We print in CMYK, so please ensure your artwork is in CMYK. For greater control over the printed output, submit CMYK artwork only. (Example Profile to use PDF/x-1a Coated FOGRA39)
If it is set to RGB, it will be converted to CMYK automatically before printing. However this conversion process may affect your colours.
Please also note that we do not provide a colour management or match service. On occasion, some machine and ink variance may cause a subtle colour difference in the printed output.
