Follow up,

On gloss printing with the Z3100:

On the Wasatch SoftRip 6.2, that I also have, the settings 
for adding GE are far more advanced than what the HP driver 
gives. You can select either full page or image only and 
both in three grades Light-Medium-Heavy and Off of course. 
That separate from the ink limitation + curve that's also 
accessible for that ink channel. There's very little GE 
needed to suppress bronzing.

On the other hand I still have to get/make good color 
profiles for that RIP as the existing ones are not at the HP 
driver level and there's no quad configuration with any of 
the matte papers like the HP driver has. The black channel 
partitioning is simply not accessible like it would be in a 
QTR style RIP.

I do not know what HP has in store on firmware upgrades but 
a bit more of the GE control would be nice. There's a new 
firmware upgrade since a few days but that mainly addresses 
paper transport and feeding issues and the driver that 
belongs to it isn't added right now.

On gloss and drying: as I understand it the analogue RC 
papers showed a much better gloss when dried with infrared 
dryers like Ilford 1250 etc than air dried or dried with 
non-infrared dryers. Even soaking papers again that were 
dried by other machines showed improved gloss with Ilford 
dryers. Has someone ever used that last method for RC inkjet 
paper ?  My guess is that much of the coating components of 
both types of paper are quite similar and could react the 
same way. The waterfastness of for example the HP ID Premium 
Gloss RC paper could be sufficient to keep the pigments from 
wandering in the image but the proof of the pudding is in 
the eating and I have no Ilford dryer.
