Abstract: Systems and processes for making a flexo plate, and plates made thereby. Non-printing indicia defined by areas of presence and absence of polymer in the plate floor created using microdots imaged during a LAMS layer imaging step are readable downstream of the washing or other non-cured-polymer-removal step but not to print in the printing step.

Abstract: A copper-based ink contains copper hydroxide and diethanolamine. The ink may be coated on a substrate and decomposed on the substrate to form a conductive copper coating on the substrate. The ink is low cost and micron-thick traces of the ink may be screen printed and thermally sintered in the presence of up to about 500 ppm of oxygen or photo-sintered in air to produce highly conductive copper features. Sintered copper traces produced from the ink have improved air stability compared to traces produced from other copper inks. Sintered copper traces having sheet resistivity of about 20 m?/?/mil or less may be obtained for 5-20 mil wide screen-printed lines with excellent resolution.

Abstract: According to aspects of the embodiments, there is provided a method of measuring the amount of fountain solution employed in a digital offset lithography printing system. Fountain solution thickness is measured using a diffractive optical element (DOE) configured with grating surfaces varying in a periodic fashion to hold an amount of fountain solution. When radiated with a light source the combination of the grating surface and the fountain solution therein reduces the scattering of the surface structure (“contrast”) that gives rise to a diffraction pattern. The diffractive optical element can be placed on the printing blanket of the lithography printing system or on a separate substrate.
