At least one embodiment of the present invention pertains to printing. More specifically, at least one embodiment of the present invention pertains to fabric printing on nested patterns.
In conventional fabric printing and garment design and production, garment patterns are applied to printed fabrics, for instance, at the present time, a typical workflow for fabric printing and the use of nested patterns can include the following tasks or process steps:
A design pattern is defined using graphic design tools, such as Adobe Photoshop or Adobe Illustrator. The fabric is printed to the defined design, either using an analog printer, e.g. a rotary or flat-screen printer, or digitally, such as using a combination of a digital front end (DFE) and raster image processing (RIP), and a corresponding digital inkjet press. Most of the time, the design pattern is expressed by stepping and repeating on the fabric with a basic building block. The fabric can be produced with different “color ways” for the same graphic designs. For instance, a garment design may often be produced with two or three color ways, e.g., in blue tones or earth tones.
The design of the garment can often be created using graphic design tools, such as Adobe Photoshop or Adobe Illustrator. The design can then be converted to a corresponding technical design, using 2D/3D CAD systems such as EFI-Optitex. The output of this process is a set of cut and sew patterns, with the selected fabric position and rotation assigned properly to the cut patterns.
The set of cut and sew patterns are then aligned properly to the pre-fabricated fabric, taking into account positioning on the fabric, after which the cut patterns are sent to the cut and sew manufacturing facility, for the final assembly of the garment. The process of aligning the cut pattern to the proper place in the fabric graphic patterns creates waste in fabric utilization.
In such a conventional process, textile sheets and rolls are pre-printed with designs and graphics, and are subsequently placed on cutting tables, to be used for nesting and cutting design patterns, which are later sewed into a final textiles consumable, e.g., garments, bedding, etc.
In the conventional process described above, there is often substantial waste in the printing of fabrics, because there is no prior knowledge of what the specific fabric elements geometries are, and how they match the prints.
Also, such conventional methods mandate specific nesting of the fabric pattern elements to the textile texture print to match the required print design, which can result in poor cutting yields, due to a high level of constraints between the pattern geometries and the textile sheet print.
One or more embodiments of the present invention are illustrated by way of example and not limitation in the figures of the accompanying drawings, in which like references indicate similar elements.
References in this description to “an embodiment”, “one embodiment”, or the like, mean that the particular feature, function, structure or characteristic being described is included in at least one embodiment of the present invention. Occurrences of such phrases in this specification do not necessarily all refer to the same embodiment. On the other hand, the embodiments referred to also are not necessarily mutually exclusive.
Introduced here is are technique that allows effective nesting of fabric, as part of a textile cutting process, in which designs and/or graphic elements are directly printed on the nested elements, instead of on the entire textile sheet.
Certain embodiments of the invention can address issues of waste and redundant printing, such as by starting with a blank textile roll, and printing only in the geometry areas of the patterns.
Certain embodiments of the invention can increase fabric yield, because there are no constraints between the pattern geometries and the textile sheet print.
Various exemplary embodiments will now be described. The following description provides certain specific details for a thorough understanding and enabling description of these examples. One skilled in the relevant technology will understand, however, that some of the disclosed embodiments may be practiced without many of these details.
Likewise, one skilled in the relevant technology will also understand that some of the embodiments may include many other obvious features not described in detail herein. Additionally, some well-known structures or functions may not be shown or described in detail below, to avoid unnecessarily obscuring the relevant descriptions of the various examples.
The terminology used below is to be interpreted in its broadest reasonable manner, even though it is being used in conjunction with a detailed description of certain specific examples of the embodiments. Indeed, certain terms may even be emphasized below; however, any terminology intended to be interpreted in any restricted manner will be overtly and specifically defined as such in this Detailed Description section.
Embodiments of the invention concern a method that couples effective nesting of fabric as part of the textile cutting process with direct printing designs on the nested elements instead of the entire textile sheet.
Embodiments of the invention address both the waste in redundant printing because it uses a blank textile role to start with and prints only in the patterns geometry areas. Embodiments of the invention also increase fabric yield because there are no constraints between the pattern geometries and the textile sheet print.
A design of the garment 14 can created 404 (
In an embodiment, the nesting, i.e. the positioning of the design or cut patterns 42, is performed as if it is for a “white” fabric, i.e. without any consideration to the design pattern, which in some embodiments can be laid out as densely as possible, to minimize fabric waste. In some embodiments, this process may be done with the Optitex CAD system.
In some embodiments, the nesting layout 80, once defined, can be sent to the DFE/RIP/Printer 508 (
In
The illustrative process seen in
The process 400 starts with a pattern design system or module 502 (
In some embodiment, the pattern design system or module 503 can also create 404 the detailed print design for each geometry, in high quality, and can store the print design and output it for both nesting and for direct print. For instance, to accomplish this objective, the base print pattern is combined with the part geometry at the right place to match the other parts' geometries. The placement can be done manually via computer human interface for placing, moving, scaling, and rotating the basic print patterns 42 manually or automatically. In some embodiments, the placement is done per rules of harmonizing the appearance of design elements 22 which may flow from one geometric part 42 to one or more neighboring parts 42.
In some embodiments, the nesting 405 can use the geometries generated by the pattern design system 502,504, and arranges them efficiently per the required volume and variety of sizes on a fabric sheet with specific dimensions, e.g., the available width 304 and length 302 of the fabric 302. In some embodiments, the digital print system 508 allows printing of any image in any shape on a gray or dyed fabric.
Once efficient arrangement is achieved, via automated nesting and/or manual manipulation of the geometric patterns, the specific print design is added and presented, such as seen in
In some embodiments, the resulting nested printed patterns geometries are sent to the digital printing system 508, such as a single big image, representing the entire arrangement. In some embodiments, the design and/or corresponding metadata can indicate the total count of the needed pieces for each color way. In some embodiments, the system can be configured to send the collection of pieces, represented as graphic files with the graphics and the shape descriptions, to the digital front end (DFE) 510 driving the digital press 512 (
In some embodiments, when a single composed image is sent, this image includes only the print elements 22 inside the patterns geometries 42 and not the geometries themselves 42 in their final position on the print area. In some embodiments, in which the collection of patterns to be nested by the DFE 510 is sent to the printer 508, the geometry (Clip path) is sent as well. In some embodiments, a standard cutting file is additionally generated, to be used in the cutting process, in which the cutting file includes cutting instructions and/or a marker file.
The process 400 also typically performs exact color matching calibration, raster image processing (RIP), and is directed to the final printing phase, in which an industrial printer 512 digitally prints the entire arrangement as a single big image on the textile sheet 302. In some embodiments, reference marks are printed as well, to indicate bias location of the fabric sheet 302, for later use when placing on the cutting table 514.
Following the printing 410, the fabric sheet 302 is typically placed and positioned, using the reference marks, on a standard cutting table 514 and, using the cutting file created, a standard cutting process take place, resulting with cutting 412 the fabric 302 into the design patterns 42, which already include their prints 202 as created in the print phase 410.
Some embodiments of the system 500 combine an Optitex PDS system for pattern design 402, an Optitex Marker system for nesting 405, an EFI Fiery for color matching and RIP, i.e., prepress 408, and an EFI Textile printer 512 for direct printing 410 of the required textures on the nested patterns.
