Development of Resizing Software for Paper Patterns

Today, with the advancement of technology and practical tools, the use of manual methods has become inefficient due to time consuming. The keys to success in clothing production are the correct use of modern tools, new methods of design and production management. In the present study, an attempt was made to provide a fast and accurate method for converting a paper pattern to a modifiable and sizable digital pattern using image processing that is easily accessible and is not required special knowledge. In addition, different types of patterns including female upper body pattern, collar and collar hem, sleeves and pants were prepared. In order to express the results, six levels are considered for the average error obtained from sizing, which are high level (error less than 0.1 cm), relatively high (error between 0.1 cm to 0.4 cm), medium (error between 0.4 cm to 0.6 cm), relatively medium (error between 0.6 cm to 0.8 cm), relatively low (error between 0.8 to 1 cm) and low (error greater than 1 cm). After sizing and evaluating the measured errors, it was concluded that the average total errors in the proposed method to increase and decrease the sizes are 0.33 and 0.266 cm, respectively.
