印刷在当今的社会生活中已经成为了一种主流的宣传方式。比如精装书、名片、宣传单、手册、等等,但是在印刷过程中会产生色差。那么,精装书印刷颜色差别的处理方式有哪些呢?济南精装书制作厂家认为一般是以下三点:
Printing has become a mainstream way of publicity in today's social life. For example, hardcover books, business cards, leaflets, handbooks, etc., but there will be color differences in the printing process. So, what are the ways to deal with color differences in hardcover printing? Jinan hardcover book manufacturers believe that the following three points are generally:
1、对原纸的要求:对每批原纸进行严格的检验,检验指标包括厚度、挺度、定量、水分、颜色、表面张力、转移膜粘接牢度、镭射图案等,逐一与技术标准的一概不用,这样就避免了因原纸有色差等问题。
1. Requirements for base paper: each batch of base paper shall be strictly inspected. The inspection indexes include thickness, stiffness, quantity, moisture, color, surface tension, transfer film adhesion fastness, laser pattern, etc., which are not used one by one with the technical standards, so as to avoid problems such as color difference of base paper.
2、对油墨的要求:要求油墨供应商对标样印刷所用油墨进行定量分析,主要包括油墨的强度、灰度、色相误差、着色力、透明度、粘度、细度、颜色稳定性等指标,以此作为油墨的技术标准。油墨供应商所供每批油墨需提供详细、真实的指标检测数据,并与标准油墨指标比对,符合各项内控指标时才能投入使用,这样就能有效避免以往凭主观判定油墨适用性,没有对油墨进行定量分析而造成的印刷色差。
2. Requirements for ink: the ink supplier is required to conduct quantitative analysis on the ink used for standard sample printing, mainly including the strength, gray scale, color phase error, coloring power, transparency, viscosity, fineness, color stability and other indicators of the ink, which is used as the technical standard of the ink. Each batch of ink provided by the ink supplier needs to provide detailed and true index detection data, and compare it with the standard ink index. It can be put into use only when it meets various internal control indexes. This can effectively avoid the printing color difference caused by the subjective judgment of ink suitability and the lack of quantitative analysis of ink.
3、注重对印刷设备的检修调整:定期对墨槽进行清洗,确保墨匙动作灵活到位。查看水辊、墨辊、摆驾有无磨损现象。用塞规、印制墨杠等方法检验印刷压力,使之与预设值保持一致。测量橡皮布及印版厚度,使之与标准数据相符。及时更换达到使用寿命的UV灯,避免因UV灯功率衰减而影响油墨固化速度,而影响印刷质量。及时更换达到规定印数的印版,避免因图案的细微磨损而影响印刷颜色效果等。
3. Pay attention to the maintenance and adjustment of printing equipment: wash the ink tank regularly to ensure that the action of the ink spoon is flexible and in place. Check whether the water roller, ink roller and pendulum drive are worn. Check the printing pressure with plug gauge, printing ink bar and other methods to make it consistent with the preset value. Measure the thickness of the blanket and printing plate to make it consistent with the standard data. Timely replace the UV lamp that has reached its service life to avoid affecting the curing speed of ink and printing quality due to the attenuation of UV lamp power. Replace the printing plate with the specified number of prints in time to avoid the effect of printing color due to the slight wear of the pattern.
要想处理好印刷颜色差别,就要做好以上三点。正确认识产生印刷色差的若干因素所在,通过把好印刷工艺和操作技术关,不但可以有效地避免这样和那样的印刷弊病产生,而且可以较好地保证彩色印刷品的墨色质量,印刷出产品,赢得客户的信任。关注网站
