GT-3 Cookbook: Pretreatment with Roller



********* Preparing the Garment for Manual Pretreating with Roller *********

To apply enough pretreatment evenly and smoothly, the size is 180 mm x 50 mm, the inside diameter is 20 mm. Get a handle for your convenience, the following is a set of tools needed:

Our special roller, a tray, a small tooth brush for wiping off dusts and threads on the roller, and pretreatment bottle.

See the thickness of fine sponge. This catches the enough pretreatment and controls the amount.


Here are the steps of pretreating with our special roller.
Steps
Place the roller into pretreatment and make sure it absorbs enough pretreatment.
Draw the roller softly and remove unnecessary pretreatment.
Roll back and forth smoothly and slowly.
Roll to apply the necessary area.
Roll horizontally.
Apply pretreatment again and roll softly in both vertical and horizontal directions.

When you are not familiar with this work, there may be un-applied gaps on the T-shirt. Roll the roller all over the area several times without dropping the roller.

Weigh the T-shirt to know how much you apply pretreatment. Our option roller is very controllable.
Cure with heat press, 180 C degree (356 F degree) in 35 seconds with high pressure so that the surface will be flat.

Make sure you don't get the surface wet from the water produced by pretreatment.

Do not use conveyor oven, we need pressure to make the surface flat.
When the roller gets dirty with dust and waste threads, wipe them off with a tooth brush. Put the side of tooth brush softly on the surface and wipe off.

Keep the roller wet in pretreatment and put it on a flat place. Do not dry the pretreatment. If there are some dents on the surface then you cannot apply pretreatment evenly.
If you need higher quality, try Multi-Layer pretreatment. It takes time but works well.

When you wash the roller, squeeze it with water and dry completely. If you use it again in a wet condition, pretreatment may weakened and damage your print result.
