Ink: Before you ink, turn off the water button on the machine and then ink it. When printing a four-color overprint, the color sequence is arranged according to the drying speed of the ink. Normally, it is blue—red—yellow—black (four-color machine is reversed), and the ink is evenly wiped when the ink is applied. Ink roller, the ink is easy and less easy, when necessary, you can use ink fountain ink, in order to ensure uniform ink, good ink on the machine, so that the ink evenly distributed on the roller.
Hang-up version - will play a good hole, develop a good PS version, hanging on the machine's roller, remember to do PS version should be hung up, do not be skewed, (design can be done on a non-forest piece of an auxiliary level Straight line, use the world adjustment to print this line to the edge of the business card, with reference to whether this version is horizontal.

During this period, the car can be washed, replaced with ink, and the position of the first color of the dry paper can be collected, and then placed on the stacking table to carry out the second Color printing, printing is still the use of heaven and earth, side gauges, to adjust the position, if you see the layout is skewed, you need to immediately adjust, behind a few colors must completely rely on the location of the first color printing to align. Right after the position can be printed. The last two colors are also in accordance with this procedure!
