We print all labels using our DTG technology.
When providing artwork we state for the best results that the image is 300dpi in PNG format.
The maximum printing size for a label is 6 x 6cm
The details we recommend you include in your label are:
Fabric (i.e. 100% cotton)
Care instructions (Wash at 30, inside out. Do not tumble dry, do not iron directly over the print)
Here's an example.
