Apparatus selectively processes a substrate using radiant energy. The substrate can consist of any target material having a portion to be processed using the radiant energy and a larger portion to be unprocessed. The apparatus includes a source of radiant energy (preferably a quantum cascade laser) that has a customizable spectrum that can be configured to be specifically absorbed only by the portion to be processed, and a control system for targeting the radiant energy only at the portion to be processed. Specific examples of the use of the apparatus and method are in the technologies of heat-shrinking polyethylene film, fusing toner to paper in a laser printer, heating reaction vessels in DNA testing, and temperature profiling bottle pre-forms.

The appearance of edges in an image is improved through precise placement of subpixels within pixel cells that are located on or near edges in an image. Image data is examined to identify a "target pixel" near the edge of an object that represents the object and is adjacent to a "background pixel" that represents only background. The target pixel may represent both the object and its background or it may represent the object only. A "second pixel", adjacent to the target pixel and representing the object, is also identified. The second pixel may represent both the object and its background or it may represent the object only. The target pixel's location with respect to the second pixel is analyzed to determine the placement of a subpixel within the target pixel cell and the placement of a subpixel within the second pixel cell, such that the edge of the object is well-defined and the density of the object is preserved. A vertical smoothing process can additionally be performed to improve further the appearance of edges in the image. The technique is particularly advantageous for printing a halftoned object represented by pixels that are not saturated.

A reactive toner that is energy-activated is printed by means of an electrographic device such as a laser printer. The reactive toner is printed onto a substrate. Toner components that cross-link and bond the printed toner permanently onto the substrate, or another substrate through a transfer process, are activated by the application of energy to react after printing. Reaction of the energy-activated components may be inhibited with blocking or protecting agents. The image is permanently bonded onto the substrate when the protection provided by the protecting agents is removed by the application of energy to the printed toner. The toner may comprise energy-activated components, colorants, color enhancing polymeric materials, binder resins, internal and external additives such as waxes and charge control agents. The energy-activated components have multiple functional groups that react with active hydrogen, components that contain active hydrogen, or components that are capable of conversion to active hydrogen containing groups.

The invention provides a maze conformal cooling method and structure of a mold, and aims to solve the problem that the conventional mold cooling method cannot meet efficient and uniform cooling requirement of a complex mold. Compared with three traditional mold cooling method including a straight hole flow channel, a built-in bent pipe flow channel and a common tubular shape follow-up flow channel, the maze conformal cooling method is high in cooling efficiency and good in cooling effect. According to the structure, a hollow layer nearly parallel to the inner surface of a cavity is arranged in the position, having certain thickness distance from the cavity, in the mold, a maze type partition wall is arranged in the hollow layer, and a cooling medium flows in a channel formed by partition wall gapes in a cooling layer. The maze conformal cooling method and the structure of the mold have the advantages that the cooling state of the cooling medium in the gaps of the maze type partition wall is turbulence, and the contact area between the cooling medium and the mold is increased, so that the cooing efficiency is high, the service life of the mold is long, an injection molding process period is shortened, and the injection molding manufacturing cost is reduced. A 3-dimensional laser printing technology is adopted to directly manufacture the mold with the layered maze flow channel conformal cooling structure, components in the mold are uniform, the molding process is simple, the mold manufacturing period is short, and the mold manufacturing cost is low.

A method of laser forward transfer is disclosed. Photo energy is directed through a photon-transparent support and absorbed by an interlayer coated thereon. The energized interlayer causes the transfer of a biological material coated thereon across a gap and onto a receiving substrate.

Weatherproof sheets, suitable for conventional printing, writing, photocopying, and laser printing, are prepared by impregnantly coating a cellulosic substrate on at least one side with a durable weatherproofing composition that is water-based. The composition that is used for general-purpose weatherproof sheets comprises a styrenic acrylic copolymer, a wax, a filler for blocking resistance, a filler for tooth, and a pigment. The preparation of all-purpose weatherproof sheets, usable in photocopiers and laser printers, is made possible by substantially omitting calcium carbonate and titanium dioxide from the composition. The weatherproof sheets resist falling apart, remain legible, and can be written upon when wet. They are also non-yellowing, biodegradable and recylclable. Also, disclosed are methods for making the weatherproof sheets, as well as weatherproof sheets made by those methods.
