Heavy Ink Coverage Explained for Printed Envelopes

SPECIAL NOTES: — Ink will run if it gets wet!

Colour saturation on Printed Envelopes!

CMYK (Cyan, Magenta, Yellow and Black) are the colours used in the printing process, whereas RGB (Red, Green and Blue) are the colours used by screen displays such as your monitor or iPhone/Android.

For this reason and due to variations introduced by light and various equipment, the colours on your screen may not exactly match or have the saturation of colours of a printed product. Like all printing companies, we print in CMYK which means there can and will be a colour variation on printed material.
