Thank-you Max - that is exactly what I wanted and your code worked first time.

I don't think that there's any way to do this from within a document
run, so I think that you'll need to use an external program.
> If not, is there a recommended external program that can do it?
But, you can use ConTeXt as the external program here.
Save as "imposition.cld":
local filename = document.getargument("filename")
local pdf = lpdf.epdf.image.open(filename)
local pages = pdf.nofpages
local max = math.ceil(pages / 4)
context.setuppapersize({ "A5" }, { "A3" })
context.setuppaper { nx = 2, ny = 2 }
context.setuparranging { "XY" }
local function insert_page(n)
context.startpagemakeup()
context.filterpages({ filename }, { n })
context.stoppagemakeup()
end
context.starttext()
for i = 1, max do
if i % 2 == 1 then
insert_page(i + 0 * max)
insert_page(i + 1 * max)
insert_page(i + 2 * max)
insert_page(i + 3 * max)
else
insert_page(i + 1 * max)
insert_page(i + 0 * max)
insert_page(i + 3 * max)
insert_page(i + 2 * max)
end
end
context.stoptext()
Then run:
context imposition.cld --filename=document.pdf
where "document.pdf" is replaced by your document name.
I'm not sure if I got your desired output quite right here, but
hopefully you can easily modify the script if something isn't quite
right.
Thanks,

[NTG-context] \setuparranging values for perfect bound A5 on A3?
I have a book to be perfect bound[1] and I'm trying to work out what imposition to use. The printer would like 4 A5 pages laid out on A3 e.g. +---+---+ | | | | a | b | | | | +---+---+ | | | | c | d | | | | +---+---+ so that he can cut the paper and simply stack a, b, c, & d on top of each other and then put them in the binding machine[2]. If the book is 40 pages long, say, then stack 'a' has page 1 on the top, page 2 on the reverse, then the next sheet has page 3 and 4, and so on down to the last sheet which has page 9 on the front and page 10 on the back. Stack 'b' would have page 11 on the front, 12 on the back and so on, so that each stack has a quarter of the book. Is this something LMTX can do and if so what combination of \setuplayout and \setuppaper do I need to use? If they can be printed in reverse order then great but I assume the printer can do that fairly easily. If not, is there a recommended external program that can do it? I've tried \setuplayout[4*2] and XY with 2x2 but neither output is what I need. Thanks in advance. [1] glued spine (if that term isn't used outside the UK) [2] I'm sure it's actually harder than that. :-) — Bruce Horrocks Hampshire, UK ___ If your question is of interest to others as well, please add an entry to the Wiki! maillist : ntg-context@ntg.nl / https://www.ntg.nl/mailman/listinfo/ntg-context webpage : https://www.pragma-ade.nl / http://context.aanhet.net archive : https://bitbucket.org/phg/context-mirror/commits/ wiki : https://contextgarden.net ___
