画册印刷中专色和四色的不同之处!

  包装产品或是书刊的封面经常由不同颜色的平均色块或有规律的突变色展现会和文字组成的。这些色块和文字能够分色后采用四色原色油墨相撞而成的。也能够分配专色墨印刷,然后在同一色块处只印刷某一种专色墨。在综合思索进步印刷质量和俭省套印的次数的状况下,有时要选择专色墨来印刷。

  Packing products or book covers are often made up of average color blocks of different colors or regular abrupt color exhibitions and text. These color blocks and text can be separated by four-color primary ink collision. It is also possible to distribute spot ink printing and then print only one kind of spot ink at the same color block. Under the condition of synthetically considering the improvement of printing quality and economizing the number of overprints, spot ink is sometimes chosen for printing.

  专色与四色墨相撞出来的色块其颜色的视觉效果有什么不同呢?

  What's the difference between spot color and four-color ink?

  专色印刷所分配出的油墨的依照色料的减色法混合原理取得的颜色的,其颜色明度较低,饱和度较高。墨色平均的实底采用专色印刷。在恰当的加大墨量,墨层厚度较厚的改动对颜色变化的灵活的会降低。所以更容易得到墨色平均、厚实的印刷效果。

  The color of ink allocated by spot-color printing is obtained according to the principle of subtractive mixing of colors. The brightness of the color is low and the saturation is high. The average solid background of ink is printed in spot color. With proper increase of ink content, the flexibility of color change caused by thicker change of ink layer will be reduced. So it is easier to get the average ink, thick printing effect.

  采用四色印刷的色块。由于组成的该色块的各种颜色大都由一定的比例的网点组成。印刷网点时,墨层的厚度必需遭到严厉的控制。容易因墨层的厚度的改动而产生较大的色差。

  A block of four-color printing. Because the various colors of the color block are mostly composed of a certain proportion of dots. When printing dots, the thickness of ink must be strictly controlled. It is easy to cause large chromatic aberration due to the change of ink thickness.

  假如不能用多色机一次印刷出来的颜色,还容易因半废品的颜色不易控制呈现色偏。所在普通不采用四色印刷,而采用专色印刷。这也就是很多印刷厂单色,双色机印刷专色。四色,8色印刷四色较多。5色普通印刷四色加一个专色或是过油等。

  If you can't use a polychromatic machine to print out the color at one time, it is also easy because the color of semi-waste products is not easy to control the color deviation. It usually does not use four-color printing, but uses spot-color printing. This is also the monochrome and dichroic printing spot color in many printing plants. Four colours, eight colours printing four colours more. Five colours ordinary printing four colours plus a spot colour or oil, etc.
