2) the choice of ink or ink itself quality problems.
3) The phenomenon of blocking plate in printing affects the normal overink of ink.
4) The viscosity of the ink is too high, and the pattern is incomplete or the line is broken when printing.
5) the surface of the substrate is uneven.
6) printing blade pressure is insufficient or uneven, resulting in uneven ink.
Solutions:
1) the use of slow dry solvent deployment ink.
2) replace the appropriate ink.
3) The customer correct choice of slow drying solvent dilution ink, and pay attention to the fabric screen printing over ink performance.
4) dilute ink or add thixotropic agent to reduce viscosity.
5) the processing of substrate surface (such as printing coarse grain substrate can be used up oil or other materials before printing).
6) Increase the strength of the scraper while printing, and pay attention to the uniformity of the scraping force.
How to maintain the service life of fabric screen printing
1) When using fabric screen printing, you should keep the screen distance, which is known to all. At this time, the pressure of printing and scraping is not too heavy; In addition, the distance between the ink plate and the screen is not close to prevent friction, which will lead to thin photographic slurry.
2) Because the mesh is glued on the mesh frame (whether it is a wooden frame, or a metal frame), before the use of the screen should be the screen inside the frame at the Angle of the seal, the general seiking company will apply a layer of glue or with adhesive seal, prevent ink or other solvents into the resulting mesh relaxation or fall off.
3) Fabric screen printing no matter how much attention, for a long time, the tension will change.
4. Clean up the printing screen after use and use special solvent to clean it, especially where there are patterns, but do not exert too much force; Make sure the design is transparent. Place the cleaned screen in a dry, ventilated place and pay attention to dust.
