QTR-Quadtone RIP

The targets in the EyeOne folder are just a tad too wide for my
Spectrophotometer to easily read white space at the spots marked
Beg(inning) and End.  So I loaded the ones I needed in Photoshop and
scaled them slightly on the horizontal dimension.  I was then able to
make my first profile.  But in the instructions there is reference to
Drop-Quad-Profile.  And there are all these Quad files.  Is it
necessary to make one of these in creating a profile?  The one I made
with the Curve Creation tool is a new Epson Matte 3K profile, since my
R800 apparently puts out too much ink. It seems to be linearized and
prints to my satisfaction. 
Now that I understand the process I look forward to profiling any
paper I use consistently with QTRip.  Thanks for the support of all
who have answered my newbie posts.
