Accomplishments
· Interfaced to more imaging devices—over two hundred models—than any other individual anywhere.
o Imagesetters and Platesetters by Agfa, Creo, Scitex, Cymbolic Sciences, ECRM, Fuji, Gerber, Heidelberg, Komori, Linotype-Hell, Misomex, Optronics, Presstek, Purup-Eskofot, Dainippon Screen, Strobbe, and Varityper.
o Plotters by Canon, Epson, Hewlett Packard, Tekgraph, Iris, and TechSage.
o Dot proofers by Kodak, Polaroid, and Dainippon Screen.
o Digital presses by Hewlett Packard, Xerox, Fuji, and Landa.
· Interfaces include standard types such as SCSI and TCP/IP as well as custom hardware boards I designed. These include communication via SCSI, RS-485, RS-232, and TAXI. Hardware boards plug into PC slots of types: ISA, EISA, PCI, and PCIe.
· Designed and implemented many software and hardware features and user interfaces for the prepress market.
o Screening—traditional, stochastic, second order stochastic, and error diffusion. Use of different screening for different page elements.
o Preflight PDF checking and fixing using Callas PdfEngine.
o Image manipulation using proprietary patented image format—CTR. Manipulation includes rotation, clipping, changing resolution, antialiasing, bicubic interpolation, ICC profiling, imposing and deimposing, adding bleeds and creep, adding guides, adding annotations, extracting dielines, and many other features.
o XML manipulation.
o JMS messaging using ActiveMQ and JSON.
o Linearization editor—a UI application that includes graphing written in Java.
o Color Library Editor—a UI application written in Java.
o Various UI applications written in C++.
o Wrote one Windows drivers and debugged another.
o Made an imaging application run under Windows as if Windows was a real time operating system to guarantee data delivery without interruption.
o Wrote TCP/IP transmitter and receiver applications.
o Used many APIs for various purposes.
o Designed custom hardware to allow a single PC to continuously manipulate and deliver 192 gigabits per second of nonstop data to a digital press. This system was never commercialized, though a version using NVIDIA GPU hardware was implemented to continuously manipulate and deliver 24 gigabits per second of image data. Manipulation includes global linearization, redundant print nozzle selection, position dependent intensity correction, changing resolution, multilevel dot creation, and possible color correction.
o Developed strong relationships with hardware vendors Altera and PLX. Identified bugs in Altera chips and software, and identified and fixed a bug relating to multiprocessor SpinLock in PLX’s Windows driver.
o With others, developed and extended patented method of lossless image compression optimized for prepress applications. Implemented decompression in hardware and software.
o Designed and implemented a hardware board test system used by manufacturing, and wrote a hardware board test application used by customers.
o Designed twenty hardware boards used to interface to imaging devices. The first board, circa 1990, ran with a 10 MHz clock. The latest ran at 100 MHz externally with a 250 MHz internal FPGA clock and a 1 GHz DDR3 clock.
o Performed purchasing, supervised contract manufacturing, developed industry relationships, designed hardware, and wrote software too numerous to recount.
· Designed and coded user interfaces in C++, Java, and C#. Read from and modified data in SQL databases.
· Technical writing.
