Accuracy is a major factor in marker quality. Complete data and precise lines are essential for cutters and sewers to process the garment parts correctly. Information needed for each pattern piece includes size, style number, and piece name or number line must be accurate, consistent, fine, smooth, and a precise image of production pattern. Computerized marker making is more precise and eliminates mistakes that occur with hand-drawn markers. CAD systems areas for a firm to invest in technology because of the time say- they provide. Lines are always consistent, pieces are not omit- always on grain and facing the designated direction unless an is used.
Depending on quality standards, pieces may be overlapped slightly or have corners rounded in an effort to conserve fabric. These economies frequently cause problems when operators try to align two corresponding pieces for sewing.
The omission of even the smallest piece from the marker can create major problems and re-cutting. A missing piece may not become apparent until the garment parts are prepared for sewing. By this time, it is difficult to find the specific pattern piece and identical fabric to re-cut the piece. Scraps may have been discarded, or remaining fabric may be a different dye lot. If the fabric can be found, special handling and separate cutting are required. This is a common problem with manually made markers.
Planning the knife path for cutting is an important quality consideration. There must be space for the cutting knife to maneuver without cutting into adjoining pieces. It is easy to cut straight into a lay but to turn and change directions requires space in the marker where this can happen without damaging other pieces. If manually cut, consideration must be given to the position of the cutting operator because operators are not able to maneuver as freely as a computer-controlled knife.
