Abstract
Abstract A printing means for depositing ink or dye onto a web of cloth, paper, or plastic material. The web is moved under an ink reservoir and a quantity of ink is deposited on the web. A scraper limit blade removes most of the ink but permits small quantities of ink to remain on the web forming design patterns. Double limit blades and means for mixing colored inks on the web create a large variety of designs.

Total Claims: 13
Claim 1
Independent Claim
182 words
A machine for plateless printing of designs on a web comprising: a base plate for supporting the web as it is moved along in a direction parallel to its length; an ink dispensing unit mounted above the base plate and including an ink reservoir and a nozzle for delivering a flow of ink to a selected portion of the web; a notched limit blade with its lower edge resting on the web for distributing ink over the web surface and for creating tones or line patterns by the ink which passes under and through the blade notches, said limit blade mounted at right angles to the plane of the web but convexly curved so as to direct the ink along the blade toward the web edges, and wherein the limit blade is bent to form ink collection points, and wherein a vacuum system is also positioned above the base plate and includes a nozzle extending to the web at a collection point, an ink storage container connected to the nozzle, and a conduit connected between the storage container and a vacuum pump.
