【新型所屬之技術領域J 本創作係關於一種印刷技術的應用領域,尤指一種具 有高解析防偽印刷膜的裝置者。 【先前技術】 一般具有價值的物品都怕他人偽製仿造,諸如許多高 價商品、個人證件或金融卡片等,因其本身具有具有一定 重要的價值,因此,防偽的功能是必備的項目之一。 現有的防偽的技術有相當多種,其中有一種即是利用 印刷的技術的變化達到防偽的功效,諸如使用微細字印刷 以防止利用電腦掃描的方式偽造的方式;或是將兩種不同 畫素[解析度]的資訊結合在一起,藉由調整個別的畫素百 分比例(即灰階度),可讓人眼視覺在一定距離產生單一色 調的感覺。此種技術可將防偽資訊隱藏起來達到防偽的效 果,同時又不影響整個版面的美觀,並可藉由複印知偽造 與否,由於影印機對高畫素無法有效取樣,而使複印品顯 現出隱藏的圖文資訊,即可知偽造與否。 然而,上述的防偽技術已經能被有心份子輕易破解, 因此,發展防偽功效更強的技術手段實在有其必要性,以 確保商品、個人證件、重要文件或金融卡片等防偽功效。 【新型内容】 本創作之主要目的在於提供一種具有高解析防偽印刷 膜的裝置,其係藉由高解析度與光柵光學折射加密的製作 以提高印刷膜的防偽效果。 ’、、’達上述目的’本創作係包含有一防偽圖文資訊與一 防偽圖文資訊係隱藏於本體的表面上並包含有複 ㈣Μ圖文資訊經—具有複數平行的柱狀凸透 鏡的先栅光學折射後位置的晝素,所述畫素並具有一解析 度,所述解析度係界於每平方公分i 8 〇至2 8 〇畫素間 〇 藉此,本創作之具體達成的功效在於: 防偽圖X資訊的構成畫素係設於經光桃的柱狀凸透鏡 聚焦加密處理後,所產生縮小與偏移的位置,因此,當未 使用光栅解雄、時,防偽圖文資訊係可隱藏於本體表面的背 眾圖文:貝中’此時,人眼是無法直接看出防偽圖文資訊 ’而達到防偽的功效。 同時,當仿製者如未能取得加解密光柵時,即無法成 功看見取得或複製隱藏的防偽圖文資訊,使仿製無法成功 ,以達進一步加強防偽的功效。 【實施方式】 一種具有高解析防偽印刷膜的裝置,其係包含有一防 偽圖文資訊與一本體,藉由一光柵使用光學折射加密的方 式將防偽圖文資訊隱藏於本體的表面上,請參照第一圖所 示,為方便說明起見,以下以將一字母A ( 1 〇 )[即防偽 圖文資訊]隱藏於一瓶蓋(2 0 )[即本體]上作為說明, 如此,當使用該瓶蓋(2 0 )蓋合如酒瓶時,可加強該瓶 酒的防偽功能。 一般印刷圖文資訊於一物體上時,皆是以複數印刷線 M247396 條或網點構成該圖文資訊,而印刷線條或網點統稱為畫素 ’每單位面積内畫素的數量密集程度稱為解析度〔 Resolution〕,所以,舉例來說,字母a (丄〇 )係可由 複數個畫素構成,一般若直接將字母A ( i 〇 )直接印刷 於瓶蓋(20)上,則字母A(l〇)為可見,因此,本 創作使用一光柵(2 1 )先行將字母A ( i 〇 )作加密處 理,以形成字母A ( 1 〇 )構成畫素的位置。 請參照第一圖與第二圖所示,該光柵(2 i )係具有 複數微細平行排列的柱狀凸透鏡(211),如第二圖所 不,平行虛線係表示人眼的視線,當視線經柱 2⑴折射後,會被聚焦於一位置,因此,使丄兄( 21)對字母A(l〇)進行加密時,可將字母Α(ι〇 )置於該光柵(2 1 )對應人眼視線側的位置,藉由調整 光柵(2 1 )之柱狀凸透鏡(2 i i )的景深崎焦距位 置’得到字母A(1Q)於光柵(21)另側相對於每一 柱狀凸透鏡(211)的聚焦位置’此位置即為字母A( 1 0 )構成畫素的位置。 請參照第一圖、第三圖與第四圖所示,其中,若取瓶 蓋一(2 0 )表面一微小區域B的放大圖觀之,平行實線係 表示瓶蓋(20)表面上,背景圖文資訊的構成畫素,平 行虛線係表示字母A ( 1 ◦)經光栅(2 1 ) h密處理後 ’其構成畫素的位置’由於字母A(1〇)經柱狀凸透鏡 (2 1 1 )光予折射聚焦時,其構成畫素會較初始直接構 成字母A(l〇)的畫素產生縮小與偏移現象,因此,當 M247396 未使用光栅(2 1)覆蓋於瓶蓋(20)表面上產生解密 效果時,人眼是無法直接看出字母A(1〇)的存在,達 到資訊隱藏防偽的功效,同時,該字母A ( 1 〇 )的解析 度以每平方公分1 8 0至2 8 〇畫素為具有最佳的隱藏效 果。 當使用光柵(2 1)覆蓋於瓶蓋(20)表面上時, 原本構成字母A( 1 〇)縮小與偏移的畫素,經由柱狀凸 透鏡(2 1 1 )光學折射成為人眼可見的平行光線,即可 達到將字母A ( 1 〇 )顯現的目的。 因此,本創作之本體,可如前述瓶蓋(2 〇 ) 、IC智 慧卡、重要文件或貨幣等具有保護價值的物品,而該防偽 圖文資讯可為複雜或任意的圖形或文字,當仿製者如未能 取得光柵(21)時,即無法成功看見、取得或複製隱藏 的防偽圖文資訊,使仿製無法成功,以達防偽的功效。 上述所揭露的本創作之技術手段,係僅用以說明本創 作之較佳實施狀態,但不代表本創作之實施態樣限於上述 所揭露的較佳實施例,對熟悉此項技術的人士,依據本創 作做如外型或大小上但實質上卻與本創作所揭露的技術手 段相同的變更,亦不應被排除於本創作所欲請求保護的申 請專利範圍之外。 M247396 【圖式簡單說明】 (一) 圖式部分 第一圖係本創作較佳實施例之使用狀態立體圖。(代 表圖) 第二圖係本創作較佳實施例之使用一光柵可使一防偽 圖文資訊作加、解密的示意圖。 第三圖係本創作較佳實施例之第一圖中的瓶蓋,在未 使用光柵解密時防偽圖文資訊被隱藏的立體圖。 第四圖係本創作較佳實施例之於第三圖中標示B區域 的放大圖,係用以說明背景圖文資訊與防偽圖文資訊間構 成畫素的關係。 (2 0 )瓶蓋 (2 1 1 )柱狀凸透鏡 (二) 元件代表符號 (1 ◦)字母A (21)光栅[Technical field to which the new type belongs J This creation relates to the application field of a printing technology, especially a device with a high-resolution anti-counterfeit printing film. [Prior technology] Generally, valuable items are afraid of being counterfeited by others, such as many high-priced goods, personal certificates, or financial cards. Since they have a certain important value, the anti-counterfeiting function is one of the necessary items. There are quite a few existing anti-counterfeiting technologies, one of which is to use the changes in printing technology to achieve anti-counterfeiting effects, such as the use of micro-character printing to prevent counterfeiting by computer scanning; or two different pixels [ Resolution] information is combined together, and by adjusting individual pixel percentage examples (ie, gray levels), it can make people's visual sense produce a single color tone at a certain distance. This technology can