Abstract

A kind of book being made up of plastic sheet, plastic sheet, which is made on a side (47), forms lenses, and lenses, which are printed directly on the side relative with eyeglass or lenses, has the print page for being laminated to the side relative with eyeglass.When being watched by eyeglass, lens printing allows the page to show virtual three-dimensional and/or animation effect.Book is configured so that the page can be placed with flat, it is allowed to which all 2 pages in the case of being deformed caused by center groove (47a) generally by not watched.Semi-rigid lenticular sheet is stacked in substrate (47b) and is folded along the center line (49) for creating double spread (48).Each double spread is combined together into doubling page (48a)：Single double spread is glued or stacked together and binds into book structure, so as to form the page of book.Stiffener is commonly added at the spine of doubling page, for increasing intensity and visual appearance (50).Then front cover (traditional hard front cover or softcover or unconventional lens front cover) can be attached directly to behind first page and last page, or is attached at by using traditional title page on the lens of unconventional pair of pages width.

Description

Lens book

Method for the lens of printing to be prepared into and bind into complete book.

Technical field

Printing, the making of book.

Inventor

Qiao Enganmo Nice.

Background technology

The present invention relates to a kind of method for lenses being configured to and being bound into book.The book allows from difference The angle viewing page when picture showing that prints be with three dimensional depth and/or animation effect.This method is related to the " flat of bookbinding Dress " method, thus two pages can all be seen.But the method use entirely different building method

Make us impression with outstanding market attractiveness and advertising appeal there is provided the process of high-efficiency and economic to produce Deep books.In this process, multiple images formation is in such as CPU, and image has striped or is manipulated, and disappears The pixel from other images, and the partial stack (being referred to as " interlocking ") of image are substituted for except pixel column and by them.It is folded Plus image can be printed on the visible surface of display.Lenses, Fresnel Lenses eyeglass plate, with grain surface Eyeglass, plate eyeglass, UV-cured resin eyeglass, the eyeglass with undercutting, deformation eyeglass group, transparent rods or grid (here It is referred to as " lenses ") front of image can be placed on to provide Special display, the Special display when visual angle changes Illusion with animation, deformation, motion or three dimensional depth.Image can also be printed directly on the back side of eyeglass, to provide Independent lens figure.

This method has been invented so that book can be placed when opening with flat, it is allowed to cross-page in correctly watching (if Need), and bound, then using spiral binding or traditional thread binding ordered using method in addition to punching or drilling, it is allowed to Full-scale front cover (lens type is traditional) is attached, and full-scale front cover includes front cover, spine and rear front cover.Although similar to Paperback method, but the present processes are all unique in design and construction.

The present invention relates to the method for printing or non-printing lenses to be bound into books form.Lens paperback Book is different from typical paperbound, and its reason is that lens paperbound is made up of the single doubling page being combined together, described Doubling page does not share common base.By comparing, traditional paperbound or paperback volume use multiple four foldings or 4 pages Constitute, 4 pages are combined together in the form of two doubling pages of common base are shared when to combine.Traditional paperbound Difference is also resided in, and printing image is located on single paper and is laminated to two substrates for being individually used to bind.Lens paperbound Using different methods, thus image is printed on two single hard lenses pieces, and hard lenses piece is layered in for filling In the single substrate ordered.

Lenses for semi-rigid and when bind multiple when generate certain challenge.The present invention is handled and solved many Individual problem.Such a problem is that then the page flat can not be placed when opening once " traditionally " binds.But former The method for having used punching, cut hole or drilling in lens for the technology that multiple lens pages are made into book, Ran Houtong Cross that spiral, ring or line are stapled together by piece, this method solve these problems and there is provided unique scheme.This method allows Lens is bound in the way of being bound similar to hardback, such as, but not limited to, hard-cover, single page locking wire is followed closely, Smith binds, The happy bookbinding of two-sided fan-shaped mucilage binding, dimension, advanced click (Proclick) bookbinding, slide fastener bookbinding, hot melt binding, library's bookbinding, glue Band bookbinding, excellent easy companion's bookbinding, locking wire bookbinding, perfrct binding, saddle stitching etc..This method also allows interior cross-page design, interior cross-page to set Meter is presented as across the printings of page two for including edge and groove and book can be opened flat to viewing.

