Haven't printed for over a year and thinking about replacing my aged Epson 2200. I hadn't realized Epson is selling a dye printer but with negative b/w results. Didn't see it on QuadTone's printer list and would appreciate knowing group;s opinions on the printer.
Thanks,
Arnold

Working on some base curves for the DYE and for possible forthcoming Piezo on this with a test driver. But it’s been put on hold for awhile due to a lot of other pressing needs . . . ink coverage is double due to doubled nozzles (Roy can explain the details). I’ve been waiting on him to limit the total dot coverage by 50% but in the interim have had no time just to do this in the curve(s) I’m making. Tldr: On the horizon. May take some time. It’s a really really nice printer (and cheap!). -Walker > On Jun 12, 2019, at 8:20 PM, arnnadf@...

This 1.5-6 jump actually caused weird reversals in 3/4 tones for me and ended up throwing me such a curve-ball for linearization that I scrapped it until I could get some solid time into it (where did that go I have no idea). I ended up re-building Gutenprint around it, limiting to only smallest dot size and this worked . . . -Walker [Non-text portions of this message have been removed]

I've got an Epson XP15000 printer that I've been able to test with. Its a bit
different than previous printers so its not exactly the latest reincarnation ofany previous model. While similar to 1430 in some respects - 6-ink Claria.It uses different inks -- the usual CMYK but then instead of LC and LM it hasGray (LK) and Red(R). Seems like this ought to make smoother B&;Ws sinceit has the LK but then toning will be done with darker color inks. The blacksare quite cold toned rather than warm toned like the UltraChrome inks.Anyway, I have a version of QTR driver that works with this printer, but since Epsonhas changed their communication protocols, there's more of a trial & errorguess method to making it work. All is mostly just fine but strangely the dotsizes from the inkjets are unusual. It has the advertised 1.5pl drop but thenext larger drop is much larger (about 6pl) rather than about 2.5 to 3.5pl thatother printers have. This makes it possible to output much larger amountsof ink. All printers have different sizes but this seems to be an outlier.But QTR driver has always had INK LIMIT controls so this is easy to fine tune in curvefor any printer. (the .quad files have ink values that just need to be smaller).This has nothing to do with number of jets.I guess there's one potential issue here -- the 1.5 to 6pl jump might be a littlemore likely to be visible. I don't believe this is a problem but who knows in rare cases.Roy

Will retest once I have slightly less stacked plate. Thanks! -Walker > On Jun 13, 2019, at 5:53 PM, roy@...
