凹版印刷机 凹版印刷机是采用圆压圆直接印刷方式印刷,印版直接制在印版滚筒上,采用浸墨或喷墨方式给墨,没有匀墨机构。由于墨层厚,使用挥发性强的快干油墨,须有烘干装置。欢迎在此版面讨论分享凹版印刷机系列型号操作经验与技术交流!

默认 凹印工艺简述

凹印工艺也有卷筒纸和平板纸印刷机之分,色组和功能也有多种机型,该印刷工艺具有印版耐印率较高,印刷速度较快等特点。由于凹印墨层较厚,印刷墨色饱满而富有立体感,版面印刷层次丰富、质感强,印刷墨色干燥速度较快,故较适合大面积、墨量厚的印刷产品。凹印工艺既可适合印刷实地、专色线条版,又可印刷精细的网纹版,与胶印、柔印或丝印等工艺相比,该工艺最不容易产生印刷色差,纸箱的印刷产品质量是最稳定和最佳的。由于凹印版材是钢辊材料经过电镀、电雕等加工工艺处理制作而成,其制版工艺比较复杂,制版材料和费用也比较昂贵,且换版操作也比较麻烦,所以,特别适合于批量较大宗的预印纸箱印刷生产,才能较好地降低生产成本。

难过 Waiting in a hotel in

?Waiting in a hotel in Dublin's city centre there's a scattering of adolesecents with guitar cases; the place is a like an Irish version of Hogwarths where teenage boys swap magic wands for 'ghd' straighteners. When Yngve joins me with a pint of Guinness he informs me there's music lessons happening, how he knows this I do not know. But nevermind, lets move on with the interview. Yngve comes across much as his music does - matter of fact but slightly dreamy, warm, self-assured but not cocky. He has considered most of the angles and is set on a clear musical vision. His current E.P. 'Have You No Love' is a blues-tinged slice of Americana. ghdghd straightenersghd hair straighteners
