What is marker？
A marker is a diagram of a precise arrangement of pattern pieces for sizes of a specific style that are to be cut from in one spread.
What is marker making?
Marker making is the process of determining a most efficient layout of pattern pieces for a style, fabric and distribution of sizes (source: Apparel Manufacturing, Glock and Kunz). Factories those don’t have CAD system perform this process manually. In manual marker making to make an efficient marker one need time, skill and concentration. Now-a-day Marker making is mostly done by CAD systems which give accuracy, increase control over variables and reduces time required in making markers.
What is marker efficiency?
Marker efficiency is defined as a ratio of area of marker used in a garment and area of total marker.
Secondly, Glock and Kunz have defined this term in their book, Apparel Manufacturing as Marker efficiency is determined from fabric utilization, the percentage of total fabric that is actually used in garment parts.
Note: Marker efficiency and Fabric utilization is not same thing. In marker efficiency calculation fabric wastage due to end bits and end loss is not included but in fabric utilization calculation all kinds of fabric wastage are included.
