Abstract
A laminating method of forming a pre-press proof (200) which comprises the steps of forming a lamination sandwich (210); placing lamination sandwich (210) at the entrance to a laminator (10) such that the lamination sandwich (210) passes through a nip portion (220) formed by a first lamination roller (120) and a second lamination roller (130) and, wherein at least one of the first lamination roller (120) or second lamination roller (130) comprises a substantially solid core (330), a first deformable layer (250) having a 60-80 durometer and surrounding the substantially solid core (330), and a second deformable layer (260) having a 20-60 durometer and surrounding the first deformable layer (250).
Claims29
A laminator assembly comprising:
- a first lamination roller located on a first side of a media passage;
- a second lamination roller located on a second side of said media passage and opposing said first roller, wherein a nip portion is defined between said first lamination roller and second lamination roller so as to apply pressure to media in said media passage which passes through said nip portion;
- wherein at least one of said first lamination roller and said second lamination roller is a lamination roller comprising a substantially solid core, a first deformable layer having a 60-80 durometer and surrounding said substantially solid core, and a second deformable layer having a 20-60 durometer and surrounding said first deformable layer;
- and
- wherein said first deformable layer is bonded to said core.
A laminator assembly comprising:
- a moveable platen located on a first side of a media passage;
- a roller located on a second side of said media passage opposing said moveable platen, wherein a nip portion is defined between said moveable platen and said roller so as to apply pressure to media in said media passage which passes through said nip portion;
- wherein said roller comprises a substantially solid core, a first deformable layer having a 60-80 durometer and surrounding said substantially solid core, and a second deformable layer having a 20-60 durometer and surrounding said first deformable layer;
- and
- wherein said first deformable layer is bonded to said core.
A roller comprising:
- a substantially solid core, a first deformable layer having a 60-80 durometer and surrounding said substantially solid core, and a second deformable layer having a 20-60 durometer and surrounding said first deformable layer;
- and
- wherein said first deformable layer is bonded to said core.
A laminating method comprising the steps of:
- forming a lamination sandwich;
- placing said lamination sandwich at an entrance to a laminator such that said lamination sandwich passes through a nip portion formed by a first roller and a second roller;
- wherein at least one of said first and second rollers comprises a substantially solid core, a first deformable layer having a 60-80 durometer and surrounding said substantially solid core, and a second deformable layer having a 20-60 durometer and surrounding said first deformable layer;
- and
- wherein said first deformable layer is bonded to said core.
A laminator assembly improvements therein comprising:
- a first lamination roller located on a first side of a media passage;
- a second lamination roller located on a second side of said media passage so as to oppose said first roller, wherein a nip portion is defined between said first lamination roller and said second lamination roller so as to apply pressure to media in said media passage which passes through said nip portion;
- wherein at least one of said first lamination roller and said second lamination roller is a lamination roller comprising a substantially solid core, a first deformable layer having a 60-80 durometer and surrounding said substantially solid core, and a second deformable layer having a 20-60 durometer and surrounding said first deformable layer;
- and
- wherein said first deformable layer is bonded to said core.
A laminator assembly comprising:
- a first lamination roller located on a first side of a media passage;
- a second lamination roller located on a second side of said media passage so as to oppose said first roller, wherein a nip portion is defined between said first lamination roller and second lamination roller so as to apply pressure to media in said media passage which passes through said nip portion;
- wherein said first lamination roller is comprised of a substantially solid core, a first deformable layer having a 60-80 durometer and surrounding said substantially solid core, and a second deformable layer having a 20-60 durometer and surrounding said first deformable layer;
- and
- wherein said first deformable layer is bonded to said core.
