In gravure printing, the entire surface of the printing plate is covered with ink, and then a special scraping mechanism is used to remove the ink from the blank parts so that the ink only remains in the cells of the graphics and text parts, and then under greater pressure , transfer the ink to the surface of the substrate to obtain printed matter. Gravura printing est recta printing. Et picture et textus parte ex printing laminam concavum est, et in gradu ex tristitia variatur cum profundum imaginis. Blank pars printing laminam convexa et eodem plano.
Gravura printing, referred to as gravari excudendi, est unus de quatuor major printing modos. Gravura excudendi est recta printing modum, quod recta imprints in atramentum continebat in cisternam veterem gravatur onto subiectum. Umbrae typis imaginem determinantur magnitudine et profundum puteos. Si cisternamenta altius, tunc continet magis atramento et atramento iacuit super subiecto postquam embossing densior; Sed si cisternamenta leuis, quod minus atramento et atramento iacuit super subiecto post in subiecto, cum embossing erit densior. Sicut tenuior. In printing laminam de gravus excudendi composito ex puteis correspondentes ad originale imagines et textus et superficies printing laminam. Per excudendi, atramento repleti in cisternam veterem et atramento super superficiem printing laminam est radi cum a ramis. Est quaedam pressura contactus inter printing laminam et subiectum, et atramento in cisternam transfertur ad subiectum ad completum printing. As a type of printing process, gravure printing has the advantages of thick ink layer, bright colors, high saturation, high printing plate durability, stable printing quality, and fast printing speed in the fields of printing, packaging and graphic publishing. occupare est maxime momenti situ.
Type excudendi
Genera Gravura excudendi dividitur in duas genera secundum laminam faciens modum: sculptura gravatur et etching gravatur.
Sculptura gravure
Sculpturing gravure est utor sculptura ferro ad directe carpet cisternames correspondentes ad originale graphics et textus in superficiem de printing laminam cylindri. Secundum ad imperium modum sculptile ferro, potest dividi in manual sculptura intaglio, mechanica sculptura intaglio et electronic sculptura gravatur.
SIMECED Gravure
Et Sheadched gravure laminam factum est per Etching atramento cisternamenta in superficiem de printing laminam cylindri usura eget etching secundum originali image et illud. Secundum diversas modos convertendi originale imagines et illud, etching gravus potest dividitur in Etching gravure, photogravure et dot gravure.
Sheffed gravure laminis fiunt usura a Platemaking modum, quae combines engraving et etching. Hoc est figura originalis image et illud est primum sculpsit per manum, et tunc in intaglio factum est per Etching.
Photogravure est late usus et est maxime communiter usus excudendi laminam in gravus printing. Est maxime usus ad printing pictura laminis, etc.
Dot gravure est maxime propter packaging, ornamentum printing et aedificationem materiae printing.
Excudendi atramento
Gravure atramento composito ex solidum resinae, volatile solvents, pigmenta, fillers et additives. Non continet vegetabilis oleum, et siccatio methodus plerumque volatile. Gravura atramento dividitur in tres genera umbra gravatus atramento; plastic gravis atramento; Vocatus-solutum gravus atramento. Quod munera solvents in atramento includit: Dissolving vel disperso omnem solidum components in atramento; moistening superficies typis substrati; adjusting in siccitate celeritas atramento; Adjusting consistency in atramento ad idoneam ad inking requisitis printing laminam.
Typis materiales
Gravure printing potest esse in amplis materiae, sed est communiter ad print altus-finem charta et plastic films.
Excudendi machina
A gravus excudendi apparatus plerumque consistit ex octo major partes, comprehendo unwinding pars, dux cylindro, pressura cylindro, printing cylindro, inking parte, medicus ferrum, dryer, et curvis, medicus, dryer, et curva. Quidam gravi excudendi machinis etiam includit potestas ratio et calibration ratio. et electrica systems.
Gravure Printing Processus
Ob altum gradum automation of printing apparatus et bonum laminam faciens qualis, processus operationem de gravus excudendi est simplicior et facilius ad dominum quam offset printing. Processus fluxus est ut sequitur:
Pre-Press Praeparatio → Publishing → adjusting praecepta → formalis printing → Post-press processus processus
Commoda et incommoda
Commoda: Ink expressivess est de XC%, cum dives voce. Colo colui cultum reproduction est fortis. Et layout est durabile. In printing quantitas ingens. Et range of chartam usus est lata et materiae praeter charta potest etiam typis.
Incommoda, laminam faciens feodo pretiosa, printing feodo et pretiosa, laminam faciens opus turpis, et non idonea parum prints.
Gravure printing application range
Culpa gravus excudendi, propter eius exquisita lineae et difficultas in counterfeing, adhibetur ad procer securitates, ut banknotes, stocks, donum testimonia, notat et printing, paucis sumptus est ad generalem printing. Gravura quamvis laminam faciens processus magis complicated et pretium est pretiosa, non idoneam excudendi parvae quantitates prints. Est plerumque usus est in magna quantitates typis materia, ut coloris Magazines et currently popularibus aedificium materiae printing, etc. Omnes maxime idoneam. Quia Gravura excudendi utitur summus celeritas gyratorius apparatus, non solum ieiunium sed etiam atramento film typis est multo crassior quam quod letterpress printing vel offset excudendi.
