曬網機(ji)曝光是需要注意什么(me)

注意(yi)：曝(pu)(pu)光時間過短，會造成感光膠易脫落，線條(tiao)變粗(cu)，阻焊擋點不牢，字(zi)符號(hao)不牢固(gu)等(deng)問題(ti)；而曝(pu)(pu)光時間達長，cts激光直接制版價(jia)錢，會造成顯(xian)影不盡或(huo)線條(tiao)變細等(deng)質量事故的(de)(de)(de)發生(sheng)。因(yin)此，特別建議，準確的(de)(de)(de)曝(pu)(pu)光時間來源于(yu)科學(xue)的(de)(de)(de)實踐(jian)，生(sheng)產中曝(pu)(pu)光定要用(yong)曝(pu)(pu)光計算尺測(ce)定曝(pu)(pu)光時間，然后再(zai)固(gu)定曝(pu)(pu)光時間，切勿憑經驗做事，盲目(mu)作業。
