Hordhac:

Daabacaadda midab-kala-duwan ee midab-kala-duwan, tayada midabka daabacadu waxay ku xiran tahay dhowr arrimood oo kantarool ah, mid ka mid ah kuwaas oo ah midabka daabacaadda.Sidaa darteed, waa muhiimad weyn in la doorto nidaamka midabka saxda ah ee daabacaadda tayada midabka.Habaynta macquulka ah ee isku xigxiga midabka ayaa ka dhigi doonta midabka walaxda daabacan mid aad ugu dhow qoraal-gacmeedka asalka ah.Warqadani waxay si kooban u qeexaysaa saamaynta ay daabacaadu ku leedahay tayada midabka walxaha daabacan.

Daabacaadda isku xigxiga midabka

Daabacaadda isku xigxiga midabka waxa loola jeedaa nidaamka daabacaadda monochrome ee daabacaadda midabada badan.Tusaale ahaan, daabacaha afar-midab ah ama daabacaha laba-midab ah ayaa saameeya isku xigxiga midabka.Guud ahaan marka loo eego, waa isticmaalka habaynta midabka kala duwan ee daabacaadda, natiijooyinka daabacadu way ka duwan yihiin, mararka qaarkood daabacaadda midabka ayaa go'aamisa quruxda arrin daabacan iyo in kale.

01 Xidhiidhka ka dhexeeya madbacadaha iyo isku xigxiga midabka Lambarka midabka madbacadda waa in la tixgeliyaa marka la dooranayo taxanaha midabka daabacaadda.Mashiinnada daabacaadda kala duwan waa in loo isticmaalaa in lagu daabaco midabyo kala duwan sababtoo ah dabeecadooda shaqo ee kala duwan.

Mashiinka monochrome

Mashiinka monochrome waxaa iska leh daabacaadda qalalan ee saxaafadda qoyan.Waraaqda u dhaxaysa midabka daabacadu way fududahay in la dheereeyo oo la beddelo, markaa daabacaadda guud ee ugu horreysa ee saxnaanta shuruudaha daabacaadda ee jaalaha iyo madow, ilaa warqaddu u egtahay mid xasilloon ka dibna daabacaadda midabka la daabacayo.Marka midabka ugu horreeya ee daabacaadda uu qallalo, mugga wareejinta khadku wuxuu ka sarreeyaa 80%.Si loo yareeyo farqiga midabka ee daabacaadda xad-dhaafka ah, dhig midabka muhiimka ah ee sawirka, marka hore waa in la daabacaa codka ugu weyn.

Mashiin laba midab leh

Midabada 1-2 iyo 3-4 ee mashiinka laba-midabka leh ayaa iska leh daabacaadda qalalan ee saxaafadda qoyan, halka midabada labaad iyo saddexaad ay ka tirsan yihiin daabacaadda qalalan ee saxaafadda qoyan.Midabka soo socda ayaa guud ahaan loo isticmaalaa daabacaadda: 1-2 midab daabacaadda magenta - cyan ama cyan - magenta;3-4 midab daabacaadda madow-jaalle ama huruud-madow.

Mashiinka midabka badan

Mashiinka midab-kala-duwan ee daabacaadda qoyan ee saxaafadda qoyan, taas oo u baahan in khad kastaa uu ahaado mid sax ah ee daabacaadda degdegga ah, iyo xiisadda khad daabacan, ma noqon karto khad kale oo ka soo baxa dusha daabacaadda "ka qaad".Xaaladda daabacaadda dhabta ah, midabka koowaad ee daabacaadda midabka labaad, midabka saddexaad iyo midabka afraad, qayb ka mid ah khadadka ayaa lagu dhegay bustaha, sidaas darteed bustaha midabka afaraad ayaa si cad u soo bandhigaya afar- sawirka midabka.Khadka midabka 3aad wuu ka yar yahay, kaliya midabka 4aad ayaa 100% la hayaa.

02 Xiriirka ka dhexeeya sifooyinka khad iyo isku xigxiga midabka

Tilmaamaha khad iyo isku xigxiga midabka

Xulashada isku xigxiga midabka (gaar ahaan daabacaadda midabada badan), si loo tixgeliyo sifooyinka khad: viscosity khad, dhumucda filimka khad, daahfurnaanta, qalajinta, iwm.

Viscosity

Viscosity-ka khadku wuxuu door muuqda ka ciyaara daabacaadda xad-dhaafka ah.In doorashada waa in ay ahaataa dareere yar, viscosity ee khad weyn ee xagga hore.Haddii aan la tixgalinayn viscosity-ka khadku waxay dhici doontaa ifafaale "ka-soo-noqoshada", waxay u horseedi doontaa isbeddelka midabka, taasoo keenaysa sawir mugdi ah, midab cawl, iftiin la'aan.

Guud ahaan cabbirka khad afar-midab ah waa madow > cagaar > magenta > huruud ah, markaa mishiinka guud ee afarta midab leh ayaa si aad ah u isticmaala "cyan madow - magenta - huruud" midabaynta daabacaadda, si loo kordhiyo xawaaraha daabacaadda.

Dhumucda filimka khad

Dhumucda filimka khadku waa qodobka muhiimka ah si loo gaaro hoos u dhigista ugu wanaagsan ee heerarka midabka daabacaadda.Filimka khadku aad buu u dhuuban yahay, khadku si siman uma dabooli karo warqadda, daabacaadda dhalaalka shaashadda, midabku wuxuu u janjeeraa inuu noqdo mid qoto dheer, dawakhsan;Filimka khadku aad buu u qaro weyn yahay, way fududahay in uu keeno kororka dhibcaha mesh, nooca dhejiska, lakabka niyad jab.

