This invention relates generally to a perfectly registered substrate product and its novel method of manufacture. Specifically, this invention relates to a novel cutting method used to create advertising, media, and other products made out of different substrate materials that have registered color and graphics, and the resulting products. More specifically, this invention relates to a novel method for processing a continuous web or individual sheets of substrate using “kiss cutting” to generate multiple page advertising brochures, magazine inserts, direct mail pieces, fliers, games, and the like, and the products generated by the method.
Advertising brochures and fliers are well-established media for advertising goods and services. An essential attribute of such media is that it must attract and hold a viewing person's attention. These printed publications must therefore be visually attractive and aesthetically appealing.
One particular type of advertising brochure, sometimes called a gatefold, has one or more pages that can be opened by the viewer, in the manner of book pages, to reveal printed matter inside, previously covered by the pages and therefore unseen. The unopened pages may also have printed matter on their top-side, and a cut, allowing the pages to be opened. To ensure visual attractiveness this top-side printed matter must be properly “registered” on both sides of the cut. Any misalignment or change of color from one side of the cut to the other will detract from the aesthetic appeal of the brochure, thereby diminishing its advertising effectiveness.
A solution to this registration problem is to first complete the printing or other patterning of a substrate material, such as paper, MYLAR®, plastic, plastic film, foil or fabric, and then form the openable pages through a combination of folding the substrate, attaching one segment of the substrate to another segment, and cutting some layers of the substrate, with the cut or cuts slicing through the patterning. If the various pieces of the substrate formed by the cuts cannot move relative to each other after the cuts are made, then the desired registration across the cuts is guaranteed by construction.
Different pieces of the substrate remain fixed relative to each other if the cuts are carefully made only in some layers of the substrate and not in others. One method for accomplishing this is known as “kiss cutting.” In this method, the substrate is configured as a stack of sheets on top of each other, and only the sheet or sheets nearest one side of the stack are cut, leaving other sheets above or below them uncut. This type of cutting can be accomplished, for example, mechanically or optically. Mechanical kiss cutting is done by a die, slitting wheel, knife, or other device or devices with one or more sharp edges. Optical kiss cutting is performed using a laser or other optical device.
Current systems use kiss-cutting in processes for cutting smaller paper or substrate pieces out of larger sections of paper or substrate. For example, European patent EP 0 525 530 B1 to Bootman discloses a method of making perfume-containing pouches for inclusion in magazine advertisements. The individual pouches are separated from a web by kiss-cutting. The pouches can be decorated with artwork designed to match already existing artwork on the magazine page. The kiss-cutting, however, plays no role in this matching other than to define the individual pouches. U.S. Pat. No. 5,953,885 to Berman et al discloses a method of making multiple cosmetic samplers from a web of substrate material. The method involves folding the web and kiss-cutting to define the individual samplers. U.S. Patent Application Publication US 2002/0096241 A1 to Instance discloses a method of producing self-adhesive labels. The labels are separated on a web by cutting only through a top substrate layer, leaving a bottom backing layer uncut.
An object of the present invention is the novel application of kiss-cutting to the mass production of patterned substrates for the purpose of maintaining registration of the pattern across the cut or cuts, as described above. A further object of the present invention is to simplify the separation of the web into the individual products.
Previously known methods of producing such properly registered substrates tend to be more cumbersome, time-consuming, and wasteful of material; hence potentially more expensive. For example, U.S. Pat. Nos. 5,769,773 and 5,938,243 to DeSanto disclose a method for manufacturing advertising brochures from a continuous paper web and the resulting paper products. DeSanto's method provides for cutting the web longitudinally at designated intervals, then folding the web over to create brochures with a continuous back page and a front page with a slit in it, such that consumers may open the brochure to access the advertising material inside. The folding step occurs after the slitting step, which may increase the risk of misaligning the top pages of the resulting product brochures and affect the printing registration.
In addition, this and other existing methods for creating advertising and other media paper products make only intermittent cuts to create the gatefold products, thereby leaving “margins” on the individual products that must be cut off. This adds additional steps and machinery to the methods, increasing manufacturing time and expense. In the DeSanto patents, for example, while the web is still substantially intact, the individual paper products are, by mechanical necessity, joined by uncut strips at the top and bottom, extending across the entire width of the web. In order to complete and properly separate the individual products along the web, these strips must be completely removed; otherwise the pages cannot be opened. This requires at least two carefully positioned transverse cuts by at least two independent knives, and creates wasted substrate material.
