I would like to have a template for reformatting some arbitrary LaTeX document in a way, that I can print and cut it, to glue it into my lab-book. To this end, the output should

• introduce a binding-offset,




• show crop margins for the binding-offset, as here the paper will be cut,




• and ideally the text width is not altered, but only moved (so the format is conserved).

While the first point is easily achievable with the bindingoffset=2cm option in the geometry package, the other two points are harder to realize:

While geometryshowframe prints all frames, I did not find a way to restrict it to the binding-offset margin only.

Furthermore I would like to counter the change of textwidth when a binding-offset is introduced, regardless of the documentclass used.

documentclass[10pt]article

usepackagegeometry
 geometrytwoside
 % use 20mm narrower paper than A4
 geometrypaperheight=297mm,paperwidth=190mm
 % still use the A4 layout
 geometrylayout=a4paper

usepackage[cam,a4]crop
 % print crop marks on odd pages (as printout is duplex)
 crop[cross,odd]

usepackage[utf8]inputenc

begindocument
blablub
enddocument

However, this leaves me with the layout on the left and white space on the right - the opposite of a binding-offset. The only option crop gives is center. So how can I align the layout on the right?

Of course I could go for the following example, but that rather feels like cheating...

documentclass[10pt]article

usepackagegeometry
 geometrytwoside
 % use 40mm narrower paper than A4, cheating
 geometrypaperheight=297mm,paperwidth=**170mm**
 % still use the A4 layout
 geometrylayout=a4paper

usepackage[cam,a4,**center**]crop
 % print crop marks on odd pages (as printout is duplex)
 crop[odd]

usepackage[utf8]inputenc

begindocument
blablub
enddocument

documentclass[a4paper]article
usepackage[noaxes,pdflatex,mount2]crop

REMOVE the following line for a real document! Here pagecolor is just used to mark the page dimensions. crop normally paints the page background a little bit over the edges of the page, which makes sense when cropping, but I just wanted to mark the (exact) page dimensions.

setlengthmybindingoffset20mm

This moves the page content
mybindingoffset (here: 20mm) to the right on the first (right) page,
then mybindingoffset to the left on the next (left) page and so on.

For positive mybindingoffset (i.e. right side), a rule with thickness mybindingrule and height paperheight is placed left (hspace*-mybindingrule) of the page (and by rlap we pretend that it is not there anyway):

ifdimmybindingoffset>0ptrelax%
 rlaphspace*-mybindingrulecolorblackrulemybindingrulepaperheight%

For left sides the rule is placed right of the page:

usepackagelipsum
begindocument

lipsum[1-57]
enddocument

Note that the page layout is not changed at all, but you are losing mybindingoffset (here: 20mm) at the right of right and at the left of left pages, because it is move outside of the page, so to speak. If that is "whitespace" anyway, it might be acceptable.
