產生這種故障的原因有:一是壓痕底模的槽寬選擇不合適;二是刀模版上的線縫太寬,壓痕線在模切壓力作用下發生扭動。解決辦法是更換刀模版。

印刷公司壓痕線不規則的工藝故障和處理

產生這種故障的原因有:

一是壓痕底模的槽寬選擇不合適;

二是刀模版上的線縫太寬,壓痕線在模切壓力作用下發生扭動。


解決辦法是更換刀模版。

印品折疊成型時,壓痕處開裂印品經模切後折疊成型時,會出現壓痕處開裂現象。

紙張壓痕外側開裂,其原因是模切壓力過大,壓痕底模的槽深不夠,因此應根據紙張厚度選用合適寬度的壓痕底模,或將壓痕線的高度改低一些;若紙張內側開裂,則因為模切壓力過大使紙張的纖維斷裂,這就需要查看紙張是整版開裂還是局部開裂,局部開裂時可適當減少壓痕線的墊紙厚度,整版開裂時可適當減小模切壓力同時將壓痕線的高度改低一些。
