You also need a popper as in: \installpagearrangement 2*8 {\dosetuparrangement{4}{2}{8}{5}{3}% \pusharrangedpageSIXTEEN\poparrangedpagesAB\relax} how/what depends on the scheme ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | voip: 087 875 68 74 | www.pragma-ade.com | www.pragma-pod.nl -----------------------------------------------------------------

Hi Marco, If I understand correctly what you need is a system which is basically based on booklet-printing but each booklet should be restricted to 16 pages. In this case you might try \setuparranging[2*2*4] This scheme put two pages on the front and two pages on the backside of a sheet of paper. Then it uses 4 sheets to complete the section.

Hello there.

I'd need a custom imposition schema, just like the 2*4*2, but first the sheets will be folded, then inserted in signatures of 16 pages, and then finally bound. (They said the machine can fold only one sheet).

I came up with 3 "solutions" (or 3 hacks, as you wish):

1. psutils/pstops

2. layers

3. hack page-imp.mkiv

1. The first solution would be the faster, but after spending a day on it I gave up, because I have endless issue with cropped pages, paper dimension not correctly set, and I only scratched the surface. I don't know if exists some support for psutils (doesn't look so), but I have the feeling that software is pretty dead.

2. Layers: I'm attaching the code below. Does it seem sensible, or is there a better way to do it? (I'll create a template from that, and will loop over every 16 pages with the usual perl hack). It seems to work, even if visually it looks a bit shifted to right (I can adjust it manually). [An alternate approach could be just various \hbox, but maybe the layer solution is better for absolute positioning]

3. page-imp.mkiv would be the best solution (obviously). I've dug a bit into the code, but I'm in deep waters. I can't understand where the sequence of the pages is defined. the \pusharrangedpageSCHEMA seems just to define the position inside the page, not the sequence of the shipped out page. Also, what are \c_page_marks_nx and \c_page_marks_ny? Any hint about how this machinery works?

Thanks

Best wishes
