QTR-Quadtone RIP

Paul Roark used/uses a Spyder 3, the Spyder 4 has a price of 160 Euro 
including VAT in Europe, there are even cheaper Spyders at 100 Euro. 
Modern solid state hardware that can do color profiles as well if needed 
and I guess that happens more often than alternative B&W processing. If 
it has to be a spectrometer then the Color Munki can do a fine job, 360 
Euro.

comparable pricing can be found in Belgium.

If the software included is not advanced enough for reflective 
measurements then there is ArgyllCMS with a long list of compatible 
spectro- and colorimeters and the meters above are in that list. Linux, 
Windows, OS-X support.

If it has to be cheaper then a secondhand Spyder or Color Munki will 
still be easier to use and includes Lab a b values that a densitometer 
like the 810 will not deliver.
