改进的介质应用
摘要：
提供了一种方法和装置，包括提供具有圆柱形表面的可旋转辊，该圆柱形表面适于将供体元件缠绕在其上。供体元件被固定于辊上，并且在对介质施加张力的同时将供体元件的第一部分缠绕到圆柱形表面上。张力然后被减小，以改变供体元件的第一部分与圆柱形表面之间的接触区域。供体元件的另外的部分然后被缠绕到圆柱形表面上。供体元件然后从辊被转移到基底上。
摘要（英）：

A method and apparatus are provided which include providing a rotatable roller with a cylindrical surface adapted to wrap the donor element on the surface. A donor element is secured to the roller and a first portion of the donor element is wrapped onto the cylindrical surface while applying tension to the media. The tension is then decreased to alter a region of contact between the first portion of the donor element and the cylindrical surface. An additional portion of the donor element is then wrapped onto the cylindrical surface. The donor element is then transferred from the roller to a substrate.
