A thin film video device is mounted onto a card stock and incorporated into a card, such as a greeting card. The thin film video device comprises a thin film video display coupled to a computer chip and a speaker. The thin film video device is powered by a local power source such as a small battery. The thin film video device is activated when the user unfolds the card, at which time an audiovisual message is displayed on the thin film video display and through the speaker.

Pressure-responsive particles include pressure-responsive base particles and first inorganic oxide particles, in which the pressure-responsive base particles contain a styrene-based resin which contains styrene and other vinyl monomers as polymerization components and a (meth)acrylic acid ester-based resin which contains at least two kinds of (meth)acrylic acid esters as polymerization components and in which a mass ratio of the (meth)acrylic acid esters to all polymerization components is 90% by mass or higher, Db/Da which is a ratio of a number average particle diameter Db of the first inorganic oxide particles to a number average particle diameter Da of the pressure-responsive base particles is 0.05 or higher and 0.25 or lower, the pressure-responsive particles have at least two glass transition temperatures, and a difference between a lowest glass transition temperature and a highest glass transition temperature is 30° C. or higher.

This application is related to a greeting card that is conducive to automated printing, as well as methods and systems for printing on the greeting card. For example, the greeting card can include a three-dimensional (3D) card element that is containable, when the card is being printed, between a first panel of the greeting card and a protective panel of the greeting card. In addition, the greeting card can include a second panel for receiving a printed graphic (e.g., text, letters, numbers, pictures, symbols, etc.).

A security-enhanced document including a substrate, variable indica applied to an area of a first side of the substrate, a scratch-off-coating applied over the variable indicia to maintain the variable indicia unreadable until the scratch-off-coating is removed by being scratched off, and digital imaging applied to an area of a reverse side of the substrate from the variable indicia, wherein the digital imaging applied to the area of the reverse side of the substrate includes the same materials as the variable indicia, is uniformly spread over the area of the reverse side of the substrate, and such that the digital imaging overlaps at least 50% of the variable indica applied to the area of the first side of the substrate, such that the variable indicia exhibits an insufficient signal-to-noise ratio relative to the signal-to-noise ratio of the digital imaging on the reverse side of the substrate so that the variable indicia cannot be discerned so long as the scratch-off-coating remains intact.

The invention comprises an apparatus and method of use thereof for processing a machine produced emulated handwritten document prepared on a marking surface, comprising the steps of: receiving a print job order; digitally generating a reference image of the print job order; machine plotting with a plotting pen and a downward force of one-half to forty ounces applied to said plotting pen an indentation trail to form input text on the marking surface; digitally imaging the input text on the marking surface to form an actual image; and in a quality control step, digitally comparing the reference image to the actual image prior to insertion of the print job order into an envelope.

Sleeve systems including a sleeve and a tab. The sleeve systems function to protect a trading card. The sleeve is complementarily configured with the trading card to receive the trading card. The tab is coupled to the sleeve. In some examples, the sleeve system includes a shell complementarily configured with the sleeve to receive the sleeve.

A system comprising modules. Each module includes: a presentation system including one or more of a speaker and a video screen; and a port. In use, if the presentation system includes the speaker, the system produces sounds derived from data obtained via the port. If the presentation system includes the screen, the system displays images derived from data obtained via the port. The module can also include connectors and the system can also include actuators. Each actuator, in use, can be coupled without soldering to a connector, and the presentation system of each module can operate in response to the actuator or actuators coupled to said each module. The system can also include data storage devices, each adapted to be releasably coupled to a respective port, and the port can be selected from: microchip socket and USB port. The system can be used as part of a method.

Disclosed herein is an electrostatic ink composition comprising a component selected from a fatty acid ester having a plurality of hydroxyl substituents and a fatty acid amide having a plurality of hydroxyl substituents. Also described herein are scratch-off structures and methods for producing them.
