 Well it depends on what you mean by smaller braille.  Tiger technology
places dots exactly 0.100 inches apart within a braille cell.  Other
embosser range from 0.092 to 0.100.  Spacing between braille cells is 0.250
inches horizontally and 0.400 inches vertically for virtually all braille
embossers including Tiger embossers.  I suspect that you are referring to
the sharpness of braille that was typical of Tiger embossers a few years
ago.  If the punch force was set high, the dots could be sharp.  Current
generation Tiger embossers have dots that are much less sensitive to precise
punch settings.  They are pretty much identical to all others braille dots
on top but have slightly smaller bases in order to get 20 dots per inch when
embossing graphics.  I do not believe that braille readers can feel the dot
base, at least not without trying hard, so current generation Tiger braille
should certainly not feel "small".
 
Hope this is helpful.

Yes, it is smaller but when I requested a sample graphic (to see if the
tiger embosser was something I want eventually), the Braille labels on the
graphic did seem smaller (to me) but no harder for me to read (I do have
small hands though).

It is my understanding that due the fineness of the embossing of the tiger
braille embossers, the braille text is a bit smaller and harder to read.
Can anyone tell me if this is true.  I have never used a tiger embosser so I
don't know the quality of braille.  Thanks.

Hello Bret, if you are getting a Tiger embosser, you'll get TSS with it.
TSS has a good braille translator application that lets you translate
everything in MS Word, including math, and in Excel, including Excel charts
and graphics.  And you can print graphics from any standard application.  
 
Duxbury also supports math braille from MS Word I believe, so it is no
longer necessary to use Scientific Notebook.

Hi All,
  I am a Braille Transcriber with a school district, and am visually
impaired.  One of our students is going to be taking an algebra/geometry
class next year. We will be required to create all of the charts, graphs,
and other graphics for the class.  I am using Duxbury as my translation
software and am using a program called Scientific NoteBook to create all of
the mathematical text.  I was told that there is a program that works with
Duxbury called TGD Pro which allows you to copy an image and then import it
into a duxbury file.  Does anyone have any good ideas or suggestions for me
on the best way to create a tactile graphic electronically?  I have limited
sight, so being able to draw or create things by hand may be out of the
question.  Our district will be getting one of the new Tiger braille
embossers so I think I can create tables and charts with excel and then
emboss them.  Thanks for any suggestions or advice.
Bret
