济南喷绘对于颜色把控该如何做?

来源:http://www.hongchenad.cn    发布时间:2020-07-13

在日常喷绘业务中,经常有客户特别是新客户对喷绘成品“偏色”颇有抱怨,甚至因对色彩不满而报废,客户多半会将责任归罪于喷绘公司。客观的说:一定程度上的“偏色”是不可避免的,其中色差过大的原因,相当一部分是出在设计阶段,设计师素质高低及调色经验往往决定了一张画面色彩的好坏,如掌握得当,可以有效的减少或避免偏色造成的损失。

In the daily business of inkjet printing, there are often customers, especially new customers, who complain about the "color deviation" of inkjet products, and even scrap them because of their dissatisfaction with the colors. Most of the customers will blame the inkjet printing company for the responsibility. Objectively speaking: to a certain extent, "color deviation" is inevitable, and a considerable part of the reasons for excessive color difference are in the design stage. The quality of the designer and the experience of color matching often determine the quality of a picture color. If properly mastered, it can effectively reduce or avoid the loss caused by color deviation.
在平时平面设计工作时,客户决定颜色的依据往往是电脑屏幕,因此屏幕色彩的差异、深浅很重要,在Photoshop中进行色彩校正非常关键,没有这个前提,偏色将不可避免。另外相当一部分设计师习惯于在“RGB”模式下做文件,而无论是印刷还是喷绘,色彩更终都是以“CMYK”四色来实现,“RGB”文件的颜色往往显得更鲜艳,部分色彩与“CMYK”差异巨大,因此,养成“CMYK”模式做文件的习惯是减少偏色的重要前提。由于色彩种类数以百万计,电脑屏幕对细微的色彩差异往往难以区分,因此,以颜色数值来控制颜色才是“办法”,设计师对色彩数值的把握往往决定了喷绘画颜色的好坏。例如:大红色“M100,Y100”、深蓝色“C100,M80”,湖蓝“C100,另3色值为0”,黑色“C70,M70,Y70,K95”(如单黑K100,其它为0往往不黑且条纹严重),纯黄色“Y100,其它为0”(如夹杂“C”成份,将变成浅绿色),大色块填充时尽量选择双色填充,少选择3种或4种色值填充,以免增加色彩控制的难度。‘

In ordinary graphic design work, the basis for customers to determine the color is often the computer screen, so the difference and depth of screen color is very important, color correction in Photoshop is very important, without this premise, color deviation will be inevitable. In addition, quite a number of designers are used to making documents in the "RGB" mode. No matter whether it is printing or inkjet printing, the color is ultimately realized by "CMYK". The color of "RGB" file is often more vivid, and some colors are quite different from "CMYK". Therefore, it is an important premise to cultivate the habit of making files in "CMYK" mode to reduce color deviation. Due to the millions of color types, it is difficult to distinguish the subtle color differences on the computer screen. Therefore, it is the "ultimate method" to control the color with the color value. The designer's grasp of the color value often determines the quality of the spray painting color. For example: bright red "M100, Y100", dark blue "C100, M80", lake blue "C100, the other three color values are 0", black "C70, M70, y70, K95" (such as single black k100, others are 0, often not black and have serious stripes), pure yellow "Y100, others are 0" (if mixed with "C" component, it will become light green). When filling large color blocks, double color filling should be selected as much as possible, and 3 or 4 color values should be less selected To avoid increasing the difficulty of color control.
不同喷绘机型,不同幅宽及品牌灯布,不同批次的油墨,甚至不同时间段,喷绘出来的色彩都有差异,喷绘机出图过程中“堵头,抽墨,再堵头,再抽墨”的操作过程,也决定了一定范围内的色彩差异,喷绘极低的利润率导致喷绘公司普遍让喷头“超龄工作”,因此绝对意义上的色彩还原是不可能实现的,向客户解释这些常识非常必要,某些高要求大金额画面,看小样再出大图仍然是必不可少的程序,只有这样,才能有效减少损失。
Different inkjet machines, different widths and brands of lamp cloth, different batches of ink, and even different periods of time have different colors. The operation process of "blocking, inking, blocking and re inking" in the process of inkjet printing also determines the color difference within a certain range. The extremely low profit margin of inkjet printing results in that the spray printing companies generally allow the nozzle to "work over age" This absolute sense of color restoration is impossible to achieve, it is very necessary to explain these common sense to customers. For some high demand and large amount of pictures, it is still necessary to see small samples and then draw large pictures. Only in this way can we effectively reduce losses.
