摘要： Easy reading of a read code is enabled without matching a read range with a specific print section, and without impairing designability of a cylindrical container and clarity of a display print.
A cylindrical container has, on the outer surface thereof, a print layer. The print layer has an electronic watermark layer including an electronic watermark image printed thereon, and a blindfold layer that renders the electronic watermark image difficult to be visually recognized. The print area of the blindfold layer matches a part or entirety of the print area of the electronic watermark layer.

摘要： A determination system includes an imaging data acquisition device that captures an image of a printed surface of a printed product to acquire imaging data of the captured image, and a determination device that determines, based on the imaging data, a printing method used to produce the printed surface of the printed product for which the image is captured by the imaging data acquisition device. The determination device selects a plurality of determination areas included in the captured image, acquires determination data based on a line-segment image included in each of the determination areas, compares the acquired determination data between two determination areas, and acquires, based on a result of the comparison, a determination value for determining a printing method used to produce the printed surface of the printed product, and determines, based on the determination value, a printing method used to produce the printed surface of the printed product.

摘要： A redundantly printed security-enhanced document, printing method and system ensure the meaning of the information imparted by variable indicia printed by redundant printing on the document with removable scratch-off coatings. By printing the variable indicia with multiple colors, redundancy and integrity of the intended indicia is achieved. Additionally, inverted color indicia countermeasures to pinprick attacks are also disclosed. The redundantly printed document, methods and systems enhance the overall appearance of the redundantly printed document, and reduce possible consequences resulting from misprinted variable indicia. The resultant printed process color indicia maintains a grayscale equivalent level of a process color greater than or equal to the measured grayscale equivalent level of the substrate surface plus an additional contrast delta of 15%.

摘要： The present invention relates to microparticle compositions comprising an organic IR absorbing pigment having a main absorption maximum in the range from 750 to 1100 nm. The invention also relates to a process for producing said microparticle compositions and to their use in a printing ink, in particular in a printing ink, which is suitable for producing a security feature or a security document. The microparticles of the pigment composition contain the organic IR absorbing pigment as solid particles, which are surrounded by or embedded in an aminoplast polymer, which is a polycondensation product of one or more amino compounds and one or more aldehydes. The microparticle based pigment composition is characterized by a volume based particle size distribution, as determined by static light scattering according to ISO 13320:2009 EN, having a D(4,3) value in the range from 1.0 to 15.0 μm.

摘要： An example container includes: structure having an interior and an exterior. The interior is to contain an electronic product. The exterior comprises: a first label of a first type of polychromatic ink to be activated at a first wavelength; and a second label of a second type of polychromatic ink to be activated at a second wavelength different from the first wavelength; the first label to indicate a first set of features to be configured at the electronic product using a first wireless signal; and the second label to indicate a second set of features to be configured at the electronic product using a second wireless signal. The structure is transparent to the first wireless signal and the second wireless signal.

摘要： An intaglio printing ink includes capsule luminescent pigments and a further machine-readable feature substance. The capsule luminescent pigments include at least one core with a luminescent substance and one shell encapsulating the at least one core. They are characterized by their high luminescence intensity and high chemical stability, which enables a simultaneous loading of the intaglio printing ink with a further machine-readable feature. A printing method and a printed product include the intaglio printing ink.

摘要： Disclosed is a method for manufacturing a multilayer data medium (1), in which method: a multilayer data medium, including at least one transparent security layer (16), and at least one marking layer (17), sensitive to electromagnetic-marking radiation (5), are selected; the transparent security layer (16) includes at least one semi-transparent printed image including at least one thermochromic dye; at least one marking (30) is made using the electromagnetic-marking radiation, through the printed image; the semi-transparent printed image reveals, in a first state referred to as the inactivated state, at least one semi-transparent visible pattern that makes it possible, after the marking step, to view the marking (30) through the image, the pattern not being visible in a second state, referred to as the activated state. The invention also relates to a multilayer data medium (1).
