After introducing the topic in the previous episode and getting into the details of the criticality that may arise before the inkjet application, today’s episode focuses on the repellence phenomena that occur when a glaze or grit suspension is applied on the inks.
The different chemical nature between the solvent-based inks (non polar polymers) and all the water-based suspensions (polar) that follow one another along the glazing line is the basis of the criticality and it basically results in a incompatibility between the two elements. It's like when you try to mix oil with water.
What happens more specifically and how can you intervene to better manage the problem?
