Abstract
A donor ribbon and method capable of detecting donor ribbon type and aligning color patches relative to a print head. A dye donor ribbon having a predetermined width includes a plurality of donor color patches thereon. Separating adjacent ones of the patches is a space in which is formed a first stripe extending the entire width of the ribbon. The first stripe defines borders between the adjacent color patches. A second stripe of a predetermined width together with the first stripe are disposed in the space before a beginning one of the color patches to define a beginning sequence of color patches. The second stripe is adjacent to and spaced-apart from the first mark by a predetermined distance and also extends the width of the ribbon parallel to the first stripe. A ratio of the width of the second stripe to the distance between the second stripe and its adjacent first stripe is unique to each donor type and is used to inform the printer of the specific donor type loaded into the printer. In addition, presence of the first stripe between adjacent donor patches defines the beginning borders of each donor patch, so that each donor patch is precisely alignable with the print head.
