As a trusted supplier of 90gsm Fast Dry Sublimation Paper, I often receive inquiries from customers about the shrinkage rate of prints on our product. Understanding the shrinkage rate is crucial for achieving high - quality, accurate prints, especially in industries where precision is key, such as textile printing, promotional item production, and signage manufacturing. In this blog post, I will delve into the factors affecting the shrinkage rate of prints on 90gsm Fast Dry Sublimation Paper and provide some insights based on our experience and industry knowledge.
Understanding Sublimation Printing
Before we discuss the shrinkage rate, it's important to understand the sublimation printing process. Sublimation printing is a method of transferring dye onto a substrate, typically a polyester - based material, using heat and pressure. The dye inks are first printed onto sublimation paper, and then, through the application of heat (usually around 180 - 220°C) and pressure, the dye turns from a solid to a gas without passing through the liquid state and bonds with the fibers of the substrate.
Factors Affecting Shrinkage Rate
- Paper Quality: Our 90gsm Fast Dry Sublimation Paper is engineered to have a relatively low shrinkage rate. The paper is designed with a special coating that helps to maintain its dimensional stability during the sublimation process. The fast - dry feature ensures that the ink is absorbed quickly and evenly, reducing the chances of distortion due to uneven drying. However, variations in the manufacturing process of the paper can still lead to minor differences in shrinkage rates. For example, if the paper is not dried uniformly during production, it may be more prone to shrinkage.
- Ink Type and Quantity: Different types of sublimation inks have different properties, and they can affect the shrinkage rate of the prints. Some inks may have a higher water content, which can cause the paper to expand during printing and then shrink as the water evaporates during the sublimation process. Additionally, the quantity of ink applied to the paper also matters. Over - saturation of the paper with ink can increase the shrinkage rate, as there is more moisture and dye to be removed during sublimation.
- Sublimation Conditions: The temperature, pressure, and duration of the sublimation process are critical factors. Higher temperatures can cause the paper to shrink more, as the heat can break down the fibers of the paper and cause it to contract. Similarly, excessive pressure can also lead to shrinkage. The optimal sublimation conditions for our 90gsm Fast Dry Sublimation Paper are a temperature of around 200°C, a pressure of 3 - 5 bar, and a duration of 20 - 30 seconds, depending on the substrate. Deviating from these conditions can result in a higher shrinkage rate.
- Substrate Material: The material onto which the print is transferred can also influence the shrinkage rate. Polyester - based substrates are generally more stable and have a lower shrinkage rate compared to other materials. However, if the substrate has a high stretch or is not properly pre - treated, it can cause the print to appear distorted or have a higher apparent shrinkage rate.
Measuring the Shrinkage Rate
To measure the shrinkage rate of prints on 90gsm Fast Dry Sublimation Paper, we typically use a simple method. First, we print a test pattern on the paper, which includes a grid of known dimensions. After sublimating the print onto the substrate, we measure the dimensions of the grid on the substrate and compare them to the original dimensions on the paper. The shrinkage rate is then calculated using the following formula:
[Shrinkage\ Rate(%)=\frac{Original\ Dimension - Final\ Dimension}{Original\ Dimension}\times100]
In our tests, we have found that the shrinkage rate of prints on 90gsm Fast Dry Sublimation Paper is usually between 1 - 3%. This is relatively low compared to some other types of sublimation papers on the market.
Comparison with Other GSM Papers
We also offer 100gsm Fast Dry Sublimation Paper, 63gsm Fast Dry Sublimation Paper, and 55gsm Fast Dry Sublimation Paper. Generally, the higher the GSM (grams per square meter) of the paper, the lower the shrinkage rate. The 100gsm paper has a more robust structure, which can better withstand the heat and pressure of the sublimation process, resulting in a slightly lower shrinkage rate compared to the 90gsm paper. On the other hand, the 55gsm and 63gsm papers are lighter and may have a slightly higher shrinkage rate, but they are more cost - effective and suitable for applications where precision is not as critical.
Minimizing Shrinkage Rate
To minimize the shrinkage rate of prints on our 90gsm Fast Dry Sublimation Paper, we recommend the following tips:
- Use High - Quality Inks: Choose sublimation inks that are specifically designed for use with our paper. These inks are formulated to work well with the paper's coating and have a lower water content, reducing the risk of shrinkage.
- Optimize Printing Settings: Adjust the print settings on your printer to ensure that the ink is applied evenly and in the right quantity. Avoid over - saturating the paper.
- Follow Sublimation Guidelines: Adhere to the recommended sublimation temperature, pressure, and duration. Use a calibrated heat press to ensure consistent results.
- Pre - Treat Substrates: If necessary, pre - treat the substrate to improve its stability and reduce the chances of distortion during sublimation.
Conclusion
The shrinkage rate of prints on 90gsm Fast Dry Sublimation Paper is influenced by multiple factors, including paper quality, ink type and quantity, sublimation conditions, and substrate material. By understanding these factors and following the recommended guidelines, you can achieve high - quality prints with a relatively low shrinkage rate. Our 90gsm Fast Dry Sublimation Paper offers a good balance between cost - effectiveness and performance, making it a popular choice for a wide range of sublimation printing applications.
