I got a used Canon iPF 6400, changed a head and calibrated it. I also got a i1 Pro (first model) for creating papers profiles. I dont have much experience using it but it gaves good profiles for a few papers on my 3880. However for the 6400 I get strange gamut shapes with "holes" in it. The pictutes of it, given by the i1Profiler software are attached below.
The paper is Moab Entrada Natural. The software is i1Profiler 3.1.1 (it is the highest release number that support i1 Pro 1). 2200 patches were used and other setting are set to default.
What are these holes the symptom of ? Reading errors ? Printer failure ? Calibration device failure ? I find these holes very sharp for being due to the printer.
I am stuck and any explanation or suggestion is welcome.
Thanks
