The present invention provides method and apparatus for printing a pattern on articles employing a printing plate having a grooved pattern therein in which ink is applied to such plate and a scraper blade passes thereover to remove the excess ink from the plate surface while leaving such ink in the grooves. An apertured shield can be placed over the scraped plate, the aperture positioned to expose the grooved pattern. A transfer printing pad is then contacted with the so-shielded grooved plate and picks up the ink pattern. The so-inked transfer pad is then contacted with an article to print the inked pattern thereon. In some embodiments, the apertured shield is omitted. Desireably the printing pad is resiliently mounted on a plunger having means to index its position over the inked and scraped grooved plate and then such plunger is indexed on a holder of the article to be printed to permit precise ink pick-up and transfer printing of articles employing one or more ink transfer and indexing steps to print a precise pattern of letters and/or designs on one or more lines, in one or more colors. Further such printing apparatus can readily be operated by hand.
An apparatus for transfer pad printing comprising a printing plate having a surface with a grooved pattern therein, means to apply ink on said surface and in said grooved pattern, means to remove the ink from said surface while leaving it in said grooved pattern, a separate unconfined and freely movable portable pad holder having a transfer pad mounted thereon, which pad holder is a resiliently mounted plunger which is completely detached from said printing plate, manual means to contact said pad with the grooved surface to pick up the inked pattern thereon, means to remove the so-inked pad from the grooved surface and manual means to contact said pad with an article to print said pattern thereon, said printing plate being mounted in a plate holder having a first indexing means and said plunger having a second indexing means to engage said first indexing means and permit the accurate indexing of said plunger and pad with said plate holder and pattern.
The apparatus of 34, wherein said apertured frame is secured in place on said fabric by adhesive tape means.
