iPrint Know How

What colour mode should my artwork be supplied in?
All artwork must be supplied in CMYK colour mode, not RGB.

RGB is used for screens and will convert to CMYK for print, which may cause colour shifts. To ensure accurate results, convert your artwork to CMYK before submitting.

Which colour profile should I use?
We recommend using:

• Coated paper: FOGRA39 / ISO Coated v2

• Uncoated paper: FOGRA29 / ISO Uncoated

If you are unsure, please contact us before exporting your file.

Will colours match exactly to my screen?
Printed colours will differ slightly from what you see on screen due to monitor calibration and colour space differences. For brand-critical work, we recommend supplying Pantone references, RALs, hard copy samples you’ve had previously or requesting a printed proof.

Do I need to include bleed?
Yes. All artwork must include 5mm bleed on all sides.

This means any background colours, images, or design elements that run to the edge of the page must extend 5mm beyond the trim size.

What is a safe zone?
Keep all important text and logos at least 5mm – 10mm inside the trim edge to avoid risk of trimming variation.

How should I supply multi-page artwork?

Please supply multi-page documents as a single PDF in page order, set up as individual pages (not spreads), unless specifically requested. We will

Include:

• Correct page size

• 3mm bleed on all pages

• Consistent margins

• Crop Marks

For stitched booklets, ensure page counts are divisible by 4.

Does paper choice affect artwork?
Yes. Different materials affect colour and finish:

• Uncoated papers appear softer and slightly less vibrant.

• Coated papers produce sharper detail and more vibrant colours.

• Recycled stocks may slightly alter colour tone.

• Large format materials may require higher resolution artwork.

If you need guidance selecting the right stock for your design, we’re happy to advise.

What is the minimum readable text size?
As a general guide:

• Standard print: Minimum 6pt

• Reversed (white on colour): Minimum 7–8pt

• Large format (viewed from distance): Text size should scale accordingly

Avoid very thin fonts below 7pt, as they may not reproduce clearly.

How can I make my artwork more accessible?

We recommend:

• Strong colour contrast between text and background

• Minimum 10–12pt body text where possible

• Avoiding long passages in all caps

• Not relying on colour alone to convey meaning

• Clear, legible font choices

If your materials need to meet specific accessibility standards, please let us know.

What size should QR codes be?
Minimum recommended size:

• 20 x 20mm for standard print

• Larger for posters or outdoor materials

Ensure strong contrast (black on white preferred).

Do I need to test my QR code?
Yes. Always test QR codes before submitting artwork. We can generate static QR codes for you. Ensure your QR code does not require a subscription to stay active.

Can I include clickable links?
Clickable links only function in digital PDFs. For print, ensure URLs are short and easy to type.

What image resolution is required?

• Standard print: 300ppi at final size

• Large format: minimum 150ppi at final size

Low-resolution images (72ppi web images) will appear pixelated in print.

How can I check image resolution?
Check the effective resolution in your design software at 100% scale.

What is the difference between vector and raster artwork?

• Vector graphics (logos, icons, text) are scalable without losing quality.

• Raster images (photographs) are resolution dependent.

We strongly recommend supplying logos as vector files (AI, EPS, or outlined PDF) to ensure sharp reproduction at any size.
