1. Technical Field
The present invention relates to the automation of design extrapolation across apparel pattern pieces, wherein a design made for a pattern set at a particular size (example: Man's Size M, T-shirt) is extrapolated to other sizes of the same pattern set (example: size XS, L, XL) or to pattern sets of a different product (Example: Size M of Woman's T or to a Backpack).
2. Description of Related Art
The concept of creating custom designs on apparel has been around for a long time. As is well known in this field, the actual size of the apparel can vary widely from one size to another (a Men's T-shirt, for example, varies by as much as 16 inches in width from XS to 2XL). This is not a problem if the design is only on the front or the back—one can just leave the additional area blank, but is a problem when the design spans seams (full-bleed designs). To make matters more complex, most apparel grow much more horizontally, than vertically across sizes and scye curvature also varies with size. For example, from XS to 2XL, the width may increase by as much as 16 inches, but the height only by 4 inches.
Therefore, a direct scaling of image will cause it to lose aspect ratio and make the image look “squished” and in cases get parts of the design, image or texts cut-off, necessitating the designers or consumers to design individually for each size they need, in what is today, a largely manual process.
