<http://en.wikipedia.org/wiki/Phosphor>

"A phosphor is a substance that exhibits the phenomenon of phosphorescence (sustained glowing without further stimulus).

The chemical element phosphorus (Greek. phosphoros, meaning "light bearer") was discovered by German alchemist Hennig Brand in 1669 through a preparation from urine. Working in Hamburg, Brand attempted to distill salts by evaporating urine, and in the process produced a white material that glowed in the dark. Since that time, the term phosphorescence has been used to describe substances that shine in the dark without burning.

Phosphorus itself is not a phosphor; it is highly reactive and gives-off a faint glow upon uniting with oxygen. The glow observed by Brand was actually caused by the very slow burning of the phosphorus, but as he saw no flame nor felt any heat he did not recognize it as burning.

Phosphors are transition metal compounds or rare earth compounds of various types. The most common uses of phosphors are in CRT displays and fluorescent lights."

Interesting, but the question isn't about phosphors. It is about LCD filters that impart the color of red, green, and blue.

Thanks for interesting reading!

Why dont they make monitors in CMYK mode so when I view an image it will be truer to the print?

[Brutus_Maximus@adobeforums.com]

Because printing takes place in subtractive color mode <http://en.wikipedia.org/wiki/Subtractive_color> (i.e., Cyan, Magenta, Yellow, and Black, where C100/M100/Y100/K100 produces a muddy black), while monitors work in additive color mode <http://en.wikipedia.org/wiki/Additive_color> (i.e., Red, Green, and Blue, where R100/G100/B100 produces white).

Because all that ink would drip out of the monitor and onto your desk and keyboard.

But the bigger answer to your question is that you can turn on View> Document Setup to change the display of your monitor to be closer to your final CMYK output.

And remember, not all CMYK is equal. The color C:50, Y: 50 looks very different on newspaper stock than it does on coated paper.
