THE CYAN MAGENTA YELLOW KEY COLOR MODEL

The CMYK color model is used in the printing process. To understand it, it is best to start with RGB color. The RGB color model (made up of red, green and blue) is used in your computer monitor, and is what you will view your projects in while still on screen. These colors, however, can only be viewed with natural or produced light, such as in the computer monitor, and not on a printed page. This is where CMYK comes in.

CMYK in Graphic Design
Graphic designers have to deal with the issue of seeing their work on screen in RGB, although their final printed piece will be in CMYK. Digital files should be converted to CMYK before sending to printers, unless otherwise specified. Because of this issue, it is important to use “swatches” when designing if exact color matching is important. Swatches provide a designer and client with a printed example of what a color will look like on paper. A selected swatch color can then be chosen in Photoshop (or a similar program) to insure the desired results. Even though the on-screen color won’t exactly match the swatch, you know what your final color will look like. You can also get a “proof” from a printer, which is an example of your printed piece provided before the entire job is run.

This ares some basic grammar terms to help you get the whole thing
Adjective : In grammar, an adjective is a word whose main syntactic role is to qualify a noun or noun phrase, giving more information about the object signified.
Adverb: An adverb is a part of speech. Adverbs can modify verbs, adjectives (including numbers), clauses, sentences and other adverbs.
Conjunction: A conjunction is a joiner, a word that connects (conjoins) parts of a sentence.
Interjections: Interjections demonstrate emotion and are usually separated from the rest of the sentence by an exclamation point, and sometimes by a comma if the emotion is less stressed.
Noun: A noun is the name of a person, place, thing, or idea. Whatever exists, we assume, can be named, and that name is a noun.
Preposition: A preposition usually indicates the temporal, spatial or logical relationship of its object to the rest of the sentence as in the following examples:
Pronoun: A pronoun can replace a noun or another pronoun. You use pronouns like "he," "which," "none," and "you" to make your sentences less cumbersome and less repetitive.Verb: The verb is perhaps the most important part of the sentence. A verb or compound verb asserts something about the subject of the sentence and express actions, events, or states of being.
