I just did a back-to-back test with the new Pictorico vs the last sheet of old stock that I had. The new material has pretty blatant artifacts straight off the printer- obvious head-banding. It does smooth out almost completely on drying, but it's hard to believe looking at it fresh that it could ever really smooth out enough. Has anyone else noticed this with the newer Pictorico? I contact printed some some of my old kallitype-curved negatives as carbon transfers and didn't see any headbanding at all- so I'm starting to think that maybe the problem is with the new Pictorico..? I've sent an email to Mitubishi. On their website they mention using a HP Premium glossy profile that just doesn't exist on my HP printer; just HP Advanced glossy, which was the recommended profile for the old stock. And they don't seem to have any ICC downloads for the Pictorico line.
edit-I just tried using the plain HP premium profile. It does indeed print without the wet ink lines, but it looks much grainier and the doesnt seem to be enough ink in the high values. Looks promising though, and certainly worth experimenting with.
