Transfer and sublimation printing on masks: what to do if halos appear around the design

Prensas Térmicas

I’ve recently started creating decorated objects using sublimation printing, however, often when I print lettering there’s a halo around it.

If I reduce the temperature of the heat press, the print becomes discoloured, but if I increase it, the colours are as they should be, but halos appear around the design.



Red halos are the result of the ink partially propagating along the fibres of the fabric when heated, spreading and forming a halo.

I’m not sure if there’s anything you can do to prevent it, because masks are made of material that’s very porous and thin.

You could try increasing the pressure of the heat press, this would leave less space between the transfer paper and the fabric.

For sure, the heat press temperature needs to be 200°C to enable the ink to sublimate.

The transfer time should be as short as possible, just long enough for the ink to heat up and be transferred.
