QTR-Quadtone RIP

The density of the ink can really not  be controlled by 
reducing the ceramic particles (fritte as we call it here I 
guess) amount to the ink medium ?  Is the rheology of the 
ink already at the edge of not usable ? If dotgain in the 
total process is hard to handle then a duotone, tritone or 
quad inkset should make it easier to keep the tonal range in 
control but only when the ink itself isn't more compromised 
by the changed pigment ratio. No ink additives possible to 
deal with that issue ?

Do you measure the densities in the final product, a 
greyscale step target on a baked tile ? Measuring on the 
printed transfer sheet is likely not delivering an accurate 
base to make curves on.
