hi Steve,

Yes, metamerism, cross-over etc etc are bigger issues the nearer you get to
neutral grey. e.g. a colour image with a magenta cast will not be noticed by
everyone... but 'most' people will notice it is your image is predominantly
'grey'. So cross-over (where one area of a greyscale is e.g. magenta,
another areas eg green) and metamerism are more of an issue. I have now sent
you some samples, but to be honest... they are not representative of what I
have achieved in the past... with a pro profile. Unfortunately, the pro
profile lost it's avalidity when I was forced to swap printers (and
actually, I moved from cart to a new CIS ink supply aswell) so just about
everything changed that shouldn't for such a profile to work.

RIP = Raster Image Processor. Yes, it would replace, or on occasion, be in
addition to the Epson driver. There is a fine-line here. In my view, even
the Piezo plugin (and in fact, the Epson printer driver) are RIPs because
they process raster images (bitmap images) - but it is usually associated
with higher-end products. I'm afraid I currently know little about (colour)
RIPs, but the implication here is that they give you more control over the
way ink is laid down by a printer. e.g. Epson printer driver does NOT allow
you to control CMYK inks individually, but I believe a colour RIP 'should'.
For RIP, read '???' (which probably won't come out on this email so read
'$$$' instead)

Referring back to point 1 - I hope you understand why I was not able to
spend too much time improving the greyscale print samples!

Best regards,
nij
