Abstract: Flexible non-distortable handcraft sheet materials (78), including needlework fabrics, adaptable for receiving printed designs, patterns, photographs and craft instruc­ tional information and the methodology for producing the materials with the deisgns, patterns and photographs and instructional information printed thereon. Material alignment and feed features are located along the parallel edges of the materials for moving same through a computer-­ directed printer (76). In accordance with the methodology visual information in the form of designs, patterns, photographs, flat art work, still objects, live objects, etc. is converted into digital information through a digitizer (68) with the digitized image information thereafter fed to a computer (72) for manipulation and editing by software and keyboard (80) direction and for conversion to visual image information for CRT display (74) and for utilization by a computer printer as imprinted geographic information. The flexible handcraft sheet materials (78) bearing printer feed features include: paper and paper laminates; leather, suede, simulated leather, paper-leather and plastic-­ leather laminates; paper-thin woods, wood veneers and wood alminates with paper or plastic; laminates including non-woven, spun-bonded random fiber plastic sheet; plastic and paper-plastic laminates; foil and foil laminates; and like craft materials.

Description: 1. Field of the Invention The present invention relates to handcraft sheet materials. More particularly, the invention relates to needlework materials having for example a uniform pattern of apertures forming a symmetrical gridwork intended to receive needle-directed yarn or thread for the purpose of creating a stitchery design thereon and to other flexible handcraft sheet materials including paper, plastics, leather, wood and fabrics. The present invention further relates to materials of the type described for receiving printed designs, patterns, photographs and instructional information and to methods of printing designs, patterns, photographs and instructional information thereon. 2. Description of the Prior Art. a. Needlework. Embroidery is the art or process of forming decorative designs with hand needlework. When an open-mesh canvas or apertured sheet material having a uniform gridwork is used to receive the needlework, the art form is characterized as "needlepoint" or "canvas embroidery." Needlepoint is distinguished from other forms of embroidery, such as crewel embroidery, in that in needlepoint the stitches are formed by passing needle-directed yarn or thread through openings in the canvas or apertured sheet material in simple even stitches across counted threads or between counted apertures. Needlepoint canvas, in its simplest form, is comprised of evenly spaced, durable warp and woof threads woven into a textile in which the holes or apertures between the threads are commonly equal to or larger in size than the threads themselves. The canvas threads are usually composed of cotton or linen fibers, particularly where the gauge of the canvas (number of threads per cm/inch) falls within the popular range of 4-7 per cm (10 to 18 per inch). Fine gauge, needlepoint fabrics normally have 7-16 threads per cm.) (18 to 40 threads per inch) and are woven from silk or synthetic fiber threads in addition to cotton and linen fiber threads. Textile and fabric materials, manufactured for use as needlepoint canvas, are usually sold by their manufacturers in "bolt" (roll) units having a minimum of 5-10 yards (4.57-9.14 m) of material. The principal types of needlepoint canvases in use today are designated "mono-" meaning one thread on each side of each hole or aperture and "double" meaning two threads on each side of each major hole or aperture. There are two basic forms of mono- canvases, i.e., "mono-floating" and "mono-interlock." With mono-floating canvas the warp and weft (woof) threads are merely woven over and under each other whereas with mono-interlock canvas the warp threads (in fact) comprise two smaller (weaker) threads that are knotted or twisted at each over and under crossing of weft threads. Because of the weaving method, mono-floating canvases are subject to greater slippage between threads so that the mesh pattern of the canvas easily becomes distorted, i.e., the holes or apertures become of non-uniform size and configuration with repeated folding and needlepoint working of the canvas. Double thread needlepoint canvas (also referred to as "Duo" or "Penelope") is woven with the warp and woof threads that form the principal holes or apertures of the canvas each comprised of a pair of slightly spaced threads which form small apertures. This weave of needlepoint canvas is useful when it is desired to use half stitches or where petit point stitches (small) and gross point stitches (large) are to be worked on the same canvas. Other fine woven textiles used in the needlework arts include cloths woven so that the individual threads are thicker than the holes between them, "evenweave" cloth and "Congress" cloth. From time to time other forms of needlepoint canvas have been manufactured. For example, molded plastic, large gauge (4-15) mesh sheets, with a surface texture simulating the warp and woof thread configuration of woven needlepoint