He aha nā ʻano pāpaʻi ʻekolu?

ʻO ka pāpaʻi paʻa liʻiliʻi, i hoʻopaʻa ʻia no ka paʻi ʻana i nā manaʻo e hoʻohui i nā halftones a me nā mea paʻa i loko o kahi pā hoʻokahi. He kūpono no nā substrates a pau i hoʻohana mau ʻia a me nā mea ʻole i hoʻopaʻa ʻia (ʻo ia hoʻi ka plastic a me ka alumini pepa, nā papa i uhi ʻia a ʻaʻole i uhi ʻia, preprint liner). ka loaʻa ʻana o nā kiko liʻiliʻi ma ka hapalua.

ʻIke ʻia nā papa paʻi offset no ko lākou hiki ke hana i nā kiʻi hoʻonā kiʻekiʻe a me nā kikoʻī kikoʻī, e kūpono ai ia no ka paʻi ʻana i nā mea e like me nā makasina, nā brochures a me ka ʻeke. Hāʻawi pū lākou i ka pono o ka hoʻololi wikiwiki a me ka maʻalahi o ka pā, ka hopena i ka wikiwiki o ka huli ʻana o ka hana.

ʻO ka paʻi paʻi Flexographic, ka paʻi Flexographic, a i ʻole ka paʻi flexographic, kahi koho kaulana no ka paʻi ʻana ma nā substrate maʻalahi e like me ka plastic, ka pepa, a me ka pahu pahu. Hana ʻia nā pāpaʻi paʻi Flexographic i ka ʻōpala a i ʻole nā ​​mea photopolymer a kau ʻia ma luna o nā wili no ke kaʻina paʻi. Hoʻolālā ʻia kēia mau papa e hoʻololi i ka ʻīnika i kahi substrate me ka hoʻohana ʻana i kahi hoʻomaha maʻalahi e kūlike me nā contours o ka ʻili paʻi.

ʻO nā pā photopolymer ka mea maʻamau i hoʻohana pinepine ʻia i ka paʻi flexographic. Hana ʻia lākou ma ka hoʻolaha ʻana i kahi mea photopolymer ma o ke kukui UV maikaʻi ʻole, e paʻakikī ana i nā wahi kiʻi me ka waiho ʻana i nā wahi kiʻi ʻole i palupalu a hiki ke holoi ʻia. Hiki i ke kaʻina hana ke hoʻopuka kiʻi pololei a paʻa, e hana i nā papa photopolymer i kūpono no ka paʻi ʻana i nā lepili, ka ʻeke a me nā pahu corrugated.

ʻIke ʻia nā papa paʻi Flexographic no ko lākou hiki ke hoʻopaʻa i nā ʻano inks a me nā substrates, e kūpono ana iā lākou no nā ʻano noi like ʻole i ka ʻoihana paʻi a me ka lepili. Hāʻawi pū lākou i nā mana paʻi kiʻekiʻe, e hoʻolilo iā lākou i koho kūpono no ka paʻi kiʻekiʻe.

ʻO ka paʻi paʻi gravure, ka paʻi gravure, ʻike ʻia hoʻi ʻo ka paʻi gravure, he kaʻina paʻi kiʻekiʻe, kiʻekiʻe-nui i hoʻohana mau ʻia no ka hana ʻana i nā makasina, catalogs, a me nā paʻi hoʻonaninani. Hana ʻia nā papa paʻi gravure me ke keleawe a i ʻole ke kila chromed a loaʻa nā pūnae a i ʻole nā ​​lua e paʻa ai ka ʻīnika. Ua kālai ʻia a kālai ʻia ke kiʻi ma luna o ka pā me ka hoʻohana ʻana i ke kaʻina hana kemika a i ʻole ka mīkini, e hana ana i ke ʻano o nā cell e pili ana i ke kiʻi i makemake ʻia.

ʻO nā ʻano nui ʻelua o nā papa paʻi gravure he cylinder a me ka papahele. Hoʻopili ʻia nā papa cylinder a puni ka cylinder a hoʻohana ʻia no ka paʻi mau ʻana, ʻoiai ʻo nā papa pālahalaha e hoʻohana ʻia no nā holo paʻi pōkole a me nā noi kūikawā. Hiki i nā pāpaʻi paʻi Gravure ke hana i nā kikoʻī maikaʻi a me nā ʻano leo ākea, e kūpono iā lākou no ka hana hou kiʻi kiʻekiʻe.

ʻIke ʻia nā papa paʻi gravure no ko lākou lōʻihi a me ka lōʻihi o ka paʻi ʻana, e lilo ana lākou i koho mua no nā hana paʻi kiʻekiʻe. Hiki iā lākou ke paʻi ma nā ʻano substrate like ʻole, e like me ka pepa, ka plastic a me ka metala, e kūpono ana iā lākou no nā noi paʻi like ʻole.

ʻO ka hōʻuluʻulu manaʻo, he mea koʻikoʻi ka paʻi ʻana i ka ʻoihana paʻi, a he mea koʻikoʻi ka hoʻomaopopo ʻana i nā ʻano like ʻole o nā papa paʻi i ke koho ʻana i ke ala kūpono no kahi hana paʻi kikoʻī. ʻO nā pāpaʻi paʻi offset no ka paʻi pāʻoihana hoʻonā kiʻekiʻe, nā papa paʻi flexographic no ka hoʻopili maʻalahi, a i ʻole gravurepapa paino nā paʻi puke kiʻekiʻe, hāʻawi kēlā me kēia ʻano paʻi i nā pono kūʻokoʻa a me ka hana. Ma ke koho ʻana i ka pā paʻi kūpono, hiki i nā mea paʻi ke hoʻokō i ka maikaʻi o ka paʻi a me ka pono e pono ai lākou no kā lākou pono paʻi kikoʻī.
