ABSTRACT:
A radiation curable ink-jet printing process is disclosed, exhibiting consistent image quality on a wide variety of different ink-receivers. The ink-jet printing process includes the steps of:a) providing an ink-receiver;b) providing a surface layer on at least a portion of the ink-receiver with a dotsize control fluid;c) jetting at least one radiation curable ink-jet ink droplet to the surface layer on the ink-receiver;characterized in that the dotsize control fluid contains a surfactant, a film forming polymeric resin and an inorganic filler, wherein the ratio P/F is greater than 3.0, with P being the weight % of film forming polymeric resin and F being the weight % of inorganic filler, both based on the total weight of the dotsize control fluid, and the surfactant is present in the surface layer in the range of 0.1 to 20% by weight based on the total dry weight of the surface layer.
