Issues with crop marks

Question

I'm using the template of a journal, which can be found here: https://www.overleaf.com/latex/templates/review-of-financial-studies-latex-template/bdgcyvpjqmbc

The header is supposed to have two images in the corners.

I think the code for the images is as follows:

\begin{picture}(0,0)\unitlength\p@\thinlines
  \put(-30,0){\circle{10}}
  \put(-30,-5){\line(0,1){10}}
  \put(-35,0){\line(1,0){30}}
  \put(0,30){\circle{10}}
  \put(-5,30){\line(1,0){10}}
  \put(0,35){\line(0,-1){30}}
  \end{picture}}

However, when I compile (for example directly on overleaf, or in texniccenter, or in texstudio) the images don't show up. Instead, I get the text that corresponds to the code, in an overflown line.

Any idea of what may be going on and how to fix it?

Thank you in advance.

Answer 1

The two small images (actually there should be four) in the corners are crop marks. Your attached image looks very like the cam crop mark created by crop package.

In the following example, the printed area is a4paper (set by geometry package), but the physical area is 250mm x 337mm (which is wider and higher than printed area by 40mm, respectively).

\documentclass{article}
\usepackage[showframe]{geometry}
\usepackage[cam,center,width=250mm,height=337mm]{crop}

\usepackage{blindtext}

\begin{document}
\blinddocument
\end{document}
