凹印原稿的處理最關(guān)鍵的步驟就是補(bǔ)漏白,對(duì)于塑料薄膜的印刷尤其重要。印刷完成后進(jìn)行薄膜復(fù)合及切分后以小卷卷材形式交給巧克力廠。以復(fù)合膜作為承印材料,其結(jié)構(gòu)為典型PET/AL/NY/PE,外層采用聚酯薄膜(PET)進(jìn)行里印,然后再與已真空鍍鋁(AL)的尼龍薄膜(NY)和里層的聚乙烯塑料薄膜(PE)進(jìn)行三層干式復(fù)合。目錄第一章 整體方案規(guī)劃 1第二章 印前工藝設(shè)計(jì) 1 原稿處理與分色 1 圖文處理 2 拼版 2 2 制版參數(shù)確定 2 制版要求 3 印刷色序的確定 3 打樣 4第三章 印刷過程設(shè)計(jì) 4 4 外層膜材料的選擇 4 中間層材料的選擇 4 5 油墨選擇 5 表面處理 5 上機(jī)印刷 6 所用印刷機(jī)介紹 6 裝版 7 壓印滾筒調(diào)整 7 刮墨刀的安裝與調(diào)節(jié) 8 8 8 開機(jī)試印 8 張力設(shè)定 8 印刷壓力的設(shè)定 9 套準(zhǔn)調(diào)節(jié) 9 干燥裝置與冷卻裝置的設(shè)定 9 10 印刷車間溫、濕度的控制 10第四章 印后加工設(shè)計(jì) 10 干式復(fù)合工藝介紹 10 所用復(fù)合機(jī)介紹 10 復(fù)合過程 12 復(fù)合控制 12 13 切分復(fù)卷工藝設(shè)計(jì) 13參考文獻(xiàn): 1515第一章 整體方案規(guī)劃 目標(biāo)產(chǎn)品是德芙果仁巧克力43g裝塑料軟包裝。 Aluminized posite membrane。關(guān)鍵詞:巧克力軟包裝;凹版印刷;鍍鋁復(fù)合膜;干式復(fù)合;ABSTRACTThis design is based on the analysis of dove chocolate plastic flexible packaging, textbook knowledge bined with the course content and look up for any information that may be, make the product printing production process. Design process in the production process as the main line, with textbook knowledge is given priority to, bined with access to information and personal thinking, pleted the chocolate in the production of flexible packaging printing on material selection, gravure printing process, the thin film posite, segmentation process flow design, etc. The packaging structure for typical PET/AL/NY/PE posite membrane, substrates for the outer layer of the polyester film (PET), gravure printing machine adopt FR300 shaftless driving unit type for seven colors in the print. Printing the finished PET nylon with vacuum aluminum plating film (NY), polyethylene (PE) plastic film after MDL200 three layer dry posite machine posite, the FSD slitting machine segmentation rewinding for small volume after finish the whole production process. key words: flexible packaging of Chocolate。本包裝結(jié)構(gòu)為典型PET/AL/NY/PE復(fù)合膜,承印材料為外層的聚酯薄膜(PET),采用FR300無軸傳動(dòng)機(jī)組式凹版印刷機(jī)進(jìn)行七色里印。 課程設(shè)計(jì)(論文) 題 目: 印刷生產(chǎn)工藝課程設(shè)計(jì) 子 題:德芙巧克力塑料薄膜軟包裝的印刷生產(chǎn)工藝設(shè)計(jì)專 業(yè): 印刷工程 指導(dǎo)教師:
