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、對(duì)原紙的要求：對(duì)每批原紙進(jìn)行嚴(yán)格的檢驗(yàn)，檢驗(yàn)指標(biāo)包括厚度、挺度、定量、水分、顏色、表面張力、轉(zhuǎn)移膜粘接牢度、鐳射圖案等，逐一與技術(shù)標(biāo)準(zhǔn)的一概不用，這樣就避免了因原紙有色差等問(wèn)題。

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、對(duì)油墨的要求：要求油墨供應(yīng)商對(duì)標(biāo)樣印刷所用油墨進(jìn)行定量分析，主要包括油墨的強(qiáng)度、灰度、色相誤差、著色力、透明度、粘度、細(xì)度、顏色穩(wěn)定性等指標(biāo)，以此作為油墨的技術(shù)標(biāo)準(zhǔn)。油墨供應(yīng)商所供每批油墨需提供詳細(xì)、真實(shí)的指標(biāo)檢測(cè)數(shù)據(jù)，并與標(biāo)準(zhǔn)油墨指標(biāo)比對(duì)，符合各項(xiàng)內(nèi)控指標(biāo)時(shí)才能投入使用，這樣就能有效避免以往憑主觀判定油墨適用性，沒(méi)有對(duì)油墨進(jìn)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、注重對(duì)印刷設(shè)備的檢修調(diào)整：定期對(duì)墨槽進(jìn)行清洗，確保墨匙動(dòng)作靈活到位。查看水輥、墨輥、擺駕有無(wú)磨損現(xiàn)象。用塞規(guī)、印制墨杠等方法檢驗(yàn)印刷壓力，使之與預(yù)設(shè)值保持一致。測(cè)量橡皮布及印版厚度，使之與標(biāo)準(zhǔn)數(shù)據(jù)相符。及時(shí)更換達(dá)到使用壽命的UV燈，避免因UV燈功率衰減而影響油墨固化速度，而影響印刷質(zhì)量。及時(shí)更換達(dá)到規(guī)定印數(shù)的印版，避免因圖案的細(xì)微磨損而影響印刷顏色效果等。

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.

要想處理好印刷顏色差別，就要做好以上三點(diǎn)。正確認(rèn)識(shí)產(chǎn)生印刷色差的若干因素所在，通過(guò)把好印刷工藝和操作技術(shù)關(guān)，不但可以有效地避免這樣和那樣的印刷弊病產(chǎn)生，而且可以較好地保證彩色印刷品的墨色質(zhì)量，印刷出產(chǎn)品，贏得客戶的信任。關(guān)注網(wǎng)站http://www.helloyong.com，了解更多有關(guān)事項(xiàng)！

If you want to deal with the difference of printing color, you must do the above three points well. Correct understanding of several factors that cause color difference in printing can not only effectively avoid such and other printing defects, but also better ensure the ink quality of color printed products, print products and win the trust of customers by controlling the printing process and operation technology.