Paperbound

But the impressing book of standard lacks image in groove, all paperbounds use " flat to place " design, it is allowed to Panorama sketch crosses over page two (being referred to as " page two " or " interior cross-page ").It is traditional to be opened flat book or be opened flat volume, with or without leap The image of the scraps of paper (or the similar printing material) printing of pair of pages width, is scribed along the center for being used to fold.Then the piece quilt The individual hard substrate in two (2) is laminated to, these substrates Bu centers are combined together, therefore allows the page of printing to be rolled over along line It is folded.Therefore, substrate then is combined, then the relative page can share single substrate, is then filled using traditional library Binding method is stapled together.Method for producing lens book is different from traditional method on many key ways.

Lens paperbound

By lens bind into paperbound or paperback volume method used it is entirely different with traditional paperback method for stitching Building method, this method allows two pages for facing to be placed by completely flat, and image can be interior cross-page as leap One continuous panoramic picture is watched, and center or " groove " place do not have the missing of image.

For the thick or thicker lens of 0.5mm, new method needs the single lens page (for semi-rigid) to be laminated to The scraps of paper of pair of pages width or similar substrate, including plastics, film or cloth (non-rigid), and the scraps of paper or substrate be scribed in center To allow to fold.The page (or " interior cross-page ") of double-width is more slightly wider than twice of the width of single lens piece.The reality of substrate sheet The width of border width and two lens of combination and extra identical apart from sum, it is single that extra distance is calculated as using Twice of minimum value of lens thickness.Increase the extra distance there are enough spaces to allow cross-page in construction drawn Line and folding；Therefore " individual unit " or " double spread " is formed.Then the combination of single double spread uses traditional books Shop method for stitching is stapled together as book.

In order to realize the visual appearance (that is, across the panorama sketch of two pages) for being similar to traditional paperbound, apply The piece of lens panel can proportionally be printed with identical image in center, when two lens panels are placed on one shoulder to shoulder When rising, the image occurs therewith.When the flat opening of the page, because image is directly printed on base material, positioned at two again Reserved spatially between individual lens panel, so image will provide the outward appearance for a consecutive image for crossing over two pages.

It is less than 0.5mm lens for thickness, the lens of single pair of pages width is used and uses the line of heating Blade is rule at center.The line reduces the thickness of lens, it is allowed to bigger flexibility and therefore piece can be rolled at center Fold to create double spread.Double spread can be laminated to substrate to bind doubling page to front cover and/or to give double spread certain Intensity.

Unlike traditional method, common base is shared without lens.Therefore, school bag includes single double spread and (is referred to as " doubling page ") combination.Doubling page is laminated on together the internal pages to form book and can used traditional Library's method for stitching.Whereby, the spine of internal pages is extraly reinforced by fabric or the similar object for being referred to as " stiffener ". Internal pages are so completed, internal pages are then attached to front cover using traditional method for stitching, otherwise it is attached to hard Or front cover is attached to softcover.

Hard front cover is bound into, title page can be used, the thin decoration that title page includes printing is used with printing lens piece or decoration Printing or non-printing paper, internal pages are bound to by front cover.Title page is generally slightly less than the size of hard front cover.

When bookbinding is to softcover, softcover can be made up of single lens piece, and the lens is scribed, that can fold Repeatedly allow front cover entirely around internal pages.If softcover is more than internal pages during constructing, and/or when the page exists After bookbinding during out-of-flatness, whole book can be trimmed to change size.

This method is adapted to but is not limited to print and manufactures illustration book, comic books, picture novel, children's books, shooting book, the fine arts Book and design sheets.

