Marker markings are layouts of pattern pieces for the purpose of cutting. Great effort is made to arrange patterns in the most material economizing manner, within the constraints of fabric type, width, and fabric designs.
And marker makings are the actual full size print[print?:printing image graphic cutting solution] out of how the styles are cut on the fabric. The cost of pattern grading is incomplete without considering marker making.
Computer can draw a marker making in very little time since most of the work was done in the grading process. The greatest benefit of marker making is convenience. A designer only needs to order a marker marking made to fabric width.
