济南手提袋印刷对于印版的区分方法

一、济南手提袋印刷的层次辨别法

I. Hierarchical Discrimination Method of Handbag Printing in Jinan
关于黑色和黄色来说,这个办法十分适用。普通来说,在四色版中,黑版多以短调复制,因而层次十分少,很容易识别;由于在大局部作品中,黄色的成分都比拟重,所以看起来黄版的层次很满、很糊,也比拟好认。而品红版和青版,层次都差不多,假如没有分色的经历,用这个办法常常容易搞混。
For black and yellow, this method is very applicable. Generally speaking, in the four-color edition, the Black Edition is mostly copied in short tones, so the level is very small and easy to identify; because in most works, the Yellow component is comparable, so it seems that the Yellow edition is full, vague and comparable. The magenta version and the green version have the same level. If there is no experience of color separation, it is often easy to confuse them.

二、特征色辨别法
2. Characteristic Color Discrimination
普通有经历的印前工作者,多用这个办法来辨别。由于它契合分色原理,因而,运用起来精确性很高。我们晓得,经过滤色片的分色后,各色版都有其根本色和相反色。如品红版,其根本色是品红、红、蓝紫色和黑色,相反色是黄、青、绿和白色。
Ordinary experienced pre-press workers often use this method to identify. Because it fits the principle of color separation, it has high accuracy in application. We know that after the color separation of the filter, all the color plates have their fundamental and opposite colors. For example, in the magenta version, the basic colors are magenta, red, blue-purple and black, while the opposite colors are yellow, blue, green and white.
因而,一切的红色、蓝紫色和品红色,在品红的分色胶片上都应该有很深的黑色。我们能够找到一些相关的特征色,如红旗、红色印章、人物的嘴唇等等,这些部位在品红版上都应该是深色,而且青版上则是淡色。相反,一些天空、大海、森林等,在品红上则是淡色,而在青版上是深色。
Therefore, all red, blue-purple and magenta should have deep black on magenta color separation film. We can find some related features, such as red flag, red seal, character's lips and so on. These parts should be dark on the magenta plate and light on the green plate. On the contrary, some skies, seas, forests, etc. are pale in magenta and dark in blue.
三、角度辨别法
3. Angle discrimination
这是借助放大镜,从胶片的分色角度上来察看的。普通来说,黄版的角度总是90°。这是思索到弱色版的特性来停止角度布置的。品红、青、黑由于是强色版,因而必需避开呈现龟纹,多以跟45°相差30°的角度差来布置,即15°、45°、75°。
This is seen through a magnifying glass from the perspective of film color separation. Generally speaking, the angle of yellow edition is always 90 degrees. This is to think about the features of the weak version to stop the angle layout. Because magenta, cyan and black are strong color versions, it is necessary to avoid the appearance of tortoise lines. They are mostly arranged at an angle difference of 30 degrees from 45 degrees, i.e. 15 degrees, 45 degrees and 75 degrees.

济南手提袋印刷强色版的角度可依据原稿的特性来肯定,没有固定的角度。而黄色是弱色版,即便呈现龟纹,人眼也不易察看得到。关于方形网点和圆形网点来说,当在一个象限中无法再布置第四个理想角度时,差的角度就给了它。因而,它的角度都是布置在90°。留意,由于链形点的角度布置是0~180°,因而,关于链形点则另当别论。
Jinan handbag printing strong color plate angle can be confirmed according to the characteristics of the original, there is no fixed angle. And yellow is a weak color version, even with tortoise lines, the human eye is not easy to see. For square and circular dots, when the fourth ideal angle cannot be arranged in a quadrant, the worst angle is given to it. As a result, its angles are all arranged at 90 degrees. Note that since the angle of the chain point is 0-180 degrees, it is different to discuss the chain point.
四、网花辨别法
IV. Discrimination of Net Flowers
假如有样张,还能够应用样张,停止网花辨别法。将一张分色胶片拼放在样张上,稍稍转一个角度,在色彩区部位会呈现一些带颜色的网花,即龟纹。假如呈现的是品红色的网花,则这张胶片是品红版;假如是青色网花则为青版。这是为什么呢?
If there are sample sheets, we can also apply sample sheets and stop the identification of net flowers. Put a piece of color separation film on the sample sheet, turn a little, and there will be some color meshes in the color area, that is, tortoise pattern. If the screen is magenta, the film is magenta; if it is blue, it is blue. Why is that?
济南手提袋印刷的工作人员晓得,当两种网点角度相差越小时,其生成的方块花纹则越大,越明显。当把一张单色胶片放在样张上时,它的角度与四色样张中的本性的角度是一样的,胶片略微转一个角度后,胶片与四色样张中的本性角度差很小,这个很小的角度差就很容易生成一个明显的本性网花。
Jinan handbag printing staff knows that when the angle difference between the two dots is smaller, the larger and more obvious the block pattern is generated. When a monochrome film is placed on the sample, its angle is the same as that of the nature in the four-color sample. When the film is slightly rotated at an angle, the difference between the nature angle of the film and the four-color sample is very small, and this very small angle difference can easily produce a distinct nature net flower.
