包裝袋是在常見不過得了,在我們生活中也是離不開它的使用。對于生產商來講,塑料包裝袋上的彩印印刷有著怎樣的工藝有哪幾種呢?接下來就由小編簡單為您講一下有關印刷工藝是怎樣的吧?

Packaging bag is common in our life, but we can't live without its use. For manufacturers, what are the processes of color printing on plastic packaging bags? Next, let's talk briefly about the printing process for you?

包裝袋印刷工藝介紹

Introduction to packaging bag printing process

一、凹版印刷

1、 Gravure printing

塑料薄膜的印刷以凹版印刷工藝為主,用凹版印刷的塑料薄膜具有印刷質量高、墨層厚實、色彩鮮艷、圖案清晰明快、畫面層次豐富、反差適度、形象逼真、立體感強等優點。凹版印刷要求各色圖案套準誤差不大于0.3mm,產品同色密度偏差和同批同色偏差等指標符合GB7707-87要求。凹版印刷的印版耐印力強,適于長版活件

The printing of plastic film is mainly based on the gravure printing process. The plastic film printed with gravure has the advantages of high printing quality, thick ink layer, bright color, clear and lively pattern, rich picture level, moderate contrast, realistic image and strong three-dimensional sense. Gravure printing requires that the registration error of various color patterns shall not be greater than 0.3mm, and the indicators such as the same color density deviation of products and the same color deviation of the same batch shall meet the requirements of gb7707-87. Gravure printing plate has strong printing resistance and is suitable for long plate live parts

二、柔性版印刷

2、 Flexographic printing

柔性版印刷主要利用柔性凸版和快干凸版油墨。其設備簡單,成本低,版材質量輕,印刷時壓力小,版材及機械損耗小,印刷時噪聲小、速度快。柔性版換版時間短、工效高, 柔性版柔軟、有彈性、傳墨性能好, 印刷材料適應面廣,對于印刷小批量的產品成本比凹版印刷低。但柔性版印刷對油墨和版材的要求較高,因此印刷質量比凹版工藝稍遜。

Flexographic printing mainly uses flexible relief printing ink and fast drying relief printing ink. The utility model has the advantages of simple equipment, low cost, light plate material quality, low pressure during printing, low plate material and mechanical loss, low noise and fast speed during printing. Flexographic plate has the advantages of short plate changing time, high work efficiency, soft, elastic flexographic plate, good ink transfer performance, wide adaptability of printing materials, and the cost of printing small batch products is lower than that of gravure printing. However, flexographic printing has higher requirements for ink and plate materials, so the printing quality is slightly inferior to gravure technology.

三、絲網印刷

3、 Screen printing

印刷時通過刮板的擠壓,使油墨通過圖文部分的網孔轉移到承印物上,形成與原稿一樣的圖文。

During printing, through the extrusion of the scraper, the ink is transferred to the substrate through the mesh of the picture and text part to form the same picture and text as the original.


絲網印刷的產品墨層豐富、色澤鮮艷、色彩飽滿、遮蓋力強, 油墨品種選擇范圍廣、適應性強, 印刷時壓力小、便于操作, 制版工藝簡單易行、設備投資少, 因此成本低廉、經濟效益好、承印材料品種廣泛。

Screen printing products have rich ink layers, bright colors, full colors, strong covering power, wide selection range of ink varieties, strong adaptability, low pressure during printing, easy operation, simple plate making process and less equipment investment. Therefore, they have low cost, good economic benefits and a wide variety of printing materials.
