A Snap N Place sign system and method for supporting a sign message includes a sign substrate associated with a number of rubber nipple fasteners and a lens. The sign message and the lens further include mounting holes placed at their corners for securely holding the sign message in association with the sign substrate and lens. The rubber nipple fastener can be pulled through the mounting holes in the lens utilizing a relatively low insertion force. The rubber nipple fasteners can be driven axially into the mounting holes in the lens with a flexible tab engaging the lens and flexing as they move through the hole in the lens. The rubber nipple fastener can be specifically designed such that the force required to install or push the rubber nipple fastener through the mounting hole is relatively low thereby facilitating ergonomic considerations. The Snap N Place sign system is capable of holding signs of a variety of thicknesses and sizes.

A plastic orifice plate for an ink jet printhead and manufacturing process therefor which includes electroforming a metal die having raised sections thereon of predefined center-to-center spacings, and using the die to punch out openings in a plastic substrate of a chosen thickness to form a plurality of closely spaced orifice openings in the substrate. The orifice plate can be of a chosen transparent material and secured to a printhead substrate where the dynamics of ink flow can be viewed through the orifice plate during printhead testing and evaluation.

Plastic orifice plate for an ink jet printhead and method of manufacture

The present invention is directed to a compound bore nozzle plate for a thermal ink jet printhead and is manufactured by electroforming nickel onto a nickel substrate which has been masked by a plurality of mask segments of predefined geometry. This geometry consists of a plurality of base segments upon which have been formed a corresponding plurality of post segments of greater vertical dimension and smaller lateral dimension than the base segments. This mask geometry enables greater center-to-center orifice spacing to be achieved without unacceptably reducing the thickness and structural integrity of the nozzle plate.
