I am using Spyder3Print 4.1.1 to create printing profiles and printing through PhotoShop CS4. I'm printing with an Epson 4800 with ConeColor inks.
With the new ink set, I set about to create a new profile for the inkset. I followed the instructions and printed out the 9 sheet of patches, allowing them to dry overnight. I read all the patches and created the profile, giving it a name, all within S3P, then hit save.
Going into PS, I picked an image to print(a test image from OutBackPhoto

and went into the print dialog.
I called up the new profile I made in S3P and made sure that color management was off in the print driver, letting PS handle the CM.
I made the print and let it dry.
I noticed that in needed some modifications and went back into S3P and called up the profile I made, clicked on Advance editing and moved the sliders to make corrections. I then clicked save and gave it a new name, after which it told me where it was on my HD.
I then went back into PS, brought up the same image, and pulled up the "new" profile and printed it out. I did this for 2 additional prints, each time going back into S3P, making modifications to the original profile that I made, giving it a new name, etc.
After examining them under the same light source, I could not see any difference from one print to the next, even though each was printed though a new profile. All on the same paper, all with the same rendering intent, PS handling CM, etc.
With the changes I made, I thought I would see differences and on the last one, I even went so far as to exaggerate the settings. All the prints look identical. I made chages to contrast, brightness, saturation and color, it didn't matter all the prints were identical.
Whats wrong?
