ABSTRACT:
A method for fusing thermal transfer prints to avoid blister-type defects. The method includes in order, the steps of rapidly heating respective print image portions to a first temperature slightly below their respective components boiling temperature, maintaining respective print image portions at approximately the first temperature for a time period sufficient to allow significant evaporation from said print portions and, after such period, rapidly heating such significantly dried print portions to the desired fusing temperature, above the components boiling points.
