Laser^® 4000 PT Pre-treatment Chemical is a solution used for direct to Garments (DTG) application, tailored for dark-colour cotton t-shirts, ensuring deep & brighter shades with good printing quality

ADVANTAGES:-

Proper application of the pre-treatment solution is crucial to achieve optimal white, opacity and ink adhesion on fabric, whether dark or light-coloured cotton.

Application of Laser^® 4000 PT Pre-Treatment Chemical:-

It can be applied manually using a handheld sprayer or mechanically though an automatic pre-treatment unit. Now a days many DTG Printers are using automated spraying machines, which provides consistency and repeatability in pre-treatment application, although manual application using a handheld sprayer is also effective. Instructions for manual application are outlined below. For automatic pre-treatment machines, consult the vendor’s usage Instructions for safety and proper use.

For both manual & automatic application method, the quantity could be required approx. 0.0016 to 0.020 grams/ square centimeter.

Some machines have special setting of volume to be used, for that purpose it is recommended to follow manufacture’s instructions to determine the correct amount of pre-treatment chemical requirement.

Drying after Pre-Treatment application:-

It is basically required to remove excess moisture & stability of fabric.
Achieving an ideal condition for drying minimizes time, temperature, and pressure to maintain print quality. Avoid over-drying, as it can reduce wash fastness.
It can be dried using either a heat press or a heat tunnel after application. For the best result, use thin, disposable parchment paper, non-stick papers, or non-stick polymer sheets. These materials offer uniform drying and better volatile evaporation. They should be used once per garment and then discarded. If not available, alternative non-stick paper can be used.
