IMD does have its challenges and limitations. Therefore, up-front design considerations are of paramount importance for the process, including printing, forming tool, cutting tool and injection molding tool design. In particular, graphic locations may need to be printed distorted before the forming operation to allow the graphics to move into register during the forming process. While not recommended, some existing tools can be modified for IMD. However, new tooling is almost always recommended.
Some graphics such as concentric circles, long lines and parallel lines should be avoided because of the unavoidable distortion induced by the IMD process.
Some shape limitations.
