Bases are a layer of white ink that lies underneath a design to help colours stand out when printed onto dark coloured shirts. Without this base, the colours will look muted when printed. The base is hidden as it is made slightly smaller than the design itself. See images below for a visual to show how this impacts a design.
Without a base underneath the colours, the garment will show through leaving the print looking dull and muddy.
With a white base underneath the colours, the print will be much more bright and vibrant.
As you can see, the white base isn’t visible as it’s printed underneath the colours.
In some circumstances your order may need an additional Poly Base. When printing onto polyester garments the dyes in the fabric can cause the ink colours to sublimate. For example, a white print on a red polyester garment will sublimate and turn pink in colour, and a white print on a black polyester garment will sublimate to a grey colour. The Poly Base blocks this reaction from happening so your print colours remain true to colour, and stay bright and vibrant on polyester fabrics.
