The present invention is directed towards a security sheet and a security booklet comprising a security sheet. The present invention is further directed towards manufacturing a security sheet and security booklet and a method of authenticating a security booklet. The security sheet comprises a plastic substrate having first and second outer surfaces, at least one opaque region at least partially surrounding at least one window and perforations extending between the first and second outer surfaces. The perforations form a first data element located partially in the at least one window and partially in the at least one opaque region.

A micro-optic security device with zonal color transitions includes a planar array of focusing elements, an image icon layer including a plurality of retaining structures, the plurality of retaining structures defining isolated volumes at a first depth within the image icon layer, a first zone of image icons, the first zone of image icons having a first predefined subset of the plurality of retaining structures, wherein the isolated volumes of retaining structures of the first predefined subset of the plurality of retaining structures contain cured pigmented material of a first color, and a second zone of image icons, the second zone of image icons including a second predefined subset of the plurality of retaining structures, wherein the isolated volumes of retaining structures of the second predefined subset of the plurality of retaining structures contain cured pigmented material of a second color, wherein the second color contrasts with the first color.

An optically variable security element has a multicolored, reflective areal region including a first relief structure disposed at a higher level than a second relief structure. The first relief structure has a first ink coating and the second relief structure has a second, different ink coating. The two relief structures overlap in an overlap region. The first ink coating of the first relief structure is disposed at a higher level in the overlap region and has at least one recess the dimension of which is more than 140 μm. The first ink coating comprises an edge region adjoining the recess, and as a bicolor register feature the first relief structure lets the edge region of the first ink coating appear with a first color impression and the second relief structure through the recess lets the second ink coating appear with a second, different color impression in mutual register.

One example discloses a security device, including: a bulk security capacitance, including a first endpoint and a second endpoint, and having, a first layer including a first set of conductive elements, the first endpoint, and the second endpoint; and a second layer including a second set of conductive elements; wherein the first set of conductive elements and the second set of conductive elements together form at least two bulk capacitors in series; wherein the first and second layers are separated by a distance; and wherein the first and second endpoints are configured to be coupled to a tamper detection circuit configured to detect a change in the bulk security capacitance.

The security document, such as a passport, comprises a lightguide having an incoupler structure and in outcoupler structure. The outcoupler structure is sparse in the sense that any part of the protective area is close to a part of the outcoupler structure. However, to secure a large protective area with a limited amount of incoupled light, outcoupler structure covers no more than 20% of the protective area. This allows to protect a large area of the security document, such as a photograph or other personalized information, by means of the lightguide.
