Crop box determines what is visible when the file is opened in a .pdf viewing program, usually 0. Bleed box determines the amount of ``bleed'' which a file has, which is what is printed beyond the trim area so as to allow printing to go up to the trim and ``bleed'' off. Given modern printing equipment 1/8" (9 bp) is typical --- the metric equivalent usually rounds down to 3mm. Trim box determines what the publication's final size will be after it is folded (if necessary) and cut. Here's some code which I worked out w/ the help of the list to make a file w/ a trim box: \documentclass{minimal} \usepackage[paperwidth=630bp,paperheight=810bp]{geometry} \usepackage{atbegshi} \AtBeginShipout{\special{pdf: put @thispage <</TrimBox [9.0 9.0 621.0 801.0]>>}} \pagestyle{empty} \special{pdf: put @thispage <</TrimBox [9.0 9.0 621.0 801.0]>>} \begin{document} Test \newpage Test \end{document} HTH!
