Re: QTR for Windows with the Spyder3print (Was ink separation test page problem)

Ok. First, Thank you Joe for your reply. It kind of answers some questions, but raises some more.

Very true, but David Miller did post a "procedure" on the DataColor_group here in Yahoo, but it too, raised some questions for me.

I was aware of this so I still have 2.6.2 loaded.

Ok. Here is where I start to think I get it and then don't. Is this the part where you print out the ink Calibration page? If so then when I start to measure(with the S3P, I'm not really sure if I'm reading everything right. Maybe I am, but how can I tell?

 ...and it is time to print out the QTR 21step.tif  you will find that the steps are  too small to use with the Spyder3print device.

I brought the QTR 21 step wedge(found in the program file) into PS and it measures 2x7.675. That sould be plenty big to measure. But does it get printed out in PS or through QTR. If through QTR, then it could be brought into PS, saved as an untagged tiff and then called up, but I'm only guessing. I would imagine that the file needs to printed with no color management. In the print dialog in PS, setting the printer to color manage and the selecting "No Color Management" in the Epson dialog would do this would it not?



  Make a print of this in QTR using your curve....
What curve?

Ok. I have Excel, but have never used it and don't know how(or I'm not doing it correctly). I have Excel 2007. What is the data suppose to look like?

To me, there seems to be a lot of assumptions made. Kind of reminds me of the old Steve Martin routine of how not to pay taxes on a million dollars. First, get a million dollars......

Don't get me wrong. I really appreciate someone coming forward and handholding me through this. I really want to understand QTR, but I don't know if I'm asking the right questions and getting them answered or only making it more difficult than it should be. But please, let me know if I'm on the right track. I'm willing to take baby steps, but I'm itching to start running. Again thank you so very much.

As an aside. I am not using all Epson inks, nor am I using all shades of grey(i.e. Jon Cone's peizo inks or MIS inks) but rather a hybrid of Jon Cone's ConeColor and his Selenium shades for the LK & LLK, along with the Epson PK.
