notes on color (CMYK, PMS, RGB, etc.)
- We produce our
color separations using a standard SWOP profile. We will then match
SWOP densities within a reasonable tolerance.
- In order for us
to print in "full color" the graphics need to be in CMYK process
color at the proper resolution. Spot color jobs must be separated properly.
- Please don't be
upset when we tell you your graphics won't/didn't print correctly because
they were designed in RGB colors which 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
- If you are using a Pantone swatch
book to choose your color for spot color jobs, 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. 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 book.
- Pantone spot colors are not
always simulated in CMYK closely. CMYK printed on an uncoated paper
versus a coated paper will also produce visual differences. You must
realize that the colors on your screen may or may not match those on
paper. We recommend the use of Pantone Color Bridge swatches to see the solid to process simulation differences.
- If you are sensitive to the
accuracy of your file's color you should refer to the appropriate Pantone
swatch book. If you are referencing a Pantone swatch book, please read
the front pages' cautions and variables. Even though you have the numbers
plugged into the program, and the color is separated correctly, there
are many factors which affect the final printed color.
- RGB, PMS spot colors, and indexed
colors must all be converted to CMYK for full color printing.
- Not all RGB or PMS spot colors
have good CMYK simulations, 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 that starting
with a color in one spectrum and trying to move it to a different spectrum
does not always produce desirable results.
