Color print. Television and computer monitors create full-color

Color is all around us. It is a
sensation that adds excitement and emotion to our lives. Everything from the
clothes 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 to
describe emotions; we can be red hot, feeling blue, or be green with envy. In
print, the Four Color Process, also known as CMYK. CMYK four-color printing is
able of reproducing literally thousands of colors. This is the industry
standard method of produce all color magazines, books, and other full color
printed material. For example, to get a GREEN color from the four basic primary
print colors, the industry uses CYAN and YELLOW that mix to give GREEN. The
exact of tint may require different percentages of each color to form the basic
GREEN, and enhanced by adding a small percentage of the other primary print
colors.

Although the actual color used is
different, all printing, and in fact motion picture and television, all depend
on the analog system that builds a rainbow from a few basic colors. All light
mediums use the primary colors associated with light Red, Green, Blue (also
known as RGB). The software used in the print industry also use the RGB color
format which is on different specter then CMYK. Since the files made in RGB
format will not look the same as in the setup software when printed with the
CMYK format, it is advisable to change the image or file to CMYK before sent to
print. Television and computer monitors create full-color images with light
projection using the primary colors of light. Thousands of colors can be
created from three RGB primary colors (Red, Green, and Blue). This phenomenon
is called additive color. In other words, add 100% of the three colors together
and you produce white. The absence of all three black leaves colors.

To illustrate additive color, you
have imagined three spotlights, one red, one green and one blue are focused on
the back of an ice arena on skaters in an ice show. Where the blue and green
spotlights overlap and the color cyan is produced where the blue and red
spotlights overlap then the color magenta is produced where the red and green
spotlights overlap the color yellow is produced. When the colors added
together, red, green and blue lights produce what we perceive as white light.

 

As mentioned before, television
screens and computer monitors are examples of systems that use additive color.
Thousands color of red, green and blue phosphor dots make up the images on
video monitors. The phosphor dots expend light when activated electronically,
and it is the combination of different intensities of red, green and blue
phosphor dots that produce all the colors on a video monitor. Because the dots
are so small and close together, we do not see them individually but see the
colors form in the mixture of light. Colors often vary from one monitor to
another. This is not new information to anyone who has visited an electronics
store with various brands of televisions on display. Also, colors on monitors can
change over time. Currently, there are no color standards for the phosphors
used in manufacturing monitors for the graphics arts industry. All image
capture devices use the additive color system to gather the information needed
to reproduce a color image. These devices include digital cameras, flatbed
scanners, and video cameras.

Then, printing presses create a
full-color image with light reflection using a slightly different three primary
colors (Cyan, Magenta, and Yellow). A fourth color is added to improve contrast
and definition in the image and to create a sharper text. The process is
subtractive and is usually referred to as CMYK printing. In theory, add 100% of
all three colors (CMY) together and you produce black. The absence of any color
leaves only the paper color which is generally white. In actual fact, the black
produced by combining cyan, magenta, and yellow is more like a dark muddy
brown, which is why the fourth color, black, is added for better color
appearance and to make it easier to print, most of which is generally black. If
confused, a highly useful tool for selecting reproducible CMYK colors is the
Pantone Process Color Guide. This swatch guide displays over 3,000 colors with
the corresponding color build and is available on both coated and uncoated
stock. Strongly recommended if you will be doing repeat printing projects or
have color concerns.

However, we really do live in a
four-color world, and this simple, if the surprising point, is exactly what
makes CMYK 4-color process printing possible. Full-color printing, often
referred to as “CMYK” or 4-color printing, reproduces a comprehensive
photographic 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 to
provide a finished product which is virtually different from the original. All
color of brochures, flyers, catalogs, magazines, posters, menus book, etc. are
printed 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 allow
adding “spot colors” or other special inks to be printed in addition
and at the same time, as the four CMYK colors.

According to a printing company, in
years ago by the CMYK printing process was very complicated and expensive
because of the high cost of manually creating color separations and the
production of print film and film proofs used in making printing plates. Our
state-of-the-art pre-press department, however, uses advanced CTP (Computer to
Plate) technology that eliminates the high cost of producing color separations,
print film, and film proofs. Now you can afford to take advantage of the high
impact, professional quality images that full-color printing brings to your
good marketing and can make the high promotional material.

In order to understand color, light
is made up of energy waves which are grouped together in what is called a
spectrum. A light that appears white to us, such as light from the sun, is
actually composed of many colors. The wavelengths of light are not colored, but
produce the sensation of color. Without light, there would be no color, and
hence no colorful world. Thank God for the light!
