隨著印刷技術(shù)的發(fā)展，印刷工藝也變的越來越豐富。但是印刷中會(huì)出現(xiàn)印刷品墨色不均勻，是什么原因?qū)е碌哪兀?
With the development of printing technology, printing technology has become more and more abundant. But in printing, the ink color of printed matter is not uniform. What is the reason?
1.有時(shí)人為的疏忽可能會(huì)導(dǎo)致?lián)Q橡皮布時(shí)襯墊紙壓力測量不準(zhǔn)確，這種情況對(duì)于印刷一般活件影響并不大，但大平網(wǎng)活件很“嬌氣”，任何一點(diǎn)調(diào)節(jié)不當(dāng)都會(huì)直接反映在印品上。為此，我們更換新的襯墊紙后重新開機(jī)印刷，但印品墨色不勻現(xiàn)象依然存在，故此種原因排除。
1. Sometimes, human negligence may lead to inaccurate measurement of the pressure of the backing paper when changing the blanket. This situation has little impact on the printing of ordinary moving parts, but the large flat screen moving parts are "delicate", and any improper adjustment will be directly reflected on the printed products. For this reason, we started printing again after replacing the new backing paper, but the uneven ink color of printed products still exists, so this reason is eliminated.
2.仔細(xì)觀察紙張后發(fā)現(xiàn)紙張靠身部位的布紋比靠外的粗糙，布紋涂布不勻，當(dāng)以45°視角側(cè)面觀察時(shí)，涂布不勻現(xiàn)象十分明顯，于是將紙張掉頭后印刷，發(fā)現(xiàn)墨色不均部位轉(zhuǎn)移到另一側(cè)。由此可以判斷產(chǎn)生印品墨色不勻現(xiàn)象的主要原因是紙張布紋涂布不勻，于是聯(lián)系材料科更換紙張后，墨色不勻現(xiàn)象立即消失。
2. After careful observation of the paper, it was found that the cloth pattern on the side of the paper was coarser than that on the outside, and the cloth pattern was unevenly coated. When viewed from the side of 45 ° angle of view, the unevenness was very obvious, so the paper was turned around and printed, and it was found that the uneven ink color was transferred to the other side. Therefore, it can be judged that the main reason for the uneven ink color of printed products is the uneven coating of the paper fabric. Therefore, after contacting the material department to replace the paper, the uneven ink color immediately disappeared.
3.橡皮布使用時(shí)間過長易發(fā)生老化現(xiàn)象，或者因一些部位長時(shí)間被壓致使橡皮布?jí)毫Σ粍?，都有可能?dǎo)致印品出現(xiàn)墨色不勻現(xiàn)象。于是，我們更換了一塊新橡皮布后重新開機(jī)印刷，但故障仍然存在，故此種原因排除。
3. If the blanket is used for a long time, it is prone to aging, or some parts are pressed for a long time, resulting in uneven blanket pressure, which may lead to uneven ink color of printed products. Therefore, we replaced a new blanket and started printing again, but the fault still existed, so this reason was eliminated.
以上就是印刷品墨色不均勻的原因，另外印前設(shè)備大部分是由的電氣元件和集成電路組成，對(duì)溫度和濕度特別敏感，過高和過低的溫度與濕度都會(huì)影響設(shè)備的使用壽命。溫度太高會(huì)影響設(shè)備散熱，溫度太低又有可能造成設(shè)備長時(shí)間預(yù)熱，影響使用。
These are the reasons for the uneven ink color of printed products. In addition, most of the prepress equipment is composed of advanced electrical components and integrated circuits, which are particularly sensitive to temperature and humidity. Too high and too low temperature and humidity will affect the service life of the equipment. Too high a temperature will affect the heat dissipation of the equipment, and too low a temperature may cause the equipment to be preheated for a long time and affect the use.
