In an optical disc having an RFID tag, disc control information needed for control of reproduction of the content recorded in the disc body of the optical disc is stored in the RFID tag. Thereby, even if the content recorded in the disc body is illegally copied in some way, common optical disc apparatus incapable of reading RFID tags cannot read and copy the disc control information stored in the RFID tag. Accordingly, unauthorized copying of the content recorded on the optical disc can be reliably prevented without the use of special cryptographic technology.

A temperature-altering device is thermally coupled to a dispensing device to compensate for heat dissipated into the liquid as it passes through the dispensing device during dispensing. The dispensing device may be for example, a miniature solenoid valve (microvalve), a piezoelectric printhead, or the like. According to aspects of the invention, a temperature-altering device provides or reduces heat at the point of dispensing in order to alter, control or maintain a constant temperature of the dispensed liquid. As a result, improvement is obtained in the consistency of the fluid regime of the dispensed droplet stream. The temperature-altering device may be a thermoelectric device capable of moving heat either from or to the dispensing structure, or may be a heater. This device may be used beneficially even when the dispensing is performed near room temperature and the liquid does not require heating to maintain its liquid state.

A process for printing images by means of an electrographic or electrostatic device using a toner that is cured by multiple applications of energy. The toner has energy-activated reactive components such as radiation-curable sites and reactive functional groups. An image is formed on a substrate by the toner without materially activating the reactive components. The reactive components are subsequently activated by applying a first energy source to adhere the image to the substrate by cross-linking and bonding the image permanently to the substrate, or by transferring the image to a second substrate. A second energy source is applied simultaneously with, or subsequently to, the first energy source, to promote cohesive strength of the image by cross-linking within the toner particles that form the image. The resulting image is permanently bonded to the substrate, yielding substantially enhanced image durability and fastnesses.
