Abstract
A drop placement analyzer for an inkjet printer is described herein. The drop placement analyzer comprises a film support that has an opaque, optically non-interfering vacuum surface for immobilizing a film against the optically non-interfering vacuum surface and photographing drops disposed on the film from the same side of the film on which the drops are disposed.
Claims19
An inkjet printer, comprising:
- a processing table;
- a printhead coupled to a printhead support disposed over the processing table;
- and
- a drop placement analyzer with a film support that has an opaque, optically non-interfering surface for photography of drops disposed on a film, supported by the film support.
A drop placement analyzer for an inkjet printer, the drop placement analyzer comprising a film support that has an opaque, optically non-interfering vacuum surface for immobilizing a film against the optically non-interfering vacuum surface and photographing drops disposed on the film.
A method of processing a substrate, comprising:
- providing a support body that has a flat, opaque, optically non-interfering surface;
- disposing a transparent test substrate securely against the optically non-interfering surface of the support body;
- dispensing test drops onto the test substrate;
- illuminating the test substrate using light adapted for use with the optically non-interfering surface of the support body to minimize noise and distortion of light reflected from the optically non-interfering surface of the support body;
- and
- photographing the test drops on the test substrate.
