Digital BW, The Print

Background...

1280 with MIS Perpetual inks (have a 1270 with MIS VMs too) both on CIS systems.
The 1280 has been profiled and been working splendidly.

Lately noticed a small color shift.  Nozzle checks were ok.  
Did a Windex under the print head briefly, currently doing a longer duration.
Re-iterate, nozzle checks are ok, even under a loupe.

Before ordering another profile, thought I would do a test print with a color cone.
In the color cone, in the red spectrum there is some mottling.  Not size specific.  Is repeatable on any scale.

Ideas?
