Print-ready vs "just exported": what printers actually mean

You exported the design at "high quality," sent it off, and the printer came back with: "This file isn't print-ready." Sometimes with a list of terms like bleed, CMYK and outlined fonts. Sometimes with no explanation at all.

"Print-ready" isn't about quality settings. It means the file is set up so the printer can produce it exactly as intended, without having to fix anything. Here's what that involves.

1. The right size

A print-ready file is built at the actual finished size of the product: a 3.5 by 2 inch business card, an 8.5 by 11 inch flyer, a 24 by 36 inch poster, a 12-inch shirt print.

A design made at the wrong proportions has to be stretched, cropped or padded, and none of those end well. If your design is 1:1 and the poster is 2:3, something has to give. Decide at the start, not at the printer.

2. Enough resolution at that size

For images and raster artwork, the standard is about 300 pixels per inch at the finished size. Large-format prints viewed from a distance (banners, signs) can often go lower; ask your printer.

Two important points:

• Resolution is about pixels per printed inch, not a setting in the export dialog. Changing "72 DPI" to "300 DPI" without adding pixels just changes a label.
• Enlarging a small image doesn't add detail. It needs a better source, or a vector version.

Vector artwork (logos, text, illustrations drawn as shapes) has no resolution limit and is always preferred for those elements.

3. Bleed and safe area

Printers can't print exactly to the edge of the paper. Instead, they print on a larger sheet and trim it down, and trimming isn't perfectly precise.

• Bleed: extend any background colour or image that touches the edge beyond the trim line, commonly by about 0.125 inch (3 mm). Then, if the cut is slightly off, there's no thin white line at the edge.
• Safe area: keep important text and logos inside the trim line by a similar margin, so nothing important gets cut off.

Many "not print-ready" rejections are simply missing bleed. Most printers provide templates that show both lines.

(Bleed matters for paper products like cards, flyers, posters and labels. Garment prints and transparent stickers usually don't need it.)

4. Fonts outlined or embedded

If your file uses a font the printer doesn't have, their software will substitute another one, and your design will change.

Print-ready files either:

• convert text to outlines (shapes), which is the safest for logos and final artwork, or
• embed the fonts in the PDF.

Keep an un-outlined copy for yourself so you can still edit the text later.

5. Colour prepared for the process

Screens display colour with light (RGB). Most paper printing uses ink (CMYK). Some colours you see on screen, especially bright blues, greens and neons, can't be reproduced in CMYK and will print duller.

• Paper printing often asks for CMYK files, or converts them for you. Converting yourself lets you see and adjust the shift first.
• Brand colours may need Pantone spot colours for accuracy.
• Garment printing (DTF, DTG) often works from RGB files; the printer's software handles conversion. Ask.

6. Images embedded, not linked

Design software often links to images rather than including them. Send the design file without those images and the printer gets missing graphics or low-resolution previews.

A PDF exported properly (for example, PDF/X from design software) embeds everything the printer needs in one file, which is why it's the most commonly requested format.

7. The format the printer asked for

Common requests:

• PDF (often PDF/X-1a or PDF/X-4) for paper and most commercial printing
• AI or EPS for signage, screen printing and cutting
• PNG with transparency for DTF, DTG and print on demand
• SVG for cutting machines

Sending a JPG when a PDF was requested usually means a round trip.

Print-ready checklist

1. Built at the finished size and proportions
2. About 300 pixels per inch at that size for images; vector for logos and text
3. Bleed added and important content inside the safe area (paper products)
4. Fonts outlined or embedded
5. Colour mode confirmed with the printer; brand colours specified
6. All images embedded
7. Exported in the format the printer requested

If a printer has sent your file back, or you want it right the first time, we prepare your artwork at the correct size and resolution, with colour set up for the print process, bleed and margins where needed, and a format your printer will accept. You'll see the price before you pay.
