Abstract
What is disclosed is a system for registering an object in a direct-to-object print system and a direct-to-object print system configured to operatively use various embodiments of the registration system of the present invention. In one embodiment, the marking system comprises a registration panel with a plurality of registration markings. A camera captures an image of the object in the object holder and the registration panel. A processor receives the image and analyzes the image to determine a position of the object relative to the markings on the registration panel. The processor determines whether the object is registered. If the object is registered, a controller causes the object holder to move the object past the printhead. Otherwise, if the object is not properly registered then the processor prevents the object from being printed and communicates a notification to a user that the object in the object holder is not registered.

DETAILED DESCRIPTION
[0017] What is disclosed is a system for registering an object in a direct-to-object print system and a direct-to-object print system configured to operatively use various embodiments of the registration system of the present invention.
Non-Limiting Definitions
[0018] An object has at least one surface thereof to be printed. Example objects are sports equipment and paraphernalia, golf clubs and golf balls, commemorative gifts, mugs and coffee cups, to name a few.
[0019] A direct-to-object print system or simply print system is a printer designed to print on a surface of an object. The direct-to-object print system of
[0020] A printhead or print head is an element (such as an inkjet) which emits or ejects a droplet of marking material such as ink on to a surface of an object thereby making a mark on that object. In one embodiment, the direct-to-object print system has a plurality of monochrome printheads and a UV cure lamp. The print zone is a width of a single M-series printhead (4 inches). Each printhead is fluidly connected to a supply of marking material (not shown). Some or all of the printheads may be connected to the same supply. Each printhead can be connected to its own supply so each printhead ejects a different marking material. A 101 array of printheads is shown at 104 of
[0021] A support member, at 106 of
[0022] An actuator, at 110 of
[0023] An object holder, at 112 of
[0024] A registration panel, at 113, of
[0025] A controller, at 114 of
[0026] A user interface, at 118 of
[0027] An identification tag, at 126 of
[0028] A sensor, at 128 of
[0029] A camera, at 130 of
[0030] A storage device, at 134 of
[0031] Receive an image is also intended to be widely construed and includes retrieving, capturing, acquiring, or otherwise obtaining images. The image can be received or retrieved from a remote device over a network, or from a media such as a CDROM or DVD. The image may be received directly from a memory or storage device of the camera used to capture that image.
[0032] Registered means that the object is positioned in the object holder so that when the object holder moves the object past the printhead, the mark to be printed on the object is properly placed and that the object comes within a pre-defined distance to the printhead (called the print zone). When the object is in the print zone, droplets of marking material ejected from the printhead form the mark on the object with a desired level of image quality as determined by a user, operator, or technician.
[0033] It should be appreciated that various operative steps such as: receive, retrieve, perform, determine, cause, analyze, communicate, prevent, and the like, as used herein, include the application of any of a variety of techniques as well as mathematical operations according to any specific context or for any specific purpose. It should be appreciated that such steps may be facilitated or otherwise effectuated by a microprocessor executing machine readable program instructions such that the intended functionality is effectively performed.
