It is a little hard to follow your issues so I need to summarize and figure out what we are doing for you at this point.
1) Initially you asked for help in operating QTR on Windows to get better "sharpness".
2) Then you tried printing a QImage prepared Print to File through QTR to improve sharpening which it did not when you believe it should have.
3) Then you questioned whether you had a bad batch of paper.
4) We were going to look at your prints because of a sharpness issue related to paper. And you sent these which we just received.
5) Then you reported you had ink puddling on baryta paper and that your matte papers were soft and blurry.
6) You sent a photograph of an image on your computer screen and the resulting print of the image to Wells. It suggests that what is white (RGB 255,255,255) is printing as a light gray -perhaps as dense as 20% judging by the photograph.
7) You then reported that the GO had drained or run out of your printer prematurely, printing only 12 prints where 70 were expected.
8) Then you reported having to modify K7 curves to reduce ink load.
Between the ink puddling and the draining of an 80ml load of GO on 12 prints - I am thinking at this time that your issues are not related to paper or sharpness but rather a technical issue with your printer. I believe that the GO is being printed when it should not and that the curves being used are incorrect for K7 or are corrupted. The printing of GO during the printing of inks is ordinarily impossible with K7 curves and it would account for the softening and blurring of the image if it is printing especially in the quantity you are indicating.
Why this is happening could be the result of any of:
a) putting the inks in the wrong positions.
b) using Curves that were not produced by Piezography specifically for your printer model/family.
c) selecting more than one curve in QTR or using the adjustment sliders.
d) using Curves that have been modified.
e) corrupt QTR software or Piezography produced K7 curves could be triggering LLK head to print GO continuously.
f) using a QTR driver for a different printer model with your printer model.
g) mechanical failure of the print head.
h) some operation of QTR that is not recommended by the Piezography manual.
We can verify:
a) by your printing an sending a picture or scan of a Calibration Mode printing of inkseperation image. QTR prints that image automatically in Windows.
b) you have sent us the names of the K7 curves you are using. Please verify that you are using these in Curve 1 pull down prior to printing?
c) are you selecting more than one Curve when you print?
d) have you made any modification to these curves including Saving them even without your believing you have made a modification?
e) Always try a reinstall when in doubt!
f) Please verify your printer model and the name of the QTR pull down selection. (screen shot would be good)
g) possible that the LLK head has failed electronically and is just jetting fluid non-stop.
h) screen captures of your workflow from the Save As from Photoshop all the way through to the print button on QTR.
