The type of artwork you supply will depend on the printing process used for that particular product. Please refer to our guide below to enable you to supply the correct artwork.

Vector files: .eps , .pdf, .ai

Suitable for all types of print. The majority of print processes and product types don’t allow for the reproduction of tints of a solid colour, any tinted areas of your artwork will need to be converted to a solid colour.

Raster(pixel) files: .png , .jpg, .tiff

Suitable only for full colour/process/transfer print, cannot be used for screen printing, debossing or engraving.

What if I don't have vector format?

Our designers can convert your logo to vector format. You will need to provide artwork in high resolution format. Please don't resave your artwork using vector file format like .eps this makes no difference.

Possible extra costs

Please note that some products will have a setup cost added to the unit costs shown above. Setup costs vary from £10 - £75 depending on the items and can be per colour.


This is one of the most popular embellishment methods, offering a very accurate reproduction of logo in detail and colour. Garments can be embroidered in different positions, providing a durable and professional finish. Embroidery is also a very cost effective method of branding for low order quantities. New logos may be subject to a one off £25 set up charge and logo application is dependent upon stitch count.


Using a specialist vinyl, we are able to re create logos and text in the form of a transfer that is applied using a heat press, permanently sealing the design to the garment. This is ideal when branding waterproof clothing to maintain the integrity of the garment and often found on high visibility workwear. With no minimum set up, basic logos can be achieved at a low price per application, even for low order quantities. For higher volume orders and more complex designs, specialist badges are made to produce a more accurate representation of the logo.


Perfect for high volume t-shirt printing, often for promotional use. This is an especially useful branding method for large logos or multiple logos both can often be incorporated in one print at a low price per garment. Pricing is based on the number of print colours and setup charge of £25 per colour will be applied for all new designs.


Tax tabbing provides a simple way of overcoming the personal tax aspect of staff clothing. Tax tabs can be manufactured and affixed to most garments. This branding method allows garments issued to employees by their employer, free of charge, to avoid the enforcement of tax as the garment is no longer classed as a “fringe benefit” to the employee that can be used outside of the work environment. This is ideal for more expensive executive wear such as suits and the financial benefits can proof vast over time. Visit the HM Revenue website for absolute clarification on the rules and regulations.


Delivery times

All delivery times are dependent upon print proof approval The average shipping time for standard packages is 3 working days but we do aim to exceed where possible.
