Design guidelines
Use CMYK as the colour mode.

Prepare your files using CMYK as the colour mode, not RGB. Use colourmode FOGRA39 (ISO Coated v2). If you are unsure of the colour mode of your file, don't worry we can always convert this for you. Keep in mind this can cause the colours to differ from the original file.

Resolution of at least 300 dpi.

Make sure the resolution of the images and graphics in your artwork are at least 300 dpi.

Fonts should be at least 6pt.

Fonts should be at least 6 pt.

Make sure the ink coverage isn't higher than 300%.

Force Colour Images to CMYK with a 260% ink limit (in Photoshop > Convert Colour Profile > Photoshop 5 Default CMYK). Make sure the ink coverage isn't higher than 300%.

Save your files in uneditable, print-ready file formats.

Save your files in uneditable, print-ready file formats (PDF (1.4 or higher), TIFF, EPS, JPG). Deliver your files in one layer: the background layer.

Convert fonts to outlines or embed all the fonts.

Make sure you convert fonts to outlines or embed all the fonts when saving it to PDF.

Use the right values for full colour black.

Use Rich Black (C:63% M:52% Y:51% K:100%) for larger areas and text to get a deep black colour. Do not use this value for text smaller than 15 pt or plain text. This can only be used in full colour printing. For designing black smaller texts use 100% black.

Check line thickness.

Lines should be at least 0.25 pt. Negative lines should be at least 0.5 pt.

Check your artwork on overprint.

Make sure no elements in your artwork are set on overprint unless you want this effect in your design. You can read more about overprint in our Help Centre.

Keep in mind the safety margins.

Keep all important text and images within the safety margins which are displayed in the templates.
