 (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:
