Etching yog txheej txheem ntawm kev tsim cov hlau luam tawm phaj siv cov kua qaub. Xim xaum yog siv rau cov ntawv zoo li no thiab tus qauv etched tau sau rau ntawm daim ntawv - qhov no yog li cas engraving tau txais.
Cov Lus Qhia
Kauj ruam 1
Etching lus txhais los ntawm Fabkis txhais tau tias "dej muaj zog". Qhov no yog li cas nitric acid tau hu nyob hauv Nrab Hnub nyoog. Etching yog ib hom engraving, rau uas hlau luam ntawv daim hlau yog tau los ntawm etching nrog muaj zog acids.

Cov txheej txheem ntawm kev tau txais cov ntawv muaj xws li hauv qab no. Cov hlau saum npoo (feem ntau yog tooj liab, zinc lossis steel) yog txheej nrog txheej txheej ntawm cov ciab lossis cov kua roj vanish uas tiv taus qhov kev ua ntawm cov kua qaub. Tom qab ntawd tus kws ua yeeb yam siv cov duab nrog rab koob, tshem cov kua roj vanish. Daim ntawv hlau yog tom qab ntawd muab raus rau hauv da dej ntawm cov kua qaub, uas pib txhuam cov kua roj vanish-dawb saum npoo. Daim ntawv ua tiav tau tawm ntawm da dej, ntxuav thiab tom qab ntawd cov kua roj vanish txheej yog ntxuav tawm los ntawm nws.

Xws engravings tau luam tawm siv ib tug xovxwm. Ua ntej luam ntawv, pleev xim yog thov rau daim ntawv acid-etched, uas ua rau muaj kev poob siab hauv cov hlau. Tom qab ntawv daim ntawv muab tso rau ntawm lub puab thiab muab tso rau hauv xovxwm. Txoj kev no, ntau daim ntawv luam tawm tuaj yeem ua nrog ib tus hlau pwm. Feem ntau, daim ntawv yuav siv tsis tau tsuas yog tom qab luam tawm ob peb puas daim ntawv luam tawm.

Nws tau tsim los siv cov qauv ntawm saum npoo ntawm hlau siv cov kua qaub ua kua dej rov qab rau hauv Nrab Hnub nyoog. Nyob rau hauv no txoj kev, phom, armor, edged riam phom tau dai kom zoo nkauj. Daniel Hopfer yog thawj tus los ua cov ntawv hlau rau luam ntawv ntim nrog cov kua qaub thaum pib ntawm lub xyoo pua 16th. Thaum xub thawj, hlau pwm tau siv rau etching. Tom qab ntawd, tus kws tsim txuj ci Italian pib siv cov phiaj tooj liab.

Hauv lub xyoo pua 17th yav dhau los, tus txiv neej yawg Jacques Callot tau tsim cov ntsia hlau tshwj xeeb rub tawm rab koob. Nws muaj oval-ntu txiav thiab ua rau nws muaj peev xwm los tsim cov duab kos txaij zoo nkauj tiag tiag. Callot kuj tau tsim cov qauv kev kho mob kua qaub ntau theem. Yog hais tias tus kws kos duab xav tau tsim tsuas yog lub teeb, tsis tshua pom lub suab ntawm daim ntawv hlau, ib feem ntawm cov duab kos tau kho sai sai nrog kua qaub, thiab tom qab ntawd ua kom pom tseeb dua kom txuag tau cov kos duab los ntawm ntxiv etching.

Niaj hnub nimno etching masters siv asphalt, bitumen thiab lwm yam khoom siv hloov cov kua roj vanish. Vapors ntawm cov acids muaj zog, nrog rau cov kuab tshuaj, nrog kev pabcuam ntawm cov txheej txheej tiv thaiv txheej txheem yav tas los tau tshem tawm, yog khoom lom. Yog li no, cov txheej txheem kev nyab xeeb zog tau tsim dua tam sim no. Qee cov kws ua yeeb yaj kiab nyiam tsim cov txheej txheej tiv thaiv raws li cov acrylic polymers, thiab cov txheej txheem etching yog nqa tawm siv ferric chloride. Qhov kawg ntawm etching, lub polymer yog ntxuav tawm nrog tov ntawm dej qab zib zoo tib yam.
