     BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     This invention relates to printed matter and more particularly to the improved moving step article and method of making. 
     2. Background of the Invention 
     The history of printing started with the duplication of images around 3000 BC. It evolved from the use of round cylinder seals to impress clay tablets in Mesopotamia. Block printing on cloth preceded printing on paper, which became common by the mid 1400&#39;s. The origin of moveable type is credited to the Chinese around 1040, with metal moveable type appearing around 1230. These systems were not widely used due to the extensive set of characters. In 1439 the development of moveable type printing technology firmly established modern moveable type printing. Lithographic printing appeared in the late 1700&#39;s. Color printing, offset printing, screen printing, and flexography were further developments in the printing art. In the 1960&#39;s and 1970&#39;s, photocopiers, thermal, dot matrix, inkjet, and laser printers were introduced. The quality and desired appearance of the printed product is controlled by many criteria. A several considerations include printing press to be used and substrate type. Substrate determinations must consider the weight, density, opacity, paper grain, coating, moisture content, porosity and ink absorbency. 
     Coincident with the evolution and development of printing technology graphic design developments and improvements also progressed. Binding and finishing developments enhanced the appearance of the final primed product. The processes of cutting, collating, folding, and mechanical, chemical and thermal fastening enable the graphic designer to produce a wide variety of printed products. Many styles and designs of multi-page graphic design pieces have appeared. The uniqueness of print media styles provides an attraction to the viewer. This is especially true of advertising media, where each significant difference from the media produced by the advertiser&#39;s competition, provides an advertising advantage. Examples of these improvements include a brochure or card wherein upon opening the card, an interior portion of a card moves relative to the base card. A three dimensional variation of the movement effect includes so called “pop ups” whereby upon opening a folded card or brochure, a three dimensional pylon rises from the surface of the card, These effects are achieved through proper cutting folding and mounting and binding of the moveable piece or pylon on the interior surfaces of the card or brochure. Although these effects are well known to those skilled in the art, there still exists the challenge to produce print media pieces having unique motions or effects in order to achieve a competitive advantages over other print pieces. 
     There have been many in the prior art who have attempted to solve these problems with varying degrees of success. None, however completely satisfies the requirements for a complete solution to the aforestated problem. The following U.S. Patents are attempts of the prior art to solve this problem.

     SUMMARY OF THE INVENTION 
     The present invention is defined by the appended claims with specific embodiments being shown in the attached drawings. For the purpose of summarizing the invention, the invention relates to an improved printed matter construction and method of making including a moving step article. The moving step article comprises an exterior cover having a hinge fold positioned between a front cover and a rear cover for pivoting the front cover between a closed position and an open position. The front cover has an obverse side and a reverse side. The rear cover has an obverse side and a reverse side. An interior leaf has an obverse side, a reverse side, an inner edge and an outer edge. The interior leaf defines a leaf width. A second interior leaf has an obverse side, a reverse side, an inner edge and an outer edge. The second interior leaf defines a second leaf width. The second leaf width has a greater width dimension than the leaf width. A spine sheet has an upper side, a lower side, an primary edge and an secondary edge. A primary hinge couples the primary edge of the spine sheet with the inner edge of the interior leaf. A secondary hinge couples the secondary edge of the spine sheet with the inner edge of the second interior leaf. The spine sheet, the interior leaf and the second interior leaf defines an integral one piece unit. A binder couples the lower side of the spine sheet with the reverse side of the front cover for defining a leaf offset dimension between the hinge fold and the inner edge of the interior leaf and a second leaf offset dimension between the hinge fold and the inner edge of the second interior leaf. The leaf offset causes the interior leaf to be displaced relative to the rear cover during pivoting the front cover between the closed position and the open position. The second leaf offset causes the second interior leaf to be displaced relative to the rear cover during pivoting the front cover between the closed position and the open position. The leaf offset dimension has a greater offset dimension than the second leaf offset dimension. The greater width dimension and the greater offset dimension create a step display tab area on the obverse side of the second interior leaf that is progressively revealed adjacent to the outer edge of the interior leaf during pivoting the front cover between the closed position and the open position. 
     In a more specific embodiment of the invention, a symbol is imprinted on the step display tab identifying a subject matter imprinted on the reverse side of the interior leaf and the obverse side of the second interior leaf. 
     In one embodiment of the invention, a back interior leaf has an obverse side, a reverse side, an inner edge and an outer edge. The back interior leaf defines a back leaf width. A back binder couples the inner edge of the back interior leaf with the obverse side of the rear cover for defining a back leaf offset dimension between the hinge fold and the inner edge of the back interior leaf. The back leaf offset causes the back interior leaf to be non-displaced relative to the rear cover during pivoting the front cover between the closed position and the open position. The back leaf offset creates a rear step display tab area on the obverse side of the back interior leaf that is progressively revealed adjacent to the outer edge of the second interior leaf during pivoting the front cover between the closed position and the open position. 
     The invention is also incorporated into the method of manufacturing a moving step article from a plurality of continuous ribbons of material using a line printing press. The method comprising the steps of inputting a first ribbon into the line printing press to define an obverse side of a front cover (A) and a reverse side of a rear cover (L) on a primary ribbon side and a reverse side of the front cover (B) and an obverse side of the rear cover (K) on a secondary ribbon side. A second ribbon is inputted into the line printing press to define a lower side of a spine sheet positioned between an obverse side of an interior leaf (C) and a reverse side of a second interior leaf (F) on a primary ribbon side and an upper side of the spine sheet positioned between a reverse side of the interior leaf (D) and an obverse side of the second interior leaf (E) on a secondary ribbon side. The second ribbon is perforated between the spine sheet and the interior leaf to define a primary hinge and a leaf width in the interior leaf. The second ribbon is folded between the spine sheet and the second interior leaf to define a secondary hinge and a second leaf width in the second interior leaf that is a greater width than the leaf width and positioning the reverse side of the interior leaf (D) adjacent to the obverse side of the second interior leaf (E). The lower side of the spine sheet is bound to the reverse side of the front cover (B) to define a step display tab area on the obverse side of the second interior leaf wherein the first ribbon is a non-folded position. The first ribbon is folded to define a hinge fold and positioning the interior leaf and the second interior leaf between the front cover and the rear cover. The first ribbon and the second ribbon is cut to length. 
     The foregoing has outlined rather broadly the more pertinent and important features of the present invention in order that the detailed description that follows may be better understood so that the present contribution to the art can be more fully appreciated. Additional features of the invention will be described hereinafter which form the subject of the claims of the invention. It should be appreciated by those skilled in the art that the conception and the specific embodiments disclosed may be readily utilized as a basis for modifying or designing other structures for carrying out the same purposes of the present invention.

