Abstract: A method for forming a three-dimensional object using layer by layer formation of the object through application of stereolithography. More specifically, the formation of a three-dimensional object using a three-dimensional printer based on thermal stereolithography and phase change materials comprising a combination of crystalline and amorphous compounds, that are derived from low cost, stable and bio-renewable materials.

Abstract: Ein indirektes Druckverfahren zum Drucken einer Geltinte. Das Verfahren umfasst das Bereitstellen einer Geltintenzusammensetzung in einem Tintenstrahl-Druckapparat. Tropfen einer Geltinte werden in einem bildweisen Muster auf ein Zwischenübertragungselement ausgestoßen, wobei jeder Tintentropfen ein im Wesentlichen zirkuläres Bild auf dem Übertragungselement bildet. Die Tintentropfen werden geliert und getrocknet oder verfestigt, um ein im Wesentlichen trockenes Tintenmuster auf dem Zwischenübertragungselement zu bilden. Das im Wesentlichen trockene Tintenmuster wird von dem Zwischenübertragungselement auf ein Endsubstrat übertragen.

Abstract: An indirect printing process for printing a gel ink. The process comprises providing a gel ink composition in an inkjet printing apparatus. Droplets of gel ink are ejected in an imagewise pattern onto an intermediate transfer member wherein each ink droplet forms a substantially circular image on the transfer member. The ink droplets are gelled and dried or solidified to form a substantially dry ink pattern on the intermediate transfer member. The substantially dry ink pattern is transferred from the intermediate transfer member to a final substrate.

Abstract: A method for determining whether an item has been exposed to an environmental condition during a monitoring period. The method includes placing a sensor at least in proximity to the item at the beginning of the monitoring period so that the sensor will be exposed to a level of an environmental condition that can be correlated to an exposure level of the item to the environmental condition; reading the sensor; and determining from reading the sensor whether the item has been exposed to the environmental condition. The sensor includes a detecting material comprising a photochromic or photothermochromic material, the detecting material selected so that upon exposure to the environmental condition the detecting material exhibits a detectable color change.

Abstract: A pigmented phase change ink composition comprising an ink vehicle, a dispersant, and pigment particles wherein the dispersant is a chemical compound of formula: (see above formula) wherein R1 is an alkyl group, aryl group, alkylaryl group or arylalkyl group with at least 23 carbon atoms, R2 is an alkylene group, arylene group, alkyarylene group or arylalkylene group with at least 2 carbons and X is a quaternary ammonium salt. The ink can be resistant to substantial aggregation and settling of the pigment particles in the melt and even when exposed to freeze thaw cycles.
