Pattern Grading by Computer

The first computers designed for pattern grading were introduced in the U.K during the 1960s.Their field of operation was limited for pattern grading only,which was inadequate for the needs of the clothing industry.The latest models today can preform a variety of extra task such as lay-marker making,miniature scale patterns for lay planning,and estimates on fabric utilisation based on the area and peripheral measurements of the complete pattern.In short ,any operation connected with pattern and marker making can be performed by a computer at a price.

The first phase in the preparation for grading is carried out by a  skilled pattern grader,in the preparation for grading,the programmer must decide on the correct grading technique required for each style.A single error would be reproduced on all pattern;so when we  refer to the accuracy of a computer,we mean only consistent repeatability in pattern grading.It is clear that a computer service must take care to retain only highly skilled pattern graders on its staff.
