Abstract
A method of preparing a plastic mask for paste printing with a plastic sheet being provided with an area containing a predetermined pattern including one or more through-holes is carried out by the steps of bringing the plastic mask provided with electroconductive material on at least one surface into close contact with a printing material while applying an electrical ground potential to the electroconductive material and then using the mask for paste printing by spreading and pressing a past to cause it to pass through any of the through-holes forming the predetermined pattern for deposit on the printing material and then removing the mask from the printing material to leave the paste printing pattern.
Claims12
A paste printing method comprising the steps of:
- preparing a paste printing mask to include a plastic sheet having an area containing a predetermined pattern including one or more through-holes extending from an upper surface of the plastic sheet to a lower surface of the plastic sheet and providing at least one of the upper surface or the lower surface with an electroconductive layer thereon;
- bringing the paste printing mask into close contact with a printing material while applying an electrical ground potential to the electroconductive layer on at least one of the upper surface or the lower surface;
- filling each of said through-holes in said area with a paste by spreading and pressing said paste on said paste printing mask;
- and
- removing said paste printing mask from said printing material leaving on said printing material a paste pattern in the same pattern as said predetermined pattern.
