Kev Ntsuam Xyuas Ntawm Cov Yam Nyuam Tshaj uas cuam tshuam rau Kev Hloov Cov Tshuaj Ntsuam Txhaj Tshuaj Zej Zos
Peb yog ib lub tuam txhab luam ntawv loj hauv Shenzhen Tuam Tshoj. Peb muaj cov phau ntawv luam tawm, phau ntawv xov xwm luam ntawv, phau ntawv luam ntawv, phau ntawv nyuaj, phau ntawv luam tawm, phau ntawv luam tawm, phau ntawv luam tawm, lub thawv ntim, daim qhia ntawv, txhua yam ntawm PVC, cov ntawv luam tawm, ntawv sau cia, hom tshwj xeeb ntawv xim luam tawm khoom, kev ua si cardand li ntawd.

Vijtsam luam tawm cov ntaub ntawv tias "tag nrho cov khoom tshwj tsis yog cua thiab dej tuaj yeem luam tawm tau." Cov kev sib tw luam tawm yog qhov dav, cov ntawv luam tawm txheej hauv plag yog tuab, qhov layout yog mos, thiab nws tsis yog txwv ntawm qhov loj me, cov khoom thiab cov khoom ntawm cov khoom luam tawm. Nws yog irreplaceable los ntawm lwm txoj kev luam tawm. Nws yog rau cov laj thawj no cov ntaub ntawv tshuaj ntsuam luam tawm ntau los ntawm kev sib ntxub los ntawm kev ntxhib, los ntawm daim ntawv mus rau ntaub hlau thiab iav, uas tuaj yeem hais tias yuav tsum tau tag nrho-encompassing. Nrog rau qhov zoo tshaj plaws ntawm cov duab zoo nkauj thiab cov duab xis, cov neeg cia siab tias qhov screen printing tuaj yeem luam tau cov khoom uas tsuas yog luam tawm ntawm kev luam ntawv. Yog li, ntau tus neeg siv ncaj offset xim sib cais duab rau luam, tab sis qhov kev tshwm sim ntawm luam ntawv yeej tsis muaj kev txom nyem. Lub tswv yim yog tias qhov poob ntawm lub suab nrov yog loj heev thiab xim yog mob hnyav, uas yog los tsim ib lub tshuab moiré uas yooj yim pom. Qhov tshwm sim no tshwm sim vim hais tias lawv tsis meej heev txog cov xwm txheej uas cuam tshuam rau kev hloov ntawm qhov screen printing, thiab yog li tsis tuaj yeem muaj kev txiav txim siab ntau. Rau qhov kawg, daim ntawv no ua rau kev ntsuam xyuas yooj yim ntawm cov xwm txheej cuam tshuam qhov kev hloov ntawm kev tshuaj ntsuam ntawm qhov kev ntsuam xyuas, xws li cov duab kos, tus xov tooj ntawm kab xo, cov khoom siv luam, xaj, lub sij hawm, thiab lwm yam. luam tawm.
1 Txawv ntawm cov qauv ntawm cov qauv hloov
Ua ntej, siv Coreldraw8 ua cov cuab yeej sim rau qhov kev xeem tone - grey scale ntaiv, qhov ntau ntawm cov suab nrov yog 5% -100%. Cov plaub hau kab yog 40lpi, 60lpi, 80lpi, 100lpi, thiab lub kaum ntse ntse sab xis yog 45 degree. Cov ntsiab lus dot yog muab cov dots thiab square dots. Cov ntaub ntawv pov thawj uas siv coated ntawv, ntawv xov, 300 mesh npo, npo luam ntawv number case (fluorescent peach, fluorescent daj, fluorescent xiav), offset number (liab, ntuj xiav, nruab nrab daj, magenta), hlub nrog X-RITE 528 xim reflection density meter thiab kis densitometer ntsuas qhov feem pua poob haujlwm. Sim ua cov ntaub ntawv saum toj no thiab cov seev cev kom tau txais cov ntaub ntawv kev sim (raws li muaj nyob hauv cov rooj nram qab no). Raws li cov ntaub ntawv no, qhov feem pua ntawm cov yeeb yaj kiab (F0) yog npaj rau ntawm txoj kab tav toj, thiab qhov feem pua ntawm cov teeb meem luam tawm (F sau) thiab qhov feem pua ntawm cov dots. Qhov nce siab (ΔF) yog txoj kab xij (qhov sib txawv ntawm qhov feem pua ntawm cov ntawv luam tawm thiab qhov feem pua ntawm cov yeeb yaj duab cov duab), thiab txoj kev hloov pauv yog kos (raws li qhia hauv daim duab 1 txog 5).
