How to Apply Velvet Black Plastisol Ink in Silkscreen Printing?

In today’s printing industry, silkscreen printing is favored for its unique artistic effects and wide range of applications. Among the numerous inks, velvet black plastisol ink has become the first choice for many printers due to its outstanding gloss, full black effect, and soft touch.

I. Characteristics and Advantages of Velvet Black Plastisol Ink

Velvet black plastisol ink is renowned for its unique black gloss and soft touch. Compared to ordinary plastisol inks, it better exhibits a deep black effect and delicate touch, making it ideal for printed materials requiring high texture and artistic effects.

  1. Gloss and Black Effect
    The black effect of velvet black plastisol ink is full and glossy, presenting a noble and elegant visual effect.
  2. Soft Touch
    The film layer formed after printing dries is soft and elastic, suitable for textiles or leather products requiring a soft touch.
  3. Durability and Stability
    Velvet black plastisol ink has good durability and stability, resisting daily wear and aging, ensuring the longevity of printed materials.

II. Preparation for Applying Velvet Black Plastisol Ink

Before applying velvet black plastisol ink in silkscreen printing, a series of preparations are required to ensure a smooth printing process and the final printing effect.

  1. Ink Preparation and Mixing
    • Use in Combination with Vegas Gold Ink Plastisol: In some printed materials, it may be necessary to mix velvet black plastisol ink with vegas gold ink plastisol to create a unique contrast between gold and black.
    • Creative Addition of Vortex Plastisol Ink: To increase the layered and dynamic effects of printed materials, try mixing vortex plastisol ink with velvet black plastisol ink to produce swirling or flowing visual effects.
  2. Mesh Screen Production and Adjustment
    • The precision and clarity of the mesh screen are crucial to the final printing effect. Ensure that the mesh screen’s pattern lines are clear, edges are sharp, and it matches the size and shape of the printed material.
    • When using velvet black plastisol ink for printing, it may be necessary to appropriately adjust the tension of the mesh screen to ensure that the ink can pass through it evenly and stably.
  3. Printer Settings and Adjustment
    • Parameters such as the printer’s pressure, speed, and squeegee angle affect the final printing effect. Adjust the printer accordingly based on the characteristics of velvet black plastisol ink.
    • Ensure that the printer’s squeegee is clean and sharp, and maintains the appropriate contact angle with the mesh screen, to ensure that the ink can be transferred to the substrate evenly and completely.

III. Printing Techniques for Velvet Black Plastisol Ink

During the actual printing process, it is essential to master some key printing techniques to ensure that velvet black plastisol ink achieves the best printing effect.

  1. Uniform Ink Application
    • During printing, ensure that velvet black plastisol ink is applied evenly and completely onto the mesh screen. This can be achieved by adjusting the pressure and angle of the squeegee.
    • The squeegee pressure should not be too high or too low. Too much pressure can cause ink to overflow the mesh screen, while too little may fail to transfer the ink completely to the substrate.
  2. Substring Selection and Pretreatment
    • The choice of substrate also greatly affects the final printing effect. Select appropriate printing parameters and ink formulations based on the substrate’s material, thickness, and surface characteristics.
    • Before printing, the substrate needs to be properly pretreated, such as cleaning, decontamination, and drying, to ensure that the ink can firmly adhere to it.
  3. Printing Environment Control
    • The temperature, humidity, and ventilation conditions in the printing environment affect the drying speed and printing effect of velvet black plastisol ink. Ensure that the printing environment is stable and suitable.
    • Regularly check and adjust the printer’s temperature and humidity controllers during printing to ensure that the ink dries evenly and stably.

IV. Combination Use with Other Inks

In silkscreen printing, velvet black plastisol ink is often used in combination with other types of inks to create more colorful printing effects.

  1. Combination Use with W M Plastisol Ink Soft Hand Base
    • W M plastisol ink soft hand base is a plastisol ink with a soft touch. When used in combination with velvet black plastisol ink, it can further increase the softness and comfort of printed materials.
    • When mixing, ensure that the ratio of the two inks is appropriate to avoid affecting the final printing effect and touch.
  2. Use Under Water-Based Ink
    • In some printed materials, it may be necessary to apply a layer of velvet black plastisol ink over water-based ink (water-based ink). This can create a unique visual effect and layered look.
    • When performing this type of printing, ensure that the water-based ink has completely dried and has good adhesion to velvet black plastisol ink. Otherwise, it may lead to ink peeling or poor printing results.

V. Post-Printing Processing and Maintenance

After printing, a series of processing and maintenance tasks are required to ensure the durability and quality of the printed materials.

  1. Drying and Curing
    • After printing, place the printed materials in appropriate temperature and humidity conditions for drying and curing. This ensures that velvet black plastisol ink can fully cure and adhere to the substrate.
    • During the drying and curing process, regularly check the drying status of the printed materials and avoid over-drying or insufficient curing.
  2. Cleaning and Maintenance
    • Printing equipment such as printers, mesh screens, and squeegees require regular cleaning and maintenance to ensure their good working condition and extend their service life.
    • When cleaning, use appropriate cleaners and tools, and avoid using overly abrasive or corrosive substances.

Conclusion

As a high-quality plastisol ink, velvet black plastisol ink has broad application prospects and unique artistic effects in silkscreen printing. By mastering correct printing techniques, selecting suitable substrates and printing environments, and using it in combination with other inks, colorful printed materials can be created. Additionally, post-printing processing and maintenance are important steps to ensure the durability and quality of printed materials.

In the future field of silkscreen printing, with the continuous advancement of technology and market development, velvet black plastisol ink will find even wider applications and in-depth research. We believe that in the near future, it will bring more innovations and breakthroughs to the printing industry.
