Virtual Solution For Fashion Design
Knitting machine manufacturer Shima Seiki brings an innovative design system to the fashion design market.
TW Special Report
Color is one of the most important issues in fashion design, so special care was taken to utilize a color management system. The system starts with a color-calibrated Adobe® RGB color gamut monitor and ends with a color-calibrated printer output using an I1 photospectrophotometer included for measuring exact colors. This setup ensures the highest possible color fidelity all the way from monitor to printer, Shima Seiki reports.
The system is aimed at the fashion design market and includes software to develop designs for flat bed knitwear, prints, circular knitwear and woven fabric.
The concept uses newly designed yarns, scanned yarns, or simulated twisted yarns to generate virtually spun yarns that can be used in realistic loop simulation to create convincing fabric textures. These creations can be used to generate a realistic-looking complete virtual garment or a virtual sample. This capability is based on Shima Seiki's knowledge about how yarns move through a knitting machine.
Using a mesh mapping technique, SDS-One Apex3 enables a virtual sample to be superimposed on top of a photograph following the modulation of the light in the photograph.
Color variations can be created within the system using Pantone® color selection or color variations that the system generates by picking up colors in an image. The colors selected in this manner can be replaced automatically by the nearest Pantone color.
A library of more than 1,000 stitch patterns allows a designer to develop knitwear without having to know how to create the actual machine program for the knitting machine. New patterns easily can be created by combining and editing existing stitch data, according to Shima Seiki.
The system offers several advantages. The time to market for the fashion design is drastically shortened because it takes less time to develop a virtual sample on the SDS-One Apex3 computer than it would take to make a real sample.
For example, the time needed to prepare the machinery to produce the sample and the shipping time from factory to designer is eliminated. The designer can create a realistic virtual sample in just a few hours instead of waiting weeks to receive the actual sample.
Also, large cost reductions can be realized because there is no need to order small quantities of yarn, with the associated surcharges, to produce samples. Nor is it necessary to stop expensive equipment in production to create the samples, not to mention saving the time required by the technician to create the samples.
All that is required is less than 1 meter of the yarn that is going to be used for the project and the SDS-One Apex3 workstation to make a complete virtual sample. And even the yarn is not necessary because the system also can create yarns — including mélange yarns — that then may be made into actual yarns in cooperation with a yarn spinner.
Jacquard patterns and basic structure patterns are stored in a database. For knitwear, a generic machine code (right) is generated based on the virtual sample (left).
The SDS-One Apex3 also facilitates communication between the designer and the factory. For circular or flat bed knitwear, a generic machine code is generated that can be used by the technician in the factory to jumpstart the programming of the machinery. Shima Seiki notes that every design aspect, whether it be a cable or a color accent, is guaranteed to be spot-on at the right position on the garment as it was designed on the SDS-One Apex3.
For woven fabrics, the system outputs a complete layout of the yarns and colors to be used to create the fabric.
With regards to print design, the system allows easy creation of a repeat image and shows both normal and stepped repeats on screen, simulating a complete print design. Using specialized tools like Pattern Pen, embroidery options, effects filters and source images, a designer has the freedom to let his or her creativity blossom, Shima Seiki reports.
All of this design work can be turned into a product presentation using a technique called mesh mapping. This function employs an existing photograph on which the virtual loop simulation image is superimposed following the modulation of light on the photograph. Mapping produces a realistic representation of how the final product will look and is useful for customer presentations as well as visual merchandising.
The SDS-One Apex3 is supplied with a full-fledged Pattern, Grading and Marking system (PGM), allowing designers first to develop a pattern and then to use Shima Seiki's newly developed 3D fitting simulator to ensure correct fit. The system offers standard mannequins, or users may opt to input their own mannequin information using an optional 3D scanner or by using readymade digital mannequins.
