I'm looking for some advice please.
I have a few hundred pages to photocopy and I need to anonymise the text by blanking out names. I thought I would do it like this:
(1) photocopy the document (2) use a black marker pen on chosen parts of text (3) photocopy the marked page
Unfortunately, unless the marker ink is the same type of "black" and is very opaque then the photocopy can sometimes pick up slivers of lines which formed letters in the original text. This could depend on which copier is used and if it needs a service. So it's not really good enough.
One idea I had was to use a narrow black tape maybe 5 or 6 mm wide over the text.
If I needed to get such tape then where could I get it? Ideally it would be easy to tear so I could work through these documents quickly. Maybe a paper tape rather than vinyl plastic.
Are there other effective but quick ways you have come across?
