Hi Onslow - whoever mentioned to scramble the patches (an option in i1Profiler) I agree you should do this. I recommend you use the XRite 2033 patch set, scrambled patches, and do a reprint of the profiling target using ACPU with the correct Media Type for the paper you are printing. Let it dry for several hours. Then re-read the target - if you are using an i1Pro2, use it in dual scan mode so you can profile for M0, M1 and M2. In case you aren't aware, right after scanning the target pages, first make sure to do a Save Workflow so if i1Profiler crashes (which it can) you don't need to start everything from scratch. Then make the first profile with the default M0, then go back to the Measurement Tab, select M1 as the measurement mode, and then skip over to the Profile tab and create a new profile in that mode with a slightly different name. Repeat for M2. Then examine the profiles in CTP to see whether the surfaces and contours are smooth - no dents or jaggies. If so, make test prints with each one of the three profiles and see whether one is just right for that printer/paper combination.