Bind history

By the way that several stackers of doubling are sewn on band or rope together, for protection book and the dress of the purpose for the outward appearance for improving book The technology of ordering experienced several centuries, by least a portion of overlay planes or the back side of the leather of seam or cloth, and band or knot are closed To the paper-board planar of the side of covering book, then gluing has decoration title page in plane, and plane is in itself covered with various decoration materials Material.

This Traditional Man method is probably reappeared by using the industrialization method for stitching of time-saving simplified step, letter Changing step plays the role of to keep production cost to decline, but can cause with short-life quite rudimentary product.The main body of book The folio got up by seam is formed, therefore is dividually made before inserting or being glued to the front cover formed by plane and the back side It is standby.On the other hand, the back side of the book with this bookbinding form is usually provided with firm fiber packing, thus given book some Rigidity, result is that book easily flat can not be opened.Which results in the inconvenience of reading and the inconvenience of viewing photo duplicate.

The application be used for by lenses bind into book method allow the page by it is flat opening and front cover with unlike The mode of any methods availalbe is manufactured together with book.

Lenses

Lenses are cylindrical planoconvex lens array, are designed to when from slightly different angle viewing, different figures As being exaggerated.Most common example is the eyeglass used in lens printing, and the technology is used to that figure ought to be watched from different angles During picture, give plastic or make picture showing to change or move.The image of printing is applied directly to lenses or printing On paper, on plastics or other materials and it is laminated to the downside (Fig. 2 .2) of eyeglass.Lenses can vertically, horizontally or Run (Fig. 1 .2) at any angle.

Lens printing process

Lens printing is such technology：Lenses are used to produce below figure picture, when watching image from different angles When, image has the illusion of three dimensional depth or with the ability for changing or moving.It is three-dimensional that the example of lens printing includes display The printing image of depth effect, upset, scaling and animation effect, the eyes and modern advertising figure of these effects such as blink Shape, changes their message according to visual angle.This technology was created in 1940s, but was grown up in recent years, table Reveal more motions and increased depth.Initially used mostly in novelty article, be commonly known as " flicker picture " or " shake Put picture ", present lens printed matter is used as marketing tool so as to virtual three-dimensional space and/or with two dimension or three-dimensional motion Mode shows product.

Lens printing is multi-step process, including from least two image creation lenticular images and by image and lens mirror Piece is combined.The process can be used for creating multiple animation frames (being used for movement effects), multiple layers (is used with different delta offsets In 3-D effect), or one group of alternate image is simply shown, this group of alternate image can appears as mutual conversion.Once it is many Individual image is collected, then image, which becomes flat, turns into single different frame file, is then counted during being referred to as staggeredly It is combined into single definitive document word.From this, interlaced image can be printed directly to eyeglass the back side (smooth side) or It can be printed in substrate and be laminated to eyeglass.When the back side of printing to eyeglass, tiny " part " of interlaced image Crucial alignment must completely be corrected during lithographic printing or screen printing process, otherwise can cause " ghost image " or figure inferior Picture.By changing the angle that printed matter is watched, with reference to lens printed matter will show two or more different images.If Obtain in order, using more images, then printed matter even can show the short-sighted frequency of about one second.

Although being produced generally in the form of piece, by making simple image or different colours on whole picture interlock, Lenticular image can also be created in the form of the volume with 3-D effect or polychrome change.Alternatively, it can use from somewhat The several images for the same target that different angles is obtained, then create the lens printed matter for showing stereoscopic three-dimensional effect.It is three-dimensional Effect can only be realized in the direction (from left to right) from side to opposite side, because the left eye of beholder is needed compared with right eye Stereoeffect is realized from a slightly different angle to watch.Other effects, such as deformation, motion and zooming effect will be with The effect effect (eyeglass level run) from top to bottom preferably carries out (less ghost image or potential effect), but can be Realized in both direction.

