A solvent layer is coated on a metal layer carried by a donor substrate, allowing the fabrication of solid metal lines at a high resolution. The laser jetting involves ejecting metal particles, constrained within a solvent membrane, from the metal layer. Once the metal particles have been deposited onto a receiver substrate, the solvent can be evaporated. Since this printing procedure can be performed with the solvent layer in direct contact with the receiver substrate or separated therefrom by a small distance, the resolution of the metal lines can be very high and depends directly on the laser spot size and defocus. The solvent constrains the droplet size of the metal particles, which can increase or maintain the resolution of the laser beam. As this process is a continuous sequence production, the metal line production can be performed at a very rapid rate.

Embodiments are directed to laser-based processes for forming features on the surface of a part. The feature may include a geometric element, a color element, and/or a surface finish element. In some cases, the laser-formed features are formed as a pattern of textured features that produce an aesthetic and/or tactile effect on the surface of the part. In some cases, the texture features may be sufficiently small that they may not be discerned by the unaided human eye. Also, in some cases, a multiple laser-based processes are combined to form a single feature or a finished part having a specific aesthetic and/or tactile effect.

Provided is a laminated body in which a print layer is provided downstream of a laser color development layer without lowering quality. A card is provided with an offset print layer laminated on a base material, a buffer layer laminated on the offset print layer and having translucency, and a laser color development layer laminated on the buffer layer. The buffer layer minimizes scratches on the offset print layer that occur with the heat generation of the laser color development layer.

Provided is a photo printer including: a base for accommodating paper therein; a pick-up roller protruding from a bottom surface of the base to feed the paper accommodated in the base in a forward direction; a platen roller for discharging in the forward direction the paper; a head provided above the platen roller to apply heat to the paper; a swing bracket having a front side to which the head is coupled and a rear side rotatably coupled to the base; pressurizing means for pressurizing the swing bracket down to allow the swing bracket to come into close contact with the paper; and head supporting members provided on side walls of the base to support the front side of the swing bracket under the swing bracket and each having an eccentric portion adapted to lift the head up through rotation.

A laser marking system (10) comprises a marking controller (11) operable to control a plurality of laser diodes (13) to emit light through optical fibre (14) such that the emitting, ends of the optical fibres (14) form a multi-emitter array. Light emitted from the emitting ends of the optical fibres (14) is focussed by a lensing arrangement (15) on a substrate (16). The lensing arrangement (15) is substantially telecentric such that the non-telecentric angle, θ.sub.t, of the telecentric lens assembly satisfies (Formula I) where θ.sub.1/2 is the half angle divergence of the emitter beam and 1/F is the fraction of the emitter spot diameter d.sub.o that corresponds to the maximum acceptable displacement in the image plane.

A method for marking an article may comprise forming a raised pad on a substrate of the existing article by applying a material to a surface of the substrate using a material addition process, and forming a design on a surface of the raised pad. The raised pad may be formed on the surface of the substrate to prevent mechanical stress from being propagated from the raised pad to the substrate in response to the design being formed on the raised pad.

A method of forming a non-optically detectable identifiable marking invisible to the naked eye is formed from plural recesses of multiple levels at an outer surface of an article formed from a solid-state material. The method includes forming plural recesses of multiple levels within a predetermined region of a photoresist applied to an outer surface of an article formed from a solid-state material. The plural recesses are formed by grayscale lithography and the recesses extend at least partially through the photoresist and towards the outer surface of the article formed from a solid-state material. The method also includes applying an etching process such that at least a portion of the outer surface of said article is exposed and etched to form plural etched portions extending into the article from its outer surface and corresponding to plural recesses; wherein said predetermined region of said photoresist defines an identifiable marking to be applied to the outer surface of said article; wherein said plurality of etched portions forms the non-optically identifiable marking on the outer surface of said article.
