COLOR, What you need to know (CMYK
When creating and supplying digital art files it is important
to understand the media in which it is intended to be used, and that you
supply images and graphics in the correct mode or color space to insure that
colors will reproduce correctly.
For Printing Presses: The color mode is either Black &
White (Grayscale), Spot (PMS) color(s) or for
color printing the CMYK.
For Digital Printing (laser and inkjet): The color mode is Black &
White (Grayscale) or the CMYK.
Internet or Screen Viewing: The color mode is RGB.
Most design software
packages will provide for this. However, a scanned picture or image taken
with your digital camera will normally be saved in RGB mode unless otherwise
specified. In addition, computers display images on screen as RGB.
RGB - RGB
stands for Red, Green and Blue. These are the primary colors of light that
when combined create other colors and white. This is the color model used
for television and/or computers display images.
The RGB color model,
is an additive model, whereas
white is the “additive” combination of all
colored lights, while black is the absence of light. If we combine
red, green and blue light you will get white light.
background absent of color

Chart (Pantone to RGB and HEX)
used to describe the printing process itself, is just the opposite of RGB.
CMYK is a
“subtractive” color model that works by partially or entirely masking
certain colors on the typically white background, because inks “subtract”
brightness from white.
White is the
natural color of the paper or other background, while black results from a
full combination of colored inks.
CMYK = C –
Cyan (Blue), M – Magenta (Red), Y - Yellow, K – Key (Black)
The “K” in
CMYK stands for key since in four-color printing cyan, magenta, and
yellow printing plates are carefully keyed or aligned with the key
of the black key plate.
When we print cyan,
magenta and yellow inks on white paper, they absorb the light shining on the
page. Since our eyes receive no reflected light from the paper, we perceive
is "4-color process" or "full-color" printing. By
combining different percentages of the 4 CMYK inks, which under
magnification are seen as round dots of various dimension and spacing, the
illusion of a continuous tone image is created.
It is possible to see colors
in RGB that you can't make with CMYK?
Unfortunately not all colors in the RGB spectrum can be replicated in CMYK.
Such colors are said to be "out of the CMYK color gamut". When converting
from RGB mode to CMYK mode, software programs get as close to original
colors as possible. Some colors convert very well whereas others do not.
reason it is best if you do the RGB-to-CMYK Conversion, where you control
the conversion, from RGB to CMYK before sending them to us.
Scanners and digital cameras generally create images using combinations of
the three RGB colors. When you save a scanned picture, or image taken with
your digital camera, it normally will be saved in RGB mode unless otherwise
When we receive RGB
images, we do a standard-value conversion to CMYK, which may not be
perfectly to your liking. We want you to be happy, so please, take the time
to prepare your file properly. We cannot be responsible for sub-par results
if you furnish your images in RGB. Even though monitors always use RGB to
display colors, the colors you see on your monitor will more closely match
the final printed piece if you are viewing them in the CMYK color space.
CMYK Color Space
Use the following menu
options: Window/Swatches and Window/Color. Double click color in Swatches
Change color mode to CMYK and color type to Process. Any colors created in
the document that are not in the Swatches palette, need to be changed to the
CMYK color space. Select each object you want to convert and make sure the
Color palette reflects the CMYK percentages. Click top right arrow in the
palette to change to CMYK if necessary. Remember to send us your layout and
Adobe Pagemaker 6.5
following menu options: Window/Show Colors. Double click "colors" in palette
and select Model to be CMYK and Type to be Process. Please be advised that
Pagemaker does not successfully represent CMYK color on the monitor.
The following programs do not have the capability to convert to CMYK. No
worry, we will convert it for you free of charge!
Select File/Document color mode/CMYK color
the file already exists select the following menu options: Image/Mode/CMYK
When starting a new file select CMYK for the mode before clicking OK.
Corel Draw 9
Select each object you want to convert. Select the Fill tool and click Fill
Color Dialog. Make sure the Color model is CMYK. For each object with an
outline: Select the Outline tool and click the Outline Color Dialog. Make
sure the Color model is CMYK.
Quark Xpress 4.1
the following menu options: Edit/Edit Colors/Show Colors in Use/Highlight
Color and click Edit. Change model to CMYK and deselect Spot color. Remember
to send us your layout and linked images!
Microsoft Publisher 2000
Microsoft Publisher defaults to RGB. It is
easy to convert everything to a CMYK color space or to start a new document
using the CMYK color space.
the following menu options: Tools/Commercial Printing Tools/ Color Printing
and select Process colors (CMYK). Please note that all images incorporated
into a layout need to be linked and not embedded in order to maintain the
CMYK color space within the image. Using the following menu options does
this: Tools/Commercial Printing Tools/Graphics Manager and highlight the
embedded image. Click Link and click Browse to locate the original file and
link to it. You will then need to send both the images and the layout file
to us for printing.