canvas, or with a smooth surface texture, have been made. Also, perforated paper sheets have been made and proposed for needlepoint projects of relatively small size where the resulting needlework is to be framed as a decorative item or where a free-form craft item is to be created using needlework techniques, i.e., book markers, greeting cards, etc. Mono-floating and mono-interlock needlepoint canvases have continued to be used for most stitchery applications despite their many shortcomings and the problems they create for the needlepoint artisan. The principal shortcomings and problems include edge raveling, canvas distortion, aperture irregularity and roughness, and thread shifting. Great care must be taken when cutting bolt or yardage canvas into smaller popular use size canvas pieces to make certain that each cutting course or line follows a single line of canvas holes or apertures, i.e., between warp and woof threads, so that edge raveling is minimized. Edge raveling becomes an even greater problem when the ultimate shape of the needlepoint piece is not rectangular with its edges not in parallel with warp and woof threads. Canvas distortion, stretching, sagging, extension and creep constitute major problems to persons performing needlepoint stitchery. If one closely observes needlework canvas as needlepoint stitchery is applied, it becomes obvious that the vertical and horizontal forces applied to the canvas threads (defining each aperture in the canvas) by the yarn-guiding needle and the yarn itself (as they pass through such apertures) are unequal. Although canvas manufacturers have attempted to reduce the distortion problem through the weaving of mono-interlock canvases and by the application of sizing (stiffening) agents to the canvas threads, the problem remains. Distortion correction, after completion of the needlework piece, by straightening or "blocking" the base canvas (and the needlework it bears) must overcome many built-in failure factors. Blocking, a somewhat costly procedure, involves the stretching and straightening of the needlework to its pre-stretched size and shape. An infinite number of decorative fabrics may be formed by applying needlework techniques to needlework canvas materials. These fabrics may vary widely in stitch type, yarn thickness, yarn colors, etc. Although some needlework artisans create their own stitchery designs while sewing a fabric or create a design on paper and reproduce it on the fabric, a primary source of designs is provided in kit form with the kit containing a pattern, the yarn types and colors and an appropriate canvas material, or needlwork patterns are sold independently. There are five principal variables associated with each needlework design, i.e., a) stitch types, b) stitch placement, c) canvas grid or mesh size, d) yarn thickness and e) yarn color. Yarn thickness and canvas mesh size can be readily indicated by simple directions on the pattern while stitch types, stitch placement and yarn color directions are more difficult to indicate. Where fine embroidery on linen or other fine mesh material is to be performed by the artisan, the design or pattern may be printed, drawn or painted on (or transferred to) the fabric and the artisan merely sews over the design or pattern. With needlepoint designs, stitch type variation is usually involved. Further, since the commonly used canvas types (10 to 18 mesh) are substantially air space (apertures greater than canvas thread thickness), printing of stitch type instructions is not feasible since most stitchery is directionally oriented. Also, the present-day woven canvas materials are distortable and not perfectly true in mesh or grid structure and when design printing thereon is attempted, the design frequently does not properly align with the gridwork of the canvas with the result that stitch type location is faulty. Only thread-by-thread hand painted designs are true and they are very time consuming and costly to produce. In view of the foregoing state-of-the-art in needlework stitchery, popularly priced designs are most commonly shown on separate charts indicating the specific location of stitch types and yarn colors on a line gridwork representing the canvas gridwork. In using these charts, the needlework artisan must refer to the chart before applying one or several more stitches. Constant back-and-forth cross-reference between the chart and the needlework piece is necessary. In document US-A-4 090 300 to facilitate embroidery work on a canvas, a pre-printed sheet of material of substantially smaller area than the canvas is prepared having a gridwork printed thereon that should correspond to the gridwork of the canvas and, in addition, it has indicated thereon the stitches and the locations of stitches to be needlepointed on said canvas to form a selected stitch pattern. The sheet has on one face a pressure sensitive removable adhesive by means of which the user of the sheet can apply it to an area of the canvas to be worked upon. b. Leatherwork. Leatherwork encompasses the cutting, tooling and burning of decorative designs in leathers, tanned leathers, suede materials and a wide selection of imitation and simulated leather materials. Also, leatherwork may include handcraft design work that involves such materials in design