印刷廠跟著社會的開展,開展空間在不斷的提高,當(dāng)咱們在印刷的時分,色彩的位置是十分高的,而作業(yè)人員需求具有色彩處理的辦法,下面小編就給我們介紹一下怎么做好色彩的處理:
With the development of the society, the printing factory's development space is constantly improving. When we are printing, the position of color is very high, and the operators need color processing methods. The following sections will introduce how to do color processing well:
一、印刷進(jìn)程中
1、 Printing in progress
1、呈現(xiàn)墨色不實(shí)的原因許多,其觸及的要素也許多,包含紙張的功能、油墨的功能、印版的質(zhì)量、印刷橡皮布 的質(zhì)量、印刷壓力、印刷機(jī)的功能和印刷工藝等方面。
1. There are many reasons why ink color is not solid, and many elements are involved, including paper function, ink function, printing plate quality, printing blanket quality, printing pressure, printing machine function and printing technology.
2、假如紙張、油墨的功能安穩(wěn),印版制造質(zhì)量滿意了印刷要求,印刷機(jī)作業(yè)功能相對安穩(wěn)的話,仍是呈現(xiàn)了墨色印刷不實(shí)現(xiàn)象,其首要發(fā)生的原因便是印刷壓力的問題了。
2. If the functions of paper and ink are stable, the printing plate manufacturing quality meets the printing requirements, and the printing machine operation function is relatively stable, the ink printing is still not true. The primary reason is the problem of printing pressure.
二、在平版膠印進(jìn)程中常會碰到色彩印不實(shí)的現(xiàn)象,在印刷品上首要體現(xiàn)為印品實(shí)地部分有斑駁或發(fā)虛,圖文或線條殘缺不全,圖畫的階調(diào)層次再現(xiàn)性差或網(wǎng)點(diǎn)丟掉。
2、 In the process of offset printing, we often encounter the phenomenon of false color printing, which is mainly reflected in the printed matter that the real part of the printed matter is mottled or blurry, the image and text or lines are incomplete, the level reproducibility of the picture is poor, or the dot is lost.
三、在膠印中
3、 In offset printing
1、壓力的巨細(xì)直接決議了印刷進(jìn)程中油墨的搬運(yùn),如印刷進(jìn)程中呈現(xiàn)部分的壓力不均,將導(dǎo)致印刷墨色的不實(shí)。
1. The size of the pressure directly determines the ink handling in the printing process. If the pressure of the presented part in the printing process is uneven, it will lead to the uneven printing ink color.
2、因?yàn)橄鹌L筒安裝在印版滾筒和壓印滾筒之間,橡皮布上的每個細(xì)小單元每旋轉(zhuǎn)一周,都要別離和兩個滾筒各觸摸一次。
2. Because the rubber cylinder is installed between the plate cylinder and the embossing cylinder, each small unit on the blanket must be touched separately from the two cylinders once every rotation.
3、油墨的搬運(yùn)便是橡皮布緊縮變形的成果,橡皮布的緊縮變形是發(fā)生壓力的根本保證,因而,壓力的巨細(xì)及均勻程度與膠印印刷用的橡皮布有著直接聯(lián)絡(luò)。
3. The ink handling is the result of the blanket's compression deformation, which is the fundamental guarantee for the occurrence of pressure. Therefore, the size and uniformity of the pressure are directly related to the blanket used for offset printing.
4、其受力是周期性改動的,正是因?yàn)橄鹌げ际芰Φ闹芷谛愿膭?,會?dǎo)致橡皮布發(fā)生內(nèi)訌,導(dǎo)致橡皮布的老化,影響印刷壓力的均勻性,或許會引起橡皮布的作廢。
4. The force on the blanket is periodically changed. It is precisely because the periodic change of the force on the blanket will lead to the internal conflict of the blanket, lead to the aging of the blanket, affect the uniformity of the printing pressure, and may cause the blanket to be invalid.
5、橡皮布在壓印力的效果下,具有很好的將印版圖文部分的油墨傳遞到承印物外表的才能,即受墨和釋墨才能,可是橡皮布的老化會改動這種油墨傳遞的才能,也會導(dǎo)致墨色不實(shí)的現(xiàn)象。
5. Under the effect of the impression force, the blanket has a good ability to transfer the ink of the image and text part of the printing plate to the surface of the substrate, that is, the ability to receive and release ink. However, the aging of the blanket will change the ability to transfer ink, and will also lead to the phenomenon of ink color.
6、包覆在滾筒上的橡皮布,遭到張緊力和壓力的效果,跟著滾壓次數(shù)的繼續(xù)不斷的添加,橡皮布緊縮變形的應(yīng)力堆集會變得硬挺,失掉原有的柔軟性和高彈性,乃外表會呈現(xiàn)亮光或龜裂的痕跡,因而導(dǎo)致壓力的部分不均勻。
6. The rubber blanket wrapped on the roller is subject to the effect of tension and pressure. With the continuous addition of rolling times, the stress pile of rubber blanket compressed and deformed becomes stiff, losing its original softness and high elasticity, and even the appearance will show signs of light or cracking, resulting in uneven pressure.
