Marker has two dimensions
i. Marker width
Markers are made to fit the cuttable widths of fabrics. Cutable width is the usable portion of fabric width. Salvage are often not usable When fabric width is grossly inconsistent, fabric in a lot may be grouped by width and different marker produced for each width. Using the extra width in planning markers can save significant yardage or prevent recuts when fabric is narrower than ordered. Marker may be produced in section or block or be continuous.
ii. Marker Length
A marker is made for a specific style, fabric, and number of sizes. The length of the marker determines the length of the lay that will be spread. Marker may be produced in sections or blocks or be continuous.
1. Block or Sectional Marker
Blocked or sectioned markers contain all of the pattern pieces for one style in one or two sizes. Sections may be used separately or joined together to form an extended multi-size marker. Blocked or sectioned markers are easier to visualize, plot, and handle, but they may not produce the best utilization of fabric.
Sectioned markers may be used to adjust the volume requirements for various sizes or as a remnant marker. It is also advantageous if there is end –to- end shade variations of the fabric. A stepped spread for a sectioned marker may consist of plies of varied length, spread at different heights.
2. Continuous marker
Continuous markers contain all the pattern piece for all the sizes including in a single cutting. They may be lengthily and often required more juggling of pattern piece. Pattern piece are grouped by size shape rather than by garment size. Continuous marker often have better utilization because there is more flexibility in grouping and maneuvering large pieces and small pieces.
3. Splice Marks
Splice Marks are planned into continuous markers to avoid excessive fabric wastage and incomplete pieces. Splice marks are points in marker where fabrics can be cut and the next piece overlapped to maintain a continuous spread. Splice marks may be one inch or several inches depending on the overlap needed to accommodate the pattern pieces in the area of the splice. A rectangular box indicates the amount of overlap needed.
Splice marks are inherent when markers are planned in blocks. Piece goods may be spliced at any point where the sections of a marker are joined together. Splices are needed when flaws are removed, a roll change is made, or a short length of fabric is used.
