A cooling module, which is securable to one or more thermal transfer members for an LED curing apparatus, wherein the cooling module comprises a first finned heat sink and a second finned heat sink; wherein the first finned heat sink is removably securable to the second finned heat sink to provide at least one aperture therebetween, wherein each of a plurality of fins protrude from the first finned heat sink and from the second finned heat sink and each fin is substantially perpendicular to the length of the or each aperture, wherein the first finned heat sink is removably secured proximal to the second finned heat sink by at least one locking member, and wherein the or each locking member is inserted such that its length is parallel to the length of the or each aperture.

An LED curing apparatus comprising at least one LED radiation source mounted on an LED mount; a housing comprising at least one air inlet; at least one finned heat sink; and at least one air passage through the housing from the or each air inlet through the or each finned heat sink to at least one air outlet; wherein the housing comprises an inlet cavity below the or each finned heat sink and an outlet cavity above the or each finned heat sink to maintain a higher air pressure below the or each finned heat sink and a lower air pressure above the or each finned heat sink.

A curing station for curing printing ink of a direct print on containers, comprising a conveyor for conveying the containers preferably in container holders, and further comprising at least one UV light unit for curing the printing ink, characterized in that the at least one UV light unit comprises a 2D arrangement of UV LEDs for generating a UV light field for curing the printing ink.

Based on evaporation of fountain solution from a rotating blanket cylinder to create an image that may be inked and printed, a digitally addressable heater array at or just below the blanket surface evaporates deposited fountain solution and forms a fountain solution latent image on the surface. The heater array has controllable heating elements (e.g., field effect transistors, thin film transistors) that provide a transient heat pattern on the surface to evaporate the fountain solution. Heat is generated by current flow in the heating elements, and power developed by the heating circuit is the product of source-drain voltage and current in the channel. Current may be supplied along data lines by an external voltage controlled by digital electronics to provide the desired heat at heating elements addressed by a specific gate line. The heater array may include a current return line that may be a 2-dimensional mesh.

The disclosure relates to methods of manufacturing surface materials for construction or manufacturing use and the surface materials produced by such methods. Substrate materials, such as synthetic or engineered stone or fiber-reinforced resinous panels, can be formed in conventional ways such as casting, molding, or pressing. Layers are printed onto substrate materials to form textures, which may include inks to selectively color the printed texture, thereby enabling a wide variety of high-resolution appearances. A clear, protective topcoat is then applied to the surface materials and cured to provide a finished material.

The present invention relates to a method for controlling the curing degree of at least one at least partially cured ink and/or varnish printed on a substrate, which comprises cutting at least one sample from an area of the printed substrate, placing and incubating it in a solvent, in which at least one of the at least one extractable compound is soluble, and removing it from the solvent to obtain a solvent extract; quantitatively measuring a spectroscopic characteristic of the solvent extract; comparing the measured numeric value of the spectroscopic characteristic with a reference value of the spectroscopic characteristic for the same area of the printed substrate; and outputting a result, wherein the reference value of the spectroscopic characteristic for the same area of the printed substrate has been obtained by the use of an empirical model.

A method produces a printed product. The method includes transferring a first Fluid onto at least one section of printing stock, applying a second fluid, having a dewetting effect on the first fluid, onto a form configured as a relief printing form or embossing form, and transferring the second fluid to at least some points of the section. In this manner printed products of high quality can be produced.
