Yes. Some PDF files are layered, and some are flat. “Layered” means it is made up of layers of text and images, and “flat” means it is just one big picture of pixels. How to easily tell the difference: on a layered PDF you can highlight text for copy and paste, but on a flat PDF you can’t highlight and select any text because it’s just one big picture.
The solution is easy. After you have filled out the form, flatten the PDF before uploading it to Postalocity. This can be done in various ways. If you have a program that has a “flatten image” option, you can try that, but we have seen remnant problems where these are not fully flattened, and problems remain. You can try it, then check it carefully in the Postalocity approval process to see that everything looks right.
The surefire way to flatten the image is print it to a printer, then scan it back in as a PDF file. Black and white works nicely; color scanning can leave a grayish background, but it will be flat in any case.
Now you can mail it easily through Postalocity, with one caveat: because it’s a flat image now, Postalocity cannot use a capture zone to read the address. All you have to do is manually enter the recipient address, and you’re good to go!
