ABSTRACT:
In a process for choosing a color most closely replicating an object's actual color, a computer processor programmed with a database of sets of digital color data and the corresponding formulas for producing those colors using one or more thermal transfer foils, or vinyl sheet materials, is provided. The process includes sensing an object's color and producing a set of digital color data representing the sensed color. The set of digital data representing the sensed color is then supplied to the computer processor which is operated to compare the supplied set of digital color data to the digital color data stored in the database. The computer processor then outputs, to a display, a listing of the closest color matches found in the database, to the sensed color. The user then selects the color and formula defined by the digital information stored in the database corresponding to a color producible using thermal transfer foils or vinyl sheet materials, to that most closely matching the sensed color.
