Abstract: A method of making a relief printing element in a liquid photopolymer platemaking process is described. The method comprises the steps of: (a) selectively exposing the liquid photopolymer to actinic radiation through a negative to crosslink and cure portions of the liquid photopolymer; and (b) reclaiming uncured portions of the liquid photopolymer to be reused in the platemaking process. The step of reclaiming uncured portions of the liquid photopolymer comprises (i) heating the printing element to decrease the viscosity of the uncured liquid photopolymer; and (ii) removing uncured liquid photopolymer from the surface of the relief image printing element so that recovery of uncured liquid photopolymer from the surface of the relief image printing element is enhanced.

Abstract: The invention provides a photopolymer package for use in making a hand stamp plate, the package consisting of a sachet containing a photocurable liquid polymer, the walls of the sachet being formed of material capable of being released from the cured photopolymer. Methods for the formation of the package and the hand stamp plate are also provided. The invention eliminates the requirement for the use of a backing layer in the package and thereby offers significant advantages over the prior art in terms of cost and efficiency. The invention describes how that sachet can be inserted in a holding device to expose it to UV radiation to produce the printed surface. The invention describes a novel method for spraying the sachet with a liquid to enable it to be dry post-exposed in a new type of exposure unit. It describes how this exposure unit benefits from the simplicity of the sachet concept to require no movable upper lid. This unit combines the post exposure process with the exposure process without the requirement for a water bath.

Abstract: The invention provides a stamp stock, from which a stamp can be simply manufactured, and from which non-exposed portions of a photosensitive resin are easily removed, in particular, in a manufacturing process, method of forming a stamp, and a stamp. The stamp stock comprises a seal face forming member having a photosensitive resin which changes from a liquid or gel into a solid due to light as received, and a stamp block for holding the seal face forming member. Accordingly, those portions of the photosensitive resin which receive light harden to attach to the stamp block, and those portions of the photosensitive resin which do not receive light flow out without hardening, or can be peeled off easily.

Abstract: A system and method for forming microlattice structures of large thickness. In one embodiment, a photomonomer resin is secured in a mold having a transparent bottom, the interior surface of which is coated with a mold-release agent. A substrate is placed in contact with the top surface of the photomonomer resin. The photomonomer resin is illuminated from below by one or more sources of collimated light, through a photomask, causing polymer waveguides to form, extending up to the substrate, forming a microlattice structure connected with the substrate. After a layer of microlattice structure has formed, the substrate is raised using a translation-rotation system, additional photomonomer resin is added to the mold, and the photomonomer resin is again illuminated through the photomask, to form an additional layer of microlattice structure. The process is repeated multiple times to form a stacked microlattice structure.
