Zimaphatikizapo kubaya pulasitiki yosungunuka mu nkhungu kuti apange mawonekedwe ovuta kwambiri molondola komanso osasinthasintha. Njirayi ndi yotsika mtengo komanso yosunthika, ndikupangitsa kuti ikhale njira yabwino yopangira zigawo zazikulu. Mu bukhuli, tidzalowa mozama mu dziko la jekeseni wa pulasitiki, kuphimba chirichonse kuchokera ku mbiri yake ndi mfundo zake zoyambira mpaka mitundu yosiyanasiyana ya nkhungu ndi makina omwe amagwiritsidwa ntchito popanga izi.

Mbiri ya Pulasitiki Jakisoni Woumba

Pakatikati mwa zaka za m'ma 1800, opanga amapanga mipira yoyamba ya mabilidi ya celluloid, yomwe inali chiyambi cha mbiri yakale ya jekeseni wa pulasitiki. John Wesley Hyatt poyamba anavomereza ndondomekoyi mu 1872 ndipo anapanga makina omwe analowetsa celluloid mu nkhungu. Makina oyambirirawa adayala maziko a njira yamakono yopangira jakisoni wapulasitiki.

M'zaka za m'ma 20, kuumba jekeseni wa pulasitiki kunakula kwambiri pamene opanga ambiri adazindikira ubwino wake kuposa njira zina zopangira. M'zaka za m'ma 1950, opanga adayambitsa makina oyamba opangira jekeseni, omwe adatsegula njira yopangira mapulasitiki ambiri. Kuyambira pamenepo, ndondomekoyi yasintha ndi kupita patsogolo kwaukadaulo ndi zida, zomwe zimapangitsa kukhala njira yopangira zida zapulasitiki.

Mfundo Zazikulu Zakuumba jekeseni wa Pulasitiki

Kumangira jekeseni wa pulasitiki ndi njira yovuta yomwe imaphatikizapo zigawo zingapo, kuphatikizapo makina opangira jakisoni, zinthu zapulasitiki, ndi nkhungu. Nazi mfundo zazikuluzikulu za jekeseni wa pulasitiki:
