如何调整外来电子文件的色彩?
作者:金圣印务日期:2017-07-21人气:

  印刷足彩跟单软件推荐企业的很多印刷文件为外来电子文件,印刷企业只需按照外来电子文件输出印版,就可以上机印刷了。但大部分外来电子文件是由广告公司设计的,这就会为印刷企业的色彩控制带来问题。下面,笔者将以河北新华第二印刷有限责任公司对某一活件的处理为例,为大家介绍外来电子文件的色彩处理方法。

  案例介绍

  印刷产品为某公司的《声屏之友》杂志,电子文件为外来电子文件 ,印刷设备为商业轮转印刷机,承印纸张是轻涂纸。生产工艺流程是先拼版,输出数码样张,由客户核对内容和颜色并签字确认,输出CTP版,上机印刷。

  外来电子文件一般由广告公司制作,其基本上是按单张纸胶印机的印刷要求来制作的,阶调值总和为320%~340%,网点增大值为20%,采用GCR分色模式,选择中调黑版,这样的分色设置用单张纸胶印机印刷问题不大,但如果用商业轮转印刷机印刷,就会出现色彩问题。

  由于印刷企业数码打样的色彩管理只做了数码打样机与海德堡四色胶印机的色彩匹配。客户对数码打样的效果很满意,但当用单张纸胶印机的CTP输出曲线输出CTP版,再上商业轮转印刷机印刷时就出问题了:印刷追色困难,印刷效果与数码打样效果差别较大,亮调不亮、暗调不暗,整体感觉颜色偏闷,客户对印刷效果很不满意。

  因此,如果将这样的CTP版直接拿到商业轮转印刷机上进行印刷,可能会出现以下问题:供墨量较小时,图像的中间调颜色合适,而暗调的密度不够,色彩饱和度不好,图像反差小;如果加大供墨量,暗调的饱和度合适了,亮调、中间调会因网点增大严重,造成颜色过深,图片显得灰暗,没有层次,无法追上数码样张。
足彩跟单软件推荐   根据以上分析,我们提出了如下解决方案:通过上一期周刊印刷样张上的印刷测控条得出商业轮转印刷机的网点增大曲线,根据该曲线,重新设置CTP输出参数,以补偿商业轮转印刷机的网点增大。