Guud ahaan, xulashada kordhinta dhumucda filimka khad ee taxanaha midabka daabacaadda, kuwaas oo ah "madow - cagaar - magenta - jaalle" si loo daabaco, saameynta daabacaadda ayaa ka fiican.

Hufnaan

Daah-furnaanta khadku waxay ku xidhan tahay kala duwanaanshaha tusaha refractive ee midabada iyo xidhayaasha.Diaphaneity of khad ka dib markii overprinting midabka saamaynta weyn, sida ka dib markii overprinting midabka ma fududa si ay u muujiyaan midabka saxda ah;Khad badan oo daah-furnaan sare leh - midab-daabacaadda, marka hore daabacaadda iftiinka midabka qalinka iyada oo loo marayo khad daabacaadda dambe, gaadhitaanka saamaynta isku dhafka midabka wanaagsan.Sidaa darteed, daahfurnaanta liidata ee khad marka hore, hufnaanta sare ee khad daabacaadda ka dib.

Qalalan

Laga soo bilaabo qalin qalajinta si loo tixgeliyo, si loo sameeyo midabka qalin daabacaadda mid dhalaalaya, saameyn daabacan oo wanaagsan, wuxuu daabici karaa qalin daabacaadda tartiib tartiib ah marka hore, daabacaadda xawaaraha qalajinta qalinka dambe.

03 Xiriirka ka dhexeeya guryaha waraaqaha iyo isku xigxiga midabka

Guryaha warqaddu waxay si toos ah u saameeyaan tayada walxaha daabacan.Daabacaadda ka hor, warqaddu waxay inta badan tixgelisaa jilicsanaanta, cidhiidhiga, qallafsanaanta, iwm.

Jilicsanaan

Waraaqo siman oo sarreeya, daabacaaddu waxay si dhow ula xiriirtaa buste, waxaa lagu daabici karaa midab isku mid ah, sawir cad oo alaabta ah.Iyo simanaanta hoose ee warqadda, daabacaadda sababtoo ah dusha aan sinnayn ee warqadda, wareejinta khad ayaa saameyn doonta, taasoo keentay daabacaadda dhumucda filimka khad, qaybta sawirka ee sinnaanta khad ayaa hoos u dhacday.Sidaa darteed, marka jilicsanaanta warqaddu hooseyso, midabka granule pigment wuxuu ku yaalaa midabka kowaad.

Cidhiidhi

Cidhiidhiga warqadda iyo jilicsanaanta warqadda ayaa si dhow ula xidhiidha.Guud ahaan, jilicsanaanta warqadda oo leh kororka cidhiidhiga warqadda iyo hagaajinta.Cidhiidhi sare, jilicsanaan wanaagsan oo warqad ka hor daabacaadda midab madow, ka dib daabacaadda midabka iftiinka;Taas bedelkeeda, midabka ugu horreeya ee daabacaadda iftiinka (jaalle), ka dib midabka mugdiga ah, tani waxay inta badan sabab u tahay khad huruud ah oo dabooli kara dhogorta waraaqaha iyo budada iyo cilladaha kale ee waraaqaha.

Qallafsanaan

Inta lagu jiro habka daabacaadda, warqaddu waa ay noqon doontaa mid qallafsan oo lagu kordhin doonaa ilaa xad iyada oo loo marayo rullaluistemadka iyo saamaynta dareeraha socda, taas oo ku xidhan tahay in ay saameynayso saxnaanta daabacaadda daabacaadda.Sidaa darteed, waa in marka hore daabacdaa aagga nooca midab yar ama nooca mugdiga ah, ka dibna daabac aagga nooca midabka weyn ama nooca midabka iftiinka.

04 Midabka midabka gaarka ah ee daabacaadda gaarka ah

Daabacaadda iyo soo saarista shaqooyinka asalka ah ee gaarka ah, daabacaadda midabka midabaynta ayaa door aad u jilicsan ka ciyaara, taas oo aan samayn karin oo kaliya in daabacaadda ay ku dhowdahay ama soo celiso asalka, laakiin sidoo kale waxay dib u soo saartaa soo jiidashada farshaxanka ee asalka ah.

Midabka asalka ah

Qoraal-gacmeedka asalka ah ayaa saldhig u ah samaynta saxan-samaynta iyo daabacaadda labadaba.Qoraal gacmeedka midabka guud wuxuu leeyahay codka ugu weyn iyo dhawaaq hoose.Midabada ugu muhiimsan, waxaa jira midabyo qabow (cagaaran, buluug, guduud, iwm.) iyo midabyo diiran (jaalle, oranji, casaan, iwm.).Xulashada nidaamka midabka, waa inay raacaan mabda'a aasaasiga ah iyo kan sare.Sidaa darteed, qaabka isku xigxiga midabka, oo leh midabyo diirran oo inta badan daabacan madow, cagaar, casaan, jaalle;Si loo qaboojiyo midabka - daabacaadda ku salaysan casaanka, ka dib daabacaadda cagaarka.Haddii codka ugu weyn ee rinjiyeynta muuqaalku uu yahay midab qabow, isku xigxiga midabka waa in lagu dhejiyaa saxanka cagaaran mar dambe ama daabacaadda ugu dambeysa;Iyo codka ugu weyn ee rinjiyeynta shaxanka ee midabka diirran, si magenta, waa in lagu dhejiyaa nooca magenta ka dib ama daabacaadda ugu dambeysa, si codka ugu weyn uu u noqon karo agagaarka sawirka muujinaya mawduuca.Sidoo kale, codka ugu muhiimsan ee rinjiyeynta dhaqameed ee Shiinaha ee madow, madow waa in lagu dhejiyaa daabacaadda dambe ama dambe.
