The present invention relates to architected stamps having beneficial printing properties. In particular, negative Poisson ratio structures and/or porous reservoirs can be employed to control fluid dynamics and to provide metered ink transfer.

A cosmetic stamp is shown. It includes a a stamping element body, with a first portion coupled to a second portion. It also includes a first cosmetic stamping element removably coupled to a first side of the first portion. The first cosmetic stamping element includes an applicator. The stamp also has a second cosmetic stamping element removably coupled to a second side of the first portion. The second cosmetic stamping element includes a second applicator. At least one cosmetic component is also housed in the stamping element body. The first applicator and second applicator are removably coupled within said stamping element body.

A method of manufacturing an imprint stamp including forming an imprint resist only in a second area of a sample substrate including a first area and the second area, pressing the imprint resist with the imprint stamp and curing the imprint resist, in which the imprint stamp includes a fine protrusion pattern that corresponds to the first area and the second area of the sample substrate, and separating the imprint stamp from the sample substrate such that a portion of the fine protrusion pattern corresponding to the second area is separated from the imprint stamp by the cured imprint resist.

A method includes producing a stamp impression with UV-curable ink with a preferably self-inking stamp. A stamp for this purpose, includes a text plate with the negative stamp impression is moved from a resting position into a stamping position, whereby in the stamping position the stamp impression with the ink is produced on a preferably smooth surface of a document or object or workpiece, and then the text plate is returned to the resting position, wherein a controller is activated, wherein for the curing of the ink at least one or several irradiation sources arranged on the stamp is or are, respectively, switched on, with UV rays aligned in the direction of a printing surface.

A cosmetic stamp includes one or more stamping elements, a stamp compartment or housing for carrying the one or more stamping elements and a stamping substance. For example, a cosmetic stamp is an eyebrow stamp that is used for the application of a cosmetic eyebrow using the one or more stamping elements and the stamping substance. A method of applying a cosmetic stamp includes removing a stamping element from a stamp compartment, opening a lid of the stamp compartment, and pressing the face of the stamp to a stamping substance.

Methods of printing nanoparticulate ink using nanoporous print stamps are disclosed. A nanoporous print stamp can include a substrate, a patterned arrangement of carbon nanotubes disposed on the substrate, and a secondary material disposed on the carbon nanotubes to reduce capillary-induced deformation of the patterned arrangement of carbon nanotubes when printing nanoparticulate ink. Some methods include loading a nanoporous print stamp with nanoparticulate colloidal ink such that the nanoparticulate colloidal ink is drawn into microstructures of the patterned arrangement of carbon nanotubes via capillary wicking. Nanoparticulate colloidal ink can include nanoparticles dispersed in a solution. The method also includes contacting a nanoporous stamp to a target substrate to form nanoscale contact points between the target substrate and the patterned arrangement of carbon nanotubes of the nanoporous print stamp so that nanoparticulate colloidal ink is drawn out of the nanoporous print stamp and onto the target substrate to form a pattern.
