Peter Heath patents

Recent bibliographic sampling of Peter Heath patents listed/published in the public domain by the USPTO (USPTO Patent Application #,Title):



12/04/14 - 20140354726 - Multi-layer printing on non-white backgrounds
In a multi-layer printer, the base white layer that is applied during printing is modified using the image to be printed. By altering the white layer to reflect the density of the top image, it is easier to reach saturation (density/gamut) without adding large amounts of ink. Thus, such undesirable...
Inventors: Peter Heath, Dwight Cram, Bryan Ko, Joseph A. Lahut

10/09/14 - 20140300658 - Inkjet printer with dot alignment vision system
unidirectional, bidirectional, and step alignments; physical position and straightness of jet packs; flatness of platen or media belt; mapping imperfections in rods and rails of guiding systems; and checking jet alignments from a reference jet to all other jet packs. From such image analysis, correction values are generated that are...
Inventors: Luis Alejandro Jimenez, Peter Heath

10/17/13 - 20130271549 - Method and apparatus for thermal expansion based print head alignment
Automated print head alignment uses thermal expansion. By leveraging thermal expansion to position print heads within the carriage, the tedious manual adjustment process is eliminated. The need for costly precision references within the printer and on the print head is also reduced....
Inventors: Peter Heath

09/26/13 - 20130250001 - Reduced gloss banding through low ink volume deposition per print pass
Improved output quality of a printer used in UV curable ink jet printing is achieved by minimizing or eliminating a print artifact referred to as gloss banding or tire tracking. A same or a similar number of nozzles as used in conventional printers is used to achieve a desired throughput,...
Inventors: Joseph A. Lahut, Dwight Cram, John Duffield, Peter Heath (Electronics For Imaging, Inc.)

05/23/13 - 20130127971 - Method and apparatus for thermal expansion based print head alignment
Automated print head alignment uses thermal expansion. By leveraging thermal expansion to position print heads within the carriage, the tedious manual adjustment process is eliminated. The need for costly precision references within the printer and on the print head is also reduced....
Inventors: Peter Heath

02/28/13 - 20130050368 - Ink jet uv pinning for control of gloss
Gloss is controlled in UV ink jet printing within a printing system. Controlled pinning energy is used to adjust the amount of ink interaction between drops, substrate, and ink layers, resulting in virtual elimination of gloss banding and control of the finished gloss level from a gloss level of approximately...
Inventors: Joseph A. Lahut, Dwight Cram, John Duffield, Peter Heath

12/13/12 - 20120313995 - Inkjet printer with dot alignment vision system
Image processing of printed patterns of arrays of dots generated by an array of inkjet heads uses a vision system, including an HD color camera that can be a fixed focus or include autofocus and zoom capabilities. Pattern recognition techniques are used to analyze as many patterns as necessary to...
Inventors: Luis Alejandro Jimenez, Peter Heath

03/15/12 - 20120062642 - Inkjet printer with dot alignment vision system
Image processing of printed patterns of arrays of dots generated by an array of inkjet heads uses a vision system, including an HD color camera that can be a fixed focus or include autofocus and zoom capabilities. Pattern recognition techniques are used to analyze as many patterns as necessary to...

09/30/10 - 20100247795 - Selective ink cure
Individually controllable ultraviolet (UV) light-emitting diodes (LEDs) are used to cure ink and generate different effects. The UV LEDs only expose specified areas to generate the different effect and can create multiple effects on the same substrate by exposing different areas to varying amounts of time or by performing a...

The bibliographic references displayed about Peter Heath's patents are for a recent sample of Peter Heath's publicly published patent applications. The inventor/author may have additional bibliographic citations listed at the USPTO.gov. FreshPatents.com is not associated or affiliated in any way with the author/inventor or the United States Patent/Trademark Office but is providing this non-comprehensive sample listing for educational and research purposes using public bibliographic data published and disseminated from the United States Patent/Trademark Office public datafeed. This information is also available for free on the USPTO.gov website. If Peter Heath filed recent patent applications under another name, spelling or location then those applications could be listed on an alternate page. If no bibliographic references are listed here, it is possible there are no recent filings or there is a technical issue with the listing--in that case, we recommend doing a search on the USPTO.gov website.
