Thanks!
I've not had any problems with clogging but then again I've only put a few of the new 
cartidges through the 1290... and I do have that 9600 sitting in the room next door :-)

I think it was quite important to run the cleaning cartridges before the changeover since 
Ink pH mismatches are great for causing sediment build up and clogs. The PJ inks are also 
available for the 2100 where I suspect that as it was designed for pigments from the start, 
there would be less likelihood of clogs. Maybe running the cleaning carts every so many 
cartridge changes might keep the system 'fresh'?

There are no curves published by PJ for the 2100, but if the performance is like the 
examples I tried for the 2100 it might be best going for QTR from the start.

The QTR tests were certainly interesting and produced very good results. I should imagine 
that only a minority of people using the software would have an Eye One sitting around, so 
curve generation and linearisation would probably not be an easy option for most ;-(

bye for now
