紙箱廠家是怎么解決印刷重影和露白問題的?

來源:http://www.xmntn.com 時間:2020-05-04

  很多濟南紙箱生產廠家都會遇到印刷重影和露白的問題,這是在紙箱生產過程中經常出現的兩個問題,如何才能正確解決這一問題呢?
  Many Jinan carton manufacturers will encounter the problem of printing double shadow and exposed white, which are two problems that often appear in the carton production process. How can we solve this problem correctly?
  印刷圖案或文字周圍出現重影,是因為網紋輥與印版的壓力過大引起的;印字前部邊緣出現重影,則是因為印刷滾筒與壓印輥之間的壓力過大引起;大面積印刷透、漏白又是由于印刷輥與壓印輥壓力不夠所產生。
  The double shadow around the printed pattern or text is caused by the excessive pressure between the anilox roller and the plate; the double shadow at the front edge of the printed word is caused by the excessive pressure between the printing roller and the imprinting roller; the bottom penetration and white leakage of large-area printing are caused by the insufficient pressure between the printing roller and the imprinting roller.
  解決印刷重影問題應當調整網紋輥和版輥之間的間隙和壓力(俗稱上壓力)。
  The gap and pressure between anilox roll and plate roll (commonly known as upper pressure) should be adjusted to solve the problem of printing duplication.

  重影是因為上壓力過大,網紋輥擠壓印刷版(指柔性版)變形產生,因此要增加兩輥的間隙,相應減少壓力。
  The reason for ghosting is that the overpressure causes the anilox roll to extrude the printing plate (referring to the flexible plate) to deform. Therefore, the gap between the two rolls should be increased and the pressure should be reduced accordingly.
  解決印刷漏白問題則應調整版輥與壓印輥之間的間隙和壓力(俗稱下壓力)。由于版輥和壓印輥間隙過大,遇大面積印刷產生不實,這就需要加大下壓力。另外,印刷版不平整、版襯、印版硬度等質量都會影響到上述問題的產生,應進行局部調整。
  To solve the problem of printing white leakage, the gap and pressure between the plate roller and the press roller should be adjusted (commonly known as the down pressure). As the gap between the master roll and the press roll is too large, in case of large-area printing, it is not true, which needs to increase the down pressure. In addition, the uneven printing plate, plate lining, plate hardness and other quality will affect the above problems, so local adjustment should be made.
