The present invention is directed to a method for single pass printing on an absorbent non-white substrate. The method comprises: (a) applying a primer composition to one or more selected surfaces of an absorbent non-white substrate to form a primer layer to seal the selected surfaces of the substrate, (b) drying the primer layer, (c) printing a white ink on the primer layer, and (d) drying or curing the white ink. The present invention also relates to low odor radiation curable white ink compositions. The composition comprises 10-40% w/w of 4-hydrobutylacrylate, 0.5-10% of a urethane (meth)acrylate oligomer, 10-55% of diacrylates, one or more photoinitiators, one or more additives, and one or more white pigments. The composition excludes many monofunctional monomers that have distinct odor and are commonly used in an ink jet composition.
