包裝袋印刷工藝您了解嗎？

Do you know the packaging bag printing process

包裝袋是在常見(jiàn)不過(guò)得了，在我們生活中也是離不開(kāi)它的使用。對(duì)于生產(chǎn)商來(lái)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(lái)就由小編簡(jiǎn)單為您講一下有關(guān)印刷工藝是怎樣的吧？

Packaging bags are common, but we can not live without their use. For manufacturers, what are the processes of color printing on plastic bags? Next, let's talk about the printing process?

一、凹版印刷

1、 Intaglio 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(zhì)量高、墨層厚實(shí)、色彩鮮艷、圖案清晰明快、畫(huà)面層次豐富、反差適度、形象逼真、立體感強(qiáng)等優(yōu)點(diǎn)。凹版印刷要求各色圖案套準(zhǔn)誤差不大于0.3mm，產(chǎn)品同色密度偏差和同批同色偏差等指標(biāo)符合GB7707-87要求。凹版印刷的印版耐印力強(qiáng)，適于長(zhǎng)版活件

The printing of plastic film is mainly based on the intaglio printing process. The plastic film printed by intaglio has the advantages of high printing quality, thick ink layer, bright colors, clear and bright patterns, rich picture levels, moderate contrast, vivid image, strong three-dimensional sense, etc. For intaglio printing, the registration error of all color patterns shall not be greater than 0.3mm, and the product density deviation and the deviation of the same color of the same batch shall meet the requirements of GB7707-87. The printing plate of intaglio printing has strong printing resistance and is suitable for long version 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(shè)備簡(jiǎn)單，成本低，版材質(zhì)量輕，印刷時(shí)壓力小，版材及機(jī)械損耗小，印刷時(shí)噪聲小、速度快。柔性版換版時(shí)間短、工效高,柔性版柔軟、有彈性、傳墨性能好,印刷材料適應(yīng)面廣，對(duì)于印刷小批量的產(chǎn)品成本比凹版印刷低。但柔性版印刷對(duì)油墨和版材的要求較高，因此印刷質(zhì)量比凹版工藝稍遜。

Flexographic printing mainly uses flexographic letterpress and fast drying letterpress inks. It features simple equipment, low cost, light plate quality, low pressure during printing, small plate and mechanical loss, low noise and fast printing speed. The flexographic plate has a short change time and high work efficiency. The flexographic plate is soft, elastic, and has good ink transmission performance. The printing materials are widely used. The cost of printing small batches of products is lower than that of intaglio printing. However, flexographic printing has higher requirements for inks and plates, so the printing quality is slightly inferior to that of intaglio printing.
