Color is all around us. It is asensation that adds excitement and emotion to our lives. Everything from theclothes we wear, to the pictures we paint revolves around color.

Without color,the world would be a much less beautiful place. Color can also be used todescribe emotions; we can be red hot, feeling blue, or be green with envy. Inprint, the Four Color Process, also known as CMYK. CMYK four-color printing isable of reproducing literally thousands of colors. This is the industrystandard method of produce all color magazines, books, and other full colorprinted material. For example, to get a GREEN color from the four basic primaryprint colors, the industry uses CYAN and YELLOW that mix to give GREEN. Theexact of tint may require different percentages of each color to form the basicGREEN, and enhanced by adding a small percentage of the other primary printcolors. Although the actual color used isdifferent, all printing, and in fact motion picture and television, all dependon the analog system that builds a rainbow from a few basic colors.

All lightmediums use the primary colors associated with light Red, Green, Blue (alsoknown as RGB). The software used in the print industry also use the RGB colorformat which is on different specter then CMYK. Since the files made in RGBformat will not look the same as in the setup software when printed with theCMYK format, it is advisable to change the image or file to CMYK before sent toprint. Television and computer monitors create full-color images with lightprojection using the primary colors of light. Thousands of colors can becreated from three RGB primary colors (Red, Green, and Blue). This phenomenonis called additive color. In other words, add 100% of the three colors togetherand you produce white.

The absence of all three black leaves colors.To illustrate additive color, youhave imagined three spotlights, one red, one green and one blue are focused onthe back of an ice arena on skaters in an ice show. Where the blue and greenspotlights overlap and the color cyan is produced where the blue and redspotlights overlap then the color magenta is produced where the red and greenspotlights overlap the color yellow is produced. When the colors addedtogether, red, green and blue lights produce what we perceive as white light. As mentioned before, televisionscreens and computer monitors are examples of systems that use additive color.Thousands color of red, green and blue phosphor dots make up the images onvideo monitors.

The phosphor dots expend light when activated electronically,and it is the combination of different intensities of red, green and bluephosphor dots that produce all the colors on a video monitor. Because the dotsare so small and close together, we do not see them individually but see thecolors form in the mixture of light. Colors often vary from one monitor toanother.

This is not new information to anyone who has visited an electronicsstore with various brands of televisions on display. Also, colors on monitors canchange over time. Currently, there are no color standards for the phosphorsused in manufacturing monitors for the graphics arts industry. All imagecapture devices use the additive color system to gather the information neededto reproduce a color image. These devices include digital cameras, flatbedscanners, and video cameras.Then, printing presses create afull-color image with light reflection using a slightly different three primarycolors (Cyan, Magenta, and Yellow). A fourth color is added to improve contrastand definition in the image and to create a sharper text.

The process issubtractive and is usually referred to as CMYK printing. In theory, add 100% ofall three colors (CMY) together and you produce black. The absence of any colorleaves only the paper color which is generally white. In actual fact, the blackproduced by combining cyan, magenta, and yellow is more like a dark muddybrown, which is why the fourth color, black, is added for better colorappearance and to make it easier to print, most of which is generally black. Ifconfused, a highly useful tool for selecting reproducible CMYK colors is thePantone Process Color Guide. This swatch guide displays over 3,000 colors withthe corresponding color build and is available on both coated and uncoatedstock.

Strongly recommended if you will be doing repeat printing projects orhave color concerns.However, we really do live in afour-color world, and this simple, if the surprising point, is exactly whatmakes CMYK 4-color process printing possible. Full-color printing, oftenreferred to as “CMYK” or 4-color printing, reproduces a comprehensivephotographic color spectrum using the combinations of four basic ink colors -Cyan, Magenta, Yellow, and Black. Artwork and color photographs, once “separated”into their CMYK components, can be reproduced combined the four basic inks toprovide a finished product which is virtually different from the original.

Allcolor of brochures, flyers, catalogs, magazines, posters, menus book, etc. areprinted using this method. For metallic, fluorescent and some specific PMS(Pantone Matching System) colors cannot be reproduced with the CMYK process,many of our printing presses offer 5, 6, 7 & 8 colors capable to allowadding “spot colors” or other special inks to be printed in additionand at the same time, as the four CMYK colors. According to a printing company, inyears ago by the CMYK printing process was very complicated and expensivebecause of the high cost of manually creating color separations and theproduction of print film and film proofs used in making printing plates. Ourstate-of-the-art pre-press department, however, uses advanced CTP (Computer toPlate) technology that eliminates the high cost of producing color separations,print film, and film proofs. Now you can afford to take advantage of the highimpact, professional quality images that full-color printing brings to yourgood marketing and can make the high promotional material.In order to understand color, lightis made up of energy waves which are grouped together in what is called aspectrum. A light that appears white to us, such as light from the sun, isactually composed of many colors.

The wavelengths of light are not colored, butproduce the sensation of color. Without light, there would be no color, andhence no colorful world. Thank God for the light!
