ABSTRACT:
Text (indicia, words, symbols, etc.) of documents is highlighted in such a way that it will reproduce when electronically copied (e.g. photocopied or telecopied). This is accomplished by applying a tone to only that area of the document to be highlighted and so that the tone remains in place during copying. The tone is sufficiently dark so as to highlight the text, but light enough so that the text is readable. The tone may be a dot or line screened tone having about 30-65 lines per inch with a density of about 10-22%. The tone may be applied on adhesive tape and just placed over the document portions to be highlighted. The tape may be dispensed from a dispenser. Alternatively, the tone may be on a transfer sheet, and is transferred to the document merely by the act of rubbing on the transfer sheet. The tone may also be applied to the document utilizing a print wheel in a casing, that is moved over the document. After the document is electronically copied (e.g. by a photocopier or a facsimile machine, for example) the document is highlighted yet the text is clearly legible.
