QTR-Quadtone RIP

I hear you Michael... if it was that easy we would all be Ansel Adams's...

I have been churning away here, making prints that is, and by the time I run out of ink - which from the looks of it will be a long time - I may yet be up to were I would like to be with these carbon inks.

Thanks for the input... if I find any magik bullets I will let you know !

The bias toward Moab is mostly my own. It partly comes from the fact 
that the pre-punched and scored pages for my portfolios are Moab 
Entrada.

Others here are quite happy with many other papers. Certainly worth 
looking at the Moab, but I don't think it is any sort of "amazing 
fix" for the contrast or anything. ;>) Mostly just personal 
preference.

Jon Cone detailed the d-Max for some papers in a thread on the 
piezography3000 board recently:

Others by the color the paper imparts....
I would order as many of the paper sample sets we sell and choose that
way!

*******************************************************

You can see that the difference in dMax is not large among the group, 
though some are higher than others. Many of the "bright white" papers 
have OBA's (brighteners), which may make more of a psychological 
difference. The Entrada dMax is not much different than the Enhanced 
Matte in fact.



For comparison, I came across these numbers from Eric Chan's Epson 
3800 web site the other day.  Note the reference to dye based inks 
too ;>):

What is the deepest black I can expect with Photo Black (PK) papers?

In Color mode, I have measured L* = 4.0 (d-max = 2.35) on Ilford 
Smooth Pearl. In ABW mode, I have measured L* = 2.9 (d-max = 2.49) on 
the same paper. This is getting close to the performance of dye-based 
inks -- impressive! It may be possible to get deeper blacks on other 
papers or with different driver settings. 

What is the deepest black I can expect with Matte Black (MK) papers?

In Color mode, I have measured L* = 16.0 (d-max = 1.68) on Epson 
Velvet Fine Art paper. In ABW mode, I have measured L* = 13.8 (d-max 
= 1.77) on the same paper. It may be possible to get deeper blacks on 
other papers or with different driver settings. 

**********************************************************

Note that the "L* = 16.0" is close to the L=15 that I remembered for 
Epson Enhanced Matte when I did my QTR curves with Carbon 6.

Good luck!  Have fun without getting too much of a headache.

Best,
Michael
