FAQ (Frequently Asked Questions) about
Spectrophotometers/ Color Management:

What is the difference between a Spectrophotometer and a Densitometer?
In short, a Densitometer measures RGB or CMYK density values, a Spectrophotometer measures spectral data from which colorimetric data (L*a*b*, XYZ etc.) is calculated. In addition, a Spectrophotometer can also be used as a densitometer, but not vice-versa.

Can I use a Densitometer for Color Management?
No, color management is based on colorimetric values (L*a*b*) which is only measured by a Colorimeter or Spectrophotometer.

Profile-Xpert
Can I use the created ICC profiles both on Mac and on PC?
Yes, the profile itself is the same. 
If you have created a profile with the Mac software and want to use it on a PC, it must be named with the extension ".ICM" in order to be accepted by the PC. 
If the profile was created with the Windows software and you want to bring it to the Mac, then you need a utility to set the file format to "prof" in order for the Mac to recognize the file as a profile. please see the Profile-Xpert CD under "utilities".

If I have more than one scanner, do I need to buy more than one Profile-Xpert Scan software?
No, you need only 1 Profile-Xpert Scan for all of your scanners. The profiles must not be created on the scanning workstation, they are just used there after creation. 

If I have more than one output device, do I need to buy more than one Profile-Xpert Print software?
No, you need only 1 Profile-Xpert Print (3c or 4c) for all of your printers of same tecnology (3c or 4c). The profiles must not be created on the output workstation, they are just used there after creation.