     DETAILED DISCUSSION 
       FIGS. 1-10  illustrate a first embodiment of a moving step article  10 . The moving step article  10  may be referred to as a book  12  providing various purposes, including but not limited to, advertising, fiction material, nonfiction material, artwork or other written materials. The moving step article is preferably constructed from a cellulose pulp material, however the construction may further include polymeric or other thin material that may receive writing, printing, or drawing. 
     The moving step article  10  comprises an exterior cover  20  having a hinge fold  22  positioned between a front cover  30  and a rear cover  40  for pivoting the front cover  30  between a closed position  14  as shown in  FIGS. 2 and 3  and an open position  16  as shown in  FIG. 1 . The front cover  30  has an obverse side  32  and a reverse side  34 . The rear cover  40  has an obverse side  42  and a reverse side  44 . 
     An interior leaf  50  has an obverse side  52 , a reverse side  54 , an inner edge  56  and an outer edge  58 . The interior leaf  50  defines a leaf width  59 . A second interior leaf  60  has an obverse side  62 , a reverse side  64 , an inner edge  66  and an outer edge  68 . The second interior leaf  60  defines a second leaf width  69 . The second leaf width  69  has a greater width dimension  70  than the leaf width  59 . 
     A spine sheet  80  has an upper side  82 , a lower side  84 , a primary edge  86  and a secondary edge  88 . A primary hinge  90  couples the primary edge  86  of the spine sheet  80  with the inner edge  56  of the interior leaf  50 . A secondary hinge  92  couples the secondary edge  88  of the spine sheet  80  with the inner edge  66  of the second interior leaf  60 . The spine sheet  80 , the interior leaf  50  and the second interior leaf  60  define an integral one piece unit  94 . As best shown in  FIG. 9 , a binder  96  couples the lower side  84  of the spine sheet  80  with the reverse side  34  of the front cover  30  for defining a leaf offset dimension  98  between the hinge fold  22  and the inner edge  56  of the interior leaf  50  and a second leaf offset dimension  99  between the hinge fold  22  and the inner edge  66  of the second interior leaf  60 . The leaf offset  98  causes the interior leaf  50  to be displaced relative to the rear cover  40  during pivoting the front cover  30  between the closed position  14  and the open position  16 .

     Moving Steps Book Features:
         Unique, high impact, interactive concept   Magazine/Newspaper Insert, Self Mailer   Available in various sizes, including aspect ratio for mailing   Step size and travel distance is variable   8, 10 or 12 pages (2, 3 or 4 moving pages respectively)   Two pages per spine—pages lay flat, minimal image loss at seam   Pages can be contour die cut, individually die cut or straight edge   Cost effective, comparable to standard spine-glued, die cut books       

     Unlike any other spine glued book with conventional stepped pages, the Moving Steps Book features an automatic fanning of the pages as the book is opened. The reader actually observes as a portion (step) of each of the following pages is being revealed on the right hand side, ultimately creating a series of equally spaced page tabs. The movement of the pages is quite engaging to the reader since it is an unexpected, intriguing occurrence which encourages additional involvement. Also, the stepped pages are ideal for indexing the book&#39;s contents to facilitate the description of products or services. 
     Only two pages are attached to the multiple, widened glued seams which enable them to conveniently lay flat rather than having the usual and annoying tendency to close shut on the reader. This feature also eliminates most image loss found in other glue bound books. The appeal and function of this book can be further enhanced by die cutting with either a common to all pages (contour) or a page specific shaped die. 
     Manufacturing a Moving Steps Book is similar to producing conventional spine glued, static pages books and therefore should be comparable in cost. Traditional books are produced by gluing all pages to the center spread or fold line. Whereas this can necessitate more than one line of glue, depending on page count, all seams are placed on the same axis. The departure for a Moving Steps Book is to provide a gap between the glue streams at a distance of one half the desired page travel and resulting step size. Adding a perforation to each page parallel to, but not touching the glue stream, enables the pages to “break” (lay flat) rather than “fly” when the book is opened.
