Evaluation of the compatibility between low pressure melamine (LPM) film printing substrates and inkjet inks

摘要: Surface coated wood-based panels play a major role in the forest products industry as materials for construction and furniture elements numerous interior exterior applications. Their most important feature besides appropriate mechanical performance chemical durability is an appealing visual appearance. In this contribution, recent research on compatibility between two UV-curable inks different melamine formaldehyde based surface films presented. The texture properties of printing substrates were investigated by roughness measurements. Substrate free energy was measured contact angle measurements using three testing liquids covering wide range polarities (glycerol, ethylene glycol diiodomethane). physical shape inkjet ink drops which placed LPM monitored recorded over time used indicator wetting behavior tested hence printability. By combining pendant drop tension determined. theoretical findings confirmed technological tests. To end, hands-on method to establish ink-substrate flow coating tests run suitable selected printing. results closely related substrates.