Lenticular image has many commercial terminal purposes, and lenticular image can be poly- to benzene by polyvinyl chloride (PVC), amorphization Naphthalate (APET), acrylic plastics and polyethylene terephthalate (PETG) and other materials are made. And PETG and APET is most common material, increase of the other materials due to lenticular image on cup and Gift Card is used, and is become Obtain popular suitable outdoor use and specially-shaped.It is straight that lithographic plate, hectograph and the printing of soft version lens allow the planar side of lens to have The ink being placed on eyeglass is connect, and high-resolution photographic lens generally has the image for being laminated to eyeglass.

Newest lens technologies are to utilize soft version, ink-jet and screen printing technique manufacture eyeglass.Lens materials come from volume Or piece, by soft version or hectographic printing system to be carried out at high speed supply, or (being typically can be accurate using UV ink jet machine The level bed of alignment) printing.This technology allows with low cost production high power capacity three-dimensional lens.

Embodiment

Lens book is different from typical paperbound, and its reason is lens book by being folded into two units of pages or " doubling page " It is single single composition, two units of pages or " doubling page " are combined together back-to-back.These doubling pages do not have Share common base.By comparing, traditional paperbound or paperback volume use multiple units that common base is shared when combining Constitute.The difference of traditional paperbound is also resided in, and image printing is on the single scraps of paper and is laminated to two individually for binding Substrate.Lens paperbound uses different methods, and thus image is printed on two single hard lenses pieces, then firmly Matter lenticular sheet is stacked in the single substrate for bookbinding.

Now referring more particularly to methods described, Fig. 1, Fig. 2 and Fig. 3 depict the top view of lenses.The side of eyeglass To that can be any angle and the direction of the complete alternate angle according to image, the image be using software generation and is directly printed on On mirror eyeglass or it is laminated to lenses.

With reference to Fig. 4, Fig. 4 depicts the section for the lenses mentioned in Fig. 1, Fig. 2 and Fig. 3, shows independent lens Or the array of eyeglass (1), the plane of delineation is below lens or eyeglass (1), on relative surface, wherein relative In surface, image is printed directly to lenses (2) or is laminated to lower section, and image is (3) and visual by eyeglass (4) upwardly.

The figure of page 2, shows stereogram and depicts between Fig. 5 conventional printed book and Fig. 6 typical paperbound Comparison, they all it is flat place cause the page in the on-state.But the impressing book of standard lacks image in groove, institute Some paperbounds use " flat to place " design, it is allowed to which panorama sketch crosses over page two (being referred to as " 2- " or " interior cross-page ").With reference to figure 5, in conventional printed book (5), the page is combined in center (6), and image is printed as across the two visual page (7) panoramas Ground shows, and image disappears in the position for being referred to as trench region (8), and therefore have impact on the overall appearance of image, image it is whole External see should continuously be seen across two pages in the case of not any visual deformation originally, but herein show The physical deformation as caused by forwarding (9).

Fig. 6 shows the three-dimensional view of the paperbound in open mode, and wherein the page (10) is flat places.Paperbound Typical structure allows to continuously see across two pages in the case of any missing or visual deformation of no image (11) Image.

Fig. 7 outlines the standard method in the front construction page for binding into paperbound.All paperbounds are put using flat Meter is installed, this allows across the interior cross-page continuous panoramic picture of printing, and sees figure in the case of not any anamorphose Picture.(12) depict the print page with upward image-side herein, then using the bonding material for combining print page (12) Print page is laminated to two substrates (14) than print page more hard by material (13).The page of construction is along center line (15) quilt Groove and in face of the page to interior folding.Two substrates are not combined at center, alternatively, leave the small―gap suture labeled as (16) To facilitate folding process.

