Offset envelopes are printed flat on offset presses, then die cut and converted into envelopes. For Offset envelopes with bleed on the face or print on any flap, it is required that the artwork be placed on a Envelope Template.
Digital envelopes are pre-converted and printed on high tech digital equipment. They’re available as 4/0 (Full Color on Front – envelope face), 4/4 (Full Color on Back Flaps) and 0/4 (No Color on Front – envelope face and Full Color on the Back Flaps). Full color backgrounds are NOT recommended, it is best to use a white background with low ink coverage, (e.g. logo and text only), the ink coverage should not exceed 40%.
