Style of printing
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
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.
The following class of dyes is applied commonly in direct style of printing:
Vats, indigosols, azoic (rapidogen), pigments, reactive, and aniline Black
Discharge Printing
In this style, a dyed ground is removed locally leaving a white or colored pattern on the original ground.Vat dyes are used to illuminate colored effects and Rongalite and alkali along with suitable chemicals act as discharging components for both white and colored discharge. Following ground shades are commonly employed for getting white and colored discharges: Direct, azoic, reactive, indigo sol derived from indigoid vat dyes
Resist Printing
The object of this style is to produce a pattern on a colored ground by
first printing on the white cloth a substance that will prevent the fixation of
any coloring matter applied over it
In resist styles of printing, vat, rapidogen, pigment, and reactive dyes
can be used as illuminating colors while several chemicals as resisting
agents. 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 a crimp effect to the fabric at the printed
places. Caustic Soda of 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-colored effects
can be brought about by titanium dioxide. Pigment powder, etc. The deeper the
dye, the better 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