Fig. 8 refers to the page constructed in Fig. 7, is the sectional view of internal pages.Fig. 8 refers to Fig. 7, depicts the interior of paperbound The typical method for stitching of portion's page, is attached to interior cross-page (17) of substrate (18) and is scribed along line (19) and itself faces the page Inwardly (20) are folded, so as to create two pages.It is common base 21) that the page of printing, which can share mark,.Other Page marks are (22), are to fold the page or four foldings, and folding the page or four foldings can be constituted and be shared public by 4 pages Substrate.It is then possible to using typical " library's bookbinding " method that four folding is stapled together, thus stiffener, woven cloth Or the like (23) attachment (24) to construct the page folded edge so that by page binding together.Then, it is hard or soft Front cover bind to the page, front cover can also be trimmed to complete book construction (detailed description of the process does not form this Shen A part please, is deliberately eliminated).

The figure of page 4, shows stereogram, the stereogram is depicted by the typical paperbound and Figure 10 sheet in Fig. 9 Obtained difference is compared between the lens paperbound of application.Fig. 9 shows the plane (25) that typical paperbound is opened, figure As crossing over two page prints on single, it is allowed to see continuous image, do not have any vision at center (26) place and become Shape, Pian centers (27) place of printing is scribed to allow to fold.By comparing, Figure 10 depicts the lens paperbound of the application And stereogram when showing flat placement.This is made up of two lens (28) for being laminated to flexible substrates (29).To be formed Two pages.Slot milling (30) between lens, so that the substrate (29) that they are laminated to thereon can be along center (31) It is scribed and folds, promotes the page folding opened if folding into two pages, so as to create single two pages list Member, otherwise known as " double spread ".

Core (such as Figure 12 to 14 tables that the image (32) created by the space (30) between two lens is lacked Show, during manufacture must be to be folded into the double spreads of page two by single) substrate material can be directly printed on before manufacture Expect on (29), so as to give similar to the continuous, continual of traditional paperbound with reference to Fig. 9, panoramic picture (33) Illusion.Printed substrates present image from the part of interior cross-page " missing ".When the flat opening of the page, it will provide and cross over two The outward appearance of a consecutive image (33) of the page is opened, " missing " part of whole image is actually printed on two lens faces again Between plate spatially.

The figure of page 5 depicts the more detailed sectional view with reference to Figure 10.Bind into lens paperbound or lens paperback volume Method, has used the building method for being totally different from traditional paperback bookbinding.Figure 11, which is shown, describes the more detailed of the new method Sectional view, this method needs the single lens page (34) of hard to be laminated to the scraps of paper of pair of pages width, or including plastics, film Or the similar substrate of cloth (35), the substrate for non-rigid and be scribed in center (36) with allow fold.The reality of substrate sheet The width of border width and two lens of combination with by " h " represent it is extra identical apart from sum, the developed width is layer The minimum value of the thickness of each single lens piece (37) of substrate is stacked to, in this case for twice or " 2 × h " (38).Increase Plus the extra distance is to there is enough spaces to allow cross-page to be scribed and fold in construction；Therefore formed individual unit or " double spread ".

In order to realize the visual appearance for being similar to traditional paperbound with reference to Fig. 9, Figure 11 shows more detailed section Figure, whereby, identical image can be proportionally printed with center (38) place by applying the piece of lens panel, if two saturating Mirror board covers the same area of printed substrates, then the image occurs therewith.When the flat opening of the page, it will provide and cross over two The outward appearance of a consecutive image of the page is opened, because " missing " part of complete image is actually reprinted at two Between lens panel spatially.

Unlike traditional method (Fig. 6, Fig. 7 and Fig. 8), as Figure 12 describes, when binding lens paperbound, without lens Piece shares common base.Alternatively, the multiple fragments or doubling page (39) once folded along line (40) in center are leaned against Privately stacking or glued together, to form the internal pages (41) of book, and can use biography in the case where adding hard front cover Library's method for stitching of system, spine or the folded edge of internal pages (42) are extra by fabric or the like (43) whereby Ground is reinforced.It is referred to as " hard burlap " using the most common cloth with the cardboard for covering book with library's adhesive, cardboard can also Covered by acrylic plastics.Internal pages are so completed, internal pages are then attached to envelope using traditional method for stitching Face, is either attached to hard front cover or is attached to softcover.

