印刷後再次加工的方法Method of reprocessing after printing

本發明為有關一種印刷方法，尤指一種印刷後再次加工的方法。The present invention relates to a printing method, and more particularly to a method of reworking after printing.

印刷術為中國古代四大發明之一，其係為將影像或文字原稿迅速大量複製的一種技術，更重要的是，印刷術是人類近代文明的先導，因為印刷術發明之前，知識的傳播主要靠人力進行抄寫，不僅費時、費力，又容易產生錯誤，而透過印刷大量的複製相關書件，才可以將知識廣泛的傳播。Printing is one of the four great inventions in ancient China. It is a technique for rapidly copying images or manuscripts in large quantities. More importantly, printing is the forerunner of modern human civilization, because the dissemination of knowledge was mainly before the invention of printing. Copying by manpower is not only time-consuming, laborious, but also prone to errors. By printing a large number of copies of related books, knowledge can be widely disseminated.

目前印刷可以分類為平版印刷、凸版印刷、凹版印刷及網版印刷等，而印刷的第一步，就是製版，而後才可進行印刷，而製版時需要進行曬版程序，才可於版上形成圖案，如中國專利第CN 202948248號之「網版貼菲林治具」，其包括一透光底座、一定位銷和一透明平臺，於該透明平臺上繪出定位線，再利用該定位銷將一網版定位在該透光底座上，而後貼附上底片，進行曝光蝕刻等製程，即可完成。At present, printing can be classified into lithographic printing, letterpress printing, gravure printing and screen printing, etc., and the first step of printing is to make a plate, and then printing can be carried out, and the plate-making process is required for plate-making to form on the plate. a pattern, such as the "Web version of the film fixture" of the Chinese Patent No. CN 202948248, which comprises a transparent base, a positioning pin and a transparent platform, on which the positioning line is drawn, and then the positioning pin is used A screen is positioned on the light-transmissive base, and then the backsheet is attached, and a process such as exposure etching is performed.

此種方式雖然會先繪出定位線，但仍需要利用人工來進行對位排版，而容易造成對位上的誤差，降低印刷的精準度，且需要較長的對位時間，除此之外，亦必須利用底片曝光的方式方能進行製版，耗費許多底片材料的問題，而增加印刷成本。因此，如何提高精準度、減少對位時間以及降低成本，實為一大課題。Although this method will first draw the positioning line, it still needs to use manual to perform the alignment typesetting, which is easy to cause the error in the alignment, reduce the printing precision, and requires a long alignment time, in addition to this. It is also necessary to use a film exposure method to perform plate making, which consumes a lot of film material problems and increases printing costs. Therefore, how to improve the accuracy, reduce the alignment time and reduce the cost is a big issue.

本發明的主要目的，在於解決印刷的精準度低、對位時間長以及高成本的問題。The main object of the present invention is to solve the problems of low printing accuracy, long alignment time, and high cost.

為達上述目的，本發明提供一種印刷後再次加工的方法，包含有以下步驟： S1：形成一基礎圖樣於一待加工品上； S2：透過一影像擷取單元取得該基礎圖樣的電子圖像； S3：透過與該影像擷取單元電性連接之一電腦，校正一加工圖案之絕對位置資訊，以對應於該電子圖像，並藉此形成一加工版，該加工版具有一對應於該電子圖像的再加工區；以及 S4：將該待加工品輸入至一與該電腦電性連接之加工處理單元中，以對應該加工版之該再加工區與該待加工品的位置並進行加工。In order to achieve the above object, the present invention provides a method for re-processing after printing, comprising the following steps: S1: forming a basic pattern on a workpiece to be processed; S2: obtaining an electronic image of the basic pattern through an image capturing unit S3: correcting the absolute position information of a processing pattern by using a computer electrically connected to the image capturing unit to correspond to the electronic image, and thereby forming a processing plate, the processing plate having a corresponding one a reworking area of the electronic image; and S4: inputting the to-be-processed product into a processing unit electrically connected to the computer to correspond to the position of the reworked area and the to-be-processed product of the processed plate machining.

綜上所述，本發明透過電腦校正取代傳統利用人工排版的方式，可以增加印刷的精準度以及減少時間的浪費，並且更進一步的避免使用底片，而可有效降低製作成本。In summary, the present invention replaces the traditional use of manual typesetting by computer correction, which can increase the precision of printing and reduce the waste of time, and further avoid the use of negative film, and can effectively reduce the production cost.

