Abstract

Provides is a method for forming tactile images or a combination of tactile and regular images on a flexible packaging substrate comprising: depositing an ultraviolet curable phase change ink composition comprising an optional colorant and a phase change ink vehicle comprising a radiation curable monomer or prepolymer; a photoinitiator; a reactive wax; and a gellant directly onto a flexible packaging substrate or depositing the ink onto an intermediate transfer member, in an image area to form a tactile image area or a combination of tactile image area and regular image; forming the tactile image by depositing multiple layers of the ink in locations of the tactile image area or portion thereof; when an intermediate transfer member is used, transferring the deposited ink from the intermediate transfer member to the flexible packaging substrate; and curing the ink.

Description

technical field [0001] The present invention generally relates to methods of forming images on flexible substrates. In particular embodiments, the invention relates to forming or printing images on flexible substrates, such as those used in packaging and other applications, by using cured phase change inks. Background technique [0002] Inkjet printing devices are known in the art. For example, inkjet printing devices generally fall into two categories: continuous flow and drop-on-demand. In continuous stream inkjet systems, ink is ejected in a continuous stream under pressure through at least one orifice or nozzle. Disturbing the flow causes it to break up into droplets at a fixed distance from the orifice. At the point of dispersion, the droplets are charged according to a digital data signal and passed through an electrostatic field that adjusts the trajectory of each droplet to be directed towards a recirculation tank or onto a recording medium specific location. In...
