Quality control in marker making: Marker is a thin paper which contains all the necessary pattern pieces for all sizes for a particular style of garments. It is made just before cutting and its purpose is to minimize the wastages of fabric. In case of marker making quality is very important factor. Though quality is a relative term.
Purposes of quality control in marker making: The objectives of quality control in marker making can be summarized as:
To ensure the markers are made to a size ratio that gives the required quality and quantity per order by reducing the wastage of fabrics.
To ensure no garment part is missed in the marker and the marker is of comparable length and width of the fabric being laid.
To check notch or drill mark
Fabric width must be higher than marker width
Fabric length must be higher than marker length
Matching of green line
Check pattern size and dimension
Matching of check and stripe taking into consideration
Considering garments production plan
Cutting table length consideration
Pattern direction consideration

Cutting section starts with the receipt of piece goods and ends with the completion of the bundles of cut parts ready for sewing. The preparation for cutting is very important prior to the cutting operation. Accurate cutting simplifies the sewing and pressing operation. Cutting of fabrics or trims to size, where possible, eliminates considerable measuring, matching, shaping and trimming in the sewing room. Proper punching of holes and notching is important for accurately locating parts.
Quality inspection process in marker making: Locations with manual marker making system: In these locations, the markers should be inspected by the Quality Control Department before the fabric is laid. This will leave sufficient time to make any correction to the marker that is necessary.
Locations with computer marker making (CAD) system: In location that uses the CAD system, the marker information needs to be cross-checked by an operator other than one who complied the marker, before the marker is printed. This is to ensure that no operator error has occurred. The marker can then be re-inspected by the Quality Control Department after it has been placed on the lay of fabric prior to cutting.
