%%%%% Some more or less random snippets from the xcolor manual %%%%%%%%
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
% \extractcolorspec{lightgray}\tmpa
% \expandafter\convertcolorspec\tmpa{cmyk}\tmpb
% \expandafter\convertcolorspec\tmpa{RGB}\tmpc

% {\textcolor{\extractcolorspec{lightgray}{\tmpa\expandafter\convertcolorspec\tmpa{cmyk}\tmpb}}{\lipsum[2]}}

% \convertcolorspec

%%%%%%%%%%%%%%%%%%%%%%%%%
% Colors via svgnames option

% LightSlateGray
% LightSlateGrey

% Silver
%%%%%%%%%%%%%%%%%%%%%%%%%

% - enhanced color definition syntax to allow for target-model specific color parameters, e.g., \definecolor {red}{rgb/cmyk}{1,0,0/0,1,1,0}, facilitating the usage of tailor-made colors both for displays and printers;
