Do your colors need to be exact? Then you want spot color.
Can they be close? Then you want four color process or full color.
If you would like exact Pantone (PMS color matching). You want spot color.
1st Spot Color
2nd Spot Color
3rd Spot Color
Spot color graphics are produced by printing one color at a time. This
process is primarily used in the screen printing process. The inks used
in spot color printing are opaque and are referenced by the
Pantone Matching System
(PMS) for color accuracy. There is no limit to the number of spot
colors that can be printed to produce a final image. The only
restriction in spot color printing is by the printing process itself and
the product in which it is being applied to. Since each color is printed
individually, there may be a shift in color from one color to the next.
This is referred to as registration and varies depending on the process
and products being printed. For instance, it would be likely that it
would be possible to print six spot colors on flat items such as a sign
or t-shirt and obtain good registration between the colors as opposed to
printing six spot colors on a cylinder shaped item such as a sports
bottle or coffee mug where there will be more shift between the colors
and is more difficult to maintain good registration.
FULL COLOR (FOUR COLOR PROCESS)
4 color process is just as it is named. A process of printing 4
transparent colors (inks) to achieve a full color or
photographic image as illustrated above. These colors are
layered over one another which produces the entire range of
colors that make up the final image. There are different
printing processes which use 4 color process to reproduce
images. The most common are digital printing and offset
printing. While offset printing is specifically used for the
printing of paper products, digital printing is growing and
expanded it's capabilities almost daily. Currently, offset
printing is more cost effective for large quantity runs of such
things as books, magazines and catalogs. Digital printing is
much more flexible and allows for cost efficiency in smaller and
even single printed items.
4 color process images can be reproduced from raster or vector
graphics. Raster graphics are generally required to be at least
300 dpi (dots per inch) to reproduce clearly with 4 color
