Which Wins in Digital Imaging - Rgb Or Cmyk?

An existing description on this site called What are Rgb and Cmyk in Photography and Photoshop? explains the separate components of light and how they work in photography. This description considers which mode, Rgb or Cmyk, is more accepted in digital imaging work.

The detach colours are called channels; so Rgb mode has three channels and Cmyk mode has four channels. This means that a 30Mb file in Rgb will be a 40Mb file in Cmyk. A principal estimate of Photoshop work can be done on the individual channels.

An important inquire is should we work in Red, Green, Blue mode or
Cyan, Magenta, Yellow, Black mode?

The riposte is most undoubtedly in Rgb mode for the following reasons:

Images are originally made in Rgb. All images are scanned in Rgb. All scanners work in Rgb.If Cmyk is offered as an option, it is because the scanner has done a conversion. All digital images are created in Rgb. Even though they use Cmyk inks, desktop inkjet printers are Rgb devices.They accept an Rgb file, which they turn to Cmyk for printing.Send such a printer a Cmyk file and it will turn it to Rgb then turn it back to Cmyk. Rgb has a wider gamut (range of colours) than Cmyk. Rgb colours are displayed according to digital numbers and are not dependent on the carrying out of any device, such as a monitor. Rgb files have three channels; Cmyk files have four channels, therefore wish more memory. The final appearance of Cmyk colours is dependent on the characteristics of the printing process.There is a large collection of Cmyk colour spaces. Until all the details about the printing process are known, Cmyk colours will not be accurate for screen work.Cmyk are ink colours for printing and a Cmyk image will not be accurate until it is proof-matched.

Ever wondered why it's K for Black in Cmyk - Cyan, Magenta, Yellow, Black? Probably not, but I'll tell you anyway.

It is said the custom was started by German printers and stands for 'Kompensation' (compensation) because the black corrects the inadequacies of the Cmy inks; cyan, magenta and yellow inks being insufficient to make a good black on their own.

So now you're asking, why not G for Gelb, as in yellow, right? But that would confuse with Rot, Grun, Blau. Similarly, the letter B would have been confusing, because of Rgb. So we end up with a bit of an amalgam.
