In a method for reinforcing a flexible sheet such that the flexible sheet will retain desired topographical features, a flexible sheet is positioned on a surface of a magnetic chuck. The surface of the magnetic chuck has a topography, such as a perfectly flat topography, such that a magnetic force of the magnetic chuck causes a first surface of the flexible sheet to be formed into a reverse topography of the topography of the magnetic chuck. A frame having greater rigidity than the flexible sheet is secured relative to the flexible sheet as the first surface of the flexible sheet is formed into the reverse topography of the topography of the magnetic chuck by the magnetic force of the magnetic chuck. The flexible sheet together with the frame secured thereto are removed from the magnetic chuck. The first surface of the flexible sheet retains the reverse topography of the topography of the magnetic chuck when the flexible sheet is removed from the magnetic chuck together with the frame secured thereto.

Method for reinforcing a flexible sheet

Printer heads are precision mounted relative to a plate on a printer carriage by assembling a plurality of identical printer head assemblies, each of the printer head assemblies including a printer head precision mounted to a printer head carrier, each of the printer head carriers having at least three alignment points. Openings are provided in a plate in precise locations corresponding to desired locations and orientations of the printer head assemblies on the plate. The openings each have at least three alignment points corresponding to the three alignment points on each of the printer head carriers. The printer head assemblies are positioned in corresponding ones of the openings and a force is applied against the printer head assemblies, such as by springs mounted on the plate, to cause the at least three alignment points on the printer head carriers to contact respective ones of the at least three alignment points in the corresponding ones of the openings. A printer head carriage having printer heads precision mounted to a plate is also disclosed.
