1, rov qab txheej lossis rov qab luam tawm sab nraum qab txheej yog qhov kev tiv thaiv rov qab pov tseg, tom qab rewinding daim ntawv tawm, tom qab rewinding daim ntawv lo rau hauv qab ntawv. Lwm txoj haujlwm yog los ua ntau txheej ntawm cov ntawv lo. Lub Backprinting muaj nuj nqi yog luam tawm cov chaw tsim khoom lag luam cov cim npe lossis cov qauv nyob sab nraum qab ntawm daim ntawv tom qab, uas ua lub luag haujlwm ntawm kev tshaj tawm thiab kev tawm tsam.

2. Cov txheej saum npoo yog siv los hloov cov yam ntxwv saum npoo ntawm cov khoom siv saum npoo av. Piv txwv li, txhim kho cov xim nro, hloov cov txheej tiv thaiv, yog li nws tuaj yeem tiv thaiv cov kua mem kua txiv thiab tiv thaiv cov ntawv luam tawm thiab cov ntawv sau. Cov txheej txheej saum npoo yog siv rau cov ntaub ntawv tsis muaj pa, xws li cov ntawv ci txhuas, aluminium ntawv thiab cov ntaub ntawv zaj duab xis.

3, cov khoom siv saum npoo yog cov khoom siv saum npoo, yog sab xub ntiag kom lees txais cov ntawv luam tawm, sab nraum qab kom lees txais cov nplaum thiab thaum kawg thov ua ntej. Feem ntau hais lus, txhua cov ntaub ntawv hloov tau yooj yim tuaj yeem siv los ua cov ntawv nyeem rau tus kheej, cov khoom siv hlau, ntxiv rau ntawm cov ntawv thov zaum kawg thiab cov txheej txheem luam ntawv. Cov khoom siv saum npoo yuav tsum muaj peev xwm yoog luam thiab luam ntawv, thiab muaj zog txaus kom lees txais kev ua si, xws li kev tuag, slitting, xuas nrig ntaus thiab sau npe.

4, cov nplaum nplaum yog qhov nruab nrab ntawm daim ntawv lo khoom thiab cov ntawv sib khi ua ke, uas ua lub luag haujlwm ntawm kev ua raws. Raws li nws cov yam ntxwv tuaj yeem faib ua kev ruaj khov thiab tshem tau ob hom. Nws los nyob rau hauv ntau yam ntawm cov qauv ua kom haum cov chaw sib txawv thiab cov sijhawm sib txawv. Adhesive yog qhov tseem ceeb tshaj plaws ntawm kev siv tshuab ua kom technology thiab tus yuam sij ntawm daim ntawv lo ntsiab lus siv thev naus laus zis.

5, Tshaj Tawm Txheej (coated nrog silicon txheej) uas yog, nyob rau saum toj no cov roj muaj peev xwm ua tau rau cov roj silicone roj tuaj yeem ua kom tiv thaiv cov nplaum nplaum rau hauv qab ntawv.

6, lub luag haujlwm ntawm cov ntawv hauv qab yog los txais cov ntawv tso tawm, tiv thaiv cov khoom siv saum npoo av, tab sis nws tuaj yeem yog cov khoom siv saum npoo av, tab sis nws tuaj yeem sib npaug ntawm cov khoom siv saum npoo av, lub hom phiaj tseem ceeb ntawm cov khoom hauv qab yog:

(1) txhawm rau tiv thaiv cov khoom siv saum npoo, tiv thaiv kev nkag mus ntawm cov nplaum.

(2) Nce lub abetless ntawm cov ntaub;

(3) nce cov nplaum ntawm cov khoom qub;

(4) Tiv thaiv cov yas yas rau hauv cov yas ua ke los ntawm kev nkag mus rau hauv cov nplaum, ua rau muaj kev sib raug zoo ntawm daim ntawv lo thiab daim ntawv poob.
