1. A method for manufacturing a panel having a support and a top layer, the top layer having a printed motif and a wear layer disposed above the printed motif, the wear layer including polyvinylchloride (PVC), the top layer having an inkjet receiving layer that includes less than 10% by weight of water absorbing substances, the method comprising:
providing a printing substrate;
providing the printing substrate with the inkjet receiving layer;
digital inkjet printing the motif with a set of water-based inks;
wherein the digital inkjet printing includes one or more printing operations, each of the printing operations being dedicated to print one color;
one or more ink drying steps, wherein each of the ink drying steps is performed after performing one or more respective printing operations;
wherein the water-based ink comprises a binding agent;
wherein the binding agent of the water-based ink is vinyl chloride-vinyl acetate copolymer or polymer latexes, ether acrylates or urethane dispersion or combinations thereof; and
wherein the binding agent of the water-based ink shows a minimum film forming temperature (MFFT) below 60° C.
