A. There are two kinds of blind words in the new edition: There are two possibilities for this dirty version:
a. New words with small size and many strokes have residual oleophilic emulsion film between the strokes, causing the new version to have ink blinking. This is usually corrected by retouching the pen or reprinting. solve.
b. There is no problem with the new version of the blank space. When the new version is inked, there is no dampening fluid between the strokes to protect it, causing the new version of the ink to be printed. This should be treated in time with a wetting fluid, gum arabic or PS plate cleaning paste.
c, the new version of printing [encyclopedia] microblogging only some time after the blink of an eye, is generally the number of water over the place or the ink is too thin resulting in more than the place where the stroke becomes a blind eye. This will promptly adjust the amount of water supply and the fluidity of the printing ink, and use the PS plate cleaning paste to handle this place.
