Abstract: The present invention provides a method for a customer to interact with a computer system over a computer network for specifying custom decoration of a plastic food service article. A computer-assisted decorating machine then processes the customer input and customizes the food service article according to the customer input. Thereafter, the customized article is delivered to the customer. Creation of customized and/or personalized designs is rendered feasible by providing readymade templates for a variety of events and occasions. In embodiments, the computer-assisted decorating machine is a laser marking system, and the food service articles are made from a plastic material that discolors when irradiated with a laser beam. The markings can emulate silver, gold, or pewter without applying metals, inks, or coatings to the plastic articles, and laser marked plate products can resemble decorated china plates or other permanent ware articles.

Abstract: A plastic food service article bearing a decorative mark or image and method therefor is disclosed. The method includes providing an article made from a colored plastic such as polystyrene, polypropylene, polyethylene, PET, PLA, ABS, etc., that discolors when irradiated with a laser beam; applying a laser beam to cause localized surface discoloration; and controlling the deflection and amplitude of the beam to form a surface decoration and/or image. In embodiments, the laser is a YAG or Fiber laser, the markings emulate silver or gold or pewter without applying metals, inks, or coatings to the plastic articles. The markings are clearly visible against both light and dark backgrounds, and can be placed in food-contact areas of the articles. The technique can be used for marking customized and personalized designs, images, and photographs on food service articles. Embodiments can be used to decorate plates and/or cutlery.
