What dpi should I set my artwork as?

PDF and vector artwork should be supplied at a minimum of 300dpi. This will provide the best results when printed. 

We cannot guarantee the quality of any printing using artwork lower than 300dpi.

What file formats do you accept?

We have listed below some popular file formats that we accept. 

If you don’t have artwork in any of these formats, contact us at and we can help you.


300dpi artwork will produce high-quality print results. 


720dpi won’t produce high-quality results. The format is pixelated and is low resolution. The result is that printed stickers are of poor quality.

For the best results for artwork with text, we suggest it to be at least 6pt. If possible, provide all artwork as Vector PDF. 

Do you reformat artwork?

No we wont ever reformat your artwork.

So if your artwork isn't designed to fit exactly within the dimensions you have requested then we will scale it to fit the best it possible can within the space selected, without cropping any of the artwork off.

What are CMYK and RGB and what are the differences?

CMYK is the most common digital print method. It is a colour mode made up of Cyan, Magenta, Yellow and Black (CYMK). It’s an effective print process that creates high quality finished results, however we may not be able to print in some bright colours. 

RGB is a colour mode made up of Red, Green and Blue (RGB) light. It is used in screens (those used on your computer, TV etc.) producing bright and vibrant colours. RGB is for displays and isn’t used for printing, so we use the closest CMYK equivalent. 

How much bleed should I add?

We require 5mm of background extension past the edge of the piece to make up the bleed. 

Most design packages will give you the option to add a bleed to any design. 

Some packages, such as Photoshop, don’t enable you to add a bleed. In this case, you’ll need to manually make your artwork 5mm larger on all sides of your artwork.

For example, if your sticker is 100mm x 70mm, add 5mm to each side resulting in the dimensions being 110mm x 80mm. 

Please note : if you don't add bleed or are unable to we may have to add a 2/3mm white border around your artwork when printed.
