Overprinting kev sib raug zoo:
Overprinting yog hais txog cov txheej txheem luam ntawv ntau xim rau sab saum toj ntawm ib leeg los tsim cov xim tshiab lossis cov nyhuv. Kev sib raug zoo overprinting yuav ua li cas cov xim sib txawv ntawm cov xim sib txawv thaum luam tawm hauv cov khaubncaws sab nraud povtseg. Piv txwv li, cyan, magenta, thiab daj tuaj yeem luam tawm los tsim cov duab puv xim uas siv cov xim rho tawm.
Rotogravure Xim Sequence:
Rotogravure colour sequence yog hais txog qhov kev txiav txim uas cov xim number case luam tawm hauv rotogravure txheej txheem luam ntawv. Nws yog txiav txim los ntawm lub tshuab luam ntawv teeb tsa thiab cov xim uas xav tau. Cov xim sib lawv liag kom ntseeg tau tias cov xim luam tawm ua kom raug thiab tsim cov txiaj ntsig xav tau.
Back Printing thiab Face Printing:
Rov qab luam ntawv thiab lub ntsej muag luam ntawv yog cov txheej txheem hauv rotogravure printing. Rov qab luam ntawv suav nrog kev luam ntawv ntawm sab nraub qaum ntawm lub pob tshab substrate, uas tuaj yeem tsim qhov pom kev tsis zoo. Lub ntsej muag luam ntawv, ntawm qhov tod tes, yuav tsum luam tawm ntawm sab xub ntiag ntawm lub substrate, tsim cov duab loj lossis tsim.
Spot Colours thiab Specialty Inks:
Cov xim xim xa mus rau cov xim sib xyaw ua ntej sib xyaw uas siv los ua kom tiav xim luam tawm rau cov logos, branding, thiab lwm yam tsim qauv. Cov xim no tsis ua tiav los ntawm tus txheej txheem CMYK xim sib xyaw. Cov inks tshwj xeeb, xws li cov xim hlau lossis cov fluorescent inks, yog siv los tsim cov kev pom kev tshwj xeeb uas sawv tawm ntawm cov ntaub ntawv luam tawm.
Hauv cov ntsiab lus, rotogravure luam ntawv ntiav cov xim thawj los tsim ntau yam xim, siv cov ntawv luam tawm kom ua tiav cov kev xav tau, ua raws li cov xim tshwj xeeb, thiab siv cov tswv yim zoo li rov qab thiab lub ntsej muag luam ntawv. Spot xim thiab tshwj xeeb inks muab cov kev xaiv ntxiv rau kev ua tiav cov xim raug thiab txawv ntawm cov txheej txheem luam ntawv.
