Multi Color Recording Medium

Metalized paper can provide for multi-color recording by forming the covered contrast layer of narrow bands of different colors and clearing matrices of small areas of the desired colors to form the characters.

In the figure, the paper base 1 is coated with a repeating pattern of narrow parallel stripes 2 of desired colors, such as primary colors. One or more sensible locating stripes 3 of a magnetic ink or phosphorescent ink are also placed on the paper, and the entire surface metalized with aluminum 4 to cover the stripes.

During recording in a direction transverse to the stripes, a sensing head detects the locating stripe 3 and signals the beginning of the color field. Thereafter, the print head is controlled to selectively remove a matrix of small areas 5 of the metal coating and expose bits of the desired underlying colors.

Recording sheets can alternatively be coated with large solid fields of underlying colors to permit the page to carry highlighted recorded matter. These fields likewise require suitable locating marks.
