Abstract A new method for analyzing the drying characteristics of ink has been developed using Differential Scanning Calorimetry (DSC). DSC is able to determine the drying time of an ink in 30–45 min. In contrast, the ASTM method uses a Beck-Koller (BK) Dryer instrument to draw a stylus across an ink film to evaluate film drying, which can take hours or days depending on the film. This DSC method is comparative and does not reflect dry times under standard atmospheric conditions. A commercial offset ink was analyzed using DSC and BK Dryer methods. The two methods correlated highly (r = 0.976) with DSC offering comparable or smaller relative standard deviations and a significantly shorter analysis time. This method has the potential to analyze any oxygen-dependent coating.

使用差示扫描量热法评估油墨固化时间的新方法

摘要 使用差示扫描量热法 (DSC) 开发了一种分析油墨干燥特性的新方法。DSC 能够在 30-45 分钟内确定墨水的干燥时间。相比之下，ASTM 方法使用 Beck-Koller (BK) Dryer 仪器在墨膜上画笔来评估膜干燥，这可能需要数小时或数天，具体取决于膜。这种 DSC 方法是比较性的，不反映标准大气条件下的干燥时间。使用 DSC 和 BK Dryer 方法分析商业胶印油墨。这两种方法与 DSC 高度相关 (r = 0.976)，提供可比较或更小的相对标准偏差和显着更短的分析时间。这种方法有可能分析任何依赖于氧的涂层。
