We will need to get Artwork Approval from Royal Mail the first time.

For first time orders (with a new licence number) the artwork proof must be sent to Royal Mail for sign-off and approval - whether creating the design yourself with our Template Design Editor or supplying your indicia for us to set up.

To speed up the process and, more importantly, make things easier for you, we'll send the artwork to the Royal Mail on your behalf to get "Copy Approval" the first time you're getting them printed. Once approved, we will then send it to production to be printed.

If you're supplying your own hi-res PDF artwork that you have previously used we can bypass the approval stage (as the artwork would have already been approved) and can proceed straight to production.

What is a PPI Prepaid Envelope?

PPI prepaid envelopes ('Postage Paid Impression' or "Printed Post Impression") are a convenient pre-printed alternative to using stamps or franking machines for companies who have medium to high volumes of post being sent out.

These pre paid envelopes from various carriers including Royal Mail, include a pre-paid postage mark or impression that allows the company to pay for the postage cost in advance, usually at a big discount over using stamps or a franking machine.

PPI is perfect for posting out Letters or Large oversize Letters such as C4.

TradePrintingUK are one of the specialist UK printing companies that can print these pre paid PPI envelopes in full colour for you, once you've got your licence with your carrier.

Used to post out business letters, statements, invoices and bills, surveys, customer or member questionnaires or application forms.

What are PPI Prepaid Envelopes used for?

PPI prepaid mailsort envelopes are typically used for posting items such as surveys, customer or member questionnaires, application forms, letters, statements and invoices, and other types of correspondence that require a response from the recipient.

What size are prepaid envelopes?

They are normally "oversize" versions of popular sizes, including DL+ and C5+.

In the UK these sizes are DL+ (235mm x 114mm) and C5+ (162mm x 229mm). They can come with a variety of postage marks or impressions, depending on the specific needs of the sender and the carrier used.


Royal Mail's most popular Prepaid products would be an Mailsort or Unsorted Account Barcode PPI"

What type of flap can I use on PPI Pre-Paid?

From an over-printing perspective, we normally only produce PPI Pre-Paid Printed envelopes via our now standard, 90gsm Gummed Machinable product range for quantities ranging from 100 - 10,000.

This uses a special flap for automated mailing machinery with automatic insertion (Fulfilment) operations that can read machine-readable PPI letters and large letters, plus the single indicia in the top right (called a PPI, pre-printed stamp) for either 1st Class or 2nd Class PPI prepaid envelopes, sent via Royal Mail within the UK.
