  • Patent number: 6951173
    Abstract: Disclosed is a template transfer assembly and method that features a template transfer substrate, and a template having first and second sides, with the first side facing away from the template transfer substrate and the second side facing the template transfer substrate and having mold pattern formed thereon. Polymerized imprint material is disposed between the second side and the template transfer substrate to fixedly attach the template to the template transfer substrate. The method of transferring an imprint lithography template includes dispensing a selected volume of imprinting fluid onto the template transfer substrate, placing the template upon the selected volume; and converting the imprinting fluid to solid imprint material. The selected volume of imprint material is of sufficient quantity to fixedly attach the template to the template transfer substrate while maintaining a space between the mold and the template transfer substrate.

  • Patent number: 6938542
    Abstract: An embossing tool for embossing a sheet of material has a body formed with a fissure for receiving the sheet of material, a lever pivotably mounted about a pivot point on the body and a block positionable between the lever and the body. The block has an embossing face moveable along a first axis, and further has a center riser configured to receive the lever. At least one resilient member is provided, adjacent to the embossing face along a second axis, spaced apart from the first axis, and disposed between the block and the body. When the block is positioned between the lever and the body and when the lever is pivoted about the pivot point between a first position and a second position, the lever engages the block having the axially moveable embossing face to emboss the sheet of material.

  • Patent number: 6931991
    Abstract: A method of operating a laser drilling system to manufacture gravure printing plates without etching or the use of hazardous chemicals includes activating a laser drilling system, including a picosecond laser, light valves, and a mechanism adapted to rotate a gravure cylinder blank. Operation of the light valves, includes setting the light valves to block and/or allow pulses of laser energy propagating from the laser drilling system that can ablate a linear pattern of cells along a substantially entire length of the gravure cylinder blank. Drilling of cells includes targeting the laser drilling system on the gravure cylinder blank, such that ablation of materials occurs as sub-beams propagate along an optical path to the target area and impinge upon the gravure cylinder blank, wherein specific cells within the target area of the gravure cylinder blank are drilled or not drilled according to settings of the light valves.

  • Patent number: 6915738
    Abstract: A stencil making device of the present invention includes a front tension roller pair located downstream of the nip of a thermal head and a platen roller for applying tension to a stencil. The front tension roller pair is made up of an upper roller formed of rubber and a lower roller formed of metal. The lower roller is formed with a plurality of groove portions spaced from each other in the axial direction and each having a small diameter not contacting the stencil. The groove portions therefore reduce the area of contact with the stencil for thereby reducing the influence of static electricity on the stencil.
