            通明油墨的挑選和運用
          Selection and application of transparent ink
          通明油墨的挑選運用要依據不同的承印物特色客戶的要求等進行,歸納起來,首要從以下3個方面來考慮,合理挑選通明油墨。
          The selection and application of clear ink should be based on the requirements of customers with different characteristics of the printed material. To sum up, the following three aspects should be considered first, and the clear ink should be selected reasonably.
          1.依據承印資料選用與之習慣的油墨:如印刷表印鍍鋁膜時有必要挑選表印通明油墨:印刷BOPP薄膜又要復合鍍鋁時則應選用里印通明(復合)油墨。所以,能夠這樣說承印資料的種類決議了運用的油墨類型即使是同一種類的薄膜資料,也往往因種類和等級的不同而有所差異。別的留意,選用通明油墨印刷時一般在該色案下面不必白色墊底,因為白色起消光作用會大大下降其運用作用和價值。相對來講,通明油墨印刷的色案處比有白色油墨墊底的地方薄O.Olmm。
          1. Choose the ink that is used to it according to the printing material: If it is necessary to select the clear ink when printing aluminized film, it is necessary to use the clear ink when printing BOPP film and composite aluminizing ink when printing BOPP film. Therefore, it can be said that the type of printed material determines the use of ink types, even if the same kind of film materials, also often varies according to the type and grade. Otherwise, when using clear ink to print, it is not necessary to use white as the bottom of the color case, because white will greatly reduce its use and value. Relatively speaking, the case of brightly printed ink is O.Olmm thinner than that with white ink.
          2.依據客戶供給的樣品挑選習慣的通明油墨:通明油墨的挑選包含色相和色澤.若要分配專色通明油墨時,有必要咨詢出產供貨商因為通明油墨專色的分配不同于一般專色油墨,其難度顯著高于不通明油墨專色分配。

          2. According to the customer's sample selection habits bright ink: clear ink selection contains color and color. To distribute spot color bright ink, it is necessary to consult the manufacturer because the distribution of spot color bright ink is different from the general spot color ink, the difficulty is significantly higher than that of opaque ink spot color distribution.

          3.依據包裝的實際情況和用處挑選相應的通明油墨:如包裝印刷品耐高溫、耐曬、耐透滲等參數,這些都有必要列入挑選的考慮領域。此外,通明油墨印刷要想取得高亮度和艷麗的色彩離不開鍍鋁膜或鋁箔紙、鋁箔等資料因為通明油墨的通明性極高與鍍鋁膜復合或直接印刷到上述資料上會發作改變以透出金屬的光澤與色彩.使黃更黃、綠更綠、紅更紅作用更佳。
          3. According to the actual situation and use of the packaging to select the appropriate clear ink: such as packaging printing high temperature resistance, sunlight resistance, permeability and other parameters, these are necessary to be included in the selection of areas of consideration. In addition, bright ink printing can not get high brightness and gorgeous color without aluminum film or aluminum foil paper, aluminum foil and other information because of the high brightness of bright ink and aluminum film composite or directly printed to the above information will be changed to penetrate the luster and color of the metal, so that yellow, green, red and green role better. .
          通明油墨印刷中常見毛病的掃除
          Elimination of common faults in ink printing
          通明油墨在軟包裝印刷運用過程中,多用鍍鋁膜或鋁箔墊底以進步印刷和視覺作用。但在實際運用過程中常常發作一些質量現象比如通明油墨印刷後有麻點、鋪墨不平等現象這樣就大大下降了其預期作用,因而要了解通明油墨的性質及印刷特色,分析掃除。
          In the process of flexible packaging printing, transparent ink usually uses aluminum film or aluminum foil to pad the bottom to improve printing and visual effect. However, in the actual application process, some quality phenomena often occur, such as numbness and inking inequality after the printing of clear ink, which greatly reduces its expected effect. Therefore, it is necessary to understand the nature of clear ink and printing characteristics, analysis and cleaning.
          1.通明油墨印刷時發作“麻點”現象
          1. ink printing occurs when printing.
          首要原因和處理辦法這種毛病表現為印刷後的產品墊上鍍鋁膜後,其亮光作用就出來了,但仔細調查會發現其外表有針孔狀,好像是未印刷上去。發作這個毛病的首要原因是:
          The primary cause and treatment of this problem is that after the printed product is coated with aluminium film, its brightening effect comes out, but careful investigation will find that the appearance of the pinhole, as if not printed. The main reason for this attack is:
          ヾ壓印膠輥外表不可細膩,或有塵埃等異物,形成此處油墨不可厚。應查看壓印膠輥是否粘有髒物,並將其外表擦洗潔淨;查看膠輥質量.替換合格的膠輥。
          (1) the appearance of imprint cots can not be delicate or dust and other foreign matter. Ink can not be thickened here. Check whether the embossing cots are sticky with dirt and scrub them clean. Check the quality of the cots. Replace the qualified cots.
