Introduction:
Every marker maker wants to plan marker with highest efficiency to confirm the highest use of fabrics during apparel production but it is always not possible to place the pattern pieces as desired place. This occurs because during marker planning, marker maker have to maintain some requirements.
Constraints of Marker Making:
The limitations for which marker maker cannot plan marker as desired are as-
- Grain Line
- Design of Garments
- Nature of the Fabric
- Cutting Accuracy
- Production Planning
The hinders or constraints of marker making are described here:
1. Grain Line: Grain line is a more effective constraint of marker making because of grain line sometimes it is tough to place the pattern pieces onto the marker, even though it is possible the wastage becomes higher.
2. Design of Garments: Sometimes the designs and repeats of the fabric are regarded as constraints of marker making. The patterns may miss the designs or may overlap the designs.
3. Nature of the Fabric: Nature of the fabric may sometimes be regarded as a constraint of marker making. Nature of the fabric includes symmetric and asymmetric.
4. Cutting Accuracy: Accurate cutting may be one of the constraints of marker making.
- During cutting the edge of cutting knife blade requires sufficient space so that it can be moved in desired direction. So that the pattern pieces should be arranged with a little space among themselves. Otherwise, it may reduce marker efficiency.
- Pattern pieces for a particular order should be counted carefully to ensure that no parts have been missed to be included as well as to ensure that no parts have been included twice unnecessarily.
5. Production Planning: Production planning includes rate of production, types of garments, sizes of garments, etc.
Suppose we have order of 3000 pieces for the four sizes like S, M, L, and XL.
Where, S = 600 pieces, M = 1200 pieces, L = 600 pieces, and L = 600 pieces. Fabric thickness constraints the number of plies in the lay to 150 only. Then size ratio will be:
600 : 1200 : 600 : 600
= 4 : 8 : 4 : 4
Total 20 sets of patterns will be included in the marker. It would be a long marker obviously so in that case marker efficiency will be higher; but it will require more time, bigger sized table, more lays of fabric from different rolls which can increase the possibility of shade variation.
Therefore, we can produce two markers without altering the size ratio and two relatively short markers would be produced.
First marker = 2 : 4 : 2 : 2 (10 sets of patterns in the marker)
Second marker = 2 : 4 : 2 : 2 (10 sets of patterns in the marker)
