RGB is the colour gamut used to display images on computer screens, and stands for RedGreen and Blue

CMYK is the colour gamut used for conventional printing, and stands for CyanMagentaYellow and Black.

Pantone Spot colour is a special premixed ink, similar to mixing paint such as blue and yellow to get green but with much precision.

Because RGB uses light,
the more colours overlap the whiter they get and appear a lot
lighter on screen appearance.

Because CMYK uses inks,
the more colours overlap the blacker they become.

Because Spot Colours are premixed,
they can produce more vibrant results.

Why does my Print ready artwork need to be CMYK?

The RGB colour spectrum is much larger than CMYK, and if you supply artwork as RGB, what you get when it’s printed may differ markedly from what you supplied. Most colours will be much the same, but bright colours will appear duller, particularly greens, blues and pinks. Before you save your file, make sure you have converted it to CMYK so you will have a truer idea of what it will look like when printed.

We recommend against producing your designs in these packages,
but where unavoidable, we recommend to avoid the bright primary neon type colours as those will change radically.

It’s important that you set your colour mode to CMYK before you

start designing your artwork.

If you create your artwork and then convert your RGB or Spot Colours
at a later stage, then your colours may be negatively affected.

Our system will automatically convert RGB and Spot Colours
to the closet possible CMYK colour.
