Digital BW, The Print

I have found that using Paul's ICC profiles for the r220 produce very pleasing results.  

Is there any way to alter the toning from neutral to cool or warm using this method?  I'm 
familiar with Clayton's method, but I'm specifically wondering if there's a way to achieve 
warm or cool tones using Paul's ICCs.

Thanks,
Chris

Today I've been trying a mixture of Paul and Clayton's method.  I'm using Paul's ICC profile, 
but then manipulating the slider to cool or warm the print.  It seems to work, but quite 
honestly I am very inexperienced with any kind of B&W printing, digital or otherwise, so I 
don't fully trust my eye yet.  Is there any reason this "hybrid" method I'm using wouldn't work 
well?

The intent of the "EZ" systems -- the C86/88 and R2 for 220 and others --
was to allow monotone ICCs, curves, or slider adjustments that would control
any arrangement of ink tones. 

There are 2 tones -- warm (pure carbon) and neutral-cool (depending on
paper).  The easy way to deal with this inkset is to simple put in different
combinations of warm and neutral carts.  

The densities of the dark shades of both neutral and warm are the same.
Likewise the warm and neutral LC, LM, and Y are all the same.

So, have 4 midtone bottles on hand:  Dark (C or M) Warm, Dark (C or M)
Neutral, Light (LC, LM or Y) Warm, and Light (LC, LM or Y) Neutral.

If MIS has spongeless carts, you can have fewer of them a simply flush
between tones.  

Try the same monotone ICCs, curves or slider settings for any combination of
the different tones.

I'm often find with cotton papers that a warm in the Y spot and the rest
neutral works well.

General information on the inkset and the settings I used are at

with specific driver settings at page 5.

ICCs were made with specific driver settings.  They work best if the driver
acts the same with respect to print density as when the ICC was made.  Some
settings may well be neutral in this respect, but others might change the
contrast or density distribution in a way that is different than the ICC
"assumes."  If the net density that the driver prints each input, then the
ICCs will work fine with other driver settings.

To make sure I understand: I need to keep the density the same for the ICCs to work well 
with other driver settings.  That means if I want a warmer print, I can decrease C by 10... 
but then I must increase M by 10 in order to preserve the net density.  If I do not balance 
the sliders like this, I will be changing the ramp which would alter the density distribution 
and may not play well with the curve.  

Have I got it?

BTW, I currently have a variable tone R2 inkset installed as suggested in Clayton's article.  
I'm not sure if this makes a difference to what you've just recommended.

Thanks for your reply, Paul.

That should work.  Let us know how it goes.
