​適用於製作液晶油墨的主要是膽畫型液品之由於液晶制取不便，價格昂貴，目前只應用於特殊需求的溫度變化發色變化的裝飾等。

液品油墨是將封團在微膠囊中的液品及助劑等分散在連結料中配製而成的，液品油墨不以料構成彩色圖文，液晶墨層中的液晶感溫後會引起分子排列方向的改變，

從面有擇地吸收一部分波長的光而反射特定波長的可見光，從而呈現出色彩變化，液晶受自然光和人工白光以及某波長的色光照射時，由於折射現象而加強反射，

隨著溫度的上升，由長波長的顏色變為短波長的顏色（即按紅色一綠色一青色而變化）曲於液晶的分子排列並不像品體結構那樣牢固，

所以很容易受到電場、磁場、溫度、應力以及雜質等外部刺激的影響使其各種光學性質發生變化，液晶一般分為向列型、近晶型留型和異型四類，

適用於製作液晶油墨的主要是膽畫型液品之由於液晶制取不便，價格昂貴，目前只應用於特殊需求的溫度變化發色變化的裝飾等。

膽甾型液晶不能像普通油墨那樣，直接加人到連結料中即可使用為了不讓膽型液晶。
