Cyan, magenta, yellow, and key (black)
For web designs you would you an RGB color format. For things like poster printing you would use CMYK. Also CMYK is the typical printing process used for production.
L1 is black or the hot wire and L2 is white or the netural wire
There are two basic colorspaces for art: RGB and CMYK. (Yes, I know about LAB color, index color, and all the other settings you can put a file into. Let's stick to RGB abd CMYK.) Printing on a press, or a pro inkjet, is done in CMYK because the inks are cyan, magenta, yellow and black (black ink is also called "key") and if you set your Photoshop separation settings up right, you can convert a file to CMYK and have a very good idea of what it'll look like on the sheet. If you send an RGB file through your system to your imager, one of three things will happen; which one happens depends on your system. On a very old system, there won't be any colorspace conversion and you'll get a grayscale photo where you thought there was supposed to be a color one. If you have a newish system that automatically converts RGB to CMYK, and you've got it set up right with the exact ICC profiles you need and you have really good color-corrected art, you'll get a result that will look good. Most of us don't have it like this, because most of us separate the art in Photoshop. If you DON'T have the system set up like in the last paragraph, the system will convert art from RGB to CMYK but the finished product will be dull and lifeless. So...in relation to the printing process, RGB means Bad News if it gets all the way to plate that way.
Officejet printer ink consists of four main color groups. that can be mixed to create all visible colors. Their main colors consist of black, yellow, blue, and red.
orange green and white.
The dominant colors are red and yellow in the following CMYK delineations.Red: CMYK (%) 0-90-80-5Yellow: CMYK (%) 0-15-95-0There is also the seal of the Kingdom of Spain, which has numerous colors on it.
CMYK stands for Cyan, Magenta, Yellow, and blacK, which are the four colors of ink used in standard color printing. A CMYK code is a set of four numbers representing the proportions of those four colors of ink, thus defining a color to be printed.
K is used to represent Black in CMYK because B is already used for Blue in RGB.
The main difference between CMYK and RGB color models is how they create colors. CMYK is used for printing and uses cyan, magenta, yellow, and black inks to produce colors. RGB is used for digital displays and combines red, green, and blue light to create colors.
Screens reproduce colors by mixing blue, green and red lights (RGB). Printers reproduce colors by mixing cyan, mangenta, yellow and black inks (CMYK).
Pantone is system used to standardize color matching. Pantone colors are referenced by the TPX code. To convert Pantone TPX to CMYK, select an item, and then select "convert to CMYK" on the "edit" menu.
First check resolution from Image - Image Size, then convert to CMYK colors from Image - Mode - CMYK

EndsSo enjoy with CMYK colorsHope it helpsCheers--------------------------------
well, let me try to explain the answer i am sure that you will reach to the answer... RGB and CMYK are different colour system. RGB Stands accordingly as Red, Green and Blue and CMYK stands accordingly as Cyan, Meganta, Yellow and Black. * RBG colour system is based on "The colour of light Rays" and * CMYK colour system is based on "The Reflection of light Rays" The Reflection of light is always dull than actual light so CMYK make the colors go dull.... - mayur_vaghela@yahoo.co.uk
For standard presses, the four color process can create one million colors.
The four colors used in process color printing are cyan, magenta, yellow and key (black) or CMYK.
Printers use CMYK instead of RGB because CMYK is a subtractive color model that is better suited for printing on physical surfaces like paper. CMYK stands for cyan, magenta, yellow, and key (black), and these colors are mixed together to create a wide range of colors on printed materials. RGB, on the other hand, is an additive color model used for electronic displays like computer monitors and TVs.
