LESSON 8&9 (4) : Grading
Objectives
At the end of this lesson, you will be able to:
• explain about the grading
Digitizer Settings
Pattern grading can be defined as the process of increasing or decreasing / enlarge or returning from one size to
another proportionally. The main advantages of pattern grading is “Time saving”.
For example in a garment industry, one person is consuming 4 has each for preparing pattern for 4 no of sizes
(1 hrs each) and he has to spend 16 Hrs. For the whole process. But, with the help of grading he can complete
the entire process with in 8 hrs and he can save 8 hrs. First he can prepare the pattern for one size with in 4 hrs,
and then with the help of grading he can prepare the remaining pattern within 4 hours. After preparing a pattern
the outlines of the pattern has been enlarged or reduced with the help of “increments” of the measurement chart
during the grading process.
This has been illustrated in the following simple Fig 1
Fig 1
Pattern grading process requires size interval and increments of a measurement chart.
Size Interval
It can be defined as the amount by which a measurement varies from one size to another size.
E.g
Size S M L
Chest 80 Cms 84 Cms 88 Cms
Here the size interval of chest measurement
S to M = 84 – 80 = 4cms
M to L =88 – 84 = 4cms
Increment
It can be defined as the amount by which a variable quantity varies from one size to another size .
