“Spend your money wisely” is a saying that has been around for quite a while. When planning a mailing, be it a postcard or a letter in an envelope, that phrase should ring out loud and clear. Spending your money wisely can mean picking the right size mailing to take advantage of the best postal rates. (Just a note, all of this information is available on the Printing Partners website)
Letters or actually envelopes, can affect your mailing rates.
We talked about aspect ratio in the last article (length divided by width) for a mailing piece. This applies to envelopes as well as postcards (the aspect ratio still must fall between 1.3 and 2.5). Most standard envelopes (A2, A6, A7, A8, A10, #9 6 ¼, 6 3/4 and #10) will fit into the USPS letter category without a problem. It is the specialty envelope that can create a problem. As an example a square envelope will fail the aspect ratio test, so it will have a non-machinable surcharge. So watch the aspect ratio before you spec an envelope.
Colors can create a problem as well. Remember the USPS uses an automated system to read addresses, if there isn’t enough contrast or too much black in the color of the envelope, it may fail a reflectance test and then be given a non-machinable surcharge. If you are not sure, get a sample and talk to us prior to designing your piece. We can send the envelope down to the USPS and they can test the color to make sure it is readable by the scanners.
Weight. With envelopes weight can be an issue. In order to qualify for the letter rate, it must weigh 1 ounce or less and have a maximum thick ness of a quarter inch. Although paper is relatively light, it can reach 1 a weight of 1 ounce quickly. If you aren’t sure, we can put together a dummy and weigh it for you. Although it won’t have the weight of the ink, it will give you a ballpark idea before you get too far into your project.
Scanner read area. The USPS has specifications on where you can print on an envelope and where you can’t. The 4.75 inch width and 2.75 height area (as measured from the bottom right corner of the front of the envelope) is a no graphics print zone.
If you do a lot of letter mailings, the USPS has a template with all of their rules and specifications imprinted on it. This is available for free, just go to your local post office and ask for them. Some of the smaller branches may not have them, but should be able to get them or direct you to where you can pick them up. They are a great help in laying out your envelopes and designs.
If you ever have any questions about what is acceptable and what is not, please do not hesitate to contact your salesperson.
