I just wanted to clarify the claim of increased "optical resolution" with
the Piezo software.

What Piezo software does, among other things, is make for smoother
highlights by using a different dot pattern -- in effect, smaller and more
dots.  This is mostly noticeable with the 3000, but there is also a small
improvement with the 1160.

The Piezo software does not increase resolution of Epson printers in terms
of line pairs per millimeter.  See the resolution test comparing the Epson
driver with the Piezo driver on an 1160.  Go to the "Files" section of this
forum (URL below) and follow the links  to "Message Related Files," then
"10_2001 Uploads," and finally "Piezo-Epson Resolution testing."  The Files
section is at:
http://groups.yahoo.com/group/DigitalBlackandWhiteThePrint/files/

With the 1160 you can use the MIS FS or MIS FS-neutral inks if you have one
of the workflows for the Piezo/FS inks.  See, for example, Jeff Randall's
partitioned workflow for the 1160 & PC in the Files section.  Follow the
path "Inksets, reviews, and techniques," "MIS FS," and "1160 Partitioned
Workflow."

The 1160 also has workflows that control the MIS VM variable-mix/tone
inksets.

Note that you cannot use the Epson driver and FS or Piezo inks with the
1290.  So, the 1160 is more versatile as a quad printer.  Although with the
MIS VM inksets, some prefer the slightly smoother highlights of the hextone
printers.  (I use an 1160 and find it excellent with all of these inksets.)

(Others will have to comment on the ImagePrint RIP.)

ImagePrint 4 controls the printer and enables it to do 8 passes of the head. This in effect exceeds the resolution of the Cone driver. BTW, it is not "Optical Resolution" that you are getting but an effective increase in printer dpi. In reality the printer is still a 760 dpi printer, but the multiple passes effectively increase the dpi.

  Subject: [Digital BW] Imageprint 4 RIP and more


  hello!

  I have read about the ImagePrint 4 RIP, and also something 
  about the Cone Piezography RIP (for Epson desktop printers), 
  that works as a Photoshop plugin and increases the optical 
  resolution of an EPSON printer by replacing the EPSON software 
  in favor of the Piezography broad-band microweave.

  Does the Imageprint 4 RIP also increase the optical resolution, 
  or how is this rip compared to the Piezo RIP?
  Or what else should make it a better choice?

  Can I use the MIS FS and FS-Neutral inks with the standard 
  Epson driver, or is a rip needed for best result?

  What about the Epson printers. I have both 1160 and 1290, 
  which one will give the best BW prints with MIS FS/N inks?

  Thanks for any help,
  Bjorn
