Digital BW, The Print

I had no idea you could do that with the tables either. Duh. The website is more sophisticated than us viewers.

Before we get too deep into the various drivers and rips of K3 printers, I want to see what happens to ALL the ink formulations of what he has already started and already has samples in house for when they reach the top limits of the conservation rating. 

But I am super curious about Cone Color as Walker is, because it is being sold much cheaper than Ultrachrome.

But -  my main curiosity is black and white because I think that has become the most mysterious, especially when it comes to the way Wilhelm and others have discussed it in the past.

In other words when an ink on a rag paper moves beyond 90% of this I metric upper exposure rating or 80% above the lower level measure, when the total megalux hour exposure is only say 40 megalux hours, then you need to think seriously about the system you are using.  Forty megalux is equal to a 20 year Wilhelm year rating, which is nothing really. So when we start to see bad things happening at 40megalux, 60 mexalux , and 80 megalux exposures it is time to be extremely concerned about monochrome color shift. And that is the thing we have fought over for the last 4 or 5 years on this forum with very little data to confirm our positions.

There are going to be all kinds of subtle variations between even the same inks and similar media, but what I'm looking for is -  larger patterns - patterns of similar failure of the same ink set or media provided by different members, in comparison to patterns of other ink and media tested under the same exact conditions. 

Once he sees the trends of all these systems side by side we are going to have a hell of a lot to talk about, more info than we ever had to evaluate black and white inkjet up until now.
