Digital BW, The Print

I'd be interested in how you get on.

As for how much, it should be quite noticeable when the ink changes.   
The suggestion to print a series of known sized squares is a good one.

"The amount of ink required to purge the old black depends on your  
printer.
The SP7880 uses about 10-12ml of ink before the tube is flushed out.

Printing a solid black image of 17"x30" should suffice.

For Mk -> Pk: When you look at the finished print you see that it  
starts with matte ink as it looks dark and the rest of the print looks  
a little dull with Pk ink on matt paper. The system is now charged  
with photo black."



"On our 9600 we printed four 40"x10" solid black rectangles on cheap  
matt paper to purge the black line. The first 3 were a dark black and  
the third much lighter as the Photo black ink was used."
