Re: [QuadtoneRIP] .quad file from QTR-linearization

2016-12-13 by Larry Beach

Just to be clear, all the evidence I see is that the data is accurate.  In fact, I'm able to use the i1 21x4 patches if I use the spot measurement.  I figure it's just that because most people who are interested in linearization .quad files probably have i1 devices, so the tools that Roy developed are designed for the i1.  

I'm sure that PPE will make using the Munki much easier.  However, I can confirm that it is feasible to use the Munki to linearize .quad files.

My Aurora Art Natural is so far from linearity (looks like one of those quadratic functions we had to plot in math class years ago) that QTR-Linearize-quad won't linearize it.  I may have Inkjetmall profile it, but that would be like having  someone add a supercharger to a Toyota Tercel.

       ColorMunki software (color-picker) exports some
 messed up data.  It’s not the quality of the sensor (they
 are basically the same between the two devices) but it’s a
 difference in data output from the software.
 PPE will be back on sale
 shortly.

 Finally got it.
 QTR-linearize seems to be
 optimized to read i1 data.  To use Munki data I had to
 borrow a .txt made by some one else's i1, then copy and
 paste my L, A, and B values in place of theirs.  Once this
 was done, I got a .quad file just fine, and linearity is
 improved greatly.
