Izinyathelo zokuphepha zokwenza izinkomishi zephepha (1)

1. Isikhunta Sommese
Inkomishi yephephas zingahlukaniswa zibe ama-ounces angu-3, ​​4, 5, 6.5, 7, 8, 9, 10, no-12 ngokosayizi wawo. Ubude obuhambisanayo bungu-5.2, 6, 7, 7.3, 7.6, 8.4, 8.8, 9.3, no-11.7cm ngokulandelana. Ngenxa yokucaciswa okuhlukile, usayizi wokufa ohambelana nawo uhlukile. Kwesinye isikhathi isikhunta sommese singabiza imibhalo eyenziwe ngaphambili, kepha amanye amakhasimende anezilinganiso ezikhethekile zesikhunta sommese, okufanele sidonswe ngokuya ngosayizi oshiwo, futhi kufanele siphrinte ngaphezulu ngemuva komdwebo (isikhunta sommese sayo yonke imikhiqizo ye-flexographic kufanele iphrintwe ngokweqile). Bese udala isendlalelo esisha bese udweba imibuthano emibili, ehambisana nefa langaphandle, bese usebenzisa le mibuthano emibili ukuze uhlanganise imibuthano eminingi ngethuluzi lokuhlanganisa.
2. Hlela imibala
Inani elikhulu lemibala yamabala livame ukusetshenziswa ekuphrinteni kokupakisha, okwandisa ubunkimbinkimbi benqubo. Kunezizathu eziningi zokusebenzisa imibala yamabala:
Okokuqala, ngokuvamile akunakwenzeka ukusebenzisa inhlanganisela yemibala emithathu eyinhloko ye-hue ekuphrinteni kwamaphakheji, ikakhulukazi leyo mibala ehlanzekile, ekhanyayo kanye nemibala ethile ekhethekile.
Okwesibili, ilogo yenkampani ivame ukuphrintwa emaphaketheni omkhiqizo. Lezi zimpawu ngezinye izikhathi ziyimibala yangaphakathi yenkampani yokuklama. Nakuba le mibala ingaxutshwa nemibala emithathu eyinhloko, imibala yamabala iyadingeka ezikhathini eziningi.
Okokugcina, ekuphrinteni kokupakisha, imibala yamabala ivamise ukusetshenziselwa ukuhlukaniswa kombala wezithombe ze-halftone. Eqinisweni, lapho unyathelisa ikhofi noma elinsundu, esikhundleni sokusebenzisa okuphuzi, i-magenta, i-cyan, nokumnyama, kulula futhi kulula ukuliphrinta ngoyinki owodwa onsundu, futhi umphumela wombala ngemva kokunyathelisa ubonakala ungokoqobo. Ngakho-ke, ekunyatheliseni kwe-flexo, lapho uthola umbhalo wesandla wekhasimende, kufanele kuqala kube nomuntu okhethekile wokwenza ukucubungula ukuhlukaniswa kombala, bese abasebenzi bokukhiqiza bazowukhiqiza ngomphumela wokuhlukaniswa kombala. Zama ukwenza yonke imibala ingashintshwa ngemibala yebala. Kodwa ngezinye izikhathi ubuye wenziwa ngemibala egqagqene, ngokuvamile ngenxa yokuthi umbala wekhasimende awukwazi ukushintshwa ngomunye umbala, kodwa ikhasimende linezidingo eziqinile kakhulu embala, ngakho lingakwazi ukudlulisa kuphela inani eliyisisekelo lombala elinikezwa ikhasimende. superimposed ukuthola.
3. Ugibe
Ukucupha kuyadingeka kakhulu kuyo yonke inqubo yokukhiqiza. Ngenxa yokuguquguquka kwepuleti eguquguqukayo, ithambekele ekubhaliseni okungalungile. Inqubo yokubamba isho ukuthi ngisho nokuchezuka okuncane kokubhalisa ngeke kubangele ukumhlophe noma okunye ukunemba. Qondanisa imibala. Inqubo yokubamba ngokuvamile "iyanweba" ukusuka kumbala okhanyayo ukuya kumbala omnyama ngokuqhathaniswa. Isendlalelo sangaphandle siyaphrintwa, futhi usayizi we-overprint ngokuvamile ngu-0.15-0.25mm, onqunywa ikhasimende.
4. Sika, thayipha
Okuqukethwe komkhiqizo kufanele kube izithombe zevekhtha ngangokunokwenzeka. Ngenxa yokuthi okwangempela kwamakhasimende ngezinye izikhathi kufomethi ye-JPG, kuzoba nemiphetho emangelengele ngemva kokuba isithombe sesinwetshiwe, ngakho-ke kuyadingeka ukuba usike. Sebenzisa ithuluzi lepeni kanye nethuluzi lombhalo ukuze usike futhi uthayiphe. Sika ngendlela ongakwazi ngayo efomini lohlaka, ukuze iphethini esikiwe kanye nohlaka lwesampula lokuqala kuhambisane ngangokunokwenzeka. Ngaphandle kwezithombe eziyinkimbinkimbi, wonke amanye amaphethini kufanele asikwe. Lapho uthayipha, naka usayizi wombhalo kanye nefonti efanayo. Lapho wenza umbhalo, guqula umbhalo uwenze umdwebo we-vector ukuze uhambisane nesampula yoqobo.
Uma imivimbo yombhalo kudokhumenti engenayo imincane kakhulu, ngeke iphrintwe ngoba amachashazi asepuletini awakwazi ukuphrintwa ngesikhathi sokuphrinta. Kulokhu, umbhalo udinga ukuba nesibindi. Kufanele futhi kuqashelwe ukuthi ububanzi begebe phakathi kwemivimbo, ngoba uma ibanga phakathi kwamapeni amabili lincane kakhulu, umbhalo uzofiphazwa ngenxa yokusabalala kweyinki ngesikhathi sokunyathelisa, ngakho-ke umbhalo udinga ukukhuliswa ngalesi sikhathi ukwenza igebe phakathi imivimbo ukushintsha Big.
5. Inkinobho ephikisana nokumhlophe
Inkinobho ephikisana nokumhlophe akudingekile ukuthi yenziwe inqobo nje uma ihlangana nomhlophe, kodwa uma umbala oseduze nomhlophe unyatheliswa ngemibala emibili noma ngaphezulu, inkinobho ephikisana nokumhlophe kufanele yenziwe. Ngokuvamile, usayizi wenkinobho ephikisana nokumhlophe ngu-0.07mm, onqunywa ikhasimende. Uma kuyindawo lapho ukuphrinta okweqile kwemibala emibili kunwetshwa khona, gcwalisa umbala ngokuhluka okuncane phakathi kwemibala emibili kanye nombala ophrinte ngokweqile. Inhloso ye-anti-white ukuyeka umbala owodwa. Kodwa-ke, ngenxa yokusetshenziswa kakhulu kwemibala yamabala ekunyatheliseni kwe-flexo, azikho izimo eziningi zokulwa nomhlophe.
