Ibuonline printed circuit board manufacturer, exclude the application of the ghost in the machine malfunctions

??Ghosting is to appear in the printed products on two or more of the same blot, and its location right near. Automotiveried ghosting troubleshooting is to find the factors blot dislocation printed circuit board manufacturer.
??1 plate loose. Due to loosening of the printing plate, the position of the printing plate in the printing process can not be maintained constant, thereby twice blot transferred to the printed products on the old and the new position is not the same, and thus appears on the printed sheet ghosting. Re-clamping the printing plate, the circumferential direction, steering both sides of the screw to be in a working state, so that the version of the clamp and the relative position of the printing plate cylinder of the printing plate can remain unchanged; the automotived edition gap adjusting EDITION clamp to ensure that the printing process the same plate with the version of the relative position of the clamp; combined pressure of the mounting plate, so that the plate can be closely surrounded on the plate cylinder.
??. Blanket loose. As the blanket loose twice a position in contact with the plate (or impression cylinder) process is not the same, leaving the old and the new imprinted on the blanket, bound to transfer to the sheet ghosting. Clamp automotived mounted rubber blanket position is incorrect, reinstall the automotived, to ensure that in close contact on the plug on the blanket with clips and screws should be tight the middle, after tight on both sides, which prevents the blanket intermediate swim plot; rubber cloth tensioning force is too small, rotating worm agency reported hand blanket tension; blanket under the more uneven pad, caused some local rubber Jacobsson, blanket tight in some places, replace the gasket.
??3 of the paper on the impression cylinder slides. After the completion of the first-color printing in the multicolor printing sheet into the second-color printing, since the imprinted on the sheet is not dried completely in contact with the second color rubber City, again the printing side of the first color is transferred to the second The color on the blanket. If the position of the paper has changed, while the other parts are also in good working condition, the follow-up on the sheet, the first color blot should be the first color with the second color on the blanket blot completely overlap, because no ghosting; otherwise will produce ghosting. Dental films of the pressure on the impression cylinder is too small, increase the pressure of the dental film; severe dental pad wear on the impression cylinder, replacing the dental pad; the impression cylinder instigate paper amount is too little to adjust the rules to increase the amount of bite paper; printing too much pressure, reduce the printing pressure; ink viscosity is too large, plus the varnish or withdrawal viscosity to reduce the viscosity of the ink; thick full version, and replaced with a soft liner.
??4 paper deformation. The paper surface is uneven, the the paper moisture will cause the old and new imprinted do not coincide. Joint pressure (Sheung Shui can use the machine, but not on the ink) take the paper, so the paper after a decision imprint, basically flat state. And because itself has absorbed a certain amount of water, the possibility of re-swelling of much smaller.
??5. Drum string action. The plate cylinder, blanket cylinder, and other transfer cylinder moving string will cause the old and new blot not coincident, thereby generating a ghost. Automotiveefully check these the drum axial eye position device, inappropriate realignment, the general string Momentum controlled within 0.03mm.
Forum layout is unreasonable. Field change and mesh blocks should be properly arranged, the general should make it the axial distributed as evenly as possible, so ink viscous forces along the axial evenly distributed, thereby reducing the possibility of paper sliding.
