To fixate the white ink onto the surface of fabric of a T-shirt, apply the pretreatment to it beforehand. If you are not using
white ink, you do not need to pretreat print medium.

Application of diluted
pretreatment
By means of a spray or roller, apply the diluted pretreatment onto the print medium.

Pretreatment
It is the white liquid that is needed for pretreating process for printing with white ink. If a print medium is not
coated with this agent, no color development of white ink takes place, and the whiteness becomes insufficient.
Also, no color will be produced from the color inks that are applied onto the white ink. In order to apply the
pretreatment onto a T-shirt, use a spray or roller, and use the heat press to fixate it.
<CAUTION>
Be sure to wear a pair of plastic gloves, a mask and protective glasses during the work operation.
For information on handling of the pretreatment, see the Material Safety Data Sheet issued by us.
