Printing hi printing siam dan tur, direct printing leh indirect printing-ah te then a ni.
Indirect printing tih awmzia chu layout-a printing ink chu cylinder-ah transfer hmasak a ngai a, chutah chuan ink chu cylinder hmangin printing material-ah a transfer a ngai a ni. Rubber printing machine tia hriat lar tak ang chi te pawh chutiang zinga mi chu a ni. Direct printing plate tan chuan printing pattern chu a hnunglam atanga image a ni a, indirect printing plate tan chuan printing pattern chu positive image a ni.
Printed products chu printed part leh non-printed part inkara printing process chhunga siam chhuah a nih thu principle ang chuan, a chi hnih-ah then theih a ni a, chungte chu physical printing (physicalprinting) leh chemical printing (chmiacalprinting) te an ni.
Physics printing-ah chuan printing ink chu printing part-a accumulation leh bearing chi khat a ni a, printing tel lo part chu concave emaw convex emaw a ni a, chu chu printing part nen a san zawng a danglam a, printing ink nen a stain theih loh a, a blank a awm thei bawk. Chuvangin, printing part atanga print tur material-a printing ink transfer chu physical leh mechanical action a ni. General gravure printing, letterpress printing, stencil printing, offset printing, etc. zawng zawng hi physical printing (printing surface chu non-printing surface aiin a sang emaw a hniam emaw a ni).
Chemical printing tih hian printing plate-a non-printed part (non-printing surface) a kawk a, chu chu printing ink-ah a innghat lo. A part chu concave emaw convex emaw a hniam vang ni lovin, chemical effect avang hian tui-absorbing leh ink-repellent film a siam chhuak a ni. Printed part (printing surface) hian ink a la a, tui a repel a, non-printed part hian tui a hip a, ink a repel bawk. Tui leh grease te chu an inhnukdawk tih taksa thil thleng a la ni reng. Mahse, printing process chhung hian non-printed part chu water tank solution-ah dah tur a ni a, chu chuan tui a la lut a, a repel a ni. Ink film chu acid leh glue hmanga dah a ngai a, chu chuan carboxy gene-a mucous acid layer chu a supply tur a ni a, chutiang chuan non-printing plate-a printing surface chu grease-in a rawn luh theih loh nan a ni a, chuvangin chemical printing a ni.
