Ithemba lophuhliso lweshishini leetreyi zephepha libanzi,
kunye neetreyi zephepha ziyasetyenziswa nakwimizi-mveliso emininzi.
Izizathu zishwankathelwe ngolu hlobo lulandelayo:
(1) Uphuhliso olukhawulezayo lwezoqoqosho lubonelela ngamathuba ophuhliso kushishino lweetreyi zokupakisha.
(2) Ukuphuculwa okuqhubekayo kwetekhnoloji yokuprinta itreyi yephepha nayo ifuna
ukuphucula okuhambelanayo kwinqanaba lobugcisa bokupakisha.
(3) Ngokuphuculwa kwemigangatho yokuphila yabantu kunye nokwandiswa kolwazi lwabo ngobuhle,
Abantu bahlawula ngakumbi nangakumbi kupakisho yetreyi yamaphepha.
(4) Ukonyusa ixabiso kunye nexabiso elongezelelweyo kwiimveliso zabo,
abathengi bafuna ukuphuculwa kwenqanaba lokupakishwa kwepallet yephepha.
(5) Iinkampani eziluncedo ezineempawu, ezinje ngecuba, utywala, ukutya, amayeza,
izinto ezincinci zasendlini, izinto zokuthambisa, njl.
eqhuba ukukhula komzi mveliso wetreyi yamaphepha.
