The PDF document can be created by LaTeX or OpTeX or ConTeXt or something else. Then use this plain TeX macro for creating additional crop-marks. Prepare following TeX file. Its name can be crop.tex, for example, but its name cannot be cropmarks.tex, becuase this is the macro file. -------------------------------- \input cropmarks \def\document{name} % the name of the PDF file without extension \def\info{} % info text printed in the top (in crop area) \hmargin=10mm % added left+right margins from the document border to the sheet border \vmargin=10mm % added top+bottom margins from the document border to the sheet border \mlenght=5mm % lenght of the crop-mark abscisses \gap=2mm % distance of crop-mark abscisses from the document corner \mthick=.2pt % thickness of the crop-mark abscisses \overlap=0mm % document borders can exceed to the crop area by \overlap \hmiddle=1 % number of equidistant middle marks in left+right margins \vmiddle=1 % number of equidistant middle marks in top+bottom margins \docropmarks % reads \document.pdf and creates new PDF file --------------------------------- and run it by: pdftex crop or optex crop Of course, you can set different values than these default ones mentioned in the example. The information text defined in the \info macro can include \document.pdf (document name), \folio (page number), \today (current date). For example, you can try: \def\info{\tt [\document.pdf] -- \today\ -- page: \folio} You can run cropmarks without creating the crop file directly from command line: pdftex cropmarks '\def\document{name} \docropmarks' This command reads name.pdf and creates cropmarks.pdf as the output. You can have your own configuration of mentioned values in cropmaks.cfg file and run pdftex cropmaks '\input cropmarks.cfg \def\document{name} \docropmarks' You can use optex instead pdftex, of course. If you are printing at duplex printer then the pages at front and back sides must be ovelapping. It means that you must know the real sheet size used in the printer and the printed material is centered in it. If this case is true then you can declare \sheetsize (width,height)unit for example \sheetsize (800,600)mm or you can use predeclared types by \sheetsize sheet-type, where sheet-type is one of a0, a1, a2, a3, a4, a5, a0l, a1l, a2l, a3l, a4l, a5l, b0, b1, b2, b3, b4, b5, b0l, b1l, b2l, b3l, b4l, b5l, letter, letterl. When \sheetsize is declaed then PDF output dimensions are set to these values and the input pages including crop marks are put to the middle of sheet. The declared sheet must have greater or equal sizes to input page size enlarged by margins for crop marks, otherwise the \sheetsize declaration is ignored. Default: \sheetsize isn't declared, i.e. the PDF output dimensions are exacty calculated from input dimensions enlarged by margins for crop marks. If you want to put more pages to one sheet then you have to do this job first and then you can add cropmarks for whole sheets. Use another software (or your TeX macro or use OpTeX trick 0088) for creating sheets and create a new PDF document. Then set appropriate number of middle marks and read this new document with sheets at input side when you are using cropmarks.tex The middle marks are only single lines by default (intendend for paper bend only). Sometimes we need to leave a space for crop area here too. This is possible by \middlecrop vnum:{dimen} or \middlecrop hnum:{dimen} declaration. The "h" is declaration for \hmiddle marks (left+right margins) and "v" for \vmiddle marks (top+bottom margins). The "num" is order number of given middle mark and dimen is the amout of the space between crop marks created here (the single-line mark for paper bend is added between them to the center). For example, you can create "imposition sheets" with 8 pages per sheet shown in the example of the OpTeX trick 0088. See also https://en.wikipedia.org/wiki/Imposition. Then you can declare: \hmiddle=1 \middlecrop h1: {18mm} \vmiddle=3 \middlecrop v2: {14mm} It says that there is single \hmiddle mark which is intended for bend followed by crop 9mm and there is first and third \vmiddle mark intended for bend only and second \vmiddle mark is used for bend followed by crop 7mm. We get something like this: _| | |_|_| | |_ page page page page _ _ _| |_ _| |_ page page page page _ _ _ _ | | | | | | |