By contrast, the kiss cuts of the present invention are made after the folding step, and are therefore more likely to preserve the alignment of the pattern across these cuts. Furthermore, these kiss cuts are continuous along substantially the entire length of the web or individual sheets of substrate, but not through the entire thickness of the substrate. The substrate therefore remains intact without the need for top and bottom margins. The individual products can then be separated with one transverse cut at the top and at the bottom using a single knife or other cutting device—according to this embodiment of the present invention, the process is simplified and the amount of wasted substrate material is reduced. Alternatively, two or more knives can be used if additional material must be removed between each product, or at the top and/or bottom of each product, in order to meet customer demands.
The present invention provides a novel method of manufacturing advertising brochures, magazine inserts, and other related paper products from a continuous web, or one or more individual sheets of substrate, using kiss-cutting to create multiple advertising or printed surfaces. The method eliminates the problem of imperfect registration, thereby providing a product with the highest standard of printing quality for advertising, marketing, direct mail, and other printed materials.
According to one aspect of the present invention, a continuous web or one or more individual sheets of substrate is printed, on one or both sides. The substrate is any material capable of receiving and retaining print, and the print can be either in color or black and white or a combination thereof. Substrates according to the present invention include paper, MYLAR®, plastic, plastic film, fabric, and metal foils. The substrate is also optionally coated with one or more coatings, including but not limited to fragrances, including fragrance oils, varnish, latex, including latex “scratch-off” materials, sublimation and other inks, and cosmetics, such as eye shadow, blush, lip gloss, lipstick, etc. It will be obvious to one of skill in the art that many types of substrates can be printed upon and are therefore contemplated by the present invention and many different coatings can be applied to various substrates, such that the present invention is therefore not limited to the previous lists.
The substrate, whether in continuous web or individual sheet form, is mechanically displaced in one or more places to create two or multiple layers, the layers sitting on top of one bottom layer. Mechanical displacement can be folding, ribboning, or any other method of displacing a segment of the substrate to create two or more layers. One or several of the top layer(s) of the substrate is then longitudinally “kiss cut” in the same direction that the substrate is traveling as it is being processed. As many layers as are required are cut through, leaving at least the bottom layer uncut. The process can be adjusted so that the required number of layers are “kiss cut” according to customer specifications for the final desired substrate product. Mechanical displacement can occur before or after any desired coatings are applied to the substrate.
Importantly, the “kiss cut” method slits at least one layer of substrate after the substrate has been printed upon and after the paper has been displaced into the required format for the final product. According to an alternative embodiment, additional mechanical displacement of one or more segments of the substrate may occur after the substrate has been kiss cut. The “kiss cut” advantageously provides perfect or near-perfect registration of printing color and graphics.
According to an aspect of the present invention, “kiss cutting” occurs by mechanical or optical cutting. Mechanical cutting can occur by a die, slitting wheel, knife, or other mechanical cutting method known to those of skill in the art. Optical cutting can occur by laser or other optical cutting method known to those of skill in the art.
The longitudinal “kiss cut” extends substantially continuously throughout the entire length of the substrate. After the substrate is “kiss cut”, when the substrate is in the form of a continuous web, it can be optionally further processed by transversely cutting the web into individual products at designated intervals. Importantly, each resulting product is free from any “extra” segment or margin due to the fact that the longitudinal “kiss cut” extends substantially the entire length of the web. Thus, the individual products have freely openable segments that provide additional advertising space, and that are created immediately upon transversely cutting the web into individual products without the need to further remove any “extra” segments or margins. Only one transverse cutting device is required to separate the individual products from each other but more than one transverse cutting device can be used.
According to an alternative embodiment, segments of substrate are removed from one or both ends of each individual product, in order to meet customer specifications, for example, to maintain uncommon bleed color at opposite ends of each product, or to create a particular sized product. In those instances, more than one transverse cutting knife or other device can be used to remove the necessary segment or segments from the individual products.
The product of the present method is generated by the novel “kiss cut” method of the present invention. Frequently, the resulting kiss cut product is an advertising brochure, magazine insert, or other media/informational paper product. Customers requiring improved registration of printing and graphics on their products will select the product and method of the present invention over others that do not provide sufficient registration.
