Printing sheet size of an imposition in job name

[T_Winkler]

For optimizing our production of press sheet sizes, we would like to write the size of an imposed sheet into the file name of the saving node. 
We tried the following marks in FreeFlow 5.4.5: 

$FFwfDoc.pdfMediaWidth$
$FFwfDoc.pdfMediaHeight$

and

$FFwfJob.mediaWidth$
$FFwfJob.mediaHeight$

But even if I set the page boxes to the media size of the press sheet, the printed values are from the imposed PDF file. Are there other variables existing to get rid of the information?

I believe these are the variables you are looking for:

$FFwfDoc.documentWidth$

$FFwfDoc.documentHeight$

[T_Winkler]

The variables work perfect for the save node, where I can print to file. 
So thank you very much for them.

But they does not work in the MAX setting, where I choose the file name from the fields of the MAX file.

One could add a custom text variable(s) to the MAX setup. Then use the variable(s) and the Save node to rename the filename.
