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.


Pure water
It refers to distilled water, purified water, etc. which is used to dilute the pretreatment with it.
Put the pretreatment into a polypropylene container or the like, and dilute it with
pure water.
By means of a spray or roller, apply the diluted pretreatment onto the print medium.
Fixate the pretreatment by using the heat press to apply heat and pressure onto
the print medium.
