Abstract
A manufacturing method of printed corrugated cardboard comprising the steps of: a) providing a paper liner board (23) with an ink receiving layer; and b) inkjet printing an image with one or more pigmented aqueous inkjet inks on the ink receiving layer using piezoelectric through-flow print heads (25) having nozzles with an outer nozzle surface NS smaller than 500 μm2; wherein the one or more pigmented aqueous inkjet inks contain water in an amount of A wt % defined by: wherein the wt % is based on the total weight of the aqueous inkjet ink; wherein sqrt(NS) represents the square root of the outer nozzle surface area NS; and wherein A wt %≥40 wt %.
Claims12
A manufacturing method of printed corrugated cardboard comprising the steps of:
- a) providing a paper liner board with an ink-receiving layer;
- and
- b) inkjet printing an image with one or more pigmented aqueous inkjet inks on the ink receiving layer using piezoelectric through-flow print heads having nozzles with an outer nozzle surface area NS smaller than 500 μm2;
- wherein the one or more pigmented aqueous inkjet inks contain water in an amount of A wt % defined by Formula (I):
- 100 wt %−sqrt(NS)×3.8 wt %/μm≤A wt %≤100 wt %−sqrt(NS)×2.2 wt %/μm Formula (I)
- wherein the wt % is based on the total weight of the aqueous inkjet ink;
- wherein sqrt(NS) represents the square root of the outer nozzle surface area NS;
- wherein A wt %≥40 wt %;
- and
- wherein the dry weight of the ink-receiving layer is less than 0.8 g/m2.
