Anyone know if there's any kind of eraser to erase ink from printed
paper, not liquid based, but a dry one,
or any ideas on how to remove ink from a printed paper?
thanks!

Curious. Why?

Lou
Curiosity killed the cat. Satisfaction brought it back.
 
I know of no eraser for ink from paper. The idea is that the ink
penetrates the paper to stay there, either via a microporous paper which
allows the ink molecules or pigment through the surface into a substrate
or swellable polymer, in which case the ink is integrated into the
polymer while wet and becomes encapsulated into it. Either way it is
not designed to let go other than with strong oxidizers like bleaches or
water which rehydrates the polymer. Either way would do major damage to
the image, the paper surface, or more.

Sorry, the only way to remove a spouse from all the family pics is to
use a scissors ;-)

As Art says, there is no way to do this because of the way that paper and ink
interract.
I note that you say no to a liquid based means; but if the original is text
only you could carefully cover the part of the text you don't want with liquid
paper and photocopy the result. With very great care you may be able to do this
with an image also depending on whether the photocopying is going to have high
enough quality for you.

Some check artist were using bleach or amonia to remove the written info on
a check to get a check with just the company printing on it
and then could rewrite it for their purpose
The news did not go into lots of detail..

Not true. We don't know a dry process, but we do know a wet one that works
for "may" scenarios. The trouble is, to post something like this delivers
the information to those who might use it for harmful purposes.

Which comes back to my first post (to the OP right after he put up the OP)
Why???

Lou
Like the old saying goes, "when a guy with experience meets a guy with
money, the guy with the experience gets the money and the guy with the
money gets experience."
 
Some formulations of ball point pen ink will bleach out with chorine
bleach, and some will dissolve out with certain solevnts, like acetone,
but inkjet inks are a bit different.

I really can't believe that you think that a piece of simple information that
almost anybody could have worked out for themselves is dangerous.
We will be banning the sale of motor vehicles next because they can be used as
get away cars or banning the sale of household detergents because they can be
used to poison someone!
I can think of many reasons why someone would want to do what the poster wants
and nearly all of those things are legal and reasonable.

Not only that, but where does one think the best,
simplest information on how to remove ink from
paper comes? Forgers and counterfeiters likely
know and use the best procedures. Want to know
how do something easily and cheaply? Ask a crook!
Keeping information out of the bad boys hands is
silly, they probably produced the info.

Uh, but people still lock the doors to their homes and cars.
The idea is to make it a little harder for those contemplating bad things.

Depends on both the paper and the type of ink. If it's a book then the
existing text will be probably carbon black based, if the ink is
coloured, then it's probably dye based. Dye based inks fade under
UV light, carbon black doesn't. So, although suitable UV sources are
rather specialised discharge tubes, based on quartz envelopes, it
might be possible to selectively fade a dye based coloured ink.
Such sources also generate a significant amount of Ozone, itself
an active fading agent.
It is not possible to give advice without further information
about the paper and ink. Paper is a very broad term, book, newspaper, bond,
laid, coated, there is an extensive list, all with their individual
characteristics, often tailored to specific applications, like banknote
paper. Perhaps that is what he is interested in, he has a load of brightly
coloured bank notes.
Having specialised in the shorter, more photo active end
of the UV spectrum, some colours, and coloured plastics, can be bleached
in a few days, with a high enough intensity, of the right wavelength.
One could of course generate the UV in a vacuum chamber and
enclose the paper in it, thereby getting rid of the absorbtion
of the quartz envelope, a problem as you move further into the
extreme UV.

Locking doors has nothing to do with providing
information.

That may be the idea and such thoughts are often
projected by people with good intentions.
However, the bad guys already no more about these
things than most law abiding people.
 
good tip thanks
