Does improved gloss Dmax ad to image quality.

2009-03-26 by Ernst Dinkla

It's an open question for me and I would like to see some comments on it.

Quotes from different threads:

The other is Piezography Glossy Selenium MPS system with GO and a new 
very high
dMax MPS black. This new black is a technological breakthrough as it 
uses a new
type of macro-molecular modification that is not normally applied to ink 
making.
The black without GO is typically about L*5. With GO at L*1.75 to L*1.5 
and I
have not yet bottomed it out in curve designing.

This is still in progress and the inks are designed around heated paper. 
But the
prints are very good. dMax is 2.45 or better on the 5 papers I am 
bringing. I
think with time I can get more dmax but I do not know if anyone can 
really tell
how black black gets visually after 2.50. The linearization on these 
prints is
very open. The shadow detail is extraordinary considering the dMax. I 
personally
have not see anything like this before. They look very much like silver 
prints
with a palladium linearization (straight line). The expectation of the 
silver
toe and shoulder are missing.

I plan to perfect the surface sheen and offer several GO options and 
this will
become the heart of the Piezography B&W Printing Labs. The next phase 
will be
split-tone Gloss.

The 1400
with HP PK on Crane Silver Rag hits a dmax of 2.72, not 1.72 as
written in the original post.  The 2.72 100% QTR patch has now
dropped to 2.61 after over a week of drying.  Needless to say, this
is outstanding.
