A laser markable label or tag including a polyester film comprising a polyester resin, an optothermal converting agent, a laser markable polymer and titaniumdioxide, characterized in that the amount of titaniumoxide is at least 3 wt % relative to the total weight of the film.

A computer-implemented method for marking an object on an aligner. The aligner surface is modeled. The method includes calculating a normal for each tile in a tessellated surface and disqualifying a tile from being selected. For tiles not disqualified, a patch is identified that produces a markable area. The method includes selecting an object to be marked, calculating a location of the object in the markable area, and providing the location of the object to a marking device. Disqualifying includes comparing an angle between a normal and an orientation of the beam to an origin of the calculated normal on each tile. Disqualifying includes disqualifying the at least one tile when the angle is outside of a range of −90° to +90°. Identifying the patch includes separating the patch into at least two smaller patches, and one of the two smaller patches of tiles is the markable area.

A polyolefin composition for use as an outer layer of a cable is described, wherein the polyolefin composition comprises a multimodal olefin copolymer and carbon black and UV agent; wherein the multimodal olefin copolymer has density of 0.915-0.960 g/cm3, MFR2 of 0.1-10 g/10 min, wherein carbon black in the polyolefin composition is present in an amount of 0.25-1 wt %, and wherein the polyolefin composition has shrinkage of 1% or lower.

A method for marking at least one portion of a surface of an object, said surface being made of a material that is paper, cardboard or fabric, the method comprising the following steps: heating the surface of the material by means of a heat source to a temperature lower than a temperature at which the visual appearance of the material changes; marking the heated surface by means of a marking laser, so that the light beam of the laser raises the temperature on the surface of the material enough to change the visual appearance of said surface;

in which the marking laser is a laser with a light beam that belongs to the visible or ultraviolet spectrum.

Software and lasers are used in finishing apparel to produce a desired wear pattern or other design. A technique includes determining a fabric's response to a laser, capturing an initial image of a wear pattern on a garment, and processing the initial image to obtain a working image in grayscale. The working image is further processed to obtain a difference image by comparing each pixel relative to a dark reference. The difference image is converted to a laser values image by using the previously determined fabric response to the laser.

A layer transferring device includes: a main casing having an opening and accommodating a heat roller, a motor, and a first transmission gear therein; a film cartridge; and a cover at which a pressure roller and a second transmission gear is provided and movable about a pivot axis to open and close the opening. The heat roller is movable toward and away from the pressure roller when the cover is closed. When the film cartridge is attached to the main casing and the cover is closed, the multilayer film contacts and passes through between the pressure roller and the heat roller. When the cover is closed, the first transmission gear for receiving a driving force from the motor and the second transmission gear for transmitting a driving force to the pressure roller are positioned between the pivot axis and the heat roller and in meshing engagement with each other.

Examples of the present disclosure relate generally to a printing apparatus and, more particularly, to apparatuses, systems, and methods for printing utilizing laser print head and reactive media.

Disclosed is a method for associating a marking with an object, including the following steps:—identifying the position of at least two different elements of the marking in relation to the marking and/or the object; and—measuring a relative distance between at least two identified elements; then—recording in a database the position of at least two identified elements, and the relative distance between the identified elements so that the position of two identified elements is correlated with the measurement relating to their distance.

The procedure for tile (1) decoration comprises the following phases: providing a ceramic article (2) in raw material, provided with a flat surface to be decorated (3); depositing thoroughly a decorative powder (4) on the flat surface to be decorated (3); fixing the decorative powder (4) to the flat surface to be decorated (3) by means of radiation-emitting fixing means (5), according to a predefined drawing (6); removing the decorative powder (4) in excess to obtain a decorated ceramic article (7); firing the decorated ceramic article (7) in a kiln to obtain a tile (1).
