Not until I  fill another inkcart set and put it in there. The 
bottle/vacuum filled carts were supposed to last through July and part 
of August, with a CFS being installed then, but with all the stuff 
going on a lot got wasted already.

Possibly, but I should also tell you that the PS7/Adobe98 print was 
run right before (first a nozzle check and then) the PS6/Adobe98 
print. Any misalignment would have shown up in the PS6 print as well, 
coming later.

Well it looks just a bit finer and sharper then the cordury that is 
slightly visible in all the prints. And it is above the threshold of 
"the wife test".

But, beyond that yes, the PS6/Adobe98 and PS7/Adobe98 are about 
identical, which is not the case for when srgb is used. Ignoring the 
microbanding fluke, the PS6/srgb print is still ever so slightly 
superior as the PS6 or PS7 with Adobe98 has a very very small spot of 
posterization. It is not enough to make me in the future NOT use 
Adobe98 for conversions. But the microbanding is now a puzzling issue.

What I'm really trying to say is I have the least problem when I use 
PS6, whatever the space. Also that the Adobe98 space does cause no 
discernable difference in PS6 vs PS7, microbanding ignored.

As mentioned, why didn't it show up on the PS6/Adobe98 print done 
after the PS7/Adobe98 print?

Alignment checks on the 1280 are in two parts: one for black ink that 
most people would recognise similar to say that on an 1160, and a 
second one for color which is pretty hard to do unless one loads Epson 
carts back in. However, I am told this second part doesn't make as big 
a diff. I haven't done one in awhile, but still question why it then 
wouldn't have shown up in the later PS6/Adobe98 print.

If I don't use up too much ink otherwise in the next week I will try 
to run an alignment and another print.
