Abstract
A number of new laser patterns are defined by laser scribing the material. This produces new laser patterns which have not previously been known.
Claims17
A method, comprising:
- setting specified parameters on a controllable laser, said specified parameters being parameters which control an amount of energy that is applied to a denim workpiece to alter a surface chemistry of the denim in a way to change the look of the denim according to a pattern without undesirably damaging the denim;
- and
- using said controllable laser to modify the look of an entire width of a denim article per single traverse of the laser as the output of the laser passes across the denim article.
A system comprising:
- a material holding part, which holds a workpiece to be processed;
- a controllable laser, which is controllable according to specified parameters which control power output and position of the laser to alter a surface chemistry of the workpiece where an entire width of the workpiece is altered per single traverse of the laser.
A method, comprising:
- setting specified parameters on a controllable laser, said specified parameters including an energy density per-unit time that marks a denim material without undesirably damaging the denim material, wherein said marking comprises changing a look of the denim material in a way which can be seen by a user, and wherein said specified parameters comprise parameters which causes a pattern to be formed on said denim which pattern repeats across an entire unit area of said denim;
- and
- using the controllable laser to modify the look of the denim according to said specified parameters to form a plurality of unit area patterns on the denim.
