Digital BW, The Print

I've gone through all the Z3100 posts and found little actually 
describing the appearance of the GE.  How would you describe the 
appearance in terms of color and gloss level?  Has anyone used this 
with the Harman Gloss FB AI?  Used over the entire surface, does the GE 
raise or lower the gloss as compared to the straight Harman paper in 
unprinted areas?  Compared to other of the gloss papers?  Does it raise 
or lower the gloss of the inks?  Is this a high gloss surface, a satin, 
etc.?

I know this can be a subjective call, but comments would be welcome.

Many thanks,
Walt
