1, txheej txheej rov qab los yog rov qab luam ntawv rov qab txheej yog txheej tiv thaiv sab nraub qaum ntawm daim ntawv hauv qab kom tsis txhob muaj cov khib nyiab pov tseg, tom qab rov ua daim ntawv lo nyob ib ncig ntawm daim ntawv nplaum rau hauv qab daim ntawv. Lwm txoj haujlwm yog ua kom ntau txheej ntawm daim ntawv lo. Lub backprinting muaj nuj nqi yog luam tawm cov chaw tsim khoom lag luam sau npe lossis cov qauv nyob rau sab nraum qab ntawm daim ntawv thaub qab, uas ua lub luag haujlwm ntawm kev tshaj tawm thiab kev tiv thaiv cuav.

2. Cov txheej txheej saum npoo yog siv los hloov cov yam ntxwv ntawm cov khoom nto. 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 tsuas yog siv rau cov ntaub ntawv tsis nqus, xws li txhuas ntawv ci, aluminized ntawv thiab ntau yam ntaub ntawv zaj duab xis.

3, cov khoom siv saum npoo yog cov khoom siv saum npoo, yog pem hauv ntej lees txais cov ntawv luam tawm, sab nraub qaum lees txais cov nplaum thiab thaum kawg siv rau cov khoom yuav tsum tau pasted. Feem ntau hais lus, tag nrho cov ntaub ntawv hloov tau yooj yim tuaj yeem siv los ua cov ntaub nplaum rau tus kheej, xws li cov ntawv siv feem ntau, zaj duab xis, cov ntawv ci sib xyaw, txhua yam ntawm textiles, nyias cov ntawv hlau thiab roj hmab, thiab lwm yam. Hom nto nyob ntawm daim ntawv thov zaum kawg thiab txheej txheem luam ntawv. Cov khoom siv saum npoo yuav tsum tuaj yeem hloov kho rau kev luam ntawv thiab luam ntawv, muaj cov inking zoo, thiab muaj lub zog txaus los lees txais ntau yam kev ua, xws li kev txiav tuag, pov tseg, slitting, xuas nrig ntaus thiab sau ntawv.

4, nplaum nplaum yog qhov nruab nrab ntawm cov khoom siv daim ntawv lo thiab cov khoom sib txuas, uas ua lub luag haujlwm ntawm kev sib txuas. Raws li nws cov yam ntxwv muaj peev xwm muab faib ua mus tas li thiab tshem tau ob yam. Nws los nyob rau hauv ntau yam formulations kom haum rau txawv qhov chaw thiab ntau zaus. Adhesive yog qhov tseem ceeb tshaj plaws ntawm cov khoom siv tus kheej nplaum thiab qhov tseem ceeb ntawm daim ntawv thov technology.

5, tso tawm txheej (coated nrog silicon txheej) uas yog, nyob rau saum npoo ntawm daim ntawv hauv qab coated nrog silicone roj txheej, coated nrog silicone roj yuav ua rau hauv qab daim ntawv mus rau hauv ib tug heev tsawg nto nro, heev du nto, lub luag hauj lwm yog mus rau lub hauv qab daim ntawv. tiv thaiv cov nplaum nplaum ntawm daim ntawv hauv qab.

6, lub luag haujlwm ntawm daim ntawv hauv qab yog lees txais cov txheej txheem tso tawm, tiv thaiv cov nplaum rau sab nraum qab ntawm cov khoom siv saum npoo, txhawb cov khoom siv saum npoo, kom nws tuaj yeem tuag-txiav, pov tseg pov tseg thiab daim ntawv lo rau ntawm lub tshuab labeling. 7, txheej hauv qab yog tib yam li txheej txheej, tab sis yog coated rau sab nraum qab ntawm cov khoom nto, lub hom phiaj tseem ceeb ntawm txheej hauv qab yog:

(1) los tiv thaiv cov khoom nto, tiv thaiv kev nkag mus ntawm cov nplaum.

(2) Ua kom cov lightlessness ntawm cov ntaub;

(3) Ua kom cov nplaum nplaum ntawm tib yam khoom nto;

(4) Tiv thaiv cov yas yas hauv cov khoom siv yas los ntawm kev nkag mus rau hauv cov nplaum, cuam tshuam rau kev ua haujlwm ntawm cov nplaum, ua rau txo qis ntawm cov nplaum nplaum ntawm daim ntawv lo thiab daim ntawv lo poob.
