Print the thief how to solve? So know in an instant by a speak!

Printing composite bags suddenly found in the process of the thief, so operators began to increase printing pressure! If printing pressure gap is 4 mm, will be reduced to 3 mm clearance, or a thief; Continue to add printing pressure, adjust to 2 mm, the cardboard has been crushed, print and paste, but the printing is the thief & middot; · · Then print the captain finally to management personnel, collective research the causes of the thief. Ink issue? Board problem? Equipment problem? One time in the past, so it took a lot of time and energy, still can't solve. Is actually not hard to solve problem, we there are mistakes on operation method, problems always happened to adjust. So how to avoid printing thief and solve the problem of printing the thief? First, before printing to inevitable 1, before the computer to check ink printing ink viscosity, whether normal printing thief among the common problem is the ink viscosity is too low, after using several times easier to produce. Because in the process of production, often to the printer ink barrels of water, resulting in a decline in ink viscosity. Triggering printing the thief, so before the computer must to test the ink. 2, check whether the print print good use for a long time or too much ink printing surface dirt, can reduce the print ink transfer, after the ink transfer to reduce, printing the thief phenomenon will happen very often. 3, of cleaning anilox roll is directly affect printing conditions, is a big part of anilox roll jams are not clear, the anilox roll of ink quantity is small, resulting in printing the thief phenomenon. Second, learn to printing the thief elimination method 1, the first test is not the cardboard thickness value, then check the cardboard from the paper feed unit after the cardboard thickness value, whether the cardboard has been feeding wheel crushing. If the crushing first solve the problem of cardboard crushing, paper gap is the thickness of the cardboard - 0. 3mm。 2, check whether the print pressure is normal, can view the amount of ink printing surface whether there is enough. Print hardness field fit in 34 - 36 degrees. 3, the above is correct to add printing pressure value, pressure value should not be too big, too easy to produce printing paste, printing wear speed slow. Of course, if the printing ink viscosity is correct, print, anilox roll or a good printing thief phenomenon, main direction to ink technology as the leading factor, do not always printing pressure increase, can continue to improve the ink viscosity, and the permeability of ink. Can also adjust the printing machine as a state of every piece of paper for printing.
