Hi Steve, Finally, this discussion is getting somewhere, and I thank you for the contribution. But, we are not quite there yet, if you please.

But in any event the total number of displayable colour that the human eye can perceive does not exceed 16.7million colours irrespective of there combination. The PowerBook G4 displays 16.7million colours (combinations!) so does the cinema display. > > so, even though each of the displays has 16.7 million addressable RGB values, > the Apple HD Cinema Display can display almost 410,000 more colours.

Perhaps, but in most circumstances the additional gamut is not required. Bear in mind that colour judgement is somewhat subjective, so if an observer is pleased with the range of colours he perceives using any VDU and he can reproduce them as accurately as he perceives them with "his desktop printer such as Epson 2100" then such additional gamut offered by the cinema display is "luxury". It is like my Canon cooker that rings and whistles and more but only gets used as the basic cooker, 99.99% of the time. >From your website you wrote: > > any profile can be applied to those Lab values to get the color you want. In this case, we want the color to go to your printer. When the printer profile is applied it formulates the correct CMYK settings for each color in your file. A good quality profile will do a great job of matching those colors within the abilities of the printer. > This is exactly what the supplied profiles that comes with Epson 2100 does, and if you set it up correctly you certainly don�t need a super screen such as the cinema display. Do you agree? Regards, Inno' =============================================================== GO TO http://www.prodig.org for ~ GUIDELINES ~ un/SUBSCRIBING ~ ITEMS for SALE
