Agenda and Content

PRACTICAL BLOCKS

Textile pre-treatment: Bleaching, alkaline treatment, thermofixation.

Inkjet pre-treatment: Hydrophobic and hydrophilic treatment, treatment with water absorbing agents.

Printing: Printing with different inks on differently pre-treated textiles, printing of functional inks.

Post-treatment: Thermofixation, steaming, UV-fixation, washing and rinsing of several im¬printed textiles.

Characterisation: Measuring of surface tension and contact angle, suction velocity, bending rigidity, colour measurement, image analysis of printed substrates.

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.

Speakers and tutors

• Michaela Laupheimer, DataPhysics Instruments
• Michael Nothelfer, Caddon
• Dr Peter Oberschachtsiek, DataPhysics Instruments
• Dr Reinhold Schneider, DITF-ITCF
• Dieter Stellmach, DITF MR


ESMA Certificate

Participants will receive a certificate after attending all theoretical and practical sessions.
