    Thumbs down HP Large Format Photo Negative Application

    Has anyone looked into the work regarding the making of large negatives using HP printers - I bumped into the following articles when trying to do some research about using the Epson 2400 printer to convert digital photographs into large negatives to do platinum prints :

    Even though these are talking about using a $4000 printer to produce the negatives, it is certainly a new wrinkle to research (nice alliteration).

    Any thoughts?

    I have an HP 4000 Laserjet with 100MB of printer RAM. It can print 8X10 at 1200 DPI. I tried making some negatives on laser transparency film. I figured I could make 16X20s at 600 DPI from them, but they were too flat. Definitely not what you want for platinum printing. For the right subject matter, the HP 4000 (which can be purchased quite reasonably used) does make a nice B&W print on watercolor rag paper that has an almost platinum look to it.

    I'm sorry, but what does it have in common with the HP Designjet Z3200 Photo Printer (subject of the article) beside the HP logo?

    Re: HP Large Format Photo Negative Application

    "Over the past decade, specialist printmakers have
    been struggling with the process to produce largeformat
    negatives for platinum prints. The crucial
    element that has persistently eluded them is easy
    and reliable control over tone and contrast. But
    that control has now finally been achieved with
    the new Large Format Photo Negative application
    from HP. Erwitt was privy to this new solution before
    official release and has produced platinum prints.
    HP was lucky. One of its color scientists, Angel
    Albarran, who is a photographer with a passion
    for alternative printing processes, discovered that
    green Original HP Photo Ink just happens to have
    a very linear response to ultraviolet light. As the
    density of this green ink on a negative increases,
    the amount of light that makes it through to the
    coated paper decreases in a very predictable way.
    Albarran developed the Large Format Photo Negative
    application to exploit this linear response, providing
    accurate differentiation among tones right through
    the grayscale spectrum. The result is that well-defined
    details automatically show up in shadows, mid-tones
    and highlights, and there’s also a clean white on
    the final prints. Printmakers can now forget about
    digital tone adjustments before printing, unless they
    particularly want to darken or lighten part of the
    original image. "

    It seems that there is a new way to look at how to produce the large negatives for our platinum prints.