punched or cut forms with the addition of a variety of attached media and adornments. As in the case of needlework, it is desirable to apply designs and patterns to leather and leather-like materials for their instructional utility in the performance of cutting, punching, tooling, burning, and adornment handcraft procedures and for their nonfunctional decorative effects. c. Paperwork. Numerous handcraft ideas have been suggested and developed involving the use of paper, construction paper, flexible paper board and like materials. Again, designs and patterns are frequently applied to these materials in their flat, pre-crafted state as instructional information and as decorative design matter to add to the overall visual effect of the finished handcraft item. d. Woodcraft. Thin, flexible sheets of wood, wood veneers and wood-simulated plastics have come into popular use in the handcraft arts. As with leatherwork materials, wood and wood-like materials used in handcraft projects usually require the application of decorative design and pattern instrutional information for use in the performance of cutting, punching, burning and mixed-media application procedures and for adding to the visual appearance of the final craft item. e. Plasticwork and Foils. The wide variety of flexible sheet plastic materials and foil materials in a full range of colors and tints have made such materials highly desirable for handcraft projects. Metalized plastic mosaics in flexible sheet form are, for example, being used as a craft medium for making fashion accessories including belts, necklaces, rings and pendants. The need for the imprinting of designs and handcraft patterns on these types of materials is increasing. SUMMARY OF THE INVENTION According to one aspect of the present invention there is provided a flexible but non-distortable handcraft sheet material having a print receiving surface on at least one side thereof capable of receiving computer-generated print designs, patterns, and photographs as craft instructional or decorative visual information for use in creating finished handcrafted items incorporating the printed areas of said sheet material, wherein said handcraft sheet material has alignment and feed means located along the edges thereof for positively guiding and moving said material through a computer-directed printer for imprinting a design, pattern or photograph on the print receiving surface thereof, and said handcraft material consists of a primary layer of a material selected from the group comprising: woven needlework canvas; paper; leather, suede and simulated leather; paper-thin woods, wood veneers; plastic sheet materials; foils; and a secondary layer of sheer non-woven, semitransparent random-spun synthetic fibre material permanently or temporarily bonded to the primary layer; and any one of the foregoing handcraft materials pretreated with coatings to improve image printing receptivity, color, detail or density. In the case where the primary layer is a woven needlepoint canvas, this is preferably mono-floating or mono-interlock. Also in the case of woven needlework canvas the shearness of the secondary layer is preferably such that the holes or apertures of the canvas remain distinct to the needlepoint artisan as well as the secondary layer being thin so that it is easily penetrated by the yarn bearing stitchery needle. Optional features of this aspect of the present invention are set forth in the claims that are dependent on Claim 1 below. According to a second aspect of the present invention there is provided a method of producing handcraft sheet materials comprising the steps of a) digitizing an image consisting of the design, pattern or photographic subject matter to be applied to the handcraft sheet materials to convert the visual image information respecting said design, pattern or photographic subject matter into digital image information; b) feeding the digital image information to a computer; c) feeding a handcraft sheet as defined in the appended claims to an electronic printer, said sheet material presenting a surface adaptable for receiving imprinting thereon; and d) printing the selected handcraft design, pattern or photographic subject matter comprising the visual image information on the print surface of said sheet of handcraft material via the electronic printer as directed by said computer. Optional features of this aspect of the invention are defined in the claims dependent on the independent method claim below.

PREFERRED EMBODIMENTS OF THE INVENTION Referring initially to FIGURES 1, 2 and 3 and to their respective segmental enlargements FIGURES 1a, 2a and 3a of the drawings, there is shown examples of the apertured and perforated needlework materials of the invention which are adaptable for receiving computer-generated printed needlework designs, patterns and photographs. In FIGURES 1 and 1a the apertured needlework material is a composite laminated needlepoint canvas material 10 comprised (as particularly shown in FIGURE 1a) of a non-elastic, open-mesh woven needlework fabric primary layer 12 including warp threads 14 and weft threads 16, which has bonded directly to one of its faces a relatively thin, non-elastic, mesh-stabilizing secondary layer of sheer fabric material 18. The composite laminated