exceptional about this printer (that even the Barcelona guy didn't realize) is that
the gloss opimizer (GO) can be printed on the image only, and not on the white
borders around an image. If you go into the driver's custom options for the GO
you can choose between "off", "Econo mode" and "Whole Page". Despite the fact
that their documentation inaccurately states that the Econo mode puts the GO
on the white areas of an image, it actually does the opposite. Econo mode puts
the GO on all areas *except* those with absolute paper white. So as long as
your image doesn't have any RGB=255 or CMYK=0 areas (which it shouldn't) the
gloss optimizer will print only on the image areas and not on the paper white
borders, simulating a spot varnish. Makes sense? I think this is significant for
prepress markets and they should be bragging about this feature. >>
I can't imagine what HP Barcelona engineer doesn't know about the Gloss
Enhancer (GE), but your description is basically correct. A couple of added points:
* There is a workaround to get the GE into the spectral highlights
(255/255/255) within the image, if you have any. Just select those areas (Color Range)
and fill with 254/254/254. This triggers the GE to blend into those areas,
although it won't be very strong.
* The GE is not a spot varnish but is blended with the other 11 inks. So when
using in Econo Mode on Gloss or Semi-Gloss it tends to look not much
different than the media. The trick is getting it to work on Matte, which it doesn't
normally do. But you can fool the printer in thinking it has Gloss paper loaded
to get around that. However, I know of a photographer who tried this and, if
I'm recalling right, he didn't see much of a gloss result. But a good thing to
experiment with. I'll have to try it.