步驟S3B：校正過後，形成對應的該加工版40，如「圖3C」所示，依序形成一光阻32與一圖形化阻擋層33於該加工版40上，該圖形化阻擋層33可以利用噴塗的方式形成，更進一步的說明，可以利用噴墨技術(ink jet)的方式達到精細噴塗的效果，如此一來，所形成的該圖形化阻擋層33會較為精細。而於本實施例中，該光阻32的材質可以為酚醛樹脂、環氧樹脂、聚異戊二烯橡膠或其組合等。Step S3B: After the correction, the corresponding processing plate 40 is formed. As shown in FIG. 3C, a photoresist 32 and a patterned barrier layer 33 are sequentially formed on the processing plate 40. The patterned blocking layer 33 can be It is formed by spraying, and further, the effect of fine spraying can be achieved by means of an ink jet, and thus the patterned barrier layer 33 is formed to be finer. In this embodiment, the material of the photoresist 32 may be phenolic resin, epoxy resin, polyisoprene rubber or a combination thereof.

步驟S3C：如「圖3D」所示，對該光阻32進行曝光，於本實施例中，係使用正光阻，使得被照射的光阻軟化，但亦可以使用負光阻，不以此為限。再對該光阻32進行蝕刻，以將被軟化的該光阻32以及該圖形化阻擋層33去除，而形成該圖形化遮罩30，且該圖形化遮罩30具有一對應於該電子圖像的再加工區41。Step S3C: exposing the photoresist 32 as shown in FIG. 3D. In the embodiment, a positive photoresist is used to soften the irradiated photoresist, but a negative photoresist may also be used. limit. The photoresist 32 is etched to remove the softened photoresist 32 and the patterned barrier layer 33 to form the patterned mask 30, and the patterned mask 30 has a corresponding electronic image. The rework area 41 of the image.

步驟S4：最後，如「圖3E」所示，將該待加工品10輸入至一與該電腦80電性連接之加工處理單元90中，該加工處理單元90會對應該加工版40與該待加工品10的位置，以對該待加工品10進行加工，於本實施例之網版印刷中，係包含有以下步驟：Step S4: Finally, as shown in FIG. 3E, the product to be processed 10 is input into a processing unit 90 electrically connected to the computer 80, and the processing unit 90 corresponds to the processing plate 40 and the waiting for processing. The position of the processed product 10 is processed to the workpiece 10 to be processed. In the screen printing of the embodiment, the following steps are included:

S4A：將該待加工品10輸入該加工處理單元90中，該加工處理單元90將該加工版40之該再加工區41與該待加工品10進行加工位置的對應定位。S4A: The workpiece 10 to be processed is input into the processing unit 90, and the processing unit 90 positions the rework area 41 of the processing plate 40 and the workpiece 10 in a corresponding position.

S4B：塗佈一塗料50於該圖形化遮罩30上，該塗料50透過該圖形化遮罩30與該加工版40而形成該加工圖案20於該待加工品10上，而後，如「3F」所示，移除該加工版40，該加工圖案20會對應於該加工版40而具有一定之厚度，若從正面進行觀看，則與「圖3A」相同，但利用手指觸摸則可感覺出厚度的差異，圖中之厚度會繪製的較厚，以利於示意說明。S4B: coating a coating 50 on the patterned mask 30, the coating 50 passes through the patterned mask 30 and the processing plate 40 to form the processing pattern 20 on the workpiece 10, and then, for example, "3F As shown, the processing plate 40 is removed, and the processing pattern 20 has a certain thickness corresponding to the processing plate 40. If viewed from the front, it is the same as "Fig. 3A", but it can be felt by touching with a finger. The difference in thickness, the thickness in the figure will be drawn thicker to facilitate the illustration.

需特別說明的是，該加工版40更可以為儲存於該電腦80中的數位版，當取得該基礎圖樣60的電子圖像，並透過該電腦80校正後，即會於該電腦80中形成數位版，當該待加工品10輸入至該加工處理單元90後，會直接對應該數位版而進行噴塗，就不需要實際製作出該加工版40，而可降低成本，並提高製程效率。It should be noted that the processing plate 40 can be a digital version stored in the computer 80. When the electronic image of the basic pattern 60 is obtained and corrected by the computer 80, it is formed in the computer 80. The digital version, when the workpiece 10 is input to the processing unit 90, directly sprays the digital plate, so that the processing plate 40 does not need to be actually produced, and the cost can be reduced and the process efficiency can be improved.
