Description
耐候性の観点から、インクジェットインクに顔料インクを採用するインクジェット印刷機が増加する傾向である。顔料インクの問題点としては、印刷部分の印刷ムラが挙げられる。印刷ムラとは、印刷速度が速い時に印刷用塗工紙のインク吸収性にバラツキが発生し、インクが乾燥した後の最終的な印刷画像において定着したインクの濃度が不均一となる現象である。インクジェット印刷に用いるインクは色材の濃度が低く、オフセット印刷に比べて印刷ムラが顕著となり易い。印刷ムラによって印刷物の商品価値は低下し、故に、印刷ムラを抑制することが求められる。 From the viewpoint of weather resistance, there is an increasing tendency for inkjet printers that employ pigment inks as inkjet inks. As a problem of the pigment ink, there is a printing unevenness in a printing portion. Printing unevenness is a phenomenon in which the ink absorbability of the printing coated paper varies when the printing speed is high, and the density of the fixed ink in the final printed image after the ink is dried becomes uneven. . Ink used for ink-jet printing has a low density of the color material, and printing unevenness is likely to be noticeable compared to offset printing. The commercial value of the printed matter is reduced by the printing unevenness, and therefore it is required to suppress the printing unevenness.
また本発明において、1m2の印刷用塗工紙に含まれる炭酸カルシウムのカルシウム量Aと炭酸カルシウム以外のカルシウム化合物のカルシウム量Bのカルシウムイオン換算mmol比(A/B)が1以上50以下の範囲であることが好ましい。より好ましくは1以上30以下である。この範囲にすることによって、インク定着性、印刷部分の印刷ムラの抑制あるいはインク吸収性の向上効果をより得ることができる。
In the present invention, the calcium ion-equivalent mmol ratio (A / B) of the calcium amount A of calcium carbonate and the calcium amount B of the calcium compound other than calcium carbonate contained in 1 m 2 of the coated paper for printing is 1 to 50. A range is preferable. More preferably, it is 1 or more and 30 or less. By making it within this range, it is possible to obtain more effects of improving the ink fixing property, the printing unevenness of the printed portion, or the ink absorbability.
