Abstract:
A dye transfer printer in which a dye donor web is capable of developing a crease-causing wave-like or ripple distortion across the donor web when the donor web is subjected to a longitudinal tension as it is advanced from a print head, over a web guide, and onto a web take-up spool, is characterized in that:said web guide is positioned to extend across the donor web and is adapted to be bowed to effect a curvature across the donor web in proportion to the longitudinal web tension in order to urge the donor web to spread substantially widthwise to reduce the likelihood of the wave-like or ripple distortion developing across the donor web, and said web guide includes a longitudinal guide bar for supporting the donor web substantially widthwise and that is compliant to become bowed lengthwise by the longitudinal web tension to effect said curvature across the donor web.
