ROLE OF COMPUTER IN GARMENT DESIGNING

 

INTRODUCTION

 

CAD or Computer-aided design has brought a revolution in the Textile Industry. In today's world, the Textile Industry is being modernized day by day. The designs are used in different textiles manufacturing processes made in CAD. The Textile Industry, which wants to stand out from the crowd and be a renowned and a reliable one, must have the CAD system or CAD software in their manu-facturing process. CAD has made the time consuming and cumbersome process of textile designing easier. Now thoughtful and innovative designs are available to the textile designers and textile manufac-turers. CAD is an electronic tool that enables you to make quick and accurate drawings with the use of a computer. Unlike the traditional methods of making drawings on a drawing board, with CAD you can sit back in an easy chair and create wonderful drawings just by the click of the mouse. Moreover, drawings created with CAD have a number of advantages over drawings created on a drawing board. CAD drawings are neat, clean and highly presentable. Textile drawings can be modified quite easily and can be presented in a variety of formats.

 

CAD- WHAT IS IT?

 

When the products in pre-manufacturing stage are designed with the help of computer-based tools, it is termed as CAD or Computer-aided design. Sometimes the acronyms such as CADD or CAID are also used for "Computer-aided design and drafting" and 'Computer-aided Industrial De-sign' respectively. These terms are mostly used in the sectors related to the manufacturing of engineer-ing goods. As far as textile industry is concerned, CAD is generally used for interpreting computerized designing. It includes both software and sometimes special-purpose hardware.

 

APPLICATION OF CAD

 

The textile designs are the original works of the designers. CAD helps them to visualize and see their imaginative design in the final form without producing any sample watch. Sometimes, the custom-ers too provide ideas for designing according to their requirements. These are in the form of painted artwork or fabric samples and sometimes film negatives. The textile designers, with the help of CAD, convert them into workable designs. For this to be done, the sample is scanned with the help of either scanners or digital cameras and then is edited to obtain the final design of a fabric.

 

CAD is an accurate pattern making software for perfect fitting garments. It is an integrated suit of software, including pattern design, grading, detailing, marker layout and CAD drafting. A practical affordable pattern making software system is ideal for home based or commercial business.

 

Different areas of Textiles where the CAD systems are mostly used in:

 

            Textile Design System: Most fabrics, yarn dyes, Plain weaves, jacquards or dobbies can be de-signed using a CAD.

 

            Knitted Fabrics: Some systems specialize in knitwear production and final knitted design can be viewed on screen with indication of all stitch formation.

 

Printed Fabrics: The print motif can be resized, recoloured, rotated or multiplied depending on the designer's goal. New CAD systems are coming which have built in software to match swatch colour to screen color to printer color automatically.

            Sketch Pad Systems: There are graphic programs that allow the designer to use pen or styles on electronic pad or tablet thereby creating freehand images which are stored in the computer.

 

            Embroidery Systems: It requires assigned color and stitch to different parts of the design. Data is fed and multiple head work. Scanned images can also be used.

 

            Digitizing Systems: This can be done by defining the X, Y co-ordinates of series of selected prints around the pattern.

 

            Grading Systems: Certain points considered as 'Growth Points' at which the pattern has to be increased to accommodate different body size like 32/34/36 and so on (Fig.15.1).

 

            Marker Making Systems: It ensures minimal wastage of fabric. Striped fabric can also be done.

 

            Cutting Operations: Automated Cutting machines can be used after direction from marker making.

 

So, it is said that, the CAD in Textiles is really dominating with its exclusive features and efficiency. CAD helps textile designers to make a new design in a more efficient way within a shorter duration. In every section of Textile, the Weaving CAD, the Printing CAD, the Marker Making CAD etc. are being used.


CAD HARDWARE AND SOFTWARE

 

Generally speaking, computer hardware and software can be described as follows:

 

Hardware : Computer hardware is the equipment that can be observed. This could include equip-ments such as the monitor, hard-drive, keyboard and mouse. Peripherals can be added to the hard-ware to perform certain tasks and could include plotters, digitizing tables or printers.

 

Operating systems : An operating system is the vehicle through which the hardware can read the software programmes. These operating systems are used in combination with software programmes. Certain software programmes can only operate on specific operating systems. Examples of operating systems could be Windows, Linux or Mac.

 

Software : Software programmes are written to perform certain tasks. For example, the software programme, Microsoft Office is generally used, when writing documents. Other software programmes, such as Corel Draw, are used to create or modify graphic images. Generic software programmes are software programmes, which can be used in a number of disciplines. Corel Draw can be used for design in Graphic Design as well as Fashion Design. Dedicated software is written solely for use in a specific discipline. For example Stork is a software programme written exclusively for use in design.

