Part of the ink leaked from the printing plate is called ink leakage failure. The reason for this is: some of the squeegee has been damaged; the pressure of the squeegee is large; the gap between the plate and the substrate is too large; the plate frame is deformed, and the printing pressure is insufficient. : Inhomogeneous ink; fine mesh; too fast printing speed. If the printing material and the ink are mixed with dust and printed without processing, the printing plate will be damaged due to the pressure of the squeegee; when the plate is underexposed, pinholes, etc., will cause the printing ink to leak. At this time, adhesive tapes, etc. can be used for emergency handling from the back of the plate. If this operation is not very fast, the ink on the layout will be dried, and the whole of the plate will have to be wiped with solvent. Wipe plates are also responsible for the delamination of the plates and are therefore well avoided. The ink leakage of the printing plate often occurs in the part where the ink stays, so this part is well reinforced at the time of plate making. |
