For whom
The “Digital Printing on Textiles” course is open to everyone who wants to learn about the technology behind digital textile printing and specific application requirements. We welcome printers, print service providers, textile manufacturers, suppliers, developers, chemists and all those impacted by the shift to digital production processes. Participants will receive insights in the procedure of inkjet printing on textile materials and accompanying topics such as textile chemistry and pre-treatment, ink formulation, curing techniques, colour management and characterisation of textile materials and printing quality. The participants will be able to decide if and to what extent inkjet printing technologies can be applied in their own production. Participants do not need to have any special previous knowledge.
