What is flex?

Flex is a printing technique where the design is cut from a coloured foil and then pressed onto the shirt under high heat. Some flex printing features are:

Brilliant colours

The printed colours have a slight shine to them and contrast extremely well with fabric.

Longevity and durability

Tests have shown that the form and colour of the flex print barely change after 100 washes. It is made of a flexible and resilient material - even thin lines do not break.

What is writable flex?

This is a special type of flex which can be written on with a special marker (which is shipped with the product.) Otherwise, writable flex has the same characteristics as normal flex.

How do I get the best results with flex?
