(7) Move the pretreatment roller on the T-shirt in a longitudinal direction, and apply the agent evenly onto the print
range.
(8) Move the pretreatment roller on the T-shirt in a lateral direction, and apply the agent evenly onto the print range.
<TIPS>

Depending on a difference in the force applied by you to the pretreatment roller, the pretreatment may not be applied evenly
to a T-shirt. Move the pretreatment roller repeatedly on each area to apply the agent evenly onto such area.

When there is any area (gap) that fails to be coated with the pretreatment or any other area that is found to be unevenly
coated, dip the pretreatment roller in the agent again, and apply the agent evenly there.
(9) Weigh the T-shirt to check to see if the required amount of pretreatment has been applied to it.
<TIPS>

For reference guide for the amount of coating of pretreatment, refer to "6-3-3. Application of pretreatment >>P.135".

If the amount of coating is small, color reproduction of the white ink and color inks on the white ink will deteriorate.

Meanwhile, if the amount of coating is too large, it is likely that a T-shirt may harden, imprints of the pretreatment may
become noticeable or washing fastness may get worse and so on after the pretreatment is fixated.
