The aim of this work was to investigate the effect of relative humidity of the ambient air on the initial print quality when printing on multifunctional office papers with the present generation of desktop inkjet printers. A range of multifunctional office papers with known behaviour were chosen to give variations in print quality parameters like optical density, colour-to-colour bleed and wicking. The papers were inkjet printed at various levels of humidity with a standardised test image. Print quality was evaluated visually and by image analysis.Some properties were clearly humidity-dependent, such as colour density and colour-to-colour bleed, but only for some printers. Other properties, like black optical density, were not effected at all. The difference between paper brands was in all cases larger than the difference between humidities.
