We are applying fugitive glue to close a flap on a mailer. The customer mails these over a four-week period. The customer is complaining that after a couple of weeks a stain appears in the ink on the cover opposite the glue strip. What is happening?

Fugitive glue contains a large amount of plasticizer to keep it pliable. This plasticizer is penetrating the stock and staining the ink on the cover. The plasticizer can even soften dried ink and cause it to smear. Discuss this with your ink maker and glue supplier, and consider a less porous stock.
