Customer Questions
We can do Security Envelopes but these will be done by our Custom Department. We would request you to create an account online and give us a call to speak to a Custom Representative so they can send you a quote.
The lines mentioned will need to be included in your file just like all the other design elements you need us to print. We cannot add or delete any element from a client's file or make any assumption without informing the customer or if they directly advise us to.
Just to clarify the templates are not design templates that provide sample artwork or content related to specific industries or design ideas. The templates will only show the trim lines, safe zone and exact file size which will guide users on how to set up their original designs.
We do have a service for ink jetting the names and addresses you need on the envelopes. However, we dont print the Intelligent Mail Barcode (IMB).
Your files will be reviewed for printing errors without paying a cent.
