A flexible medium (520) for a scrolling color changer and method of making thereof. The medium (520) is made by applying an ink (500, 502, 506) using a Meyer Rod which has varying cell lengths along its length. This leaves varying size cells of ink (500, 502, 506) at different locations along the length of the medium (520). The ink has special characteristics whereby its evaporation rate and viscosity are carefully controlled. The viscosity is such that an amount of levelling (508) will occur, will be equal to the distance between any cells, but that cell to cell levelling will not, in general, occur. |
