Abstract
A substrate for an inkjet printer is described herein. The substrate comprises a material selected to provide high contrast reflected light and having a print material receiving surface with a neutral response to the print material.
Claims22
A substrate for an inkjet printer, the substrate comprising a material selected to provide high contrast reflected light and having a print material receiving surface with a neutral response to the print material, a reflective backing layer, and a print material receiving surface support layer disposed between the print material receiving surface and the backing layer.
A drop placement test system for analyzing drops of a print material, the drop placement test system comprising:
- a test substrate system comprising a stage for a test substrate, the test substrate being a flexible substrate comprising a material selected to provide high contrast reflected light, the substrate having a print material receiving surface with a neutral response to the print material, the print material receiving surface comprising a transparent film, backing layer, and a print material receiving surface support layer disposed between the print material receiving surface and the backing layer;
- and
- an imaging apparatus with a light source disposed to illuminate the print material receiving surface using light matched to optical properties of the backing layer and a detector for capturing an image of light reflected from the test substrate.
A method, comprising:
- dispensing a plurality of drops of a print material from nozzles of a printhead of an inkjet printer onto a test substrate, the test substrate comprising a material selected to provide high contrast reflected light and having a print material receiving surface with a neutral response to the print material upon contact;
- imaging the drops using light matched to the material of the test substrate to be reflected by the test substrate with high contrast from light reflected by the drops;
- and
- collecting the test substrate using a roll.
