Is your file print-ready?

The number one worry before any job: will it print right? Drop in an image to check its resolution for your print size, then run the quick checklist. Everything happens in your browser — your file is never uploaded.

1. Check resolution

Drop in an image and tell us how big you’re printing it.

2. Tick the checklist

Six things that catch out most print jobs.

Run through the checks

Drop in a file and tick off the list to see where you stand.

This is a quick guide, not a professional preflight — it can’t catch everything (colour profiles, overprint, hidden layers) and it doesn’t guarantee your file will print perfectly. When in doubt, ask your print shop.

What DPI actually means

Why resolution trips people up

DPI is just how many dots (pixels) land in each printed inch. A photo that looks crisp on a phone screen can come out soft on paper, because print packs far more detail into the same space. The fix isn’t magic — it’s having enough pixels for the size you’re printing.

300+ DPI

Sharp for anything held in the hand — cards, flyers, brochures.

150–299 DPI

Fine for big or far-off prints like posters and banners.

Under 150 DPI

Will likely look blurry or blocky up close. Get a bigger file.

Let the file come in print-ready

Chasing bad files is one of the biggest time-sinks in a print shop. When customers design on your store, Print-Flow 360 exports a print-ready 300 DPI CMYK PDF automatically — the artwork lands ready to print, not as a low-res screenshot you have to rescue.
