Mr Lalith, Mr Salman and Mr Arsalan for assisting in the collection of the topics for the chapters. And Most especially to my family and friends.

ABSTRACT

Marker is a part of a paper on which the patterns of all parts of the garments are drawn so that garments can be made by using minimum quantity of fabric. Reducing the quantity means that maker is being made efficient so that fabric wastage can be reduced as much as possible. There are two methods of marker making, the first one is manually in which a specialized marker maker makes the makers and try to utilize all the fabric so that another piece of fabric is not required. The other method is computerized method called Gerber Technology. In it the markers are made in computers and the efficiency is set by computer to decrease the fabric wastage. Saving the fabric is crucial because is decrease the average cost so that profit maximization can occur. After conducting experiments the best method for increasing the marker efficiency is Gerber (computerized). It makes the most efficient markers which decreases the wastage of fabric. This saves the cost and benefits the garment manufactures as they can make several pieces (patterns) out of less fabric.

INTRODUCTION

In recent years the number of markers required by apparel manufacturers has escalated disproportionately to growth. Orders are getting smaller, the number of different styles is increasing, and lead times are getting shorter - all of which put more pressure on the marker making department. So it is no surprise that new automated marker making tools are being launched onto the market. Niki Tait takes a look. The improved fabric utilisation associated with computerised marker making has helped this technology virtually take over from traditional manual methods over the last 25 to 30 years. With fabric accounting for around 50 per cent of the ex-factory cost of a garment (more than 70 per cent in low cost labour countries), the 5 per cent saving associated with automated systems is key. In reality these marker making tools are 'computer assisted' rather than 'computerised,' with the skill of piece placement still relying on the experience of the marker maker. The computer plays a passive role, controlling the nesting constraints such as tilting, rotation and buffering while the operator makes all the decisions. An experienced marker maker will remember combinations which have worked before, he can see what part might fit into which slot, and he knows what he can tilt slightly off gain to fit. In the last few years, however, CAD companies and research organisations throughout the world have been working to develop systems to produce markers fully automatically. It's an extremely complex process...