needlepoint canvas material 10 may be any of my improved flexible, non-distortable composite laminated sheet materials as described hereinbefore. These materials all present on their sheer fabric side a relatively smooth surface adaptable for receiving imprinted designs, patterns or photographs. Along each parallel edge 10a and 10b of material 10 are located a line of uniformly spaced pin holes 10c and 10d, respectively, which penetrate material 10 and correspond in size and edge spacing to the standardized pin-feed (tractor) drive mechanisms of the many well-known computer-directed printers. Such printers commonly handle paper widths of 10-39 cm. (4 to 15.5 inches) and special printers are available which accept paper widths of as much as 122 cm (4 feet). Thus, in accordance with the present invention needlework materials of varying widths, and presenting a printable surface, may be fabricated with edge pin holes for moving such materials in positive drive through a computer-directed printer or the materials may be provided with side bands for frictionally moving same through a printer. In FIGURES 2 and 2a the needlework material is a composite laminated material 20 comprised (as particularly shown in FIGURE 2a) of a non-elastic, heavy, perforated paper primary layer 22 including uniformly spaced perforations 24 forming a grid of perforations for receiving needlework stitchery, which has bonded directly to one of its faces a relatively thin, non-elastic secondary layer of sheer fabric material 26. The sheer fabric side of the laminated material 20 presents a relatively smooth surface adaptable for receiving imprinted designs, patterns and photographs. Along each parallel edge 20a and 20b of material 20 are located a line of uniformly spaced pin holes 20c and 20d, respectively, which penetrate the material 20 and receive the standardized pin-feed drive mechanisms of computer-directed printers. In FIGURES 3 and 3a the needlework material is a composite laminated material 30 comprised (as particularly shown in FIGURE 3a) of a non-elastic, extruded plastic, woven open-mesh needlework primary layer 32 including simulated warp components 34 and simulated weft components 36. The primary layer 32 has bonded directly to one of its faces a relatively thin, nonelastic secondary layer of sheer fabric material 38. The sheer fabric side of the laminated material 30 presents a relatively smooth surface adaptable for receiving imprinted designs, patterns or photographs. Along each parallel edge 30a and 30b of the material 30 are located a line of uniformly spaced pin holes 30c and 30d, respectively, which penetrate the material 30 and receive the standardized pin-feed drive mechanisms of computer-driven printers. As previously indicated, apertured and perforated needlework materials of the invention may be provided in a variety, of common printer widths ranging between 4 to 15.5 inches and in special situations in substantially greater widths. Preferably the material is supplied in bolts of several yards or more and fed from a spool into the computer-directed printer because of the thickness of the material and its stiffness as compared to common printer paper. Where the needlework material of the invention is reasonably flexible and relatively thin it may be fed to the printer as fanfolded material. Individual packets of separate pre-cut sheets of the needlework materials may also be fed to the printer. The edge strips of the needlework material including the pin holes may be cut away from the material after it has received the imprinted subject matter. Alternatively, the pin holes may be utilized as mounting means for the finished needlework item, or means for connecting the finished or unfinished needlework item to another correlant craft material or craft construct. In FIGURES 4 and 4a the craft material is a sheet 40 having a primary layer of leather, tanned leather, suede or simulated leather, craft paper or craft plastic foil, paper, paper thin woods or wood veneers and a secondary layer of sheer non-woven, semitransparent random-spun synthetic fibre. The primary layer of material 42 of sheet 40, as shown, includes various sizes of punched holes or perforations 44 forming a design of perforations leaving large material surface areas for the imprinting of designs and crafting instructional information. The primary layer material 42 may be permanently or temporarily bonded to a secondary layer of material (not shown). Thus, the primary layer may be carried by a secondary release non-woven fabric material bearing a release adhesive and the computer-directed imprinting may be applied to the secondary layer of non-woven, fabric material or to the primary layer 42. Along the parallel edge 40a and 40b of material 40 are located a line of uniformly spaced pin holes 40c and 40d, respectively, which penetrate the material 40 (layer 42 and the secondary layer) and receive the standardized pin-feed drive mechanisms of computer-directed printers. The design or pattern imprinted on material 40 may be instructive as to crafting steps to be taken (cutting, tooling, punching, burning, coloring, affixing, etc.), may provide non-functional decorative art work on the material, or may be functionally related or interrelated to other craft materials or craft constructs