Abstract: A method of manufacturing a polyolefin product is disclosed. The method includes the steps of printing an image on a transfer medium, hot pressing a carrier medium (such as a textile or wood product) and the transfer medium such that the image is transferred to the carrier medium, and adhering the carrier medium to a first polyolefin article to produce a polyolefin product. The polyolefin product may then be subject to further processes, such as cutting, thermoforming, etc. into its desired form. An improved method of producing polyolefin products having colorful imagery thereon is provided. A method of manufacturing a case is also disclosed, including printing an image on a transfer medium, hot pressing a carrier medium and the transfer medium such that the image is transferred to a first side of the carrier medium, and assembling a case, wherein a panel for the case includes the carrier medium.