Xyaum ua haujlwm 1 Siv tus lej tib yam, tib lub xov tooj ntawm cov kab, tib lub sij hawm, tib lub substrate, thiab luam tawm nrog ntau cov qauv duab (screen printing ntsuab number case, 40 lpi, raug lub sij hawm 40s, coated paper, square dots thiab round dots) .
Los ntawm cov ntaub ntawv ntawm Xyaum 1 (Table 1) thiab qhov hloov curve ntawm cov dot (daim duab 1), nws pom tau tias qhov loj tshaj plaws ntawm cov square teev thiab cov teev teev dot yog 50%, vim hais tias cov square teev nrog rau lwm cov teev rau ntawm 50%. Qhov zoo tshaj yuav yog qhov siab tshaj plaws, vim tias 50% ntawm cov dots txuas nrog ntawm plaub lub ces kaum. Thaum luam ntawv, cov ces kaum yuav ua rau muaj khaub lig ntaws thiab qhov chaw zov me nyuam nce. Lub circumference ntawm cov voj voos yog qhov tsawg tshaj plaws ntawm tag nrho cov dots, thiab nws cov dot yog loj dua. Cov coefficient yog me me, feem ntau ntawm cov xwm txheej hauv nruab nrab, cov dots txuas nrog thaj tsam 70%, tab sis thaum cov dots txuas nrog, qhov zoo tshaj yuav yog qhov loj tshaj, thiab cov dots hauv cheeb tsam uas tsaus nti thaum lub sij hawm luam tawm yuav raug txwv vim ntau dhau number case ntim. Thaum kawg, qhov tsaus nti ntawm daim duab poob mus rau theem nws yuav tsum tau.

Daim Duab 1 Hloov thaj tsam ntawm ntau hom duab sib txawv
2 Cov nyhuv ntawm cov xov tooj ntawm cov kab txuas rau kev hloov ntawm lub network
Xyaum ua piv txwv 2 Printing nrog cov kab mesh sib txawv, tib lub sij hawm, tib lub sijhawm, tib lub sij hawm, tib lub substrate, thiab tib hom (40lpi, 60lpi, 40s, square dots, coated paper, offset red number), Lub cov ntaub ntawv raug ntsuas raws li qhia nyob rau hauv Table 2.
Ntawm cov ntaub ntawv ntawm kev sim 2 (Table 2) thiab qhov kev hloov ntawm qhov hloov dot (daim duab 2), nws tuaj yeem paub tias ntau dua cov npo ntawm cov npo, qhov siab dua tus nqi ntawm qhov kev nce nqi, thiab qhov loj dua rau lub sijhawm nce tus nqi, uas qhia tau hais tias qhov kev luam duab yog guaranteed. Nyob rau hauv rooj plaub qhov sib txawv ntawm cov xim sib cais thiab mesh loj loj dua, ntau dua cov laus ntawm cov duab tiav, thiab tseem muaj qhov cuam tshuam tus qauv rov qab dua, vim hais tias 300 mesh yog siv hauv qhov kev sim no . Nyob rau hauv lub vas, thaum siv 100 lpi kuaj qhov xim sib cais, ib lub tshuab tau tshwm nyob rau ntawm daim phaj ntawv.
