Isopropanol, a chemical compound and the simplest example of secondary alcohol. The compound is applied
to the cured print to test the ink adhesion, typically used in Low Fired print jobs.
MEK (Methyl Ethyl Ketone) – MEK, an organic compound. A stronger liquid, applied to High Fire prints which are not suitable for Caustic testing. Again used to test the ink adhesion.
Caustic – Caustic Test, this essentially is to simulate a prints lifetime of reuse from industrial dishwashers. Enables us to check
the durability of the ink in this situation. Used for High Fire prints.
Scratch – Scratch Tests, self explanatory. Prints are scratched to test the adhesion of the ink to the glass.
Sellotape – Whilst an older method of testing adhesion, Sellotape tests are still beneficial to ensuring the print durability. Typically used on Low Fire jobs.
