Can any monitor be used for soft-proofing?

Question: Can any monitor be used for soft-proofing? What are the minimum requirements for accurate onscreen proofing?
— An unidentified reader
Answered by Dan Caldwell, VP, Integrated Color Systems:
Yes and no. It really depends on the software you are using and the degree of color accuracy you expect. Today, viewing onscreen proofs to SWOP certification standards require certain minimum standards.
The basic requirements
The following displays can support SWOP certification conditions: Apple 20", 23”, 30” Cinema Display, Apple G5 iMac, Eizo CG21, CG210/211, CG220/221, LaCie 321, Quato IntelliProof 213
For more information on SWOP certification: http://www.swop.org/certification.html
An emissive measurement device for monitor calibration:
X-Rite / GretagMacbeth EyeOne Pro spectrophotometer
X-Rite / GretagMacbeth EyeOne Display II colorimieter
X-Rite DTP94 colorimeter (also known as the Monaco Optix XR)
Monitor bit depth and resolution:
Color monitor with 24-bit color video card
Minimum display resolution (1280 x 1024 pixels)
Not all monitors are accurate from edge-to-edge. Some applied color science is needed under the hood to create and maintain uniformity. As an example of some of the measurements we must take to measure and compensate for these conditions, Remote Director will set internal look-up tables (luts) at the full bit depth of a supported monitor; will build a luminance map to even out displays that have evenness problems; displays images in virtual 10 bit on an 8-bit only display; profile any number of displays arranged as a monitor wall and connected to a single CPU and apply the individual displays profile to an image that is stretched across all the monitors; provide a luminance history to track the monitors over time and show the wear of the light source.
