在印刷過(guò)程中，版型是否翹曲決定了生產(chǎn)效率。如果版材翹曲，不僅會(huì)影響生產(chǎn)效率，還會(huì)造成很大的生產(chǎn)損失。那么如何印刷翹曲問(wèn)題呢？

In the printing process, whether the plate is warped determines the production efficiency. If the plate warps, it will not only affect the production efficiency, but also cause great production loss. So how to solve the problem of printing warpage?

滾筒上的鎖版裝置松動(dòng)會(huì)導(dǎo)致印版翹曲。鎖版裝置松動(dòng)，印版安裝印刷時(shí)，印版受力松緊，長(zhǎng)時(shí)間使用印版開始發(fā)熱。一旦受熱過(guò)大，粘度就會(huì)降低，到一定程度會(huì)導(dǎo)致印版脫落，印版翹曲。因此，必須定期檢查鎖緊裝置，不能松動(dòng)。一旦松動(dòng)，就會(huì)影響印刷質(zhì)量，還會(huì)出現(xiàn)重影、脫墨、網(wǎng)點(diǎn)堵塞等現(xiàn)象。

Looseness of the plate locking device on the cylinder will lead to warpage of the printing plate. The plate locking device is loose. When the printing plate is installed and printed, the printing plate is tensioned, and the printing plate starts to heat after long-time use. Once heated too much, the viscosity will be reduced, which will lead to the falling off of the printing plate and the warping of the printing plate to a certain extent. Therefore, the locking device must be checked regularly without loosening. Once loose, it will affect the printing quality, and there will be ghosting, deinking, dot blocking and other phenomena.

印版會(huì)翹起，多半是因?yàn)殡p面膠不粘。雙面膠分為白色和黃色兩種。黃色膠帶易撕，貼錯(cuò)容易改變位置，但粘性較差。因此，在制作柔版印刷版時(shí)，白色膠帶優(yōu)于黃色膠帶。用白膠帶貼印版時(shí)，一定要量好距離再采用一定的生產(chǎn)標(biāo)準(zhǔn)，貼版好，不翹邊。

The printing plate will tilt up, mostly because the double-sided tape is not sticky. The double-sided adhesive tape is divided into white and yellow. The yellow tape is easy to tear and paste incorrectly, which is easy to change the position, but the viscosity is poor. Therefore, when making flexographic printing plate, white tape is better than yellow tape. When pasting the printing plate with white tape, be sure to measure the distance, and then adopt a certain production standard to paste the plate well without edge warping.

印刷后存放不當(dāng)也會(huì)導(dǎo)致印版翹曲。許多打印機(jī)存儲(chǔ)卷曲的印版，這會(huì)在印版和底座的邊緣產(chǎn)生張力。在生產(chǎn)過(guò)程中或拆卸印版時(shí)，會(huì)出現(xiàn)黃樟的現(xiàn)象。水在印版的邊緣。水只要卷曲儲(chǔ)存起來(lái)，很容易滲入印版，導(dǎo)致膠帶不粘，造成翹曲。因此，次印刷完成后，應(yīng)將印版鎖緊密封，以免發(fā)生翹曲現(xiàn)象。

Improper storage after printing will also lead to plate warpage. Many printers store curled plates, which creates tension at the edges of the plate and base. In the production process or when disassembling the printing plate, there will be the phenomenon of yellow camphor. Water is on the edge of the printing plate. As long as water is curled and stored, it is easy to penetrate into the printing plate, resulting in non stick tape and warpage. Therefore, after the first printing, the printing plate should be locked and sealed to avoid warpage.
