Abstract: A polishing pad includes a polishing layer having a first major surface and a second major surface opposite the first major surface. The polishing pad further includes a subpad, which is coupled to the polishing layer, and has a first major surface and a second major surface opposite the first major surface. At least 50% of the subpad, based on the total surface area of the first major surface of the subpad, is optically transparent.

Abstract: A printing system is provided. The printing system (300) includes a printing roll (310) having a rigid printing pattern (312) on a surface thereof configured to receive an ink material (330); and an inking roll (320) positioned adjacent to the printing roll. The inking roll includes an elastically deformable surface and a number of cells (324) disposed on the elastically deformable surface. A method of printing is also provided. The method includes (a) inking at least a portion of a rigid printing pattern (312) on a surface of a printing roll (310) by contacting the rigid printing pattern with an inking roll (320); and (b) contacting the rigid printing pattern with a substrate (350), transferring the ink material from the rigid printing pattern to a surface of the substrate. Printing systems and methods can achieve higher printing feature resolutions than typically achievable via flexographic printing.

Abstract: A printing system (200) including a printing roll (220) is provided. The printing roll (220) includes an elastically deformable and compressible inner layer (224) and a thin outer shell (222) to cover the inner layer (224). The thin outer shell (222) includes a pattern of raised print features (223) to receive ink material thereon. The inner layer (224) is softer and thicker than the thin outer shell (222), and optionally, the thin outer shell (222) is removable from the inner layer (224). The inner layer (224) of the printing roll (220) has a thickness, a compression force deflection value and an elastically-deformable compressibility such that the raised print features (223) of the printing roll (220) do not slide or deform with respect to the printed web (2) in an amount to generate a substantially visible dot gain.

Abstract: Methods and apparatuses for applying coatings (9) on a moving web (3) are provided. A slot die (20) and a back-up roll (11) engage with each other. The back-up roll has a deformable inner layer (12) with a surface thereof covered by a deformable outer layer (14). The slot die and the flexible web at a contacting area are impressed into the back-up roll with an engagement depth D, which enables formation of a coating having a substantially uniform thickness.

Abstract: A powder-rubbing apparatus comprises: a rotatable rubbing roll having a rotational axis; a substrate path; an oscillating mechanism for oscillating the rotatable rubbing roll along the rotational axis; and a powder coating die comprising an inlet port in fluid communication with an outlet port disposed adjacent to the substrate path. The substrate frictionally contacts the rotatable rubbing roll within a rubbing zone. A dispenser for dispensing gas-borne powder is in fluid communication with the inlet port of the powder coating die. The dispenser is aligned such that at least a portion of a gas-borne powder dispensed from the powder coating die is deposited directly onto at least one of the rotatable rubbing roll or the substrate and conveyed into the rubbing zone. A method of using the powder-rubbing apparatus and a powder-rubbed web preparable thereby are also disclosed.
