[GreenKeys] TTY paper

[Til128 at aol.com]

It has been suggested that I send this tirade to the list explaining the  
paper that Eugene got and is sending around the country:

I did some  measurements on the new and old paper and came up with the 
following--

Original yellow Govt. TT paper. Dia. 4.5". Thickness: .004 inch Equals  20 
Lb. bond. (Typewriter/copy paper
)
Single Ply White Groundwood : Dia. 4.25. Thickness: .0045 inch Equals  24 
Lb bond.

NCR paper Dia .3.75. Thickness: .003 inch 15 Lb. bond.

Soooooooooooooo....even though the diameter of the groundwood/yellow  rolls 
are larger, the NCR paper would seem to have more or the same amount  paper.

To answer some questions--

Caliper:

Caliper refers to the thickness of a sheet of paper  expressed
in thousandths of an inch. This measurement is taken with a micro  meter.

Generally, the relation between caliper and basis weight  ....
the greater the caliper (the thicker the paper), the greater the paper  
weight.
