
Pretreatment roller (option)
This is used to apply the pretreatment onto a T-shirt. It is advisable to use such a handgrip for the roller that is
resistant to rust formation.
<NOTE>

Separately provide a tray (container for dilution), handle (handgrip for roller), agent-coating table and weighing instrument
for amount of coating.

Spray (commercially available item)
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. As compared with a roller, 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 application device (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 work on 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 to 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.
