The present invention relates to a mixed ink mixed with a far-infrared-emitting material, a method for preparing the mixed ink, and a printed matter on which the mixed ink is printed, wherein the mixed ink is a printing ink used in a printing process for a printed matter and the mixed ink is prepared by mixing a pigment mixture with a powder type far-infrared-emitting material. Therefore, a mixed ink, which is to be printed on an object, is mixed with a far-infrared-emitting material to maintain a high far-infrared emissivity of 0.88 or greater, so that 60% or more of various noxious gases, which are generated from the printed matter, can be deodorized to allow a user to use the printed matter without repulsion; about 90% or more of staphylococci and pneumococci can be reduced to maintain cleanliness; and the contamination and pathogen transmission due to the use of the printed matter can be prevented in advance.

Disclosed embodiments may relate to a time-dependent color-changing label for a product. The label may include a first layer comprising a plurality of particles, the particles comprising a time dependent color-changing material that changes color after a predetermined time period, the predetermined time period being greater than one month. The label may also include an attachment structure attaching the first layer to the product. In certain embodiments, the first layer may include a polymer, and the particles may include glass microspheres containing the time-dependent color changing material. The particles may be embedded in the polymer.

The following invention represents a postcard, comprising a laminar body adapted to be decorated externally with at least one predefined illustration. Said body has an opening for access to an internal recess, said opening is normally closed by a removable cover. The recess accommodates at least one seed and a substrate, and that at least one seed is arranged on the top of the substrate and directed toward said opening, for the sprouting of a plant after the removal of the cover and the addition of water into the recess. The seed is normally being retained on the top of said substrate by a laminar containment element, which is made of water-soluble material and is interposed between the substrate and the cover.

A simulator system for use in simulating fabrication or construction comprises a simulation tool with a magnet mounted on a working end, a simulation workpiece comprising a substrate with an alignment location and at least one tool path indicator; and a sensor device with a corresponding alignment location and at least one magnetic sensor. The simulation tool may comprise a pivotable attachment block mounted on a handle. Different welding accessories may be mounted to the attachment block, and the orientation of the attachment block may be altered to simulate a particular type of welding tool.

A multilayered printed matter is made up of a plurality of layers formed on a medium, including a front layer and a back layer with patterns printed thereon, and a white layer and a black layer interposed between the front layer and the back layer so as to conceal the back layer to be invisible from the front-layer side. The system for producing the multilayered printed matter includes a computer that executes a printing step of moving the medium and an inkjet head relative to each other using a moving device and printing the front, back, white, and black layers on the medium using the inkjet head, and a cutting step, subsequent to the printing step, of moving the medium and a cutting blade relative to each other using the moving device and cutting the medium using the cutting blade.

An appreciation card including a front panel having a window formed therein that is located between the left side and the right side of the front panel and being defined by a window border. A gift card panel is disposed on the back face of the front panel below the window border. The gift card panel includes a pocket section and an attachment tab, the pocket section being connected to the window border on a first end and to the attachment tab at an opposing second end, the attachment tab being adhered to the back face of the front panel, and the pocket section being free from the back face of the front panel. The front panel and the gift card panel define a gift card slot into which a gift card may be inserted.

A security element for a security paper, value document or the like, having a carrier which has a motif region that includes a visually perceptible motif with a first and a second motif part, wherein the motif region includes a first micro-optic representation arrangement which presents at least two different images in viewing angle-dependent fashion as a first motif part, and a second micro-optic representation arrangement which presents a reflective surface as a second motif part, which surface appears bulged relative to the actual macroscopic spatial form of the second micro-optic representation arrangement.
