What Is Lascaux Textile Medium
Lascaux Textile Medium is a transparent water-based acrylic medium formulated to transform Lascaux acrylic paints into textile printing ink.
Its main function is to modify the acrylic film so that it becomes:
It is not a simple diluent, but a structural modifier of the acrylic polymer.
How It Works in Textile Screen Printing
When mixed 1:1 with Lascaux acrylic paint:
-
Adjusts viscosity for correct mesh passage
-
Adds flexibility to the dried ink film
-
Improves adhesion to cotton and natural fibres
-
Maintains colour intensity
-
Reduces cracking and stiffness
Example:
500 ml paint + 500 ml medium = 1 kg ready-to-print textile ink.
Difference from Using Acrylic Alone
Pure acrylic may:
Lascaux Textile Medium modifies the paint structure to improve durability and flexibility.
Does It Require Heat Setting?
According to the manufacturer, when mixed correctly, additional heat fixation is not strictly required.
However, in professional practice, light heat setting may improve wash resistance in demanding fabrics or intensive washing conditions.
Always perform tests before production.