hide the anti-counterfeiting information to achieve the effect of anti-counterfeiting, without affecting the aesthetics of the entire layout. It can also know whether it is counterfeit or not by copying. Since the photocopier cannot effectively sample high pixels, the copy appears. Hidden graphic information, you can know whether it is forged or not. However, the above-mentioned anti-counterfeiting technology can be easily cracked by conscientious elements. Therefore, it is necessary to develop technical means with stronger anti-counterfeiting effects to ensure the anti-counterfeiting effects of commodities, personal certificates, important documents or financial cards. [New content] The main purpose of this creation is to provide a device with a high-resolution anti-counterfeiting printed film, which is made by high-resolution and grating optical refraction encryption to improve the anti-counterfeiting effect of the printed film. ',,' Achieving the above purpose 'This creative system contains an anti-counterfeit graphic information system and an anti-counterfeit graphic information system hidden on the surface of the body and contains a complex text and image information script—a sill with a plurality of parallel cylindrical convex lenses The day element at the optically refracted position, the pixel has a resolution, the resolution is between i 8 0 and 2 8 0 pixels per square centimeter. By this, the specific effect of this creation is that : The constituent pixels of the anti-counterfeit image X information are set at the reduced and shifted position after the focus encryption processing of the lenticular convex lens of the photo peach. Therefore, when the raster is not used to detangle the image, the anti-counterfeit image information can be Hidden figures and texts hidden on the surface of the body: "At this time, the human eye cannot directly see the anti-counterfeit graphic information" to achieve the effect of anti-counterfeiting. At the same time, if the copycat fails to obtain the encryption / decryption raster, it cannot successfully see that the hidden anti-counterfeiting graphic information is obtained or copied, making the imitation unsuccessful, so as to further strengthen the anti-counterfeiting effect. [Embodiment] A device with a high-resolution anti-counterfeiting printing film, which includes an anti-counterfeiting graphic information and a body, and the optical security information is hidden on the surface of the main body by a grating using optical refraction encryption. Please refer to As shown in the first figure, for the convenience of explanation, the following is to hide a letter A (1 0) [that is, anti-counterfeit graphic information] on a bottle cap (20) [that is the body] as an illustration. When the bottle cap (20) is closed like a wine bottle, the anti-counterfeiting function of the bottle of wine can be strengthened. Generally, when printing graphic information on an object, the graphic information is composed of a plurality of printed lines M247396 or dots, and the printed lines or dots are collectively referred to as pixels. The density of pixels per unit area is called resolution. Resolution [Resolution], for example, the letter a (丄 〇) can be composed of multiple pixels. Generally, if the letter A (i 〇) is directly printed on the bottle cap (20), the letter A (l 〇) is visible, therefore, this