这些印刷知识您了解吗?

胶印

Offset

绝大多数的书刊画册和包装彩盒都是胶印产品。胶印是平版印刷的一种,很简单的讲胶印就是借助于胶皮(橡皮布)将印版上的图文传递到承印物上的印刷方式,即有三个滚筒(印版、橡皮布、压印)的平版印刷方式,在我国的南方把这种印刷方式称为柯式印刷。

The vast majority of books, catalogs and packaging color boxes are offset products. Offset lithography is a very simple, means of speaking that is offset rubber (Pib) will plate transfer to the substrate of printing, namely three roller (printing, lithographic printing and embossing of Pib), in the south of our country to the printing mode called Ke printing.

凹印

Gravure printing

塑料袋产品一般都是凹版印刷。凹版印刷墨色饱满有立体感,图文具有凸感,且层次丰富,线条清晰,质量高印版寿命长,适合大批大量印刷。凹印可印刷极薄的材料,如塑料薄膜。

Plastic bag products are generally gravure printing. Gravure printing full color stereoscopic graphics, has the sense of convex, and rich layers, clear lines, high quality printing plate, long service life, suitable for mass printing. Gravure printing of very thin materials, such as plastic films.

凹版印刷主要缺点有:印前制版技术复杂、周期长,制版成本高;由于采用挥发型溶剂,车间内有害气体含量较高,对工人健康损害较大;凹版印刷从业人员要求的待遇相对较高。

The main disadvantages are: gravure printing prepress technology complex, long cycle and high cost because of the plate; volatile solvent, high content of harmful gas workshop, serious damage to the health of workers; gravure printing practitioners required treatment is relatively high.

凹印制版复杂价格高,油墨污染环境。这两方面的问题影响了凹印的发展。特别是大批大量印件的减少,短版同时要求低价的印件大量增加,使凹印不断丢失市场。

Gravure printing complex, high prices, ink pollution environment. These two problems affect the development of gravure printing. In particular, a large number of printed matter reduction, short version requires a large number of low-priced printing pieces, gravure printing constantly lost market.

柔印

flexography

常见的物流包装瓦楞纸纸箱都是柔印产品。柔印是凸版印刷进化而来,柔印是一种直接印刷方式,由于使用具有弹性、凸起的图像印版而称为柔版印刷。柔版的印版粘固在印版滚筒上,印版由一根雕刻的金属网纹辊供墨。柔性版直接印刷具有如下特点:(1)幅面大。

The most common logistics packaging corrugated cardboard boxes are flexo printing products. Flexo printing is the evolution of letterpress printing, flexo printing is a direct printing method, because of the use of elastic, convex image plate known as flexo printing. The flexographic plate is glued to the plate cylinder, and the plate is supplied by a carved metal anilox roller. Flexo direct printing has the following characteristics: (1) large format.

宽幅的柔性版印刷机大幅宽可达到2.5m~2.8m。(2)价格低。柔性版耐印力很高,可重复使用;油墨价格也较低。(3)可以联动生产,如印刷、开槽、压痕、订(粘)箱、打捆等一机即可完成。(4)纸箱强度降低比较少。

The maximum width of the wide flexo press reaches 2.5m~2.8m. (2) low price. Flexo printing is very high, can be reused; ink prices are also low. (3) linkage production, such as printing, slotting, indentation, ordering (sticky) box, bundling and other machines can be completed. (4) the carton strength is reduced less.

由于柔印是轻压印刷,所以对瓦楞纸板的强度影响很小。(5)印刷精度不高,常规胶印加网线数为175线/英寸,而柔印纸箱常规加网线数字为35线/英寸~65线/英寸,属于低精度印刷方式,适合印刷文字线条稿,四色图像印刷质量近年来虽有提高,但仍有局限。

Because flexo printing is light pressure printing, it has little effect on the strength of corrugated paperboard. (5) the printing accuracy is not high, the conventional offset printing screen line number to 175 lines per inch, while conventional screen digital flexo carton 35 lines per inch ~65 lines per inch, which belongs to the low precision of printing, the most suitable for printing text line is printed four-color image quality in recent years has increased, but there are still limitations.

丝印

Screen printing

丝印是离我们生活近的印刷方式。常见的局部UV就是丝网印刷,根据网版的厚度可以形成油墨堆积,有非常好的立体感;丝印也广泛应用于不干胶标签印刷。

Screen printing is the closest way to print our lives. Common local UV is screen printing, according to the thickness of the screen can form ink accumulation, there is a very good three-dimensional feeling; screen printing is also widely used for self-adhesive label printing.

小时候,我们的考试卷子是誊写版油印的,老师把蜡纸垫在有网纹的钢板上,用尖尖的刻字笔刻字,然后用油印机印刷。

When I was young, our examination papers is Roneo mimeographed, teacher put the cushion in netted plate, with the sharp pen lettering lettering, and mimeograph printing.

这种印刷方式就跟我们的丝印是一样的原理:网版有镂空的部分,油墨通过孔眼转移到承印物(纸张、陶瓷等)上,形成图象或文字。除了空气和水,丝印可以在任何东西上面印刷!说的是丝印的对象广泛,电器产品上面的图案文字也是丝印上去的。

This printing method is the same as our screen printing principle: the screen has a hollow part, the ink through the hole transfer to the substrate (paper, ceramic, etc.), to form images or text. In addition to air and water, screen printing can be printed on anything! It is said that the objects of screen printing are extensive, and the patterns on the electrical appliances are also printed on the screen.
