I am concerned about the colours in my design, what do I do?

If you are worried about the colours of your artwork we suggest ordering a sample print.

You can set up variations of your artwork on an A3 so you can see which version of the artwork performs best. Remember that the colours in digital printing vary slightly.

Ensure you convert all RGB colours to CMYK. This is vital for your job to
produce desirable results.

• Please allow for a difference in colour between what is shown on your
  screen and what is printed. When printing in CMYK (Cyan, Magenta,
  Yellow, Black), various factors will affect the colour result.
• You can't tell exactly how colour will digitally print by comparing it to what you see on your screen. Every screen is different, and every printer prints each colour
  differently.
• We colour calibrate our digital presses daily to minimise colour variation.
  However, consistency is not guaranteed, this is simply the nature of
  printing in CMYK. There is potentially a 5% variance in colour from the
  first proof to the final product.
• Never underestimate the difference a stock can make to your colours.
  When choosing a colour please take into account what stock it will be
  printed on.