creation uses a raster (2 1) to encrypt the letter A (i 〇) first to form the position where the letter A (1 〇) constitutes a pixel. Please refer to the first figure and the second figure. The grating (2 i) has a plurality of cylindrical convex lenses (211) arranged in parallel, as shown in the second figure. The parallel dashed line indicates the line of sight of the human eye. After being refracted by the column 2⑴, it will be focused on a position. Therefore, when the brother A (21) encrypts the letter A (l0), the letter A (ι〇) can be placed on the corresponding person of the grating (2 1). The position of the line of sight is adjusted by adjusting the depth-of-field position of the lenticular lens (2 ii) of the grating (2 1) to obtain the letter A (1Q) on the other side of the grating (21) relative to each lenticular lens (211 ) Focus position ') This position is the position where the letter A (1 0) constitutes a pixel. Please refer to the first figure, the third figure and the fourth figure. Among them, if an enlarged view of a small area B on the surface of the bottle cap (2 0) is taken, a parallel solid line indicates the surface of the bottle cap (20). The background pixels constitute the picture element. The parallel dashed lines indicate that the letter A (1 ◦) is densely processed by the grating (2 1) and its position of the picture element is formed because the letter A (1〇) passes through a cylindrical convex lens ( 2 1 1) When light is pre-refracted and focused, its constituent pixels will be reduced and shifted from the original pixels that directly constitute the letter A (l0). Therefore, when M247396 is not covered with a grating (2 1), the bottle cap is covered. (20) When the decryption effect occurs on the surface, the human eye cannot directly see the existence of the letter A (1〇), which achieves the effect of information hiding and anti-counterfeiting. At the same time, the resolution of the letter A (10) is 1 per square centimeter. 80 to 280 pixels have the best hiding effect. When the grating (2 1) is used to cover the surface of the bottle cap (20), the pixels that originally formed the letter A (1 0) are reduced and shifted, and become optically visible to the human eye through a cylindrical convex lens (2 1 1). Parallel rays of light can achieve the purpose of displaying the letter A (1 0). Therefore, the body of this creation can be items with protective value such as the aforementioned bottle cap (20), IC smart card, important documents or currency, and the anti-counterfeit graphic information can be complex or arbitrary graphics or text. If the imitator fails to obtain the grating (21), he cannot successfully see, obtain or copy the hidden anti-counterfeit graphic information, making the imitation unsuccessful to achieve the effect of anti-counterfeiting. The above-disclosed technical means of this creation are only used to explain the preferred implementation state of this creation, but it does not mean that the implementation mode of this creation is limited to the above-disclosed preferred embodiments. For those who are familiar with this technology, Changes in appearance or size based on this creation that are substantially the same as the technical means disclosed in this creation should not be excluded from the scope of the patent application for which this creation is intended to be protected.
