成品书尺寸为 170mm x 240mm。连续的黑色矩形仅显示文本周围的边界。是什么原因导致侧面和底部出现两条额外的单独线条？此外，是否可以显示逻辑页面所在的 A4 页面，以便可以看到裁切标记？
\documentclass{book}
\usepackage[showframe]{geometry}
\geometry{
paperwidth=170mm,
paperheight=240mm,
lmargin=12.5mm,
rmargin=12.5mm,
bindingoffset=12.5mm,
bottom=12mm,

额外的线条来自页脚和边距区域，因此 geometry 中没有 headfoot 和 nomarginpar。要查看裁剪标记，您需要在 crop 中指定比 geometry 中更大的纸张尺寸。而且由于我使用 pdflatex 而不是 dvips...
\documentclass{book}
\usepackage[showframe]{geometry}
\geometry{
paperwidth=170mm,
paperheight=240mm,
lmargin=12.5mm,
rmargin=12.5mm,
bindingoffset=12.5mm,
bottom=12mm,
noheadfoot,
nomarginpar
}
\usepackage[cam,center,pdflatex,a4]{crop}
\usepackage{lipsum}% MWE only
\parindent=0mm
\begin{document}
\lipsum[1-8]
\end{document}
