Here's a convenient test file to help choose a schema or write a new one:
(Note that background=screen is deprecated in MKIV and should be replaced by something like background=color,backgroundcolor=lightgray.)
<context source=yes>
For more information, see the article on [[Including pages from PDF documents]].
=== Custom imposition schema===
You can create a new imposition schema to meet your needs. To do so, take a look at the imposition definitions stored in <code>page-imp.mkiv</code> and find the closest one to work with. You can access the file online:
https://source.contextgarden.net/?search=%5C%5Cdef%5C%5Csetuparranging
Let's say we want this page arrangement on one sheet (R = page upside down):
<pre>P4 P1
R3 R2</pre>
This is a mirrored/reversed version of {{cmd|setuparranging}}<code>[1*4]</code>, which gives:
<pre>R1 R4
P2 P3</pre>
