Re: [Digital BW] ICC v. Transfer Function in Epson driver

2005-10-24 by Brian Ellis

Thanks Steve. You said "Any spectrophotometer
that can export Lab data to a text file will work fine."  I've looked on 
ebay and see a whole bunch of spectrophotometers for sale. I know nothing 
about spectrophotometers so please bear with me here. I'm unclear how to go 
about determining whether any particular one  will "export lab data to a 
text file" and otherwise will work with QTR. The obvious answer is "ask the 
seller" except that the sellers talk about sampling paint and things like 
that, certainly not QTR or even photography. Is there some magic question I 
could ask  that is likely to be understood by the typical stectrophotometer 
owner or is transmitting Lab data such a common function of a 
spectrophotometer that most of them would know what I'm talking about?

Thanks for any help you or anyone else can give. I already have a useless 
transmission densitometer  sitting in my garage. I don't want to add a 
spectrophotometer to the collection if I can avoid it.

The i1 is not the only equipment that can be used.  Any spectrophotometer
that cab export Lab data to a text file will work fine.  You just need to
get the data in the right shape which is quite easy and can be done in a
simple text editor.

A densitometer will work if you are simply interested in tonal range
management.  A spectrophotometer is needed to soft proof hue.

No it is just for B&W.
