Saving fading documents (wa Fading T(h)ermal Paper)

Discussion in 'Photoshop' started by Norman H. West, Jul 11, 2005.

  1. Reviewing first responses to my query, it is obvious I did a poor job
    explaining what I was trying to do.

    I have documents printed on light sensitive paper such as used on a
    fax, etc on which the printing is gradually disappearing. The
    printing is so faint that things like OCR are not an option.

    I have scanned the document into Photoshop and tried things like
    level adjustment, selection by color, etc. and have come to the
    conclusion that I am wandering around rather aimlessly without
    a methodical and organized approach.

    Since fading printing due to printing process, paper or age has to be
    a common problem, does anyone know of a turtorial on how to approach
    the problem in a systematic way?

    I will appreciate any help I get.

    Have all parts faded equally? Are the edges of the letters faded more than
    the center? What happens when you use Layers>Threshold?

    If I understand you in the correct way, this problem shouldn't be very hard
    to solve. The problem is, that you might not get me right, because I use the
    German version of Photoshop CS. In German you choose
    Bild-->Anpassen-->Schwellenwert. Here you can choose the "Schwelle" between
    black and white and you see the result in the preview. If your documents are
    only containing black and white, this should be a good way to make them read
    after exporting by an OCR. If you want to convert more than one scan in this
    way you can make an "Aktion" and use the "Batch-Conversion-Modus".

    If you need more help I can send you a picture from the steps I've explained
    above. It is only in German because of the German version, but the buttons
    in the English-Version should work the same way than mine.
