Hauv -pwm daim ntawv lo luam ntawv tuaj yeem siv ntau yam txheej txheem, suav nrog offset, flexographic, letterpress, thiab gravure printing, nrog offset thiab flexographic luam ntawv tam sim no feem ntau.
Offset Printing: Cov txiaj ntsig zoo yog qhov tseem ceeb hauv kev luam ntawv zoo, tab sis kab thiab cov khoom luam tawm zoo thiab saturation tsis zoo li lwm txoj kev luam ntawv. Haum rau me me -batch ntawv luam ntawv, nrog lub sij hawm luv luv thiab yooj yim.
Gravure Printing: Cov khoom luam tawm zoo thiab cov xim saturation yog qhov zoo tshaj rau kev luam ntawv offset, tab sis nws tsis haum rau kev luam ntawv me me thiab cov cim lag luam nrog cov nplua nuj tonal variations. Kev tswj xim sib txawv yog qhov yooj yim, tab sis phaj- ua cov nqi siab thiab cov sij hawm ua cov hmoov lead yog qhov ntev, ua rau nws haum rau ntev - khiav hauv - pwm luam ntawv.
Letterpress Printing: Tsim nyog rau kev luam ntawv khoom thiab kab lag luam, tab sis cov txiaj ntsig ntawm kev luam ntawv me me tsis zoo tagnrho. Kev tswj xim sib txawv yog ib qho yooj yim, tab sis tus cwj mem streaks yuav tshwm sim. Tus nqi qis dua gravure thiab flexographic luam ntawv.
Flexographic Printing: Nws lub ntsiab kom zoo dua yog tias luam ntawv thiab xa ntawv - ua tiav tuaj yeem ua tiav hauv ib qho, ua tiav inline ntawm kev luam ntawv thiab xa tawm - ua tiav. Dot luam ntawv zoo tau txhim kho zoo heev, thiab kev siv ib puag ncig tus phooj ywg UV inks tau dhau los ua tus qauv hauv -pwm daim ntawv lo luam ntawv.
