Crack Print Rubber
Crack print rubber brings a crackle effect into rubber print. A base layer of rubber ink is printed and left to partly dry, then a top layer, often in another colour, goes over it. The top layer does not bond to the drying rubber, so it cracks and leaves a distressed print with a rubberised texture.
VISUAL EFFECTS
Cracked rubber print with a second colour showing through
HAND-FEEL
Rubbery, textured surface broken by cracks
BENEFITS
The cracked rubber surface gives a distressed, textured look, and ink colour and drying time can be adjusted to control the crack pattern.
LIMITATIONS
Crack patterns vary with drying conditions and ink properties, so they are tested before production. The cracks can shorten the life of the print unless it is sealed or finished.
PROCESS
[01] Printing
Print a base layer of rubber ink as the foundation for the cracks.
[02] Drying
Let the rubber ink partly dry; how far it dries sets the size and spread of the cracks.
[03] Second Layer Application
Print a top layer of ink, often in a different colour, over the partly dried rubber.
[04] Drying
Let the whole print dry fully.
[05] Sealing
Optionally, apply a clear sealant or finishing coat to protect the cracked print.
TO CONSIDER
Substrate Compatibility
Make sure the fabric is compatible with rubber ink and can withstand the cracking process.
Experimentation
Test on sample materials to see how drying time, layer thickness and the rubber ink affect the cracking.
Top Layer Selection
Choose the top layer carefully, as different inks produce different cracking patterns.
Sealant Compatibility
If a sealant or finishing coat is used, make sure it is compatible with the rubber ink, to preserve the print and prevent further cracking.
Application Conditions
Temperature and humidity can influence the cracking pattern and the overall print quality.
