In Qimage Ultimate I can put two images on one print page (make sure 
both have enough space to fit on that print page), lay the last loaded 
on top of the other and give them different ICC printer profiles 
including QTR ones and print the total. That worked at least in Print to 
File mode but I do not see why it wouldn't in a normal print job. 
Practical issue may be that you need a larger print page to load the 
images but like to have a smaller one for the print.

For practice I would think it is easier to check with Print to File what 
a QTR RGB profile does to a certain color in Qimage and select a Qimage 
border color with the same RGB values.
