What Is Lascaux Tusche Water-Soluble
Lascaux Tusche Water-Soluble is a water-based tusche formulated to create soluble and reactivable marks on transparent supports used for hand-made positives and photoliths. Unlike other products in the range, this tusche remains sensitive to water even after drying, allowing the drawing to be modified at different stages of the process.
This makes it a highly expressive tool for artists who treat the positive as a living drawing surface, open to corrections, shifts and controlled accidental effects.
How Tusche Water-Soluble Behaves: Reactivation and Control
Complete water solubility
The mark can be:
-
reactivated
-
softened
-
dragged
-
lightened
-
partially removed
using water, a damp brush or spraying.
Drawing correction and editing
Allows correction of lines, lightening dense areas or altering composition without fully erasing previous work.
Wear and erasing effects
Ideal for creating:
-
irregular transparencies
-
erosion effects
-
broken lines
-
organic marks
highly valued in contemporary printmaking.
Combination with other Tusches
It can be used together with:
creating contrasts between soluble and permanent areas.
Main Applications
-
Screen printing positives: reactivable drawing, corrections and graphic wear.
-
Lithography and related techniques: soluble marks and controlled wash effects.
-
Photogravure and photopolymer: tonal modulation and eroded lines.
-
Artistic offset and zincography: progressive intervention of autographic drawing.
-
Creative cyanotype: positives with soft tonal variation and water effects.
-
Experimental techniques: erasing, dragging and mixing with other liquids.
Advantages Over Other Photolith Solutions
Compared to Tusche Waterproof
Allows correction and reactivation of marks, ideal for open and experimental processes.
Compared to opaque pens
Offers greater gestural freedom and the ability to erase, move or degrade the drawing.
Compared to digital photoliths
Allows working directly on a physical support, with hands-on intervention and non-digital results.
How to Use Lascaux Tusche Water-Soluble
1. Apply onto transparent support
Recommended:
Can be applied with brush, dip pen, sponge or cloth.
2. Allow partial or complete drying
Drying time influences the degree of later reactivation.
3. Reactivate with water
Use:
-
a damp brush
-
spray bottle
-
sponge
to modify, soften or remove areas of the drawing.
4. Combine with other Tusches
Apply Tusche Waterproof to fix areas or Tusche Wash to create stable washes.
5. Expose
Carry out exposure tests according to the desired level of transparency and gradation.
