THEORETICAL BLOCKS
Materials: Textile substrates, dyestuffs, textile auxiliaries, thickeners, fixation of dyes.
Textile chemistry: Chemical pre-treatment of textiles, alkaline treatment, beaching, mercerization, wetting, thermofixation, finishing.
Inkjet pre-treatment: Influence of pre-treatment on printing quality, surface tension, hydrophobic and hydrophilic finishing, binders, thickeners, cationic chemicals, dye specific pre-treatment.
Inks: Ink ingredients, grinding of pigments, dispersions, particle size, viscosity and rheology, surface tension, additives, ink formulation, degassing, ink filtration, functional inks.
Printing: Inkjet printheads, printing technology and printing parameters, industrial printers, printing resolution, add-on, overprinting, digital printing of functions.
Post-treatment: Drying and fixation with heat, steaming, fixation with calendar, UV-fixation, LED-fixation, washing.
Characterisation: Surface tension and contact angle, suction velocity, bending rigidity, colour measurement, contour sharpness/printing quality, fastness properties.
Colour management and calibration: Colour theory, colour calibration theory, colour space, colour correction, calibration dessin, automated colour measurement, colour management software.
All theory blocks will have a logical continuation during lab-based practice sessions. The sessions will be scheduled and announced as soon as the regulations allow on-site gatherings again.

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
