METHOD AND APPARATUS FOR DRYING INKS PRINTED ON HEAT SENSITIVE ABSORBENT ARTICLE COMPONENTS

NºPublicación: EP3624747A1 25/03/2020

Solicitante:

PROCTER & GAMBLE [US]

CN_110545773_A

Resumen de: WO2018213225A1

The present disclosure relates to methods and apparatuses for printing and drying inks on substrates. Printing systems may include a metering device positioned between a printing station and a light source. During operation, the printing station deposits ink onto a substrate to define a printed region. And the light source directs infrared light onto the substrate to define an illumination zone. The printed region is advanced from the printing station to the metering device and from the metering device through the illumination zone, wherein the ink is dried with infrared light traveling from the light source, which also heats the substrate and changes the modulus of elasticity of the substrate. In turn, the metering device isolates the printing station from the change in the modulus of elasticity to help reduce phase shifts caused by changes in the modulus of elasticity resulting from heat in the substrate.
