Thaum lub sij hawm kub stamping txheej txheem, daim duab tau pom muaj kev xav thiab kev tsaus muag, thiab kub kub lub thawv kub hnyav heev dhau lawm, thiab daim ntawv tshauv kub kub coked. Yog tias kub kub ntawm cov ntawv phaj siab yog siab dhau heev lawm, daim ntawv nplaum tshauv kub tshaj yuav dhau qhov kev txwv uas tuaj yeem tiv thaiv tau. Nyob rau lub sij hawm no, ntawv xov xwm kub kub yuav kis tau mus rau lub plawv, ua rau muaj halo thiab tsaus muag, uas yuav tsum tau ua raws li cov yam ntxwv ntawm daim ntawv tshauv kub. Qhov ntsuas kub yog kho kom haum. Rau qhov coking of stamping paper, qhov tseem ceeb yog vim tias kev kub nyhiab yog tso tseg ntev ntev, kom qee qhov chaw ntawm daim ntawv stamping yog nyob rau hauv kev sib txuas nrog lub tshuab electrothermal siab kub luam ntawv ntev, thiab qhov phenomenon ntawm rhuab coking tshwm sim, thiab cov duab yuav faint tom qab kub stamping. Yog li, yog tias qhov ntsuas kub yuav tsum tau qis dua thaum cov txheej txheem ntau lawm, los sis yog tias daim ntawv tshauv kub kub tawm, daim ntawv tuab tuaj yeem muab tso rau hauv phaj siab dua cov ntawv xov xwm kom tshem tawm cov ntawv xov kub ntawm cov ntawv phaj.
