Digital BW, The Print

Brian,
    That would be something I would like to use, if you find out how please let us know.
TIA.

That feature is in the US driver. It also only applies glosser on 
glossy or gloss-based papers like premium luster, based on your 
selection of paper type. Because the glosser is shinier than even 
Primium Gloss paper, selectively glossing inmages high lights them in 
what I consider a very attractive manner. I am sure that effect will 
be a matter of personal taste.

Personally, I'd like to see the ability to control the glosser like a 
separate color so I could selectively gloss different areas of the 
print. That technique is very popular in the graphics design world 
where the most extreme form of it would be to print the whole page a 
single color and then apply the gloss for the type and graphics. It 
wuould be especially effective over an ink with strong reflective 
characteristics.

BTW, I don't know it is not possible to control the glosser 
separately, I simply haven't had time to pursue it on the one R800 I 
have access to.

Taking a look at the programming manual from the epsondevelopers.com web site, it looks as if the gloss is controlled the same as any other ink at the driver level.  This means it is technically feasible to control the gloss independantly.  

I don't know if the Epson driver will allow you to do this (I doubt it).  I suspect you'll see it first in third party drivers and RIPs.  It should be fairly straightforward for gimp-print and (consequently) Roy Harrington's QuadToneRIP to support it.

I don't know how you'd control it though.  Maybe send two files through the driver/RIP?  the normal RGB or Grayscale file and a second "Gloss Mask" file?

It could be done with an alpha channel. Postscript as the file 
format is also an option. There are RIPs that already get an 
extra vector line image in the Postscript file to cut out the 
sticker circumferences in vinyl. Roland inkjets for example. Some 
RIPs can use spot color inks in one of the carts (Mimaki inkjets 
mostly), the color is selected then.
