How to Prepare Artwork for Print: A Beginner's Guide to Bleed, CMYK and Resolution

Artwork that looks perfect on screen can still fail once printed, because print has a few specific technical requirements a screen display doesn't — the right colour mode, enough resolution, and extra margin (bleed) around the edge — and getting these wrong is the single most common cause of disappointing or delayed print orders. Here's a practical, beginner-friendly walkthrough.

Resolution: why "looks fine on screen" isn't enough

Screens display images at a relatively low resolution compared to print, which means an image that looks sharp on a monitor can appear visibly blurry or pixelated once printed at the same physical size. For print, aim for a resolution of at least 300 DPI (dots per inch) at the final printed size — an image pulled from a website, which is typically much lower resolution, will rarely meet this standard and should be avoided in favour of an original, high-resolution source file wherever possible.

Colour mode: RGB vs CMYK

Screens display colour using RGB (red, green, blue) light; printers reproduce colour using CMYK (cyan, magenta, yellow, black) ink. These are genuinely different colour systems, and converting between them can shift how a colour appears — see our dedicated guide to RGB vs CMYK for the full explanation. As a practical starting point, design or convert your artwork to CMYK before finalising it for print, rather than submitting RGB artwork and hoping the conversion happens invisibly.

Bleed: giving your design room at the edge

Bleed is extra artwork extending beyond the final trim line, ensuring your design reaches the very edge of the finished piece cleanly after cutting, without a thin white sliver appearing at the border due to minor, normal variance in the cutting process. See our dedicated guide to what bleed is and why every print file needs it for the specifics. As a rule of thumb, extend background colours and images at least a few millimetres beyond your intended trim edge.

Safe margins: keeping important content away from the edge

Just as bleed protects the outer edge, a safe margin protects your important content (text, logos, key details) from sitting too close to where the piece will actually be trimmed. A small buffer — typically a similar distance to your bleed allowance — between your critical content and the trim line avoids text being cut off or sitting uncomfortably close to the finished edge.

File formats worth using

Vector formats (AI, EPS, PDF with vector content) scale cleanly to any size without losing quality, making them ideal for logos and line-based artwork. Raster formats (JPEG, PNG, TIFF) are resolution-dependent, fine for photography but needing careful attention to resolution at final size. A print-ready PDF, generated correctly from your design software with bleed and crop marks included, is generally the most reliable format to submit for print, since it preserves your layout, fonts and colour settings consistently.

Fonts: embedding or outlining text

If your design software doesn't embed fonts automatically within your exported file, text can shift or default to a substitute font on a different system, causing layout problems you won't see until proofing. Converting text to outlines (essentially turning text into vector shapes) before export avoids this entirely, ensuring your typography prints exactly as designed regardless of what fonts are installed on the system processing your file.

Checking your file before submitting

Before sending artwork to print, it's worth a final check: is the colour mode CMYK, does the resolution genuinely support the final print size, is bleed included, is important content within the safe margin, and are fonts embedded or outlined? Catching these issues yourself before submission avoids delays waiting for a printer to flag the same problems back to you, or worse, an unnoticed issue making it through to a finished, unsatisfactory print run.

Requesting a proof

Even with careful preparation, requesting a digital or physical proof before a full production run remains worthwhile, particularly for a first order or anything with exacting colour or layout requirements. A proof catches the kind of subtle issue — a colour that renders slightly differently than expected, a layout element that doesn't sit quite right physically — that's genuinely difficult to predict perfectly from a screen alone.

Common beginner mistakes worth avoiding

A few specific mistakes come up repeatedly for anyone preparing their first print file: designing at the wrong physical size and scaling up afterwards (which degrades resolution), forgetting to check spelling and contact details one final time after a design has gone through several revisions, and assuming a design that looks balanced on a wide monitor will look identical at actual physical size, which it often doesn't for small-format print like business cards or labels. None of these are complicated to avoid, but they're worth deliberately checking for rather than assuming a design is finished simply because it looks right at a glance on screen.

Working with templates

Many printers, including Gloss Label, provide downloadable templates for standard products, already set up with the correct size, bleed and safe margin guides built in. Using a supplied template rather than building a file from scratch removes much of the guesswork covered in this guide, since the technical setup is already correct — your job becomes simply designing within the guides provided rather than calculating bleed and margins independently for every new project.

A simple pre-submission checklist

Confirm CMYK colour mode, verify resolution at final printed size (minimum 300 DPI), include appropriate bleed, keep important content within a safe margin, embed or outline fonts, and export as a print-ready PDF where possible.
