Nā mīkini paʻi Flexographic, e like me nā mīkini ʻē aʻe, ʻaʻole hiki ke hana me ka ʻole o ka friction. ʻO ka lubrication ka hoʻohui ʻana i kahi papa o ka mea wai-lubricant ma waena o nā ʻili hana o nā ʻāpana e pili ana kekahi i kekahi, i hiki ai i nā ʻāpana ʻinoʻino a ʻaʻole like ma ka ʻili hana o nā ʻāpana ke pili iki, i hiki ai iā lākou ke hana i ka friction liʻiliʻi ke neʻe lākou me kekahi. friction. ʻO kēlā me kēia ʻāpana o ka mīkini paʻi flexographic he ʻano metala, a loaʻa ka friction ma waena o nā metala i ka wā o ka neʻe ʻana, kahi e pale ʻia ai ka mīkini, a i ʻole e emi ka pololei o ka mīkini ma muli o ke komo ʻana o nā ʻāpana paheʻe. I mea e hōʻemi ai i ka ikaika friction o ka neʻe ʻana o ka mīkini, e hōʻemi i ka hoʻohana ʻana i ka ikehu a me ke komo ʻana o nā ʻāpana, pono e lubricated maikaʻi ʻia nā ʻāpana pili. ʻO ia hoʻi, e hoʻokomo i ka mea lubricating ma ka ʻili hana kahi e pili ai nā ʻāpana, i hoʻemi ʻia ka ikaika friction i ka liʻiliʻi loa. Ma waho aʻe o ka hopena lubricating, loaʻa pū kekahi i ka mea lubricating:
① hopena hoʻoluʻolu;
② hopena hoʻopuehu koʻikoʻi;
③ Hopena pale lepo;
④ Ka hopena anti-popo;
⑤ Ka hopena hoʻopili a me ka haʻalulu.
