Hi Hraban,
slightly modifying your MWE, I think I get what might fit your needs
(see below).
I never used \flushlayer and your sample shows that it doesn’t fit here.
The layer is relative to the page, not to the paper in this case.
And the state is an option for the layer (in \definelayer), not for the
background, being "start" its default value.
Just in case it might help,
Pablo

Re: [NTG-context] placing (on) layers
Hi Willi,
thank you, I wasn’t aware that \flushlayer works this way. This was also
the problem in my real project.
And I had the wrong layer mentioned in \setupbackgrounds from another test.
Also, cropoffset was interfering in the real project, see my other mail.

Hi Hraban,
if you flush a layer like in your example, then the layer is attached to the
left top of the text area. If you want to place it in another place, you will
have to move it by x and y dimensions to the right place in the first brackets
of the \setlayerframed command . — What would be possible is to attach the
layer as a background to one of the different areas of the paper.
I hope this gives you a hint how to proceed..

[NTG-context] placing (on) layers
Hi again,
I’m always struggling with putting stuff on layers, since these just
never start where I’d expect them to, and the offsets changed a few
times within the last years.
Please explain how I should define a layer that covers the whole page,
since the following MWE is wrong (the layer always starts below the
first line):
\useMPlibrary[dum]
\setuppapersize[A5][A4]
\setuplayout[
marking=on,
location=middle,
]
\definemeasure[Bleed][3mm]
\definemeasure[MaxHeight][{\dimexpr\paperheight + 2\measure{Bleed}\relax}]
\definemeasure[MaxWidth][{\dimexpr\paperwidth + 2\measure{Bleed}\relax}]
\definelayer[papier][
preset=lefttop,
%x=0mm,y=0mm,
width=\paperwidth,
height=\paperheight,
]
\setupbackgrounds[paper][background=cover,state=start]
\starttext
\showframe
TEST
\setlayerframed[papier][
preset=lefttop,
%x=-\measure{Bleed},
%y=-\measure{Bleed},
offset=overlay,
%frame=off,
width=\measure{MaxWidth},
height=\measure{MaxHeight},
]{\externalfigure[dummy][
width=\measure{MaxWidth},height=\measure{MaxHeight}
]}
\flushlayer[papier]
\stoptext
