On Behalf Of John Hill > Does anybody have experience of the Piezography system of BW printing on > Epson printers? Hi John,
Yes - I'm not sure my experience counts as I sell the stuff; but I do like the system a lot. You need a very good printer though. The Piezographjy driver typically lays down only two inks at a time, sometimes just one; where the Epson driver may be laying three inks down. The former can reveal problems in the printhead accuracy (positioning etc) where the latter is more forgiving. > I would especially like to know what you think of the different inksets > (Museum Black, Portfolio Black, PiezoTone grey sets, etc). Which > do you use and why? As you will hopefully be aware, the inks are now split into 'Blacks' and 'greys' or Tones: Right now, there are a choice of two Tones (Selenium and Warm-Neutral) with Cool-Neutral and Carbon Sepia to follow. To clarify, these are the 'Colour Position' inks CMY or CcMmY in carts or bottles. Our information is that the ink colourant is 100% pigment for the Tones. Apparently, stability of these greys is extremely good. The Blacks are literally that, a choice of Black inks that define dMax through their makeup. PiezoTone 'Black Black' (don't ask me why!) which is the 'original' PiezoTone Black formula. This is Carbon pigment base with some added 'fadeable' dyestuff. Longevity is still expected to be good, but because the Greys are very stable, any shift in the black may be more noticeable. This brought about: Museum Black, with a 100% pigment Carbon base with some new technology apparently to bring the dMax higher, just with pigment. Portfolio Black (if I have understood correctly) is the same technology Carbon base, but again with added 'stuff' that will fade in due course but it apparently kicks up the dMax. We have yet to see these new blacks so I am not sure many people will have done (in the UK anyway). I should stress that where I say 'fadeable' in the paras above, I mean, 'one would expect this to fade quicker than the pigment that it is mixed with'... everything will fade in time. I hope this helps. nij Nigel Rheam MWORDS Limited www.mwords.co.uk Digital Fine Art =============================================================== GO TO http://www.prodig.org for ~ GUIDELINES ~ un/SUBSCRIBING ~ ITEMS for SALE
