In the process of iron box printing, there are many reasons for ink floating phenomenon, among which the main reasons are: (1) excessive ink or ink quality is too thin; (2) wet liquid stock is too light or too little water; (3) The wetting liquid is too thick; (4) the ink roller pressure is too light; ⑤ poor water resistance of ink; ⑥ Photosensitive glue escape when printing.
The corresponding solution is: (1) reduce the amount of ink, increase the thickness of the ink; ② Increase the amount of water or increase the acidity of the wetting fluid; (3) Dilute the wetting fluid; ④ Increase the pressure of the ink roller; ⑤ Increase the content of bonding material; Strengthen print quality inspection.
