fabric marker are reduced in size by 3 mm around all edges (see Fig. 3.10B). Blocks
with the pattern pieces of fusible components are copied to an interlining marker as
new and large size pattern pieces. These are also reduced in size by 10–12 mm around
all edges (see Fig. 3.11B).

3.9 The automated marker-making process

The speed and quality of manufacturing markers by automation are increased by the
following:

Markers are created on a computer screen in decreased sizes.
●
Additional actions reduce the requirements of the work process.
●
Markers can be created automatically using overnight processing.
●
Nesting software allows the operator to move pattern pieces on a computer screen
within a frame width equal to that of the fabric. This process may be performed au-
tomatically or semiautomatically. Markers are created for all the materials used in
production of the style: face fabric, lining, interlining, and other auxiliary materials.
These markers may be saved for later use in the cutting process or for the adaptation
of new markers.
During the marker-making process, pattern pieces can be copied, rotated, dupli-
cated, flipped, displayed, split, etc. while remaining in the correct orientation to the
thread direction or fabric grain. Depending on the qualities of the fabric being used, a
particular size of buffer is placed between the pattern pieces.
