Abstract
Apparatus having an array of print heads for transmitting energy to a colorant donor element to cause colorant to transfer to produce color filter array patterns in an image-receiving layer of a color filter array includes a structure for locating the colorant donor element and the image-receiving layer a precise sublimation gap G from the image-receiving layer surface; and for maintaining this sublimation gap G to compensate for dimensional variations in the image-receiving layer.
Claims4
Apparatus having a print head for transmitting energy to a colorant donor element, the energy causing colorant from the colorant donor element to transfer to an image receiving layer to produce a color filter array, the image-receiving layer having an image-receiving surface comprising:
- a) means for locating the colorant donor element gap and the image-receiving layer a precise sublimation gap G from the image-receiving layer surface during transfering the colorant donor element to the image-receiving layer,
- b) means for maintaining the sublimation gap G to compensate for dimensional variations in the image-receiving layer;
- and
- c) wherein the sublimation gap maintaining means includes sensing means for producing an electrical signal which is proportional to the variations in the sublimation gap G and further including means for positioning the print head in accordance with the electrical signal to maintain the sublimation gap thereby compensating for the dimensional variations in the image-receiving layer.