 

TEXTILE SOFTWARES

 

The usefulness of CAD has driven the market to produce specific software for different aspects of textile and apparel manufacturing. If there are software for designing footwear, caps and bags, there are pattern-making software too for fashion industry. There are solutions for sewn goods industry as well as systems for the design of jacquard woven fabrics. The garment pattern designs are even available in home, expert, and professional versions. Precision cutting systems, cutting and plotting systems, pat-tern design, grading and marker making- you name it and there is software for every textile related work- this is IT revolution in textile industry.

 

TYPES OF CAD SOFTWARE

 

Software developers have benefited immensely by developing various CAD software. Various CAD software offer two-dimensional designs, as well as three-dimensional designs. CAD has made it possible for two people in two remote corners of the world to design and create new products using CAD software through the Internet. Artists, mechanical, electronics and civil engineers, architects and interior decorators use CAD software to aid in their designing process.

 

Designers have two kinds of CAD software to choose, either use the existing 2-D CAD software or go for more advanced 3-D CAD software. Some applications are inherently 2-D based. AutoCAD, Cad key, CADDS 5, Medusa, and CATIA v4 are examples of 2D CAD software.

 

DESIGNING SOFTWARE

 

Corel draws, Adobe illustrator, Adobe Photoshop are popular programmes used by designers in various fields and several companies publish software.

 

1 Corel Draw

 

Corel draw is a vector graphic software, allowing the user to produce world-class illustrations with 16.7 million colours.

 

Salient Features

 

            Create illustrations from scratch, enhance the designs, use and embellish scanned photos of de-signs and export designs in many ways.

 

            A vector based drawing programme with extensive text handling and precision-drawing features can be used to enhance a design.

 

            It is an ideal tool for virtually any design project from designing to technical illustrations, advertise-ments, publishing and Internet publishing.

 

Application

 

            Full colour design illustration.

 

            Complex design drawing

 

            Fashion designing

 

            Photo realistic design image

 

            Surrealistic image

 

            Animation sequences

 

            Libraries of designs

 

            High quality drawing from low resolution originals

 

            Web page designing.

 

2 Adobe Illustrator

 

Adobe illustrator is the designing and pattern making software. Illustrator is not a tailor made fashion application. It can also do many other things that fashion specific applications can't. Illustrator is a very powerful tool for any graphic design work you can throw at. It is in many ways a jack of all trades, capable of doing a range of tasks such as graphic design, fashion sketches, fashion illustration, trim design, fashion prints and so on. Illustrator is at first, a fashion design production tool by fashion design production. These will then be of a high standard. to be sent straight to the factory, to start prototypes production.

 

Adobe illustrator has long been considered the norm for drawing technically correct and detailed plans of-* flats. However, some industry individuals comment that the computer generated flats have a sense of looking 'too perfect' regardless of your preference, if there is a hand drawn flat that needs to be copied to look very technical.

 

3 Adobe Photoshop

 

In designing, Photoshop is ever evolving and is primarily marked for the photo retouching and graphic design industries. It will never truly address the full needs of the textile market. However it is a great stepping stone for designers to begin their journey with CAD.


PATTERN MAKING SOFTWARE

 

Gerber : Computer aided design, commonly referred to as CAD, Gerber is known as a leading supplier in high technology and solutions. The company develops hardware and software to automate pattern design, grading and marker making. Since the 1960s, it offers solutions for companies to remain up-to-date with technology and fashion. Their goal is to help designers and pattern makers work as efficiently as possible in an automated environment for a quick turnaround of final designs garments and products. Gerber technology is used in the apparel, furniture, transportation, industrial fabrics and composites industries. If it is a sewn product, it is likely to be created on a Gerber system.

 

Pattern Designing Software (PDS) is widespread in Germany and Italy. The other new develop-ment in the market place of system software is Pattern Generation Software (PGS). At present the two packages have been used called conex and PGS.

 

ADVANTAGES OF CAD

 

Easy to operate designing system- CAD has many advantages.

 

            The expense and time is reduced in a considerable manner when compared to the laborious manual work of designing.

 

            Designing can be done from anywhere, as the customers are able to control the process from remote locations as well.

 

            The data can be easily stored, transmitted, and transported through computer files.

 

            Digital swatches can be saved on floppy disks, zip disks, CD-ROM or hard drive thus saving space. Moreover they can be easily organized for fast and easy retrieval.

 

            The designs can be easily customized and personalized as corrections and editing can be done at any time without significant delays or cost increases.

 

            The designers do not need to produce swatches all the time as they can now see how a particular fabric or garment looks in different colors and shapes on the computer screen itself.

 

CONCLUSION

 

With all its benefits, care too has to be taken before going for any CAD software. The software, which is supported by the available hardware, should only be purchased or the hardware should be upgraded to comply with the new software. Training too has to be given to the people who operate the system so that maximum benefit may be taken from it. With careful selection and trained professionals, the textile industry can enjoy the benefits of the IT revolution right at their door.
