QTR-Quadtone RIP

I have discovered that the soft proofing is different in 2.3.2 than it 
was in 2.3.0, as follows:

In 2.3.0, paper color can be selected but this does not automatically 
select ink color.  This is a very accurate soft proof.  It is not 
possible with any combination of soft proof settings to select ink 
color.

In 2.3.1, when paper color is selected, ink color is automatically 
selected.  There is no way to select paper color without ink color.

With Epson canned color profiles, soft proofing works as with 2.3.0.

The ink-color-checked soft proof does not provide an accurate soft 
proof of the print output with regard to darker tones.
