Problems solved by technology

[0003] The disadvantage of this method is that the colors are selected as a function of the colors that can be displayed in the output unit, for this purpose a person skilled in the art with weaving experience is required
Usually, at least at present, a maximum of 12 weft thread colors can be achieved in a weaving machine, and therefore, the number of reproducible colors is necessarily limited

Embodiment Construction

[0045] The method according to the invention comprises an initial phase in which a color scan is carried out on any desired image, which can be of any type and without any restrictions in terms of topology and size.

[0046] The images read in this way are visualized by video by means of a considerable number of colors: the number of colors is related to the performance and configuration of the hardware system used.

[0047] In this respect, starting to make selections requires a number of colors, especially directly from a video image, or by selecting within the total spectrum of the visible range of colors, thus offering an infinite choice of shades and variations.

[0048] In fact, the worker chooses the number of base colors of the weft and warp threads that he will use during the weaving process, that is to say, the number of base colors that corresponds to the number of warp and weft threads that the weaving machine can use. According to the invention, the method makes i...

Abstract

The invention relates to a method for the production of images with high resolution in jacquard fabric comprising the following steps: colour scanning of an output image to be reproduced on a fabric, video visualisation of said image with the largest number of colours possible with the means employed for said visualisation. The invention is characterised in that the method comprises further steps: selection of a number of base colours to be used for forming said image on said fabric, said number of base colours is related to the number of warp and weft threads which may be used in the loom and which are to be applied in the weaving of said fabric, reducing the original colours of the output image to a number of reduced colours which it is possible to produce by mixing the base colours of the warp and weft threads.

Description

technical field [0001] The subject of the invention is a method for producing high-resolution images in a jacquard fabric according to the preamble of claim 1 and a device for carrying out the method. Background technique [0002] EP0692562 describes a method of forming an optical image of a fabric consisting of patterned warp and weft threads. In this method, the pattern is recorded by a data processing system and displayed on a display screen, and the pattern is scanned in from a raw state. Thereafter, with the aid of CAD, the warp and weft threads forming the fabric are assigned to a weave diagram defining the weave of the fabric composed of it. These are well known regular weaves such as plain weave, satin weave, twill weave and basket weave. Subsequently, the way in which the warp and weft threads run is determined taking into account the specific parameters of the yarn and the parameters of the fabric. Corrects the intended travel of the warp and weft threads in vie...
