Abstract [en]

Research has been carried out to study the factors that affect ink setting, with particular focus on the effects of coating polarity and the printing pressure in flexographic printing. Different coating layers were prepared on non-porous polyester films. The coating colours were based on calcium carbonates of different particle sizes, lattices of different polarities and a carboxymethyl cellulose (CMC) thickener. Two latex films were prepared to characterise the surface tension properties through contact angle measurements, which were repeated several times for each latex film and testing fluid. The coating layers were printed in a laboratory printing press under different printing pressures using a water-based flexographic ink. Results showed different print densities for a given amount of ink transferred on the different substrates, with the latex character rather than the pore size of the substrates affecting the print density. Compared with the less polar substrate, the more polar substrate resulted in a higher print density. A non-linear relationship between physical dot enlargement and printing pressure was visualised, resulting from increasing printing form deformation. A mathematical model for printing plate deformation has been proposed that takes into account elastic deformations. It was found that the diameter of the printed halftone dot was larger in the print direction than in the cross print direction. (7 fig, 6 tab, 17 ref)
