Embossing yog cov txheej txheem tsim khoom tom qab luam ntawv tiav, siv cov duab rau cov ntawv luam tawm lossis khoom plig siv cov ntawv ci lossis tsis muaj nws, nyob rau hauv siab thiab kub.

Txiv nyem stamping

Embossing yog siv los ua cov ntawv xa ntawv, daim npav lag luam, cov ntawv lo thiab lwm yam khoom plig. Embossing nrog ntawv ci zoo li qhov zoo tshaj plaws, cov khoom tiav muaj qhov zoo nkauj thiab muaj xim zoo nkauj.

Types of embossing:

• dig muag (dig muag) embossing - extrusion ntawm cov luam tawm hauv qab ntawm cov khoom siv tsis siv cov ntawv ci;
• embossing - compressing khoom ntawm ib qho tshwj xeeb cliché, matrix thiab txiv neej kom muab cov duab convexity; tuaj yeem dig muag lossis foiled;
• kub ntawv nyiaj stamping yog txheej txheem ntawm thermal hloov ntawm cov hmoov metallized los ntawm zaj duab xis mus rau cov khoom siv embossed los ntawm kev siv cliché. Ntau hom ntawv ci yog siv - metallized, textured, pigmented, holographic, thiab lwm yam.

Embossing yog siv dav rau kev ua tiav daim ntawv teev npe npog, nrog rau cov tuav daim npav lag luam, hnab nyiaj thiab lwm yam khoom ua los ntawm cov tawv tawv thiab ntuj tsim.

Clicherau embossing muaj photopolymer thiab hlau (zinc, magnesium, tooj liab, tooj dag, qee zaum hlau):

• photopolymer cliches yog siv rau kev khiav me me (txog 1000 luam tawm) - daim npav lag luam thiab khoom plig. Qhov no yog qhov kev xaiv pheej yig tshaj plaws;
• zinc daim hlau yog siv rau hauv kev tsim khoom txog li 10,000 luam;
• magnesium clichés muaj lawv tus kheej qhov zoo: muaj peev xwm luam tawm ntawm txhua yam khoom, kev tsim khoom sai, sijhawm khiav haujlwm (txog 50,000 luam tawm). Muaj qhov kev xav tob ntawm 0.7-2.5 hli (nyob ntawm cov khoom siv);
• tooj dag cliches yog tsim los ntawm cov tshuab engraving tshwj xeeb los ntawm machining. Qhov zoo - qhov muaj peev xwm muab cov cliche ntau theem ntawm qhov tob, muab cov ntsiab lus embossing qhov siab dua. Lawv yog siv rau ntawm cov ntaub ntawv mos nrog ntau qib embossing. Runtime nyob ntawm phaj thickness (ntau tshaj 50,000 prints).

Photopolymer daim hlau yog photopolymer tso rau ntawm cov hlau substrate thiab tiv thaiv los ntawm ib zaj duab xis los ntawm lub teeb raug.

Hlau daim hlau yog ua nyob rau hauv ob txoj kev - etching (chemical) thiab milling (mechanical). Relief stamping thiab lwm hom kub stamping feem ntau yog ua los ntawm cov khoom siv tshuaj lom neeg.

ntawv nyiaj stamping muaj cov hauv qab no:

1) lavsan puag;

2) cov txheej txheem thermally degradable wax-resin uas tawg thaum cua sov, tso cov ntawv ci hauv qab;

3) xim txheej (lacquer lossis xim txheej) nrog khi;

4)ib txheej nyias ntawm txhuas, tam sim no tsuas yog ntawm holographic thiab metallized foils;

5) nplaum txheej tsim los ua cov txheej txheem rau cov khoom.

Hua rau qhov ntsuas kub uas yuav tsum tau ua, lub cliche tso tawm cov yeeb yuj txheej los ntawm lavsan puag thiab lo rau cov khoom siv embossing. Cov cua kub kub yog xaiv nyob ntawm seb hom ntawv ci, hom cliché, embossed khoom, luam tawm qauv, khoom siv thiab ntau yam.
