PDF

A PDF is a container format, not an art format — it can hold a scalable vector illustration built in Illustrator, a flattened raster photo exported from Canva, or some mixture of both on the same page, and the file extension alone tells you nothing about which one you've got. Opening the file and zooming to 800% is the only reliable way to know: paths and text stay crisp, while raster content pixelates into visible squares. Print shops also check whether fonts are embedded or converted to outlines, since a missing font quietly swaps in a system substitute and wrecks a logo's letterforms.

This is the file most buyers actually have, because it's the default export from Word, Canva, PowerPoint, and every design program at once — so a PDF can arrive as flawless print-ready vector art or as a low-resolution screenshot pasted into a page, with nothing in the filename to tell them apart. We've had customers send over a 40-page proposal deck and ask us to print "page 12," when the flattened export underneath was captured at 72 dpi and was never going to hold up at 12 inches across a hoodie.

Ask your printer to open the PDF and confirm vector content before approving final art, especially for large-format prints, single-color spot jobs, or anything with fine text. If a designer built the file, request an export straight from the vector layers rather than a "print to PDF" from a preview window, which almost always flattens everything at low resolution.

The common mistake is treating "PDF" as a quality tier the way people talk about JPEG versus PNG. It isn't — a PDF is only as good as what's inside it, and a five-minute check before production is cheaper than a reprint.
