摘要:
A method of reducing uneven use of the total number of printing elements on a print head in a printer, when selectively using the printing elements to make different size color image prints on respective similar size receiver mediums, comprises: selectively using the total number of printing elements to make color image prints substantially the same size as the receiver mediums; and selectively using a particular number of printing elements less than the total number of printing elements to make similar size color image prints smaller than the receiver mediums, but alternating which ones of the total number of printing elements can be selectively used to make each print so that the placement of each print on a receiver medium is alternated, whereby, since those printing elements that can be selectively used to make each print smaller than a receiver medium are alternated, uneven use of the printing elements is reduced.

A method of reducing uneven use of a series of heating elements a color image print smaller than the size of the receiver medium and leave a non-image non-color margin area along at least one side of the color image print; and using other ones of the heating elements to effect yellow, magenta and cyan dye transfers superimposed on a non-image non-color margin area left along at least one side of the color image print to make the margin area a shade of substantially gray or black, whereby, since those heating elements which are not to be selectively used to effect the dye transfers to create the color image print are instead used to effect the dye transfers to make a non-image non-color margin area left along at least one side of the color image print a shade of substantially gray or black, uneven use of the heating elements on the print head is reduced.

A roll-fed duplex thermal printing system, comprising a supply roll of receiver media, a printing path, a reversing path, a diverter and a cutter positioned between the diverter and the reversing path. When the diverter is in a first position the receiver media is directed from the supply roll or the reversing path into the printing path. When the diverter is in a second position the receiver media is directed from the supply roll into the reversing path. During a printing operation, the diverter is positioned in the first position and the receiver media is fed into the printing path where a first side image is printed. The diverter is then repositioned the receiver media is fed into the reversing path where it is cut. The diverter is then repositioned again and the receiver media is fed into the printing path where a second side image is printed.

Observable matte-finish indicia on a printer medium having a matte finish includes the steps creating a matte image-viewing area; creating a glossy finish region within the image-viewing area; creating indicia having a matte finish within the glossy region. The printing medium has a dye-receiving element; and the steps of controlling the specularity of the image-viewing area, the glossy region, and the indicia include the step of imagewise-heating a donor element comprising a support having thereon a laminating patch of overcoat material, the donor being in contact with the dye-receiving element to thereby thermally transfer a layer of overcoat material to the printing medium, the overcoat material layer being transferred using a predetermined energy level within the image-viewing area and the indicia in order to create a matte finish and using a different energy level within the glossy region to create a gloss finish.

A thermal printer having reduced electrical charge built at point of separation of a donor web and a receiver web, includes at least one thermal printhead and at least one platen roller with a nip is formed between the at least one thermal printhead and the at least one platen roller through which the donor web and the receiver web are drawn. A heat sink is attached to the at least one thermal printhead and a peel member is located downstream of the nip. The peel member is substantially electrically isolated from ground.

An adapter is provided for use with a supply spool having first and second spool ends the spool having web media thereon. The adapter has a body having first and second body ends with each of the first and second body ends having shaped linkages to join to one of the first and second supply ends and with each body end further shaped to join to a printer receptacle when not joined to a spool end; and a data source. The body shaped to position the data source relative to the first body end so that when the first body end is joined to a first spool end, the data source is positioned to provide the machine readable data so that the machine readable data can be read by a reader in a printer that is adapted to accept a supply spool having web media that is axially located asymmetrically.

Methods and control systems are provided for operating a thermal printer adapted to print images by heating and transferring donor material from donor patch sets from onto a receiver medium, the printer being operable to print images in a manner that exhausts a full donor patch set or a fractional donor patch set during printing. The control system comprises a controller for identifying one of the donor patch sets on the web as a fractional donor patch set having sufficient donor material remaining to print an image. The controller is further adapted to determine that the fractional donor patch set is not to be used for printing when the identified fractional donor patch set has been used to print an image wherein at least a minimum area of at least one donor patch has been heated to a level above a threshold level.

This invention relates to a method for transferring a protective overcoat for a thermal print wherein the protective overcoat is applied to a dye-donor element under predesigned conditions after thermal dye transfer, the dye-donor element comprising patches of dye for transfer to a thermal print to provide a protective layer thereon. In particular, the invention improves the process of providing an improved level of gloss to the transferred protective overcoat. The method involves a preselected duration between printing and peeling the transferable laminate patch, respectively, to and from the donor. The invention is particularly advantageous at lower line times, faster printing, for thermal prints with high gloss.

An adapter for a spool includes a body having a first body portion and a second body portion that are slidably joined together. The first and second body portions are slidably adjustable to each other. The first body portion includes a first contact surface and a second contact surface comprising at least one projection adaptable for joining to the spool.
