Important notes on color (CMYK, PMS, RGB, etc.)
| • |
In order for us to print in "full color"
the graphics need to be in CMYK process color at the
proper resolution. |
| • |
Please don't be upset when we tell you your graphics
won't print well because they were designed in RGB colors
that don't convert well to CMYK, or because your images
have too low of resolution because they came from a
website or were made solely for online viewing. |

If you are using a Pantone swatch book to choose
your color, please realize that PMS swatch books are
split between how a PMS color will look on an uncoated
paper and a coated paper. Hence the "U" or
the "C" after the PMS number. As "U"
colors are not always the same as "C" colors,
PMS colors are not always the same as CMYK colors. It
also holds true to CMYK printed on an uncoated paper
versus a coated paper. Many other factors affect how
the colors will look on a finished printed piece. These
variables are found at the beginning section of the
Pantone Process Color System Guide book. |

You must realize that the colors on your screen
may or may not match those on the printed cards. If
you are highly critical of the accuracy of your colors
you must refer to a Pantone Process Color System Guide
book when applying colors in your programs. From this
book, which is a swatch book of 3,000 process color
variations, you can find the color you want with its
corresponding CMYK percentages. These CMYK percentages
must then be entered in to your program and applied
to the art. If you have a PMS number in mind that you
are trying to match, some programs, like Photoshop,
will help to determine the CMYK percentages that will
most closely match the PMS number. If you are using
a Pantone process color swatch book, please read the
front pages' cautions and variables. Even though you
have the numbers plugged into the program, and the film
is output correctly with the proper CMYK percentages,
there are many factor which affect the final printed
color. |

RGB, PMS spot colors, and indexed colors must all
be converted to CMYK. Some do not convert well at all.
|
| • |
Not all RGB or PMS spot colors will covert exactly,
because the color spectrum of 4-color process printing
(CMYK) is different than that of the RGB and PMS spot
colors. Below is a graphical representation
of the different spectrums. The "web" looking
spectrum is the process spectrum, the "triangle"
represents the RGB spectrum, and the rest is the visual
spectrum that our eyes can see in nature. PMS spot colors
also have their own unique shape inside the visual spectrum.
What this all means is starting with a color in one
spectrum and trying to move it to a different spectrum
does not always work.
