Advantages of Pigment Printing:
The advantages of pigment printing are well known and the process has grown in popularity worldwide in recent years as it offers several advantages over other styles of printing. These include brilliant prints with high light fastness, ease of application in color matching, flexibility in its applicability to natural and synthetic fibers and avoidance of the final wash off resulted in a complete elimination of any effluent disposal problems.

Applicable to natural and synthetic fiber.

Pigment printing is most economical printing process and allows maximum output of goods because of the elimination of washing off, quick sampling and high printing speeds.

The advantage of pigment printing is that the process can be done without subsequent washing.

Simple Application

Simple technical process without wet after treatment

Little requirements for machinery equipment

Pigment printing can be applied to all substrate which are of interest to the printer, including glass fibers, PVC and imitation leather, subject to some limitations in color depth. It is extremely well suited for color resist effects, for example under azoic and reactive dyes.

Mistakes in pigment printing can be recognized quickly.

Pigment printing presents the fewest problems for the printer of all coloration process, with respect to labour costs, equipment and reliability of production.

Progress in quality of pigment printing

New synthetic polymers Good fastness properties, soft handle

Aisadvantages of Pigment Printing:

Not controlable for the binder film.

Handling properties of the pigment printing is rough because of having excessive cross linking agents.

Creates problem on the roller printing because of the bulky products and more engraved rollers.

It is not possible to apply it directly on the fabric. Binder must be used to apply the pigment dye on the fabric. Thus, a coat is created on the surface of the fabric.

During second time printing it has very low effect that is not desirable.

When pigments are over printed the second paste has little effect.

Wet and rubbing fastness is average.

Application of Pigment Printing:

Uses of Pigment printing is wide range. The garments of the women which are made by cotton, polyester or viscose blends are printed by pigments if the medium color depths are needed. Decorative curtain, towels are printed by pigments. Pigment printing also used in bed linen, aprons, children’s garments, night wear dresses, various cottons and cellulose materials.
