Problem solved. It was the GAMUT Mapping. Thank you to Refik and Alexey. This list continues to be an education and has saved what's left of my sanity once more. Kind regards Gerald On 14 Jul 2014, at 20:00, colorsync-users-request@lists.apple.com wrote:

Hi Gerald,
Please check the Gamut Mapping setting. It should read "LOGO Colorful". If for any reason GAMUT mapping has been set to either LOGO Classic or LOGO Chroma Plus, you will see such highlight limits. I do not really know why have these two legacy settings have been left in the software. The help file say LOGO Classic is there for PM3 Compatibility and LOGO Chroma Plus is for PM4 compatibility.

Hi
I'm a long term PM5 user and have been mostly happy (if occasionally frustrated) over several years. Recently my printer profiles have been giving me a grey flat tint across all highlights from about 220 RGB (about 15% grey). The rest of the range is very close to previous.
A couple of weeks ago I replaced a printhead in my z3100 and so am having to replace my profiles. For some papers (fine art matt) the internal Z3100 profiling is OK, however I need the extra shadow detail for photo papers. For years I ran Profilemaker on Macs, but finally OS upgrades made me switch PM5 to a PC last year. All fine for about a year. Main PC is XP (service pack 3). Not connected to internet so no auto upgrades or viruses. Have also tried on a separate Windows 7 machine with same results. I have also created profiles using old measurements that were OK but are now also giving the same problem. So it does not appear to be the i1Pro (I have also run the diagnostics & all seems fine). I've double checked & is not a v4 profile problem.
The only thing that seems to be a constant is the dongle (I have downloaded, un-installed and re-installed the HASP driver).
Any suggestions or help would be much appreciated.
I have started looking at Argyll as an alternative but need some time and a much clearer head to get into it properly.
Thanks in advance.
Gerald Dunne

Hello Gerald!

It seems you are using Logo Classic Gamut mapping. As I remember correctly, the latest PM5 had a bug with this Gamut mapping. Such problem was clearly visible even in ProfileEditor in Gamut view tool. To solve the problem you need to recalculate profile with Chroma Plus or ColorFull.

If memory serves me, the differences in Logo Classic, Chroma plus etc only occur with a perceptual rendering intent so it might be useful to run tests without that RI.
