Understanding File Formats

Before sending artwork to Printbox London, it's important to use a file format suitable for professional printing.

The most commonly accepted formats include:

• PDF – Ideal for professional printing and multi-page documents.
• JPEG/JPG – Suitable for photographs and simple artwork.
• TIFF – High-quality image format with minimal compression.
• PNG – Useful for graphics and transparent backgrounds.

For products such as business card printing London, flyer printing London, leaflet printing London, poster printing London, and brochure printing London, print-ready PDFs are highly recommended because they preserve fonts, images, and layouts accurately.

Choosing the Correct Colour Mode

One of the most common printing mistakes is submitting artwork in RGB colour mode rather than CMYK.

Professional printing uses the CMYK colour model (Cyan, Magenta, Yellow, and Black), while screens use RGB (Red, Green, Blue).

Why CMYK Matters

• Produces accurate print colours.
• Reduces unexpected colour shifts.
• Ensures consistency across printed materials.
• Improves professional print quality.

Files created in RGB often appear brighter on-screen than they do when printed. Before submitting artwork for same day printing, convert your files to CMYK whenever possible.

You can learn more about professional colour workflows through Adobe's official resources on CMYK and RGB colour management.

Checking Image Resolution

Resolution directly impacts print quality.

For professional printing, images should be prepared at:

• 300 DPI – Recommended for most print products.
• 150 DPI – Acceptable for large-format graphics viewed from a distance.
• 72 DPI – Suitable only for web and digital displays.

Low-resolution artwork often appears blurry or pixelated when printed. Whether you're ordering poster printing London, banner printing London, or document printing London, high-resolution images are essential for achieving sharp, professional results.

Quick Resolution Check

• Zoom in to 100% size.
• Check image sharpness.
• Avoid screenshots whenever possible.
• Use original image files.

Adding Bleed and Safe Margins

Bleed and margins are critical elements in print design.

What is Bleed?

Bleed refers to artwork extending beyond the final trim edge. This prevents unwanted white borders after cutting.

Standard bleed requirements:

• 3mm bleed on all sides (UK standard)
• Backgrounds and images should extend into the bleed area
• Trim marks should be included where applicable

Safe Margins

Keep important content away from edges.

• Maintain at least 5mm safe margin.
• Keep text away from trim lines.
• Avoid placing logos near the edge.

This is especially important for business card printing London, leaflet printing London, and brochure printing London.

Exporting Your File Correctly

Once your artwork is finalised, exporting correctly helps prevent production delays.

Recommended PDF Export Settings

• PDF/X-1a or PDF/X-4 format
• CMYK colour profile
• 300 DPI image resolution
• Embed fonts
• Include bleed settings
• Avoid excessive compression

Applications such as Adobe Illustrator, InDesign, Photoshop, and Canva offer export settings specifically designed for professional printing.

Proper exports ensure flawless results for online printing London, custom printing London, and urgent printing London projects.

Proofing Your Artwork

Before submitting files, carefully review every element.

Artwork Checklist

• Check spelling and grammar.
• Verify contact information.
• Confirm image quality.
• Review colours and branding.
• Ensure alignment is correct.
• Verify page order for booklets.
• Double-check dimensions.

Many costly printing mistakes occur simply because artwork was not proofread before production.

At Printbox London, we recommend reviewing files thoroughly before submitting urgent print jobs.
