Digital BW, The Print

Out of curiosity I printed the step wedges on Somerset Velvet and scanned
the results.

The two cool curves produced the same coolness as on EAM, but they have flat
spots at about 65-75%.

The medium warm curve gives a rather neutral print with a slight coolness in
the shadows.

The warm curve gives a maximum warmth at 30% that is about like the medium
warm curve on EAM (red about 6-7 more than blue).  In the shadows there is
some coolness, with a maximum coolness of 4 units (blue-red) at 90%.

Hello, Paul
I would be curious to know if you printed those step wedges on an 
1160? If so, I will do more tests with somerset on my VM/1160, and 
try to get a workflow established. 

I have a few other questions:
Was there considerable dot gain with your prints? Did you have other 
curves in there to pare back the ink flow on the uncoated paper? Did 
you try a test print of one of your images for comparison?

thanks for looking into uncoated papers,
ken

Ken,

No, the results I noted were printed on a 3000.  My 1160 now has a different
version of the variable-tone inkset in it.  I tried the SV with that, and
found it to print cooler than I would have expected given the results with
the 3000.  I don't know if it is due to the different pigment base or the
printer.

>Was there considerable dot gain with your prints?

I'm not sure how to measure dot gain.  I do think, maybe I can see some
bleeding along one edge, but I'm not sure -- it's not a big deal.  On the
other hand, a resolution chart printed on it is impressive.  The SV can
resolve the 7.2 lp/mm target that represents the highest resolution of a 360
dpi image file (alternating black and white, one-pixel-wide lines).

No.

Yes.  In my view they look flat -- low contrast with weak blacks.

Paul:
Your willingness to answer questions with this inkset, encourages me 
somehow to keep trying it with the uncoated papers that I like. That 
may seem strange, because your technical figures are not all that 
encouraging for somerset velvet. After all the work you've done to 
make the inkset available in the first place, I can sure keep 
experimenting with SV a bit longer!

I just printed some cards made of strathmore watercolor paper stock, 
using the VM inkset in my 1160, and they turned out really nice. So 
what the heck...

thanks,
ken

Ken, are you familiar with Cheap Joes Art Supply in New York? they have
about 3000 papers. I bet you can find one that will give you what you're
looking for!  Nice friendly service, too.
