Chero bedzi iyo R+G+B mavara matatu achibonderana zvakaenzanirana, anopfuura makumi emamiriyoni emavara anogona kugadzirwa.Sei mutema?Dema rinogona kugadzirwa kana reshiyo kuRGB yakaenzana, asi zvinotora ingi nhatu kuburitsa rumwe ruvara, izvo zvisingagoneke kubva kune yehupfumi maonero.Kutaura zvazviri, dema rinoshandiswa zvakanyanya mukugadzirisa maitiro, izvo chaizvoizvo nei kudhinda-mavara mana kunoshandiswa.Pane imwezve pfungwa: kana dema rakagadzirwa neRGB richifananidzwa nedema rakanyatso kusanganiswa neingi, yekutanga ine pfungwa yekusaita, nepo iyo yekupedzisira inonzwa kurema.
1. Nemutemo wemavara mana, zviri nyore zvikuru kuti munhu wose agamuchire.Iyo yakaenzana nemafirimu mana panguva yekubuda, uye zvakare yakaenzana nematanho mana e cyan, magenta, yero, uye dema (C, M, Y, K) mumatanho muPHOTOSHOP.Iko kugadziridzwa kwechiteshi kana isu tichigadzira chifananidzo ichokwadi shanduko kufirimu.
2. Meshes, madots nemakona, mambure akati sandara nemambure anorembera.Mesh: paskweya inch, huwandu hwemadots akaiswa, 175 mesh yezvakajairwa zvakadhindwa, uye 60 mesh kusvika 100 mesh yepepanhau, zvichienderana nemhando yebepa.Kudhinda kwakakosha kune meshes akakosha, zvichienderana nekugadzirwa.
1. Mamiriro uye kururama kwemufananidzo
Kudhinda kwemazuva ano kweoffset kunoshandisa kudhinda kweoffset (kuwedzeredza mavara mana), ndiko kuti, mufananidzo weruvara wakakamurwa kuva mavara mana: cyan (C), chigadzirwa (M), yeyero (Y), nhema (B) ine mavara mana firimu, wobva waprinda The PS plate inodhindwa kana nemuchina weoffset, uyezve iri chigadzirwa chakadhindwa neruvara.
Kudhinda mifananidzo kwakasiyana neyakajairwa komputa inoratidza mifananidzo.Iwo mapikicha anofanira kunge ari muCMYK modhi panzvimbo yeRGB modhi kana mamwe modhi.Kana uchiburitsa, mufananidzo unoshandurwa kuita dots, inova ndiyo chaiyo: dpi.Iyo yetioretical yakaderera chaiyo yemifananidzo yekudhinda inofanirwa kusvika 300dpi/pixel/inch, uye mifananidzo yakanaka yaunowanzo kuona pakombuta inowanzonzwa yakanaka kwazvo pamonitor.Muchokwadi, mazhinji acho 72dpi RGB modhi mifananidzo, uye mazhinji acho haagone kushandiswa kudhinda.Mifananidzo yakashandiswa haifanirwe kuratidzwa seyakajairwa.Usafunge kuti mapikicha anogona kushandiswa kudhinda nekuti anoyevedza kuburikidza neacdsee kana imwe software, uye anoyevedza mushure mekukwidziridzwa.Iwo anofanirwa kuvhurwa muphotoshop, uye saizi yemufananidzo inoshandiswa kuratidza huchokwadi.Kururama.Semuenzaniso: mufananidzo une sarudzo ye 600 * 600dpi / pixel / inch, ipapo hukuru hwayo huripo hunogona kuwedzerwa kudarika kaviri uye hunoshandiswa pasina dambudziko.Kana sarudzo iri 300 * 300dpi, saka inogona kuderedzwa chete kana saizi yepakutanga haigone kuwedzera.Kana iyo sarudzo yepikicha iri 72 * 72dpi / pixel / inch, saka saizi yayo inofanira kuderedzwa (iyo dpi yakarurama ichave yakakura), kusvikira sarudzo yava 300 * 300dpi, inogona kushandiswa.(Paunenge uchishandisa basa iri, isa chinhu "Redefine Pixel" mune saizi yemufananidzo muPhotoshop kune imwe.)
Mafomati emifananidzo akajairika ndeaya: TIF, JPG, PCD, PSD, PCX, EPS, GIF, BMP, nezvimwewo. Pakunyora, TIF ruvara, dema nechena bitmap, EPS vector kana JPG
2. Ruvara rwemufananidzo
Nezve mamwe mazwi ehunyanzvi akadai sekuwandisa, kudhinda, kuburitsa kunze, uye ruvara rwemavara mukudhinda, unogona kutarisa kune mamwe ane hukama kudhinda.Heano mamwe epfungwa dzakajairika dzinofanirwa kutariswa.
1, hombe kunze
Pane mutsara wemavara ebhuruu akatsikirirwa payero yepasi ndiro, saka payero ndiro yefirimu, nzvimbo yemavara ebhuruu inofanira kunge isina chinhu.Izvo zvakapesana ndezvechokwadi zvakare kune yebhuruu vhezheni, zvikasadaro chinhu chebhuruu chichadhindwa zvakananga pane yeyero, ruvara ruchachinja, uye yepakutanga yebhuruu hunhu huchave hwakasvibira.
2. Overprint
Pane mutsara wemavara matema akatsikirirwa pane imwe ndiro tsvuku, ipapo nzvimbo yemavara madema pahwendefa tsvuku yefirimu haifaniri kuvharwa kunze.Nekuti dema rinogona kubata chero ruvara, kana iyo dema yemukati yakavharwa, kunyanya mamwe manyoro madiki, kakanganiso kadiki pakudhinda kuchaita kuti mupendero muchena uburitswe, uye mutema nemuchena musiyano wakakura, zviri nyore kuona.
3. Mavara mana-ruvara dema
Iri zvakare idambudziko rinowanzoitika.Usati waburitsa, unofanira kutarisa kuti mavara matema ari mufaira rekudhindisa, kunyanya kadikidiki, ari pandiro nhema chete, uye haafanire kuoneka pane mamwe mahwendefa ane mavara matatu.Kana zvikaonekwa, kunaka kwechigadzirwa chakadhindwa kuchaderedzwa.Kana iyo RGB mifananidzo ichishandurwa kuita CMYK mifananidzo, iyo nhema mavara anozonyatsoita mana-mavara matema.Kunze kwekunge zvatsanangurwa neimwe nzira, inofanirwa kugadziriswa firimu risati raburitswa.
4. Mufananidzo uri muRGB mode
Kana uchiburitsa mifananidzo muRGB modhi, iyo RIP system inowanzo shandura otomatiki kuita CMYK modhi yekubuda.Zvisinei, hutano hwemavara huchaderedzwa zvikuru, uye chigadzirwa chakadhindwa chichava nemuvara wakajeka, kwete wakajeka, uye mhedzisiro yacho yakaipa kwazvo.Mufananidzo wacho unoshandurwa zvakanyanya kuita CMYK modhi muphotoshop.Kana chiri chinyorwa chakaongororwa, chinofanira kuenda kuburikidza nekugadzirisa kwemavara mufananidzo usati washandiswa.
