"Planning the fabric layout" in the garment industry refers to arranging pattern pieces on the fabric in the most efficient way to minimize fabric waste when cutting. This efficient layout is called a
marker. Let's analyze the options:
- (a) Digitizer: A digitizer is a tool used to convert physical paper patterns into digital data that can be used in CAD (Computer-Aided Design) systems. It's part of the process of creating digital patterns, but not the layout planning itself.
- (b) Marker (or Marker Making): A marker is a diagram or plan showing the optimal arrangement of all the pattern pieces for all the sizes of a garment that need to be cut from a lay of fabric. The goal of marker making is to achieve the highest possible fabric utilization (i.e., minimize waste). Markers can be made manually (by drawing on paper placed on top of the fabric lay) or, more commonly now, using CAD software which can automatically generate highly efficient markers. An economical fabric layout is achieved through good marker planning.
- (c) Sloper (or Block Pattern): A sloper is a basic, close-fitting pattern (without seam allowances or design details) that is drafted to an individual's measurements or to standard size chart measurements. It serves as a template from which patterns for different garment styles are developed. It's a foundational tool for pattern making, not for fabric layout planning of multiple pieces.
- (d) Conveyor: A conveyor is a material handling system used to move materials or products within a factory. It's part of the production logistics, not directly involved in planning fabric layout. (Automated cutting systems might use conveyors to move fabric lays).
The most economical way of planning the fabric layout to minimize waste is achieved through efficient
marker making. The marker itself is the plan for this layout. \[ \boxed{\text{Marker}} \]
