Abstract: A printer for printing an image onto a substrate includes a thermal print head having a plurality of electrical resistors, a supply of coloring material adjacent the print head for deposition on the substrate and a print head controller. The print head controller provides a pulse train output to at least one of the electrical resistors. The pulse train includes a plurality of pulses and at least one pulse has a variable width related to a binary value at least another pulse has fixed width.

Abstract: A printer is provided with a smart card encoding device that is externally accessible. The smart card is a key with an integrated circuit including a memory that will retain a discrete password and other digital information. The password on the smart card key must be compared to a password stored in the printer memory before printing operations will be permitted. The digital information in the smart card key memory can include marks or graphics that would indicate that the cards being printed by the printer are secured cards and authorized cards. The information will be printed from the smart card key memory only when the passwords match so that the discrete information on the smart card key can be used for driving the printer for printing this information. The printer is made into a high security printer by permitting the overriding of the password only upon the generating of identical numbers from separated algorithms, one in the printer memory and one at a secure location.

Abstract: The present invention provides a method of performing a burn cycle in a thermal printer that reduces printhead switching while increasing printing speed and extending printhead life. In the method, data is loaded into a shift register of a thermal printhead to designate resistive elements that are to be enabled and disabled during the burn cycle. Next, the data is latched into a burn register of the printhead and a power supply of the printhead is activated thereby energizing the enabled resistive elements. New data is then loaded into the shift register. After a short burn period has expired, the new data is latched into the burn register. The steps of loading and latching new data are repeated a predetermined number of times, after which the power supply is deactivated to complete the burn cycle.

Abstract: A label for a component is provided with a continuous color tone background at least in segments of the label that can be detected as to a configuration using selected colored light sources which reflect from the different color tones of the label. A sensor can be used for discriminating between the reflection patterns from the light sources. A continuous color tone on the label changing smoothly from one color to others is applied to make a uniform shading from one color at one end of the label to another color at a second end, with various colors between the two ends. As an added feature, a number of black appearing strips forming a bar code can be provided on the label, with some of the strips reflecting infrared light and others not reflecting infrared light, so an infrared detector can be utilized for determining the pattern of the bar code for further identification of the labeled component. The bar code pattern will not be identifiable with the naked eye.

Abstract: A printer for printing information on images on a substrate such as an identification card in multiple colors has an intermediate transfer film or web on which a reverse image is printed. The printer has a lamination station where the image is transferred to a substrate, such as an identification card. The intermediate transfer film or web is moved back and forth, the intermediate transfer film or web has slack occurring in it between the printing station and the lamination station. The slack is taken up with spring loaded rollers to permit operation of the printer head and the lamination station at the same time. Additionally, the printer is made into modules that are movable for easy access to interior components and to expose film or web paths that permits installing both the print film or web and the intermediate transfer film or web without threading it through enclosed openings.

Abstract: Information is printed onto an identification card using an ink jet printer. The ink jet printer includes a tray which moves the card in a first direction and a print head which moves relative to the card in a second direction. An ink receiving surface may be deposited onto the card prior to ink jet printing. A magnetic recording head is optionally included in the printer whereby information may be magnetically recorded onto the card.

Abstract: The printer is adapted to print an image onto a substrate using a web carrying a color material. The printer includes a web supply configured to supply the web and a web take-up configured to receive the web. A print head is configured to material from the web to the substrate. A controller provides a control signal to the web take-up or web supply as a function of heat energy applied to the web.

Abstract: A method for printing an identification card includes printing an image on a surface of the identification card and depositing a first overlayer onto the surface of the identification card. Ridges are created in the first overlayer. A second overlaminate layer is deposited over the first overlayer. The second overlaminate layer includes ridges created by the ridges in the first overlayer such that the ridges create a visible pattern on the identification card.

Abstract: An identification card processor receives cards from a hopper, and passes them through a graphic imager for printing, and either prior to printing or subsequently the cards are positioned on an index table that permits moving the cards about an axis to different positions for further operations. The further operations take place at locations set off from the plane of movement of the cards in the graphics imager to conserve space. The indexing table is capable of being indexed to any desired rotational position in a full 360.degree. of movement, and for moving a card under positive drive to and from the index table.

Abstract: A detector assembly for detecting registration marks on a printed sheet when different color printing on different colored sheets is present has a pair of light sources and a light sensor. The light sources are of different colors selected to be complimentary such that one light source or the other will be capable of detecting a substantial range of contrasting registration marks placed on sheets that can be of various colors. Controls are used for selecting the light source that provides an output sensed by a light sensor when passing over the registration marks.
