example 1

[0027]constructed roughly as figure 1 and figure 2 Printing equipment shown. The printing roll has a diameter of 12 cm. The roll has a predetermined pattern of connected diamonds in both the first zone and the second zone. On the stainless steel doctor blade, the three stops consisted of a vinylpolysiloxane impression material commercially available as 3M ESPE7302 EXPRESS from 3M Company, St. Paul, MN against rollers form.

[0028] The water-soluble ink disclosed in U.S. Patent 4,895,631 is dispensed onto the doctor blade in the first zone and is available as 9301 Opaque White UV Flexographic Ink from NazdarInk Technologies, Shawnee, Kansas. Shawnee, KS) commercially available UV-curable non-water-soluble ink was dispensed onto the doctor blade in the second zone. After a pause to allow the roller to be inked, printing begins on a substrate of conventional polyester terephthalate (PET) film, conveyed at a line speed of 2 m / min and at a pressure of 1 lb / line inch (1.75 N...

example 2

[0030] The film according to Example 1 was deposited by sputtering equipment of conventional type, eg, a roll-to-roll vacuum chamber, similar to the systems described in US Patents 5,440,446 (Shaw et al.) and 7,018,713 (Padiyath et al.). A 40 nm thick layer of indium tin oxide (ITO) was deposited on the substrate in a first zone. The film is then rinsed with water so that the water soluble ink dissolves away in the first zone with a portion of the sputtered layer over the predetermined pattern. After rinsing with water, the fiducial marks printed with the UV curable ink in the second zone remained on the film. Predetermined patterns formed in this manner may have features with dimensions less than 20 mils (0.5 mm).

example 3

[0032] constructed roughly as image 3 device shown. A first ink, commercially available from Nazdar Ink Technologies as 9301 Opaque White UV Flexographic Ink, was dispensed from a first ink stick onto a microflexographic printing roll in the first zone. The microflexographic printing roll has a predetermined pattern of spaced apart rectangles in the first zone. A second ink, commercially available from Nazdar Ink Technologies as 9319 Base Process Blue Ultraviolet Flexographic Ink, was dispensed in the second zone from the second ink stick onto the microflexographic roll. The microflexographic roll has a predetermined pattern of spaced apart rectangles in the second zone. These inks were printed from an anilox roll onto a substrate of white paper coated with a silicone release liner and then coated with a thin layer of pressure sensitive adhesive, specifically with 90% by weight Random copolymer of isooctyl acrylate and 10% by weight acrylic acid. After printing, the web p...

Abstract

The present invention provides a method of achieving precise registration in a roll-to-roll process by simultaneously depositing multiple inks onto a printing roll. One of these inks prints a pattern of fiducial marks onto a substrate, while the other ink prints a predetermined pattern on the same substrate, such that the predetermined pattern imparts a predictable spatial relationship to the pattern of fiducial marks. Therefore, even if the ink forming the predetermined pattern is not visible, or its contrast to the substrate is so low that it is barely visible, or even has been dissolved in a subsequent process, the predetermined pattern can still be known by referring to the pattern of the fiducial marks Where.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of US Provisional Application 61 / 739,992, filed December 20, 2012, the disclosure of which is incorporated herein by reference in its entirety. Background technique [0003] The manufacture of articles such as flexible electronic or optical components may involve the application of layers of material deposited or formed on elongated substrates or webs. In particular, a pattern of material may be deposited in layers on an elongate substrate such as a web in a plurality of deposition steps. Some articles require precise registration of features applied on one or both sides of the substrate. [0004] To achieve accurate registration between layers, both transverse (crossweb) and longitudinal (downweb) orientation must be maintained as the substrate moves through multiple manufacturing steps. Maintaining registration between layers formed on the substrate becomes more complicated when t...
