BO using Eboni - loss of shadow detail

BO using Eboni - loss of shadow detail

2005-12-01 by fitness2health

My prints on a 1270 using Eboni Black Only have a loss of shadow detail 
compared to the MIS UTS-FN inkset using Paul Roark curves. I have also 
printed BO on a R200 and there is even more loss of detail.

Is there a way to control shadow detail when BO through 
brightness/contrast?

I it possible to control shadow detail printing black only with QTR, 
and if so what is the setup?

thanks in advance

I don't believe brightness/contrast would be helpful. You can,
however, use a Pshop or equivalent curve to do so. It involves bumping
up the curve in the lower values, printing a stepscale and adjusting
etc until you are satisfied in an iterative process, then saving the
curve to apply before printing. That is a crude but effective method.
Yes, QTR can be used as well. It will involve a greater learning
experience for you unless someone here can help you with an already
generated curve for your machine, ink and whatever paper you are
using. That would likely help but also not be optimal.
Search back a short time in this forum and you will find a procedure
by Paul Roark mentioned that allows making ICC profiles with QTR by
using a scanner. That is probably your best bet. It would allow for
using standard printing practices.

My experience with Eboni BO has been just the opposite.  I'm wondering
if it might be your image profile and printer gamma settings.  I've
written an article describing my BO workflow, you might compare it
with your settings.  It's article #3 at the link below.
