The preparation of the black textile
Pretreatment on dark and pastel colored textiles
The garment pre-treatment is very important!
Printing to white fabric requires no pre-treatment, however printing to coloured and black fabrics
will require the use of the white ink. The pre-treatment is designed to provide a suitable coating
to take the printed inks.
Before pre-treating the fabric it should flatten is out under a heat press. Then the pre-treatment
should be applied with a suitable spray gun (we recommend Wagner W550). One thorough coat
applied to the relevant area of the fabric is enough, (remember to thoroughly clean your spray
gun when you are finished using it). Use a mohair blend roller to flatten the coating over your
textile. Apply in one direction with pressure and only once at area. This is helping for a better
application of the coating. Dry it for 30 seconds under a heat press with high pressure between
180-150ºC with heat resistant paper over it (we recommend Texjet plus Sheets). It will also press
the fabric fibres flat to give a good printing surface. Make sure the textile is completely dry
before printing.
Some garments may burn or turn yellow under high temperatures like 180ºC. In such cases take
advice on the following temperature and time diagram.
