QTRGui 2.1.1 requires (PC) QTR 2.1????

QTRGui 2.1.1 requires (PC) QTR 2.1????

2004-12-01 by ferdinand_paris

On Stephen Billard's QTRGui site, the latest verion is 2.1.1, and
there is the following statement:

"QTRgui is a front end to Roy Harrington's QuadToneRIP for Windows
(harrington.com/QuadTonePC.html). This release of QTRgui is optimized
to run with QuadToneRIP version 2.1. It will support version
QuadToneRIP version 2.0; however, some options shown in the GUI may
not be available in this older QuadToneRIP version. It is strongly
suggested that you upgrade your QuadToneRIP version."

But the latest version of QTR for the PC is still 2.0 beta3.  Is
Stephen just a little ahead of the game, or am I missing something?

The easiest way to see the effect of these sliders is to make a few 
prints of the 21 step wedge from one of the QTR folders while moving 
the the sliders around a few times. In general the ink adjustment 
affects the first few steps of the wedge, darkening them when you 
plus the adjustment and lightening them when you minus it. I don't 
have a reflection densitometer but to me it looks like only the first 
two to eight or so steps are affected depending on the strength of 
the adjustment. The gamma adjustment is a little less clear to me. By 
referring to "midtones" it implies that only the midtones are 
affected but just from looking it seems to do what you would think 
any gamma adjustment would do, i.e. affect overall contrast in that 
both ends of the wedge are affected as well as the middle.
