| Title: |
Medium for a Color Changer |
| Abstract: |
A flexible medium for a scrolling color changer and method of making
thereof. The medium is made by applying an ink using a Meyer Rod which
has varying cell lengths along its length. This leaves varying size cells
of ink at different locations along the length of the medium. The ink has
special characteristics whereby its evaporation rate and viscosity are
carefully controlled. The viscosity is such that an amount of levelling
will occur will be equal to the distance between any cells, but that cell
to cell levelling will not, in general, occur.
