Ukulandelelana kombala woshicilelo kubhekiselele kulandelelwano apho ipleyiti yoshicilelo yombala ngamnye ibhalwe ngaphezulu ngombala omnye njengeyunithi yoshicilelo olunemibala emininzi.
Umzekelo: umatshini wokushicilela onemibala emine okanye umatshini wokushicilela onemibala emibini uchatshazelwa kulandelelwano lombala. Ngokwemigaqo ye-layman, kuthetha ukusebenzisa ulungelelwaniso oluhlukeneyo lombala ekushicileleni, kwaye iziphumo eziprintiweyo eziphumayo zahlukile. Ngamanye amaxesha ukulandelelana kombala wokushicilela kugqiba ubuhle bento eshicilelweyo.
01 Izizathu zokuba kutheni ukuprintwa kombala wolandelelwano kufuneka kucwangciswe
Kukho izizathu ezithathu eziphambili zokuba kutheni ukulandelelana kombala kufuneka kucwangciswe:
Esona sizathu sisisiseko ukungafihli okungaphelelanga kwe-inki yokushicilela ngokwayo, oko kukuthi, amandla okugquma e-inki ngokwayo. I-inki eprintiweyo kamva inempembelelo ethile yokugquma kumaleko we-inki aprintwe kuqala, okukhokelela kumbala wento eprintiweyo esoloko ijolise kumaleko amva. Umbala, okanye umxube wemibala ogxininisa umbala wangemuva kunye nombala wangaphambili.
02 Izinto ezichaphazela ukulandelelana kombala woshicilelo
1. Qwalasela ukungafihli kwe-inki
Ukucaca kwe-inki kuhambelana namandla okufihla ii-pigments kwi-inki. Okubizwa ngokuba yi-inki yokufihla amandla ibhekiselele kwisakhono sokugquma se-inki yokugquma kwi-inki engaphantsi. Ukuba isigqubuthelo sombane sithe sibi, ukucaca kwe-inki komelela; ukuba amandla okugquma womelele, ukungafihli kwe-inki kuya kuba kubi. Ukuthetha jikelele,ii-inki ezinamandla okufihla okulambathayo okanye ukungafihli okulomeleleyo kufuneka ziprintwe ngasemva, ukwenzela ukuba ukukhazimla kwe-inki yoshicilelo yangaphambili ayiyi kugqunywa ukuququzelela ukuveliswa kombala.Ubudlelwane phakathi kokungafihli kwe-inki yile: Y>M>C>BK.
