Printing methods

•Traditional printing•Conventional printing•Modernized printing

Traditional printing

•Hand block printing•Batik printing•Tie- dye printing•Ikat printing

Hand block printing

•It is very slow method•It is done where the labor is cheap•It can’t be produced in large quantity

costlyDesigns are carved with wooden or metal blocks in that dye paste is applied and press firmly wherever we need

Batik printing

The patterns are generally in geometric, floral, bird or animal

•costly

Designs are made withwax on a fabric which issubsequently immersed ina dye to absorb a colouron the unwaxed portions

Two methods•Tjanting•Tjap

Dye is resisted by knots that are immersed in the dye bath. The outside of knotted portion is dyed, but the inside is not penetrated if the knot is

firmly tied. Partial penetration occurs when the knot is not tight

Tie dye printing

•Costly process

The process can be repeatedly by making additional knots in the fabric

Ikat printing

It is a ancient method of fabric coloration by tie-dyeing bundles of warp and /or weft yarns prior to weaving is ikat.

The colours usually indigo, red, and brown are placed along the length of the yarns in anticipation of design that is to be woven

Conventional printing

Roller printingWarp printingFlat bed screen printingRotary screen printingStencil printing

Roller printingRoller printing is the machine method of printing designs on cloth by engraving rollers. It turns out colour- designed fabrics in vast quantities at the rate of 1000 to 4000 yards an hour. It is very in expensive process when compare to hand method

Warp printing

Warp printing is roller printing applied to warp yarns before they are woven into fabric. Fine white or neutral – coloured filling yarns are generally used for weaving so that the design on the warp will not be obscured

Stencil printing

In stencil printing thedesign must first cut incardboard, wood or metal.The stencil may have a finedelicate design or there maybe large space throughwhich a great amount ofcolour can be applied. Astencil design usually limitedto application of only onecolour and is generally usedfor narrow widths of fabric.

Modernized methods of printing

•Digital (ink-jet ) printing•Heat transfer printing•Electrostatic printing•Foil printing

Digital ink jet printing

•In this instead of wax based ink normal black ink is used for image formatting on screen.• This ink system is very cheap and works trouble free and offers a excellent engraving results

Heat transfer printing

•Moving a design from one surface to another is known as transfer printing. •Generally from paper to a textile material.

Two types:

Dry transfer printing

Wet transfer printing

Electrostatic printing

The dye is spread on a screen bearing the design, and the fabric is passed into an electrostatic field under the screen, which is held about 0.5 inch above the cloth.

A process of mixing a finely powered dye with a carrier, such as a natural or synthetic resin, that has high dielectric properties for electrostatic printing.

Foil printing

• The transfer of the foil topaper or plastic is done by usinga metal die, heat and pressure.• Foil printing can be done insingle, multiple colours, rainbowcolour or in a holographicpattern.
