The present invention relates to a curable jettable fluid for making a flexographic printing master characterized in that the jettable fluid has a viscosity measured at jetting temperature of less than 15 mPa&#xb7;s and comprises at least 50 wt. % of a mixture of a cyclic monofunctional (meth)acrylate monomer, a monofunctional urethane acrylate oligomer and a difunctional (meth)acrylate monomer.

Curable jettable fluid for making a flexographic printing master

A method for making a flexographic printing master includes the steps of providing a flexographic printing support; providing an inkjet printing device; applying a mesa relief on the flexographic printing support with the inkjet printing device; and applying an image relief with the inkjet printing device on the mesa relief. A method for making a flexographic printing master includes the imaging apparatus.

Imaging apparatus and method for making flexographic printing masters

A method of preparing a flexographic printing master including an optional elastomeric floor, an optional mesa relief, and an image relief are applied in this order on a flexographic printing support includes applying and curing fluid droplets thereby building up a plurality of layers of fluid on top of each other, wherein each fluid droplet applied is at least partially cured before an adjacent fluid droplet is subsequently applied, with the exception that a fluid droplet applied during building up at least one layer of fluid is not cured before an adjacent fluid droplet of the same layer is subsequently applied.

Method of preparing a flexographic printing master

A method for making a flexographic printing master includes the steps of providing a flexographic printing support; applying image-wise on the flexographic printing support subsequent layers of radiation curable liquid by an inkjet printing device whereby one or more applied layers are immobilized using a curing device before one or more subsequent layers are applied, such that a relief with a top hat profile is obtained; and grinding the relief so that the height DT of a top hat segment is reduced. An imaging apparatus includes structure to perform the above method.
