I-RGB yandisa kwaye yakhiwe kukukhanya, i-CMYK iyanciphisa kwaye yakhiwe nge-inki. Ukuguqula phakathi kwayo zizinto ezifunwa ngoyilo olufuna ukuphrinta.
Indlela yokuguqula RGB uye ku-CMYK
- Funda i-R, i-G kunye ne-B njengamaxabiso e-sRGB phakathi kwe-0 ne-255.
- Khangela umbala kwiprofayili ye-Coated FOGRA39, iprofayili ye-ICC emiselweyo yephepha elifakwe ikoti eYurophu.
- Sebenzisa indlela yombala ehambelanayo kunye nokulungelelanisa indawo emnyama, ukuze umhlophe uhlale ungumhlophe wephepha kwaye umnyama ube yeyona nki imnyama kakhulu enokushicilelwa ngumatshini wokushicilela.
- Guqula onke amaxabiso amane abe ngamaphesenti phakathi kwe-0 kunye ne-100.
Umzekelo osebenzayo
Oku kusebenzisa iprofayili esemgangathweni ye-Coated FOGRA39. Iivenkile zokushicilela zisebenzisa iiprofayili zazo ze-ICC kunye nemida yeinki, ngoko ke iiprofayili ze-CMYK ezahlukileyo (umzekelo ezivela kwivenkile yakho yokushicilela) zinika amanani ahlukileyo. Thatha isiphumo njengesalathiso esiqinileyo, hayi njengokwahlukanisa imibala okulungele ukushicilelwa.
RGB kunye ne-CMYK zichazwe
Yintoni i-RGB?
I-RGB ichaza umbala njengeziteshi ezintathu zokukhanya — red, green kunye ne-blue — nganye ukusuka ku-0 ukuya ku-255. Ifana nendlela izikrini ezisebenza ngayo: zonke ezintathu kwi-255 zinika umhlophe, zonke kwi-0 zinika omnyama. I-RGB lulungelelo xa kufuneka ubale nombala, kwaye i-rgba() yongeza ukungabonakali ngaphezu kwayo.
- Isyntax:
- rgb(R, G, B)
- Ububanzi:
- 0–255 per channel
- Ilungele kakhulu:
- ikhowudi, canvas, ukungabonakali nge rgba()
Yintoni i-CMYK?
I-CMYK ngumzekelo we-inki ezine osetyenziswa kuphrinto: cyan, magenta, yellow kunye ne-key (black), nganye njengipesenti ukusuka ku-0 ukuya ku-100. I-inki isusa ukukhanya endaweni yokukukhupha, ngoko ke i-CMYK ibamba imibala embalwa kune-skrini — yiyo loo nto imibala ekhanyayo yesikrini idla ngokubonakala ingacacanga xa iphrintiwe.
- Isyntax:
- cmyk(C%, M%, Y%, K%)
- Ububanzi:
- 0–100% per ink
- Ilungele kakhulu:
- ukuphrinta, ukupakisha, imisebenzi yerhafu-press elungele umsebenzi
