“That’s a picture, not a print file”: How to turn an AI image into a print file

Why printers ask for this

Print sharpness comes down to pixels divided by print size. OpenAI lists 1024 × 1536 pixels as a standard portrait size, which is about 120 ppi on a letter-size flyer, and printers usually ask for 300 ppi. Sizes vary by tool and keep changing, so check your own file rather than assuming.

The bigger problem is that everything is one layer of pixels. The words are painted in, so they can’t be edited and small type prints soft. AI tools can also misspell words in ways that are easy to miss. A logo is pixels too, and a QR code may only be a drawing of one, which looks right and scans to nothing.

The image also won’t match the job. AI tools make their own shapes rather than your trim size, nothing runs past the edge for bleed, and the color is usually RGB. A 3D picture of a box is further off still, because a printer needs flat artwork on the dieline.

How to turn an AI image into a print file

1. Check the pixels first. Divide the image’s width in pixels by the print width in inches, then aim for 300. A letter flyer with 0.125 in bleed needs about 2625 × 3375 pixels, and a business card with bleed about 1125 × 675. The free DPI calculator does the math.
2. If it’s short and the image is a photo or illustration with no small text, enlarge it. In Photoshop: Image → Image Size, turn Resample on, choose Preserve Details 2.0, enter the size at 300 ppi, then check it at 100%. This estimates detail rather than recovering it, so it only goes so far.
3. Set up a new document at the trim size with 0.125 in (3 mm) bleed in Illustrator, InDesign or Canva, and place the image so it runs past the edge on every side. If it stops short, extend or crop it before going further.
4. Remove the text from the picture and type every word again as real text. Proofread it against what you meant to say, not against the image, because AI spelling errors are easy to read past.
5. Replace the logo with your original vector file. If you don’t have one, redraw it. Image Trace can work on simple shapes, but check the result closely.
6. Delete any QR code in the image and make a real one with a QR code generator, as a vector if you can. Test it with a phone on a printed copy, at the right size.
7. Export a print-ready PDF, in CMYK if your printer asks for it, then run it through the free print-ready checker. Ask for a proof if the job is large.
