Monarch LB Yeti White – Low Cure Plastisol Ink

Printing Directions for Monarch Yeti White Ink on Polyester:

Preparation: Ensure that the polyester fabric is clean and free from any contaminants. Pre-treat the fabric if required, following the manufacturer’s recommendations.

Screen Preparation: Use an emulsion specifically made for use with plastisol inks when coating your screens. To combat dye migration and achieve better ink coverage, opt for a lower mesh count such as 110 or 125. The lower mesh count will deposit a thicker layer of ink, enhancing color vibrancy and preventing dye migration.

Ink Mixing: Mix the Monarch Yeti White Ink thoroughly before use to achieve consistent color and texture. If you plan to create a custom Pantone color using this system, you can utilize the Monarch Color Mixing System available at the following link: Monarch Color Mixing System. This tool will aid you in achieving accurate Pantone matches for your printing projects.

Underbase/Gray Blocker: For challenging materials like polyester camo, consider using a white underbase or a gray blocker. The underbase will help enhance the vibrancy of the colors and prevent the fabric color from affecting the final print’s brightness.

Printing: Apply the ink to the screen and position it correctly over the garment. Flood the screen and ensure the ink fully covers the design area.

Print Stroke: Use a smooth and even print stroke to ensure even ink distribution on the fabric. For optimal results, use a single print stroke for one-stroke coverage whenever possible.

Curing Temperature: Polyester is sensitive to heat, and dyes in the fabric may migrate at high temperatures. To prevent dye migration and maintain the fabric’s color integrity, ensure your conveyor dryers are set between 290 to 320 degrees Fahrenheit (143 to 160 degrees Celsius). The Monarch Yeti White Ink cures at this temperature range, providing excellent adhesion and durability.

Curing Time: Maintain the garment inside the conveyor dryer for a full minute and a half. This duration allows the ink to fully cure and adhere to the fabric. Always perform a stretch test after curing to ensure the ink does not crack and is fully cured onto the garment.

Cooling and Stacking: Be cautious when stacking freshly cured shirts, as certain dyes can gas and transfer onto the back of the next shirt if they are stacked while too hot. To prevent this, we recommend making three stacks so each shirt has longer to cool and reduce the risk of dye transfer. Alternatively, consider adding a fan cooling bar at the end of your conveyor belt exit feed to enhance cooling and prevent unwanted dye migration.

Testing and Quality Control: Perform a wash test on a sample garment to ensure the ink adheres properly and retains its color after washing. Check for any issues related to dye migration or color changes.

Clean Up: Clean screens and equipment thoroughly after printing to maintain their longevity and ensure consistent print quality in future runs.

Storage Instructions:

To ensure the longevity and optimal performance of Monarch Yeti White Ink, it is essential to follow proper storage guidelines:

• Room Temperature Storage: Store the ink containers in a cool and dry environment at room temperature. Avoid exposing the ink to extreme temperatures, such as freezing or high heat, as this can negatively impact the ink’s consistency and printing properties.
• Avoid Direct Sunlight: Keep the ink away from direct sunlight or strong UV light sources. Prolonged exposure to sunlight can cause the ink to gel in the container and lead to undesirable changes in consistency.
• Avoid Warm Temperatures: Monarch Yeti White Ink is a low-cure ink, and exposure to warmer temperatures can cause gelling, making it challenging to print or even ruin the product. Prevent storing the ink in areas prone to excessive heat.
• Proper Sealing: Always ensure that the ink containers are tightly sealed after each use. This prevents air and contaminants from entering the containers, maintaining the ink’s quality and preventing premature drying or thickening.
• Regular Inspection: Periodically check the ink containers for any signs of spoilage, contamination, or change in consistency. If any abnormalities are detected, refrain from using the ink and contact the manufacturer or supplier for assistance.

By following these storage instructions, you can prolong the shelf life of Monarch Yeti White Ink and maintain its smooth texture and printing properties, ensuring exceptional results for your screen printing projects. Remember, proper ink storage is essential for achieving consistent and high-quality prints.

Note: Always follow safety guidelines and wear appropriate protective gear when working with plastisol ink and using conveyor dryers. Proper ventilation in the printing area is essential to minimize exposure to fumes.

By following these directions, using the right emulsion and mesh count, utilizing the Monarch Color Mixing System for custom Pantone colors, and implementing careful cooling and stacking practices, you can achieve exceptional results when printing with Monarch Yeti White Ink on polyester. Happy printing!

Before proceeding with the printing process, it is crucial to perform a test on a sample garment using Monarch Yeti White Ink. Testing the ink on a sample garment ensures that the color remains consistent during the curing process and in the days following printing.
