Digital BW, The Print

Don
It seems to me that you may have a long development time ahead of you to get
good results with VM inks. Good Luck. Make sure that you have a step wedge
as part of your neg and final print and use that to gauge your curve
adjustments

I never  got sufficient quality from the 1160 either with Epson or Piezo
inks and drivers to make good digital negs with Pictorico. Too much visible
banding and posterization.

BUT, if you can get hold of a good well setup Epson 1270 then with Dan's
workflow, Epson inks and Pictorico the results can be stunning. With
Platinum and other coated papers the process is a little more forgiving and
great results are fairly easily obtained. With glossy silver paper that will
cruelly show every artefact you will need a carefully controlled workflow
but the results can be totally indistinguishable from a projected print.
Strangely the 1270 works very well, but the 1280/1290 printers have a very
different ink laydown and are no good for me.

If you can get on one of Dan's workshops - do so - they are well worth it.
