Taking A3 pages and reducing them to A5 so they can be printed as a booklet of A4 sheets is simple enough.

Many thanks for your reply, Bruce. All I need to avoid here is to reduce any A3 image (there are calendars, such as https://texample.net/files/birthday-calendar.pdf).

But I don't understand what you mean by "cut each A3 page in half"?

With an A4 booklet, I mean the paper size when folded. The paper used to print an A4 booklet is A3 (folded in half). I need to cut the A3 landscape pages in half (two portrait A4 pages) in order to avoid reducing them. After having that, rearranging them in an A4 booklet is simple.

Is the A3 already in the form of two A4 sheets per page so that there is a gutter between them and you effectively want to extract each A4 half page, arrange in order, and then print reduced to A5 in a booklet of A4 sheets? As far as I get, no.

I mean, there should be no gutter (no extra space) and no reduction is needed. I hope it is clearer now what I’m aiming at. Many thanks for your help, Pablo

if you cut the A3 you'll get two A4; why not use A4 directly without a need for cutting?

Sorry, vm, I mean digitally separating the contents of a single landscape A3 in two portait A4. I have just found it with MuPDF: mutool poster -x 2 -y 1 input.pdf ouput.pdf I wonder whether there is such a feature in ConTeXt. Many thanks for your help, Pablo

Hi Bruce, now I see that nx and xy in \clip may achieve what I’m looking for. Many thanks for your help, Pablo