forming a part of the material 40 or to be matched to or associated with such material. In FIGURES 5 and 5a the primary layer of the craft material is a flexible sheet 50 of plastic pieces 52 forming a mosaic arrangement mounted on a self-adhesive layer 54 (see FIGURE 5a) protected by a secondary backing layer (not shown). The plastic pieces can be scored and bent for crafting purposes and are adaptable to printing for the receipt of designs and patterns. Along the parallel edge 50a and 50b of material 50 are located a line of uniformly spaced pin holes 50c and 50d, respectively, which penetrate the material 50 (layer of plastic pieces 52, self adhesive layer 54 and backing layer) and receive the standardized pin-feed (tractor) drive mechanisms of computer-directed printers. Referring now to FIGURE 6 there is shown in somewhat diagramatic fashion the methodology of applying designs, patterns, photographs and craft instructional information to a print surface of one of the handcraft materials of this invention. For purposes of describing the methodology, the handcraft material illustrative thereof is a flexible, non-distortable needlework material comprised of a laminate of open-mesh woven needlepoint fabric which has bonded to one of its faces a relatively thin secondary mesh-stabilizing layer of non-woven, semi-transparent (sheer), random-spun, synthetic fiber material, the secondary layer providing this handcraft material with a print surface for receiving printed design, pattern, photographic and/or instructional information. As previously mentioned, the methodology of the invention for producing needlework and other craft materials bearing designs, patterns, photographs and craft instructional information comprises the utilization of digitized images of designs, patterns, photographs, still objects, live objects, etc. (the subject matter for needlework stitchery) which are computer-directed to a printer. The printer is fed with the flexible, non-distortable sheet handcraft material (needlework material, etc.) of the invention with its print receiving surface. In accordance with the methodology the visual information (the design subject matter) is converted into digital information through a digitizer. As shown in FIGURE 6 the digitizer may be of either the video type 60 utilizing the standard video signal information from a video camera 62, a video cassette recorder 64 or a video disk player 66 (fed to digitizer 60 by their respective transmission cables 62a, 64a and 66a) or the optical type 68 utilizing a light emitter and detector unit 70 with the optical signal information fed to digitizer 68 via transmission cable 70a. All digitizers convert visual information into digital information by breaking down an image into a mesh of fine dots and assigning a specific numerical value to the gray level found in each dot. Video digitizers use standard video signals created by scanning flat designs, photographs, and three-dimensional objects (still and alive). As shown in FIGURE 6 video camera 62 is scanning a flat design D. Optical digitizers, through their emitter-detector system of present day design, scan only photographs, illustrations or other flat artwork D. The emitter projects a tiny beam of light onto the flat image and the light sensitive detector senses the degree of lightness or darkness in each dot of the image as the beam goes over it. Thus, optical digitizers base their generated digital information on the light beam's reflection value. A video digitizer turns the video signals it receives into a stream of binary numbers, reducing the light intensities represented by the video signal to a high-contrast image which a computer can represent digitally. The digitized image information derived through a video digitizer 60 or by an optical digitizer 68 is fed through transmission cable 60a or 68a, respectively, to any one of the many available types and models of personal computers represented in FIGURE 6 as micro-computer system unit 72. The micro-computer 72 converts the digital image information into visual image information and transmits same via cable 72a to a CRT display unit 74 (black and white or color picture) for viewing. The digital image information is also utilized by micro-computer 72 to direct a printer 76 of either the dot-matrix or laser type to print out (black and white or color) the visual image information on the flexible, non-distortable handcraft material 78 of the invention. The readily available and less expensive dot-matrix printers create visual images by producing a series of dots laid out on a grid pattern. These dots are produced by one of three printing methods, i.e., impact, thermal or ink-jet. Computer direction of printer 76 is accomplished via transmission cable 72b and the computer is responsible in its transmitting of display information to CRT display unit 74 and printout information to printer 76 to the commands generated by keyboard 80 (through cable 80a) and graphic and artistic software programs and menus supplied to the computer. Through a number of available computer software programs the digitized image information relating to a given design, pattern or photograph may be manipulated by, and edited through, keyboard direction. A pattern line grid can be created that corresponds