Screen printing ink firmness problem
If not enough, it can only change solvent-based ink, the solvent ink tension is small, ink layer spread, drying speed, adhesion will be much better, but the volatile substances on the human body and the environment is harmful, and flammable and explosive, need
If it is PVC tablecloth, you can try to corona the first surface of the printing process, so that the surface tension higher (recommended to 55 - 60 dyne), and then see if there is improvement.
Screen printing rarely use water-based ink, because the water-based ink in the non-absorbent substrate adhesion fastness is usually much worse than the solvent-based ink, plus silk ink layer thick, adhesion is more problematic.
