In the field of screen printing, plastisol inks for screen printing are renowned for their vibrant colors, excellent coverage, and superior washability. Rapid cure plastisol ink, as a standout among them, is highly favored by printers for its rapid curing characteristics, which significantly boost production efficiency. However, even the best plastisol inks, such as best plastisol ink or cmyk plastisol ink, can encounter issues during the printing process. This article will delve into the common faults encountered when using rapid cure plastisol ink in printing and provide effective solutions to help ensure print quality and production efficiency.
I. Ink Clogging the Mesh
Problem Description:
During screen printing with rapid cure plastisol ink, the ink may clog the mesh, resulting in incomplete or blurred printed patterns.
Cause Analysis:
- The ink particles are too large or contain impurities.
- The mesh count is too high, not matching the ink particle size.
- The ink dries too quickly during the printing process, causing mesh clogging.
Solutions:
- Thoroughly stir the rapid cure plastisol ink before use to ensure even distribution of ink particles.
- Choose a mesh count that matches the ink particle size.
- Control the printing environment to prevent the ink from drying too quickly. You can increase the humidity in the printing environment or use a slow-drying agent.
II. Ink Bubbling Issues
Problem Description:
Bubbles may appear in the rapid cure plastisol ink during the printing process, affecting the overall aesthetics of the printed product.
Cause Analysis:
- The ink is not stirred sufficiently, containing air.
- The printing speed is too fast, allowing insufficient time for the ink to level out.
- The printing environment temperature is too high, causing rapid solvent evaporation in the ink.
Solutions:
- Stir the ink thoroughly to ensure all air is removed.
- Adjust the printing speed to allow enough time for the ink to level out.
- Lower the printing environment temperature to reduce solvent evaporation.
III. Poor Ink Curing
Problem Description:
The printed pattern fails to dry completely during the curing process, resulting in printed products that are not washable or where the colors come off.
Cause Analysis:
- The curing temperature is too low or the curing time is insufficient.
- The ink and substrate are not compatible, leading to poor curing results.
- The ink contains too much moisture or solvent.
Solutions:
- Increase the curing temperature or extend the curing time.
- Choose a substrate that is compatible with rapid cure plastisol ink.
- Ensure the ink is dry before use, avoiding excess moisture or solvent.
IV. Ink Sticking to the Mesh
Problem Description:
During the printing process, rapid cure plastisol ink may adhere to the mesh, resulting in unclear printed patterns.
Cause Analysis:
- The ink viscosity is too high.
- The mesh tension is insufficient, allowing ink penetration.
- The printing squeegee is not stiff enough or is at an improper angle.
Solutions:
- Adjust the ink viscosity using a thinner or thickener.
- Check and adjust the mesh tension.
- Replace the squeegee with one of suitable hardness and adjust its angle.
V. Uneven Color
Problem Description:
The printed product has uneven coloring, with color differences or patches.
Cause Analysis:
- The ink is not stirred uniformly, resulting in uneven color distribution.
- Insufficient or excessive ink supply during the printing process.
- The substrate surface is uneven, affecting ink adhesion.
Solutions:
- Thoroughly stir the ink to ensure even color distribution.
- Control the ink supply to ensure stability during the printing process.
- Choose a substrate with a smooth surface or preprocess it to improve ink adhesion.
VI. Ink Drying Too Quickly or Too Slowly
Problem Description:
Rapid cure plastisol ink dries too quickly or too slowly during the printing process, affecting printing efficiency and quality.
Cause Analysis:
- The printing environment’s temperature and humidity are unsuitable.
- The solvent content in the ink formula is inappropriate.
- The printing speed does not match the ink drying rate.
Solutions:
- Adjust the printing environment’s temperature and humidity to the appropriate range.
- Adjust the solvent content in the ink formula according to printing needs.
- Adjust the printing speed to match the ink drying rate.
VII. Poor Adhesion of Ink to the Substrate
Problem Description:
The ink on the printed product easily falls off or wears away.
Cause Analysis:
- The substrate surface tension is too low, making it difficult for the ink to adhere.
- The ink and substrate material are not compatible.
- The ink is not fully cured.
Solutions:
- Pretreat the substrate to increase its surface tension.
- Choose rapid cure plastisol ink that is compatible with the substrate material.
- Ensure the ink is fully cured.
VIII. Blurred Edges of Printed Patterns
Problem Description:
The edges of the printed patterns are not clear, appearing blurred.
Cause Analysis:
- The distance between the mesh and the substrate is too large.
- The printing squeegee pressure is too high or too low.
- The ink has poor fluidity.
Solutions:
- Adjust the distance between the mesh and the substrate to an appropriate range.
- Adjust the pressure of the printing squeegee to ensure clear printed patterns.
- Use rapid cure plastisol ink with good fluidity.
IX. Ink Separation Phenomenon
Problem Description:
During the printing process, rapid cure plastisol ink separates, resulting in uneven coloring of the printed patterns.
Cause Analysis:
- The ink has been stored for too long without sufficient stirring.
- The ratio of pigments to resins in the ink formula is inappropriate.
- The printing environment temperature is too high, causing ink separation.
Solutions:
- Stir the ink thoroughly before use to ensure even mixing of pigments and resins.
- Adjust the ink formula to ensure an appropriate ratio of pigments to resins.
- Control the printing environment temperature to prevent ink separation due to excessive heat.
X. Faded Colors After Printing
Problem Description:
The printed colors are lighter than expected, lacking vibrancy.
Cause Analysis:
- The ink concentration is too low.
- Too much ink is lost during the printing process.
- The substrate color is too dark, affecting the ink’s presentation.
Solutions:
- Increase the ink concentration to ensure vibrant colors.
- Check the printing equipment to ensure excessive ink loss does not occur.
- Choose a substrate with a lighter color or apply a base color treatment to improve the ink’s presentation.
