QTR-Quadtone RIP

Hi Leen

if you drop me an email, I'll be able to get my ink seperation page 
to you, along with some useful tips on how to use it. Are you aware 
that you need a second colour printer inorder to print out the TID 
and RID strips before printing the seperation page from within QTR, 
and it's rather intricate since you need to create a target via 
colorport, but it can be done. For most people I would imagine it is 
all to much trouble, and I would agree, but It suits me just fine as 
I'm interested to see what each ink is made up of in terms of Lab a 
and b (and how the values drift over time.) Anyway, enough of my 
ranting; if you want me to help you to try and do it yourself, just 
get in touch,

Jamie
