印刷品設計為什么需要加出血?

印刷品設計為什么需要加出血?很多企業的設計師在和印刷廠對接的時候講沒有加出血的稿件傳給印刷廠制版人員時候,被要求加出血。很不理解,非要加出血嗎?
Why does print design need bleeding? Designers of many enterprises are required to add bleeding when they communicate with the printing plant that the manuscript without bleeding is transmitted to the plate making personnel of the printing plant. I don't understand. Do you have to add bleeding?
首先,需要強調的是,紙質印刷品印刷設計時都需要加出血。這里不接受不加出血就可以上機印刷的辯論!為什么印刷品需要加出血,實際上是為了降低加工的難度,如果所有加工位置都能準確無誤,那么出血確實沒什么意義,但是由于紙張伸縮以及工序定位等等原因,某些尺寸會有一些誤差,這時出血是保證成品率的關鍵。
First of all, it should be emphasized that bleeding needs to be added in the printing design of paper printing. The debate that we can print without bleeding is not accepted here! The reason why printing materials need bleeding is actually to reduce the difficulty of processing. If all processing positions can be accurate, bleeding really doesn't make sense, but some sizes will have some errors due to paper expansion and process positioning. At this time, bleeding is the key to ensure the yield.

比如你做一個廣告宣傳單,宣傳單是一個直徑為15厘米圓形,圖文是在整個綠色底上印刷紅色字和其他圖文,這時印刷底色時,不能恰好印刷15厘米的圓,必須多印刷0.5厘米,也就是說印刷綠色時是印刷15.5厘米的圓形,再印其他圖文。這樣,印刷和模切位置誤差超過0.5厘米才會露白。如果沒有這個出血,必須一點不差,這很難。
For example, if you make an advertising leaflet, the leaflet is a circle with a diameter of 15 cm, and the text is printed with red words and other text on the whole green background. At this time, when printing the background color, you can't just print a circle of 15 cm, and you must print 0.5 cm more, that is, when printing green, you print a circle of 15.5 cm, and then print other text. In this way, the printing and die-cutting position error will be exposed only when it exceeds 0.5cm. If there is no bleeding, it must be not bad, which is difficult.
其次,不論是現在印刷技術多么先進,工序多么協同,總會有誤差。特別是在環境溫度不可控的情況下,人工裁切和模切時不可避免會出現偏離的情況。這個出血,就是為了讓偏離有糾正的機會。
Secondly, no matter how advanced the printing technology and how collaborative the processes are, there will always be errors. Especially when the ambient temperature is uncontrollable, deviation will inevitably occur during manual cutting and die cutting. This bleeding is to give the deviation a chance to correct.
再次,為什么需要加3mm出血?這是在長期的實踐過程中,總結出來的。當然有些印刷品加的出血可能小,比如名片拼版印刷的時候只需要加1.5mm的出血即可;再比如,彩色瓦楞紙箱在印刷裱紙的時候需要加不少于5mm的出血。當然單頁或者海報在尺寸不允許的情況下,也可以加2mm的出血。這都是可以靈活對待的,可以少加出血但是不能不加出血!
Again, why add 3mm bleeding? This is summed up in the process of long-term practice. Of course, the bleeding of some printed materials may be small. For example, when making up business cards, only 1.5mm bleeding is needed; For another example, the color corrugated box needs to add no less than 5mm bleeding when printing and mounting paper. Of course, when the size of a single page or poster is not allowed, 2mm bleeding can also be added. This can be treated flexibly. You can add less bleeding, but you can't do without bleeding!
好了小伙伴們,關于印刷品為什么需要加出血,加多少出血的問題就和大家探討到這里,歡迎在線留言交流!
All right, guys, let's discuss why and how much bleeding should be added to printed matter. Welcome to leave messages online!
