ʻO ka mālama ʻana no ka hoʻopili ʻana a me ka paʻi ʻana i ka QR Code

ʻO ka mālama ʻana no ka hoʻopili ʻana a me ka paʻi ʻana i ka QR Code

Hiki i ka QR code ke ʻeleʻele monochrome a i ʻole nā ​​kala he nui.ʻO nā kumu nui e pili ana i ka maikaʻi o ka paʻi code QR ʻo ka ʻokoʻa kala a me nā hewa overprinting.

1. ʻOkoʻa kala

ʻAʻole lawa ka ʻokoʻa kala o ka nūpepa QR code e pili ana i ka ʻike ʻia o ka QR code e ka polokalamu kelepona paʻa.ʻO nā hiʻohiʻona Optical nā koi o nā hōʻailona paʻi barcode: I mea e heluhelu hilinaʻi ai, ma hope o ka paʻi ʻana, pono e ʻike ʻia nā laina a me nā hakahaka o ka barcode, ʻoi aku ka nui o ka noʻonoʻo ʻana o nā hakahaka, a ʻo ka noʻonoʻo ʻana o nā laina. liʻiliʻi e like me ka hiki.Wahi a ke kūlana aupuni, ʻoi aku ka keʻokeʻo o ka nūpepa kūloko ma mua o 50%, a hiki i ka paʻi maʻamau ke hoʻokō i nā koi ʻike o QR code.Eia nō naʻe, pono e hoʻomaopopo ʻia i ka wā e hana ai i kahi QR code ma kahi nūpepa, pono e hoʻomanaʻo ʻia ka mea hoʻoponopono ʻaʻole e hoʻohui i ka pale e pale ai i ke kūlana kahi i lawa ʻole ai ka ʻokoʻa i ka heluhelu ʻana.

2. Ke kuhi hewa

E pili ana i ke code QR kala.Pono a maʻemaʻe ka QR code i ka paʻi ʻana.ʻO ka mea maʻamau, ʻōlelo mākou ʻo ka nui o ka nui o ka hewa o ka overprint (ka hewa overprint ma waena o ke kala nui a me ke kiʻi) pono e emi a i ʻole like me 0.4 mau manawa o ka laula inoa o ka barcode laina haiki.

E like me ke kūlana aupuni, pono ka hewa o ka paʻi ʻana o nā nūpepa ma lalo o a i ʻole like me 0.3mm.ʻO kaʻoiaʻiʻo, hiki i kekahi mau nūpepa ma luna a i ʻole ka pae panalāʻau me nā lako paʻi kiʻekiʻe a me nā koi ʻoi aku ka maikaʻi e hiki ke hoʻokō piha i nā kūlana ma kēia ʻano.No kekahi mau nūpepa kūloko a me ke kūlanakauhale, inā ʻaʻole paʻa ka overprinting, pono e paʻi ʻia ka QR code i hoʻokahi kala, i ʻole pilikia ka overprinting.

Ke pa'i 'ole nei kekahi mau mea

I ka paʻi ʻana, e makaʻala ʻaʻole e nalowale nā ​​mea ma ka pā paʻi, i ʻole e pilikia i ka heluhelu ʻana i ke code QR.I ka paʻi ʻana, ma muli o ka paʻi paʻi ʻana a i ʻole ka pale, maʻalahi ke kumu i ka hemahema o ke ʻano paʻi.No ke ʻano o ka "fragmented" liʻiliʻi o ke code ʻelua-dimensional, pono e uku nui ʻia i ka pre-press a post-check.

Paʻi ʻīnika pilikia

No ka mālama ʻana i ka hewa nui o ka hōʻailona code ʻelua-dimensional, ʻo ke kī ke hoʻomalu i ka waihoʻoluʻu ʻīnika a me ke kaomi paʻi ʻana i ka wā e paʻi ana e hōʻoia i ka hoʻihoʻi pololei ʻana o nā kaha code ʻelua-dimensional.Ma lalo o nā kūlana maʻamau, pono mākou e hōʻoia i ka'īnika he "liʻiliʻi i ka wai a liʻiliʻi i ka'īnika", a ma ka manawa like e hōʻoia i ka mānoanoa kūpono o ka'īnika.ʻAʻohe ala hoʻopunipuni ma muli o ke kaomi haʻahaʻa a i ʻole lawa ʻole ke kala ʻīnika;ʻaʻohe hoʻopuehu streak ma muli o ke kaomi nui a i ʻole ka inika nui.
