Re: [Digital BW] Densitometer or Spectrophotometer?

2003-03-31 by Dimitri Katsaros

Yes, but if you recall, I did specify that you forget about price 
differences. So, the spectrophotometer I had in mind was the 
Spectrolino. Alternatively, the people at X-Rite suggested the 508, 
but the downside with the 508 is that it cannot be used with a 
monitor (to my knowledge) nor can I see a way for it to be fitted to 
a device similar to the spectroscan. OTOH, the 508 is slightly more 
accurate (0-2.0D +/-.005D and 2.0-2.5 +/-.010D).
