Means that particular paper can't handle the ink load of those particular inks with those curves. Common problem with 
pigments, MIS more so than Piezo. Papers that have these problems require a lot of testing to find out at what percent each 
ink begins to mottle, and also what percentage of ink combinations begin to mottle, as well as total oink limit. oink.
Once you know this, your curves can be worked out within those limits. Generally you bring each ink in up to within it's limit, 
then back it out fairly quickly. Usually results in steeper curves that are harder to perfect, and using each darker ink a bit 
higher up the scale to get the proper value with less ink density.
With some papers like Arches that can't take much ionk, it may be  best to "curve" the lightest onk right out of the picture, 
and just do tritonkes.
Even better, don't use that paper...
