    • A marking agent concentration method includes concentrating the marking agent by removing at least some liquid carrier between particles without substantially removing retained liquid carrier within the particles and without substantially modifying the particle structure, which is supported by the retained liquid carrier. The concentrated marking agent is supplied to distributors or end users of liquid marking agent. A concentrated marking agent includes solid clumps of agglomerated particles and a liquid carrier retained within the particles' individual structure. The clumps exhibit a median size greater than 90 μm. The concentrated marking agent exhibiting a solids content of from 40 wt% to less than 90 wt%. A hard imaging method includes combining (42) a concentrated marking agent with additional liquid carrier, applying (44) a shear force, dispersing (46) particles from clumps, forming a liquid marking agent, and forming (48) a hard image using the liquid marking agent.
    • 标记剂浓缩方法包括通过除去颗粒之间的至少一些液体载体来集中标记剂,而基本上不除去颗粒内的残留液体载体,并且基本上不改变被保留的液体载体支撑的颗粒结构。 浓缩标记剂供应给液体打标剂的分销商或最终用户。 浓缩的标记剂包括附聚颗粒的固体团块和保持在颗粒单个结构内的液体载体。 团块的中位数大于90μm。 浓缩标记试剂的固体含量为40重量%至小于90重量%。 硬成像方法包括将浓缩的标记剂与另外的液体载体组合(42),施加(44)剪切力,从块分散(46)颗粒,形成液体标记剂,以及使用 液体打标剂。
