Rotogravure printing hi eng nge ni ?

Gravure printing chu printing plate chung zawng zawng chu ink-a khuh vek a ni a, chutah chuan special scraping mechanism hmangin ink blank part atanga ink chu lakchhuah a ni a, chutiang chuan ink chu ink graphic part-a mesh cavities-ah chauh a awm ang a, chutah chuan pressure nasa zawka action hnuaiah chuan ink chu substrate chung lamah transfer a ni ang a, chu chuan printed matter chu a hmu ang. Gravure printing hi direct printing a ni. Printing plate graphic part chu concave a ni a, image level nena concavity degree chu shade hrang hrang a nei a, printing plate blank part chu a sang a, cylinder plane khatah a awm bawk.

Rotogravure process hi wood-pulp fiber based, synthetic, emaw laminated substrate-a print chhuahna atana direct transfer method a ni a, chung zingah chuan:

—PET, OPP, nylon, leh PE,PVC,Cellophane ang chi film te

Rotogravure hmanga print chhuah dan

Rotogravure printing hi printing machine automation degree sang tak avang hian plate quality a tha a, chuvangin process operation chu lithographic printing aiin a awlsam zawk a, master a awlsam zawk a, process flow chu hetiang hi a ni:

Printing hmaa inbuatsaihna → cylinder plate-ah → color registration siamrem → formal printing → post-press processing

Process sawifiahna

Gravure printing process chhung hian printing cylinder chu ink pan ah a inher a, chutah chuan engraved cells te chu ink in a khat a ni. Cylinder chu ink pan atanga hla taka a inher chuan ink tam lutuk chu doctor blade hmangin a paih chhuak thin. A chhehvel lamah chuan cylinder chu substrate nen a inzawm tir a, chu chu rubber khuh impression roller hmangin a press a ni.

Roller pressure bakah substrate capillary draw te hian printing cylinder chhunga cell atanga ink chu substrate chung lamah direct transfer a thlen a ni. Printing roller chu ink pan chhunga a inher leh chuan substrate-a printed area chu dryer kaltlangin a kal zel a, a hnuaia printing unit-ah a kal a, chu chu a tlangpuiin a rawng danglam emaw, varnish emaw coating emaw pawh a ni thei.

Automatic side leh length register control system hmangin color to color registration dik tak siam theih a ni.

Web-fed printing press tan chuan rawng tin print a nih hnuah leh coating eng pawh dah a nih hnuah web chu ‘rewound’ a ni a, roll siam zawh tawh a ni.

Tunah chuan kan ngaih pawimawh ber chu printing process hian direct-in link pawimawh ber pakhat - color registration-a printing quality a nghawng thei a ni

Tunah chuan gravure printing machine tam zawk chuan pattern registration atan automatic color registration system an hmang dawn a, hei hian registration efficiency leh printing quality nasa takin a tichangtlung a ni.

Web gravure printing machine-ah chuan automatic overprinting device dah a ni. He device hi scanning head, pulse generator, electronic controller, adjusting motor, overprint adjusting roller leh a dangte a awm a ni.

Scanning head kaltlangin printed sheet-a overprint mark a awm chuan, pulse signal chu electronic controller-ah a thawn ang a, mark rawng hmasa ber hma emaw, a hnu emawa overprint mark rawng pahnihna a dik lo a nih chuan, pulse hun lo awm dan chu a inthlau ang a, chuvangin electronic controller chuan motor chu a regulate tan a, chutiang chuan regulating rollers inkara overprint rawng hmasa ber leh rawng pahnihna chuan movement tlemte a nei ang, to overprinting tihsual tihbo.

Chu bakah, a hnuaia thilte hian printing quality leh efficiency tichhe thei thilte pawh a awm a, mahse a solution dik tak kan nei ang

a) T he ink hi a rawng a inang lo

Printed materials-ah hian periodic ink color a inthlak thin phenomenon hi a ni. A tihbo dan tur chu: printing plate cylinder roundness siamthat te, squeegee angle leh pressure siamthat emaw squeegee chu a thara thlak emaw te a ni.

b) Fuzzy leh linty print te

Printed image level leh level, paste, image sir lama burrs awm thin phenomenon te. Elimination methods chu: substrate chunglam atanga static electricity lakchhuah te, ink-a polar solvents dah te, printing pressure dik taka tihpun te, leh squeegee awmna tur siamrem te leh a dangte a ni.

c) blocked version a ni

Printing plate mesh-a ink drying, emaw printing plate mesh hole-a paper hair-a khat a ni a, paper powder phenomenon, blocking an tih. Elimination methods chu: ink chhunga solvent awm zat tihpun, ink drying speed tihtlem, high surface strength paper printing hman te hi a ni.

d) Ink a luang chhuak

Print-a field part-a spot lo lang phenomenon. Elimination methods te chu: hard ink blending oil dah belh a, ink viscosity tihchangtlun. Squeegee angle siamrem la, printing speed tisang la, deep-cavity printing plate chu shallow-cavity printing plate hmangin thlak rawh.

e) Scratch tih hi a ni

Print-ah hian squeegee hnuhma a awm. Elimination methods chu: printing-a foreign matter pawlh tel lovin ink thianghlim hman tur a ni. Ink viscosity, dryness leh adhesion te chu siamrem rawh. Squeegee quality sang tak hmang la, squeegee leh printing plate inkar angle chu siamrem rawh.

OYANG-a design engineer-te chuan printing process-a harsatna hrang hrang awm angin machine structure chu an zirchiang a, an siam ṭha a, Honor Sereis ELS Rotog ravure Printing Machine chu a hmangtute leh industry-te pain point chinfelna thlirna aṭangin an design a ni.
