What is the Advantage and Disadvantage of textile pigment ink

In today's competitive world of printing, print quality has become something of great significance. The quality, as well as the durability of prints, is greatly impacted by the type of ink used in the printing industry. The purpose of this article is to explain how dye ink and pigment ink differ from one another. You may choose the best ink for your particular printing needs by understanding their technical differences, performance on various media, advantages, and limitations.

Definition and Composition of Dye and Pigment Ink (Technical Difference)

• Dye ink consists of colorant particles dissolved in a liquid. These colorants are composed of small molecules that can easily penetrate the printing media. By nature, the dye colorants are more vibrant and hence produce vivid and sharp colors on prints, having a wide color gamut. 

• Pigment ink is made up of tiny solid pigment particles suspended in a liquid carrier. These particles sit on the surface of the printing media rather than being absorbed like dye ink. Pigment ink is known for its exceptional lightfastness and durability. By nature, these pigment colorants are not as vibrant as dye colorants, thus resulting in a color gamut not as wide as dye inks. 

Performance on different media (Dye Ink Vs. Pigment Ink)

• Dye ink excels in printing on glossy and coated papers, as well as certain specialty photo papers. It delivers brilliant colors and smooth gradients, making it ideal for photo printing.
• Pigment ink performs exceptionally well on a wide range of media, including plain paper, matte paper, and specialty fine art papers. Its ability to sit on the surface of the paper results in sharp and detailed prints suitable for documents and archival-quality art prints.

Advantages of Dye Ink 

• Superior color performance and vibrancy, make it perfect for photo printing.
• Faster printing speed and drying time due to its quick absorption into the paper.
• More cost-effective than pigment ink.

Advantages of Pigment Ink

• Exceptional print longevity and fade resistance, ensuring the longevity of prints without significant color degradation.
• High water and smudge resistance, ideal for producing prints that need to withstand environmental factors.
•  Excellent for producing sharp and detailed prints, perfect for documents and artwork.

Why do Large Format Printers have more colors?

If one looks at the number of colors that exist in a desktop printer, one would find that this number lies between 4 to 6, sometimes more. On the other hand, a large format printer normally has 8 or more colors. Now why is that exactly?

Actually, large-format printing applications have durability as a deciding factor of quality. Hence almost all large format printers use pigment inks. Now, since pigment inks do not have such a wide color gamut, these printers use a higher number of colors to achieve the required gamut.

Choosing the Right Ink for Your Printing Needs

• • When deciding between dye ink and pigment ink, consider the following factors
    • Intended use of prints: Determine whether you'll mainly be printing photos, documents, or art prints.
    • Desired longevity of prints: Consider how long the prints will need withstanding environmental factors
    • Budget considerations: Generally, pigment inks are more expensive than dye inks. Understanding your printing needs precisely is important to know the right ink type. 
• Printer type and compatibility: Check if your printer works on dye, pigment, or both inks before using a particular ink on them
• Recommendations for specific applications
  • Photo printing: Opt for dye ink for its vibrant colors and fast printing speed.
  • Document printing: Opt for pigment ink for its fade-resistant properties and sharp image quality.
  • Art and design printing: Choose pigment ink for its archival quality and exceptional detail. But it may require a machine with more colors to print.

Best Practices for Printing with Dye Ink and Pigment Ink

• Proper handling and storage of ink cartridges ' Store ink cartridges in a cool, dry place away from direct sunlight.
• Maintenance tips for inkjet printers ' Follow the printer manufacturer's guidelines for cleaning and maintenance to ensure optimal performance.
• Choosing the right paper for optimal results ' Select an appropriate paper type for the best print results, whether glossy, matte, or fine art paper.

Conclusion

The output of your prints can be greatly affected by the ink that you choose, whether it be dye or pigment. While pigment ink produces exceptionally detailed, long-lasting, fade-resistant prints, dye ink excels at producing vivid photos. You may make an informed choice that ensures the best outcomes for your projects by taking into account your unique printing requirements and the benefits of each ink type. To maximize the effectiveness and durability of your prints, keep in mind to adhere to recommended ink and printer maintenance procedures.

Definition of Pigment

A substance in particulate from that is substantially insoluble in a medium but which can be mechanically dispersed in this medium to modify its color and light ' scattering properties.

In other words, Pigments are insoluble coloring matter mostly mineral origin have been used for the coloration of metal wood, stone, and textile material.

Definition of Pigment Printing

Pigments are colors which do not dissolve and penetrate into the fibres. They have not to be applied together with a film forming binder. More than 50% of all printing colors are pigment types. It represents an alternative to direct printing. In this system there is no need to carry out a steaming process, as steaming is replaced by polymerization (generally carried out simultaneously with drying).

This type of printing process is very simple, low-cost and can be carried out easily on all types of fabrics, particularly on blends, since pigments can adhere to all fibres; there is no need to use dyes of different color classes. On the other hand, the adhesives, which bind the pigment to the fabric, can give serious problems when the fabric hand varies. For prints with a low coverage ratio, the hand variation can be acceptable but it is not when the coverage ratio is high or at least for all uses. Furthermore, the pigment lies on the surface and has low fastness to friction (this depends mainly upon the type and quantity of binding agent and upon the polymerization degree). Some valid alternatives to this type of printing can give special effects such as printing with swelling agents (generally synthetic polyurethane-base pastes are used), with covering pigments and glitter (metal powders or particles of plastic materials) etc.

Advantages of Pigment Printing

• Applicable to natural and synthetic fibre.
• Wide range of color can be produced.
• Can be used for dope dyeing for filament yarn.
• Easily applicable.
• Less expensive.
• Maximum output of goods because of the elimination of washing-off, quick sampling and high printing speed.
• It presents the fewest problems for the printer of all the coloration processes, with regard to labor costs, equipment and reliability of production.
• Properly produced pigment prints, using selected products, have an unsurpassed fastness to light and good general fastness properties.
• Extremely well suited for color resist effects, for example, under azoic and reactive dyes.
• From the economical point of view, pigment printing, using pastes free from white spirit, is more acceptable than any other systems, excepting transfer printing methods.

Disadvantages of Pigment Printing

• Not controllable for the binder film.
• Use of solvent like kerosene, spirit etc can produce problems like flammability, odor, pollution etc.
• The jamming up of equipment and air and water pollution is observed.
• Wet and rubbing fastness is average.
• The handle of the printed goods is often unduly hard because of the large amounts of external cross linking agents.
• Are sensitive to crushing during roller printing and pigment printing needs shallow engravings on screen printing.
• The original surface of the textile material is covered by the binder film. This is occasionally aesthetically effective but usually undesirable.
