What Is Lascaux Screenprinting Paste
Lascaux Screenprinting Paste is a transparent, concentrated, water-based acrylic gel formulated to integrate with Lascaux acrylic colours and transform them into screen printable inks.
Visually, it is a clear gel with medium body that does not alter the tone of the colour when mixed.
It is part of the Lascaux water-based screen printing system developed as a non-toxic alternative to solvent-based processes.
Technical Function in Screen Printing
The paste performs several essential functions:
-
Adjusts viscosity so the acrylic passes correctly through the mesh
-
Acts as a retarder, extending open time
-
Reduces premature drying on the screen
-
Improves self-levelling behaviour
-
Allows longer print runs without constant water adjustment
-
Enables easy clean-up with water
Thanks to its thixotropic nature, the mixture remains stable on the screen but flows properly under squeegee pressure, producing an even and consistent ink layer.
Why Not Just Add Water?
Adding water to acrylic paint can:
Lascaux Screenprinting Paste maintains colour intensity and structural integrity while optimising print behaviour.
It is not simply a diluent, but a technical performance regulator for screen printing.
Recommended Mixing Ratio
Starting point:
Example:
500 ml paint + 500 ml paste = 1 kg ready-to-print ink.
The ratio may be adjusted depending on:
Mix thoroughly until fully homogeneous.
Compatibility
Compatible with:
Note: For textile printing, use Lascaux Textile Medium, specifically formulated for flexibility and wash resistance.

Applications
FAQs
Is this an ink by itself?
No. It is a transparent medium that converts Lascaux acrylic colours into screen printing ink.
Does it change colour intensity?
No. When used in correct proportions, it maintains colour strength and lightfastness.
Can it be used for textiles?
Not directly. For textile printing, use Lascaux Textile Medium.
Does it replace a retarder?
In many cases yes, as it extends open time and reduces screen drying.
Is it easy to clean?
Yes. It cleans with water before fully dry.
