
Spray (Commercial product)
This is used to apply the pretreatment onto a T-shirt. Use a spray (preferably of an electrically-operated type)
that can emit fine spray. A spray allows for easy and even coating and reduces non-uniform coating, while it
requires a special space for using it.
In addition to a spray, a pretreatment applicator (commercial product) is available that can apply the
pretreatment onto a T-shirt automatically. As required, make them available for use separately.
<CAUTION>

Fully take care of the air ventilation when you are in operation that generates mist, such as spray application.

Be sure to wear a pair of plastic gloves, a mask and protective glasses (or goggles) designed to shield against liquid splash
during the work operation.

For information on handling of the pretreatment, see the Material Safety Data Sheet issued by us.

<IMPORTANT>

If you are using an electric spray to apply the pretreatment, perform the work at a place as far as possible from the printer.
Otherwise, it may cause failure of print heads.

Heat press
It must deliver the performance through which the print range of the platen can be covered and 180°C (356°F)
can be kept for 35 seconds or more. At a fixing stage of the pretreatment, be sure to use the heat press, but not
an oven, to smoothen the surface.

Peel-off sheet
When using the heat press, place this sheet on a T-shirt so that neither inks nor pretreatment can be attached to
the press surface of the heat press. As a peel-off sheet, use a silicone-coated paper or a fluororesin sheet.
There is a tendency to bring the print result to an almost matte finish if a silicone-coated paper is used at the ink
fixation stage. There is a tendency to bring the print result to an almost bright finish if a fluororesin sheet is used
at the ink fixation stage.

Silicone foam (of open-cell structure)
It is the foamed mattress which is made of silicone that resists heat. When fixating the inks or pretreatment by
means of the heat press, use this foam to ventilate steam with ease.

Adhesive roller
Use these to remove lint from a T-shirt or debris from its surface.

T-shirt (printing medium)
100%-cotton fabric or polyester blended yarn fabric (cotton 50% or more)
<TIPS>

Although it is advisable to use a 100% cotton T-shirt, some textiles cannot necessarily guarantee good printing quality even
if they are made of 100% cotton or blended yarn. In particular, for a T-shirt made of new material, perform a printing test on
it beforehand.

Some textiles may leave noticeable imprints of the pretreatment after it is fixated. In that case, wash them away with water.

Perform a printing test beforehand. Then, the following phenomena may occur:
- The textiles may be discolored by the pretreatment and cannot be restored to the original color even if they are washed.
- A deep-colored polyester blended yarn fabric dissolves dye, which may cause the white ink to change to a slightly different
color.
- It is likely that a textile may become yellowish in color after the pretreatment is fixated.