The section of the doubling page of bookbinding when Figure 13 illustrates Figure 12 enlarged drawing and depicts closing, shows combination Bound to multiple doubling pages (45) and by stiffener (46) to the single double spread (44) of spine.

Figure 14 refers to Figure 11 and Figure 13, but the doubling page of bookbinding when alternatively showing opening and flat placement Section.Figure 11 is informative, depict book it is flat place (47) when and open when double spread.It is closed in section The double spread of combination described by (48), all double spreads are scribed and folded along line (49), then pass through stiffener (50) combine.

On the figure of page 6, Figure 15 depicts the lens of the printing as front cover (51), and lens is drawn along line (52) Line and folding.Front cover can be laminated to hard substrate (53), and hard substrate (53) is equally scribed and folded (52) so that front cover Reinforce.According to the method for front cover to be bound to internal pages, the quantity of the line (54) in Figure 16 can be from one or many It is individual to be changed.Front cover (55) can also be bound to the same hard front cover (56) rule and folded.It is cut in addition, Figure 17 describes Sheet of single-piece, piece forms rear front cover (57), spine (58) and front cover (59), and then these pieces can be in their own position Put and independently adhere to or be layered on hard front cover (60).

The figure of page 7, Figure 18 depicts displaying and binds doubling page to the sectional view of hard front cover, wherein door leaf can be used Page.Title page (61) be by print thin lens piece, printing or non-printing the piece that is made of paper, cloth or plastics, for by front cover (63) internal pages or doubling page (62) are bound to.Title page is typically found in the back side of front cover and rear front cover.Title page can be with The size of accurate dimension or slightly smaller than hard front cover for hard front cover.Title page can be by including any soft of thin printing lens material Property material is made.Title page can adhere to or be laminated (65) to front cover and the doubling of bookbinding by multiple line (chain-dotted line) at them Be conducive to the closing of front cover during page.Softcover can be made up of single lens piece, and the lens is scribed many for folding It is secondary and allow front cover to surround completely, the connecting inner page.If softcover is more than internal pages during constructing, whole book can To be trimmed to change size.The hard front cover or softcover of this method assent are presented as being made up of the lens printed completely, There is the lens visual effect of printing on each flat surfaces including front cover and all internal pages.

The figure of page 8, Figure 19 depicts the sectional view for being illustrated in the method used during bookbinding lens, the thickness of the lens Less than 0.5mm and it can require interior cross-page.In this case, single lens piece (66) is used and double spread is made.The party Method requires to rule to single lens piece along line (67) using the metal line blade (68) of heating.Blade is given enough heat Amount has too big pressure with the slight fusing plastic lens piece when being extruded along line, otherwise can cause the knife of heating Piece completely penetrates through piece.This will make whole piece stand intact.Therefore piece along line (69) it is sufficiently thin with give lens it is flexible and Piece is folded.The CT (computed tomography) controlled by using computer engraves the marking knife that milling machine replaces heating Piece, it is possible to achieve same effect.Scribble method is uncorrelated to claim, but lens subtracts along fold line on thickness Small, so piece can be folded, this is critically important.

Figure 20 is the sectional view for the method before lens establishment double spread seen in fig. 12 with reference to before, thoroughly Eyeglass (70) can also be laminated to substrate (71), for reinforcing and being folded into double spread (72) along line.However, rule herein Construction reduce width of the lens material at line so that lens material is more flexible, it is allowed to single be folded simultaneously protect Hold excellent (73).Figure 13 and Figure 14 is similarly referred to, multiple doubling pages are combined together to create in lens book Portion's page, lens book can also further be reinforced by using stiffener, then be wrapped in front cover.