in mesh size to the line gridwork formed by the threads of needlework canvas materials upon which the computer-aligned and computer-directed printing of a design, pattern or photograph is to occur. The computer-created line grid may be displayed by the CRT unit with the visual image proposed for needlework handcrafting displayed in superimposed fashion thereon. The displayed image may be shifted over the displayed line grid for alignment purposes and the image (if video originated) may be block pixelized to render it as a mosaic pattern matched to the squares within the line grid (corresponding to the needlework apertures) or to cross points of the line grid (corresponding to the thread cross points of the needlework material). An image may be "zoomed" down and then"zoomed back up to its original size. This process squeezes information out of the image and then displays the image in its lower resolution and thereby more obvious pixel shape, "posturization" can further enlarge the pixel groups and create abstracts of an image. With optical digitization the generated pixels are generally rectangular so that only blocks of pixels can be made to be exactly aligned with the square gridwork of needlework canvas materials. Thus, computer technology and aesthetics are merged and displayed. The computer image pixels, like the needlework apertures, are an array of small squares which build into a larger picture or geometric design. Placing these pixels exactly in line with or within the screen grid (and thus the needlework grid) allows the computer-directed printer to print a mosaic-like picture on the sheer print surface of the needlework material in alignment with the apertures of the woven primary layer of such material. This makes possible the merger of user-friendly printer interfacing off the computer screen canvas of mosaic computer imagery onto the printer-fed classic woven textile craft form of needlework canvas imagery. Herein, the modern computer signature translates with precision onto the ancient needlework artforms. The foregoing transposition of visual images into digital information and back, via computer technology, to printed imagery in exact alignment with the gridwork of the needlecraft materials of the invention equals and supplants the need for costly hand painted needlework materials. Furthermore, the methodology of the invention eliminates the tedium of back-and-forth reference between needlework material and craft chart guidelines and stitchery information. Through a number of software programs, artistic and color on-screen designing changes can be made with respect to the CRT displayed image and unique effects can be created and thereafter printed out on the needlework or other craft materials of the invention. Thus, image zooming, shifting, rotating, mirroring, stretching, shrinking, transposing, color cycling, color enhancing, mating, multiplying, etc. can be accomplished through software and keyboard direction. After finishing image manipulation as viewed on the CRT screen, the displayed image information (with or without a computer-created line grid matching the needlework grid) is computer-directed to the printer for imprinting on the needlework or other craft material as fed through the printer with the result that the visual printed image, produced by the printer, is in symmetrical alignment with the gridwork of the needlework material or in synchronized positioning on the print surface of these and other craft materials. In the case of needlework designs, computer-generated grid outlines can be rendered in any number of different pattern choices to match the particular material to be imprinted. For example, dot grid symbols can be established and embellished in precise dot alignment with the perforations of the needlework paper material of the invention bearing a non-woven laminate backing providing a full print surface. Further, grid symbols can be chosen and supplied in the printed image which exactly match the slant of stitch directions. It will be apparent through the foregoing descriptions of the handcraft materials of this invention and of the methodology of the invention (described for the most part in connection with unique needlework materials) that a multitude of craft materials can now be made available which bear printed designs, patterns, photographs and instructional information. The printed matter is applied to the craft materials in exact alignment with the features of the materials (gridwork, slits, cut-outs, pasteons, perforations, etc.) so that the artisan can readily create a superior crafted item with the printed matter incorporated therein as the functional, directional information for accomplishing the crafting and/or to provide non-functional visual decorative effects in the crafted item. The means for feeding the handcraft materials of the invention through a computer-directed printer often may serve as a functional feature of the crafted item, i.e., mounting, binding, edging means and the like. Where required by the nature of the craft type, the material may include a carrier material such as release paper or non-woven fabric material leaving the ultimate print-bearing craft sheet adhesive free or leaving the craft sheet with pressure sensitive adhesive coating for mounting purposes.
