Abstract
Methods, apparatus and systems are disclosed by which patterned layers can be formed in a roll-to-roll process using a variable and programmable means for applying liquids and solutions used in the patterning process.
Claims21
A continuous roll-to-roll method for forming a desired pattern on a flexible substrate of desirable length, the method comprising:
- a. providing a rotary-shaped template surface comprising a 3D relief in a roll-to-roll embossing process;
- b. providing a substrate upon whose surface a pattern complementary that of said relief surface is formed;
- c. providing a means for applying a fluid selectively in relationship to the 3D relief pattern of said template;
- d. contacting together said substrate and said rotary-shaped template with the intervening selectively applied fluid;
- and
- e. solidifying the relief pattern formed by said fluid,
- f. by use of a continuous roll-to-roll process, removing the substrate containing the selective relief pattern from the rotary template surface.
