DIGITAL GRADING AND MARKING
With our digital pattern making process we can help to speed up Product Development and Production cycle with sampling and production-ready pattern design.
Our digitally graded pattern blocks are perfected for each size and digitally checked for accuracy for each size before proceeding to final bulk production.
We provide support and instructions on how to build comprehensive technical packages with detailed construction pages and garment grading rules.
Factory production time is capitalized by using 3D virtual fit simulation and grade proportion check.
Production garment manufacturing troubleshoot will help you save the time and money on unforeseen technical and production issues.
What is pattern grading for clothing?
Pattern grading is an important part of the manufacturing process and presents the creation of size range for a specific style. During the garment development phase, the pattern is created for the sample to fit specific size (e.g. size 4 or small). The fit and style modifications are further refined on that sample size.
After the fit approval for the specific size, the pattern will be graded for a full size-range (alpha or numeric sizing).
The common practice in the apparel industry is to have specific full graded spec within the tech pack with grade rules for each listed POM (point of measure). The grade rule represents the amount of increase or decrease for each grading point on the pattern.
For example, if the bust, waist and hip measurement have 1” grade between sizes (for the full measurement), the full amount will be distributed equally at each seam of the sewing pattern (e.g. front and back pattern will be graded 1/4” at each seam).
For larger sizes grade rule will change to accommodate the different body proportion. The amount of the increase will depend on the specific brand’s fit requirement.
Grading for Alpha sizing example
Alpha sizing is commonly used for knit clothing. Physical sample measurements are recorded in the tech pack as a half measurement. Generally, grade rule for alpha sizing (e.g. bust, waist, bottom opening) is 1” for the half measurement or 2” for the full measurement.
Grading for numeric sizing example
Numeric sizing is usually applied to clothing styles made of woven fabrics or fit specific styles (e.g woven pants). The image below shows a grade rule example for a few POM-s (points of measures).
