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.

The present invention relates to particles of naphthalocyanine and phthalocyanine chromophores of formula (I) having a number average particle size in the range of from 10 nm to 80 nm with standard deviation being less than 40 nm, their use as almost colourless IR absorbers, for optical filter applications, especially for plasma display panels, or for laser welding of plastics. The compounds may be used in compositions for inks, paints and plastics, especially in a wide variety of printing systems and are particularly well-suited for security applications.

A pattern forming apparatus for forming a pattern by emitting a scanning light onto a plurality of base materials conveyed in a predetermined conveying direction, includes a plurality of emitting units including a first emitting unit and a second emitting unit. The first emitting unit includes a first light source unit to emit a first laser light; a first conveying direction light scanning unit to scan the first laser light in the predetermined conveying direction; a first intersecting direction light scanning unit to scan a scanning light, scanned by the first conveying direction light scanning unit, in an intersecting direction that intersects the predetermined conveying direction. Further, there is a first light emitting unit to emit a first scanning light, scanned by the first intersecting direction light scanning unit, onto a base material among the plurality of base materials.

A particle and a method for producing the same is disclosed. For example, the particle includes a polymer resin that is compatible with a three-dimensional (3D) printing process to print a three-dimensional (3D) object and a marking additive that allows selective portions of the 3D object to change color when exposed to a light, wherein the marking additive is added to approximately 0.01 to 25.00 weight percent (wt %).

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.
