4. Printing Directly from Applications

4-6. Printing

Ensure there is adequate space left for safe working. The Platen moves forward while operating.
Do not handle the platen while printing. If your hand gets caught between the platen or the T-shirt tray and the
covers, injury may result.
Do not move the Platen by hand.
The Printer may be mechanically and electrically damaged.
Do not put your hands inside the covers while the printer's power is turned on, otherwise your hands may touch
against moving parts and this may result in injury.
Take care not to let the liquids: Ink, Wash Liquid, Maintenance Solution, Pretreatment or waste liquid come into
contact with your eyes or onto your skin, otherwise inflammation can result. In case of contact with eyes, do not
rub but immediately rinse the eyes with water.
Furthermore, do not drink the liquids: Ink, Wash Liquid, Maintenance Solution, Pretreatment or waste liquid under
any circumstances, as they can cause vomiting and diarrhea.
Keep the liquids out of the reach of children.

4-6-1. Applying the Pretreatment

Pretreatment must be applied on a T-shirts to keep the White ink on the surface of a T-shirt. Wear gloves to keep
Pretreatment from the skin.
<Note>
Use a heat press and "thin and flat" glass cloth sheet or fluorine coated sheet (Teflon Sheet) to cure the Pretreatment.
The surface must be as flat as possible in curing. If you use an oven, the fibers may not lay down flat causing low print
quality.
Place glass cloth sheet or fluorine coated sheet (Teflon Sheet) to cover the pressed surface so that the T-shirt can be flat
and even.
Water drops on the Pretreatment-cured surface turn stains, because the white ink can sink into the T-shirt fibers. Do not
wet the cured surface. Do not leave a Pretreatment-cured T-shirt in a humid space.
Be aware of the temperature of the heat press in curing the Pretreatment. Temperature easily drops by continual curing.
If the temperature is low, the Pretreatment can not make ink barrier on the surface of the T-shirt and the White ink may
easily sink into the fibers and can not produce enough white.
Better to use an Urethane mat (continuous foam) to release more steam while curing.
If CMYK inks are printed on a Pre-treatment applied T-shirt, ink may washed off. Do not apply Pretreatment when you
print without using White ink.
Pretreatment on some T-shirts may be seen easier after applied and cured. Wash lightly with water. Some dyes may be
decolorized by Pretreatment, we recommend you test the garment before printing.
Pretreatment mist may spread out when you use a spray and/or pretreatment applicator. Ventilate your room in operation.
Wear a face mask or goggles as necessary.
