No, not exactly but it may come in the future!
The image is printed on the swell paper which then has to be fed through a
special machine with heat/light tubes to swell the image by heating the
microcapsules of alcohol contained in the paper coating.  The temperature
has to be controlled according to how dense the blackness is.  More black -
less heat. Large areas of black should be printed in fine black/white
stripes to avoid overheating and therefore over swelling of the area. Not
difficult - one learns by experience.  The machine is called a fuser.  Take
a look at Zychem's website for more info

Subject: [accessibleimage] Questions about Swell paper and tactile graphics

Hi!

I have been reading the emails about using a printer with Swell paper to
create Tactile images. 
Please forgive my questions if they are ignorant. I haven't heard of this
before and it sounds very interesting. 

Am I understanding correctly? You have an image, say a picture of a cat, you
send the picture to an ink-ject printer loaded with this special paper,
Swell paper, and it prints a raised line drawing?

If this is not correct could you please explain it to me?
Thanks