          ゝ薄膜中所含的增塑劑、光滑劑等浮到外表上阻礙了油墨的正常搬運和光滑。印刷前要將塑料薄膜預熱等印前處理,實施薄膜加溫印刷若還不可則應替換適宜的塑料薄膜。
          (2) The plasticizer and smoother contained in the film float to the surface and hinder the normal transportation and smoothness of the ink. The plastic film should be preheated before printing, and the suitable plastic film should be replaced if the film heating printing can not be carried out.
          ゞ油墨鑽度太高、枯燥過快或鑽著劑缺少形成油墨搬運、濕潤習慣性不良。應適當下降油墨鑽度而且用緩千溶劑。
          3. Ink drills are too high, drunks too fast or lack of drilling agents to form ink handling and poor wetting habits. Ink drills should be appropriately lowered and slow solvent should be used.
          々印刷壓力太小。可適當加大印刷壓力並注憊操控好印刷壓力(一般在4kg左右)。
          (4) printing pressure is too small. Printing pressure can be increased appropriately, and printing pressure can be controlled (usually around 4kg).
          ぁ印版或壓印膠輥的問題(表現為麻點比較有規則)應仔細查看印版及壓印膠輥是否有缺點若有則應從頭制版或替換好的膠輥。
          _printing plate or offset roll problems (for pitting is more regular) should be carefully checked whether the plate and offset roll has any shortcomings, if any, should be made from scratch or replace the good roll.
          2.印刷通明油墨後發作粘連現象
          2. adhesion after printing.
          首要原因和處理辦法:在高溫、高濕的梅雨季節塑料膜通過凹版印刷後收卷放皿期間易發作粘連現象,通明油墨被成塊粘下來,在油墨處甚至不能與基層塑料膜分開,致使形成許多廢品。印品發作粘連大多是由油墨發鑽、環境濕度太高、壓力太大等形成的。
          Primary reason and treatment: plastic film in high temperature, high humidity Meiyu season through gravure printing during the roll-up and dish-release easy to occur adhesion, clear ink is sticky in pieces, in the ink can not even be separated from the basic plastic film, resulting in a lot of waste products. Most of the printed products are caused by ink drills, environmental humidity and pressure.
          3.印刷通明油墨鍍鋁復合後光澤度不高
          3. printing bright ink, aluminum plating compound after gloss is not high.
          首要原因和處理辦法:發作這種現象的首要原因是:ヾ油墨自身的通明性差應替換通明性好的油墨。
          The first reason and treatment: the first reason for this phenomenon is: 1. Ink itself poor brightness should replace good brightness of the ink.
          ゝ印刷時溶劑蒸騰太快鑽度太低,應依據孺要選用適宜的慢干溶劑,查看並進步油墨鑽度。ゞ鍍鋁層均性不良,形成反光澤差要替換鍍鋁膜並確保其外表均勻、無針孔。々刮墨刀視點太大印版網穴淺要調整操控好刮墨刀視點,一般夾角操控在35度左右為宜。
          (2) When printing, solvent transpiration is too fast and the drilling degree is too low, the suitable slow-drying solvent should be selected to check and improve the ink drilling degree. (3) Bad homogeneity of the aluminized layer, forming poor reflective luster to replace the aluminized film and ensure its appearance uniform, no pinholes. (4) The view of the scraper is too big and the screen hole is too shallow. It is necessary to adjust and control the view of the scraper well. Generally, the angle of the scraper should be controlled at about 35 degrees.
          4.通明油墨發作結塊現象
          4. lump phenomenon
          首要原因和處理辦法:此現象一般發作在氣溫較低的情況下。此種情況下,應將油墨放里在35℃室溫下熱化。為避免意外,還有必要由專人看守。
          First and foremost reason and treatment: this phenomenon usually occurs when the temperature is low. In this case, the ink should be heated at room temperature of 35 degrees. In order to avoid accidents, it is also necessary to be watched by someone.
          總歸溶劑配比失調、鑽度操控不妥或工藝操作失誤等都極或許導致許多毛病現象所以每一個環節都不能大意。因而在運用通明油墨印刷時,要想取得抱負的作用各個環節有必要嚴格把關,而且要依據印刷的實際情況挑選適宜的油墨。
          The total solvent mismatch, improper drilling control or process operation errors are likely to cause many problems, so each link can not be neglected. Therefore, in the use of clear ink printing, in order to achieve the desired role of each link is necessary to strictly check, and according to the actual situation of printing to select the appropriate ink.
