Follow this artwork checklist to avoid missing fonts, low-resolution graphics, incorrect sizes and unwanted white edges.
Start with the finished size
Create the artwork at the exact finished dimensions whenever possible. Clearly state the required width and height in millimetres and confirm whether the design is portrait or landscape.
Where artwork is supplied at a reduced scale, state the scale in the file name or order notes. Avoid changing proportions to make a design fit a different size, as this can distort symbols and text.
Add bleed
Bleed is printed artwork that extends beyond the finished cut edge. It prevents unwanted white lines if the trimming position varies slightly.
For most small and medium safety signs, add 3 mm bleed on every edge unless a different amount has been agreed. Background colours, photographs and graphics that reach the edge should extend fully into the bleed area.
Keep important content inside a safe area
Do not place essential wording, symbols or borders directly against the trim line. Keep important content at least 5 mm inside the finished edge, with more space on larger signs.
Borders require particular care because even a small trimming variation can make them appear uneven. A generous inset produces a cleaner result.
Use vector artwork where possible
Vector graphics remain sharp at any size and are ideal for pictograms, logos, lines and text. PDF, AI and EPS files can contain vector artwork, although the file format alone does not guarantee that every element is vector.
Raster images such as JPEG, PNG and TIFF are made from pixels. They should be high enough resolution at the final printed size. As a practical guide, aim for approximately 300 ppi for close-viewed small signs and at least 150 ppi for larger signs viewed from further away, unless otherwise agreed.
Prepare fonts correctly
Embed fonts in the PDF or convert final text to outlines before supplying the artwork. This prevents missing fonts or unwanted substitutions.
Keep an editable master file before outlining text, particularly where wording may need to be corrected later. Check spelling, punctuation, telephone numbers and site-specific instructions carefully.
Use CMYK colour
Prepare production artwork in CMYK where possible. Bright RGB colours seen on a screen may print differently because monitors produce colour using light while printers reproduce colour using inks.
For brand-critical colours, provide a recognised Pantone reference or an approved CMYK breakdown. Always assess colour using a calibrated proof where exact matching is essential.
Export a suitable PDF
A high-quality print PDF is normally the safest format. Export with images at suitable resolution, fonts embedded or outlined, bleed included and transparency handled by a modern PDF standard.
Do not add crop marks, registration marks or colour bars unless requested, as these can complicate automated production. Supply one artwork page per design and use clear file names that include the sign reference or wording.
Final artwork checklist
Before uploading, confirm the finished size, orientation, bleed, safe area, spelling, symbols, contact details, colour mode and image quality. Open the exported PDF and inspect it at high magnification.
Where you are uncertain, upload the artwork with a note requesting a file check. A technical check can identify obvious production issues, but responsibility for wording, legal suitability and final content remains with the customer unless a design service has been ordered.
