Printing on envelopes is just like printing in flat sheets in the sense that both have square corners. However, envelopes are manufactured on specialty equipment which makes use of steel dies and then transferred to high speed machines that affix glue to the seams, fold and then complete the envelope. The only drawback of these operations is its inability to make an envelope that is perfectly square. This poses a challenge for printers to come up with envelopes with type and graphics that straight and true.
Envelope press printing is a service that is usually used for various envelope print jobs that involves the application of extensive color and/or graphics that are usually needed for either personal or business requirements. The process of envelope press printing entails conversion of an envelope from flat sheets which call for the use machinery that first die cuts the sheets and then in a separate operation, scores, folds, glues and then folds them to their final shape. The machines used for this type of procedure normally runs at high speed while the press run requires for careful inspection by the press operator in order to ensure quality in the printed envelopes.
