Style of printing

The 'style of printing refers to the method used for producing a given design on the fabric. The three main styles of printing are given below

style of printing



 Direct Printing 

In this style the color is applied directly to the cloth by printing and is fixed by steaming or baking. This style of printing can be divided into the following three sub-groups
       (a) white and dyed ground.
       (b) semi-blotch, and
       (c ) blotch.
Following class of dyes are applied commonly in direct style of printing: Vats, indigosols, azoics (rapidogen), pigments, reactive and aniline Black 

Discharge Printing

In this style, a dyed ground is removed locally leaving a white or coloured pattern on the original ground.


Vat dyes are used as illuminating colored effects and Rongalite and alkali along with suitable chemicals act as discharging component for both white and colored discharge. Following ground shades are commonly empleyed for getting white and coloured discharges: Direct, azoic, reactive, indigosol derived from indigoid vat dyes


 Resist Printing

The object of this style is to produce a pattern on a culoured ground by first printing on the white cloth a substance that will prevent the fixation of any colouring matter applied over it
In resist styles of printing, vat, rapidogen, pigment, and reactive dyes can be used as illuminating colours while a number of chemicals as resisting agent. Increasing printing effects can be produced by using the following

Metal Printing:  

  Metallic powders are applied to produce designs in gold, silver, etc. They are printed with synthetic binders such as Binder SL.N

Crimp Printing:


This printing is carried out to give crimp effect to the fabric at the printed places .Caustic Soda up to 50 % strength is incorporated in British gum paste and is printed on' the cloth. The whole process depends upon the tensionless drying of the printed cloth and slack washing in batches
.

Khadi Printing : 

 Production of matt white and matt coloured effects can be brought about by titanium dioxide. Pigment powder, etc. The deeper the dye, the better is the print.

Flock Printing:

In this style, velvet type of designs are produced on plain cloth by fixing silk or man-made fiber flock with an adhesive during the printing operation
