Demystifying Print Bleeds and Margins: The ‘Get It Right the First Time’ Checklist

The agency submitted the artwork at 10am. By 2pm, the client was calling to find out why their brochures hadn’t shipped. The answer: the file was RGB, had no bleed, and the logo was a low-resolution JPEG. Everything had to be resent. The job missed the cut-off. The event was the next morning. It’s a story that plays out at least twice a week across Singapore print shops — and every single time, it was entirely avoidable.

Artwork file errors are the single most common cause of print delays in Singapore. They’re not caused by printer incompetence — they’re caused by designers and marketers who learned digital production workflows and were never taught the additional steps that print requires. The rules aren’t complex. Once you know them, they take five minutes to apply. Not knowing them costs hours — sometimes days.

This checklist covers every critical artwork requirement for print production. Run through it before submitting any file to any printer. It applies to flyers, name cards, banners, posters — everything.

What Is Bleed and Why Does It Matter?

Bleed is the extension of your artwork beyond the final trim edge of the printed piece. When a printer cuts a stack of sheets to size, the cut position isn’t perfectly consistent across every sheet — there’s a tolerance of approximately 1–2mm. Without bleed, this tolerance creates white edges where the background colour or image doesn’t quite reach the trim line.

The standard bleed requirement for Singapore print production is 3mm on all four edges. If your final document is 148mm × 210mm (A5), your artwork canvas should be 154mm × 216mm — with the design elements extending to the full canvas size on any edges that should be full-bleed.

For large-format printing — roll-up banners and posters — the bleed requirement is typically 5mm due to the larger sheet movement during cutting. Check the specific product template on ExpressPrint’s product page for exact dimensions.

The 5mm Safe Zone: Keeping Your Content Out of the Danger Area

While bleed extends the artwork outward beyond the trim, the safe zone pulls critical content inward from the trim edge. Any text, logo, or design element you want to guarantee survives the cutting process should be kept at least 5mm inside the trim line.

This matters most for elements near the edge of the design: contact details on a business card, the address line on an A5 flyer, the logo on a poster positioned close to the bottom edge. If any of these sit within 5mm of the trim, they risk being partially cut — regardless of how careful the operator is.

CMYK vs RGB: The Colour Mode Rule

Digital screens display colour using RGB (Red, Green, Blue) — an additive colour model where colours are created by combining light. Commercial printing uses CMYK (Cyan, Magenta, Yellow, Key/Black) — a subtractive model where colours are created by combining inks.

These two colour models do not map perfectly to each other. Certain RGB colours — particularly vibrant electric blues, bright greens, and fluorescent shades — cannot be reproduced in CMYK. When an RGB file is sent to a CMYK press, the print software converts the colours using its own interpretation, which often results in muted, shifted, or washed-out output.

The rule is simple: set your document to CMYK before you design. Converting from RGB to CMYK at the end still results in shifted colours — because the design was created in an RGB gamut that CMYK can’t fully reproduce. Starting in CMYK means what you see is closer to what you get.

Resolution: The DPI Rules by Format

Resolution requirements differ significantly between small-format and large-format printing:

• Business cards, flyers, brochures, posters (A3 and below): 300 DPI minimum at actual print size. Images at 150 DPI will print visibly soft. Images at 72 DPI (screen resolution) will print blurry.
• Large format (banners, posters A2 and above): 100–150 DPI at actual print size is acceptable. Large format is viewed from distance; the apparent resolution at viewing distance is equivalent to a 300 DPI small-format print. Do NOT try to print a 300 DPI file at A0 size — the file will be enormous and slow to process.
• Logos: Always use vector format (AI, EPS, SVG). A vector logo prints sharply at any size, from a 9mm business card logo to a 6-metre banner. A rasterised JPG logo will pixelate when enlarged and cannot be recovered.

The Pre-Flight Checklist

Before submitting any file to ExpressPrint, run through this checklist:

• ☐ File format: PDF (preferred), AI, or EPS — not JPG, PNG, or Word
• ☐ Colour mode: CMYK (not RGB)
• ☐ Bleed: 3mm on all edges (5mm for large format)
• ☐ Safe zone: All critical content 5mm inside trim line
• ☐ Resolution: 300 DPI for small format; 100–150 DPI for large format
• ☐ Fonts: Outlined or embedded (not live text)
• ☐ Images: Embedded (not linked)
• ☐ Spot colours: Converted to CMYK unless requesting spot colour printing
