When designing your cards you want to make sure there is at least a ¼” room so that the cards can easily be inserted into the envelope. In addition, if you are sending out over 1000 invites; you want to make sure you use a machine insertable announcement envelope and you should consider using a mail house for the actual mailing. This will save your business substantial time and money.

Determining the type of card stock to be used is based on the type of invite and/or announcement. With Christmas and Thank You cards you would typically use either 10PT C1S or 12PT C1S cover. This cover stock has a glossy finish on the outside and uncoated stock on the inside. This allows you to hand write a note on the inside of the holiday card. For a business announcement, you would either use a gloss stock (like 10PT C2S or 12PT C2S) if there is no RSVP card. If you need a matching RSVP card and envelope then it’s recommended that you use a silk or matte cover stock. This type of cover stock has a coating, but is not as shiny as gloss and is easier to write on. Formal wedding invitation printing is normally done on a premium uncoated stock like Classic Crest from Neenah.

Consulting with a professional print company and mail house is the best recommendation to make sure your formal invitation printing project is designed and executed correctly.
