.quad file from QTR-linearization

.quad file from QTR-linearization

2016-12-12 by pianoquartet@...

I just tried dropping the .txt and .quad file onto QTR-Lineariza-Quad.exe. I got a ****-out.txt file, but no .quad file. There didn't seem to be any warnings. This is on a PC Win 7 Pro.

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.

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.

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.

Larry,

Can't say anything about the accuracy of data.

But as far as the linearize scripts they are not built for any particular device since they just
look at txt data files. So they do depend on the software that writes the data file.

The scripts look of data that is arranged in columnar form. They are quite flexible in the actual
format and attempt to decipher what ever is there. The -out.txt file usually shows what it
thought the data was.

I don't know the Munki data format you are looking at but if you'd send me the data that didn't
work I'll see what sense I can make of it. (btw, in general its always best to show what you
have rather than just saying it doesn't work)

Thanks,
Roy

Thanks Roy,

I was under the impression I was unable to include attachments in the Yahoo group.  An attachment would have been helpful, I agree.  At lot of my problems are a part of my own learning curve, however. 

The first hurdle I had to overcome was exporting the Munki data into a text format.  The Munki software exports to a .cxf file which must be imported into Excel.  There is a tool to do this called ColorMunhki_XmlImport that is very useful.  I believe the i1 can export a .txt file, or something more useful than Munki's .cxf file.  I think this is what I meant by your tools being designed for more for the i1.  Perhaps it's more accurate to say that most of the workflow described for linearizing .quad files is for the i1.  I've got it working much more smoothly today.  If you're still interested, I can send you the .cxf file I made when I measured in rows of 21.  I used the 4x21 random patches normally used for the i1, but spot measured each patch.

Because most of the workflow for linearizing .quad profiles is based on the i1 device, I've had to do a lot of trial and error to figure out the workflow with the Munki.  I think the biggest mistake I made was that I measured the 21x4 random patches in the rows of 21.  The resulting txt file that I imported did not give L values in the same order as your QTR-21x4-random.txt file.  I should have noticed that early on, but I'll admit I didn't really know what I was doing yet, so I was just trying to adapt the i1 workflow to the Munki.  

I have since rearranged the order of the patches in my own copy of the QTR-21x4-random.txt file to match the order in which I measure the patches.

I have discovered that the QTR-linearize_quad.exe will sometimes produce an -out.txt file with no error message, but no -lin.quad file.  When I said it didn't work, there was no error message to tell the group.  However, I have determined that most of my failures up to now were due to my ignorance.
