Abstract: A system and method for characterization of patterns marked on a fabric. The system includes a light source generating a light beam to impinge on a fabric; an optical arrangement including a parabolic mirror with a hole and an optical device, directing said light beam towards the fabric; a wavelength division unit; a light detection unit; and a computing device. The optical device changes and orients the direction of the light beam towards the fabric providing a scan of an area of the fabric, line-by-line, and redirects scattered light towards the light detection unit. The wavelength division unit separates the scattered light into spectral bands or colors and the computing device characterizes a pattern marked on the fabric by executing an algorithm that analyzes electrical voltage signals and that computes a quality measure of said marked pattern.

Abstract: Method and apparatus for treating cloths by spraying with a chemical dispersion including a liquid, the method including: inserting the cloths in a drum that is rotatable about its longitudinal axis, the drum including paddles, where for each of at least two of the paddles the paddle's longitudinal axis forms an angle ? of between 5 degrees and 85 degrees with the geometrical orthogonal projection of the paddle's longitudinal axis on a geometrical plane which is normal to the drum's longitudinal axis; with a dispersion supply system providing the chemical dispersion to spraying elements; with rotation elements rotating the drum about its longitudinal axis and reversing the rotational direction at least once, and with spraying elements spraying the drum's interior with the dispersion, the spraying elements being attached a to movable door of a chamber enclosing the drum. The apparatus is adapted for executing the method.

Abstract: A method for laser engraving on clothing and to a corresponding machine. Using an image, a laser burns, for each pixel, a corresponding point on the clothing, with a laser energy level that is a function of the pixel value. This function has a first zone with a first average gradient and a second zone with a second average gradient. The first zone corresponds to laser energy values less than the second zone, the absolute value of the second average gradient being greater than the absolute value of the first average gradient. The laser engraving machine comprises a laser source, means for conducting the laser on specific points of the clothing, means for controlling the energy supplied by the laser, and control means configured to carry out the method.
