油墨主要有：以氯化合成樹脂和聚酰胺等作為連結料樹脂的聚酰按類油墨；以丙烯酸類共聚體作為連結料樹脂的丙烯酸類油墨；以聚異氰酸酯等作為連結料樹脂的聚異氰酸酯類油墨；

墨槽繼續使用，加上塑料薄膜對油墨沒有吸收性，所以回版印刷油墨必須容易揮發乾燥，且貼度要低，流動性好，流回墨槽的油墨復溶性好。


型料薄膜凹版油墨所使用的料要求色彩鮮艷、者色力強、分散性好。如在油墨中用了適量的顏料後已達到了粘度和厚度的要求，就可不用填充料，


填充料一般用輕質碳酸鈣、沉塑料薄膜凹版印刷的表印油墨和里印油墨所使用的連結料不同。表印油墨主要有：以聚澱硫酸鋇等。


酰膠和硝酸纖維素做連結料樹脂的聚酰胺類油圈：以丙烯酸和丙烯酸酯的共聚體作為連結料樹脂的丙烯酸類油墨；


以氯乙烯和乙酸乙烯的共聚體作為連結料樹脂的氯乙烯類油墨，但用得最多的還是聚酰膠類，


而里印油墨主要有：


以氯化合成樹脂和聚酰胺等作為連結料樹脂的聚酰按類油墨；


以丙烯酸類共聚體作為連結料樹脂的丙烯酸類油墨；


以聚異氰酸酯等作為連結料樹脂的聚異氰酸酯類油墨；


常用的輔助劑主要有沖淡劑、消泡劑、去黏劑、增黏劑、乾燥劑等。。。。
