Digital BW, The Print

Adrian,

That is very strange as a densitometric comparison that I did of the same file in IP4 and Piezo indicated that the IP4 blacks were siginificantly more dense. Something approaching 2.0 as compared to 1.69. Maybe I will repeat the tests this weekend.

  I agree. I've got a demo copy of Imageprint on which Piezo is based. I don't know whether Jon Cone will have enhanced this for Piezo2 but there is certainly, IMHO, no quantum leap in quality with the base product. Printing the Proof of Piezography test image does show a smooth tonal ramp but then so does Piezo. The dither pattern looks as good as each other. Surprisingly the 100% black on EAM using Piezo measures 1.63 on my densitometer compared to 1.58 on ImagePrint. There is increased separation on the blacks with ImagePrint thereafter with 90% reading 1.40 on Piezo and 1.32 on ImagePrint. I always seem to be in a bit of a minority as I like the existing shadow separation in Piezo and never felt that it needed expanding.

  Strangely the Imageprint vertical resolution test lines show a strange horizontal banding but otherwise are comparable.

  Of course the ImagePrint evaluation software prints DEMO all over the image so it is difficult to make a comparision on an actual image. There doesn't seem to be an EAM profile so both were printed with the Cone Matte profile.

  If you want a copy of the print let me know

    Julian,

    My last message got lost in cyberspace...This duplicates it...

    Nij of Mwords kindly showed me a print made on a 7000 using the new 
    Piezo2 RIP this morning, and let's just say that so far as I am 
    concerned, the jury is out at the moment on whether Piezo2 print 
    quality matches Pro24 / PiezoB&W.  This is (if you'll excuse the pun) 
    still a grey area...

    Print quality is what ultimately matters most to me, and I would want 
    to see more examples before moving to the new RIP.

    As to more general comparisons with Imageprint 4, it is pretty 
    obvious looking at the interface that Piezo2 is based on Imageprint 
    4.  For more general info, all you can do at the moment is check out 
    the Piezo2 details at  
    http://www.piezography.com/piezography2.html
    and the pages linked from there, or you could try emailing Jon (good 
    luck!)
