Oles Envelope Corporation uses three methods of producing custom printed envelopes: flexography, jet offset printing, and lithography conversion. The choice of a printing process depends upon the size of the run, the complexity and quality of the camera-ready art, the number of ink colors, the paper stock, and the level of quality desired.

FLEXOGRAPHY Flexography is the least expensive and simplest of the printing processes used for envelope printing. It uses special photopolymer plates and water-based inks in an anilox inking system. With significant improvements in recent years, flexography is approaching the quality of lithographic printing. Oles currently produces flexo-printed envelopes on both web and die cut equipment.

JET OFFSET PRINTING Jet offset printing is used to print already manufactured envelopes. Similar to the printing method used in offset lithography on flat sheets, jet printing allows for extremely detailed images and well-controlled color. Oles has quick-turn, short and long run jet printing capabilities and the ability to print from one color to four-color process on any size envelope.

LITHOGRAPHY CONVERSION Lithography conversion is the process in which pre-printed sheets or rolls of paper are converted into envelopes. Unlike jet printing, litho conversion allows for full ink coverage on the envelope. Oles Envelope Corporation is one of the few envelope manufacturers that offer both die-cut and web envelope conversion.
