How much ink does 70gsm Fast Dry Sublimation Paper absorb?

As a supplier of 70gsm Fast Dry Sublimation Paper, I often get asked about the ink absorption capacity of our product. This is a crucial question for businesses and individuals involved in sublimation printing, as it directly impacts the quality and cost - effectiveness of the printing process. In this blog post, I'll delve into the science behind ink absorption in 70gsm Fast Dry Sublimation Paper and provide you with a comprehensive understanding.

Understanding Sublimation Printing and Paper

Before we discuss ink absorption, it's essential to understand the basics of sublimation printing. Sublimation printing is a process where solid ink (dye) is converted directly into a gas without going through the liquid phase when heated. This gas then bonds with the polyester fibers in the substrate, creating a permanent, high - quality print. The sublimation paper acts as a carrier for the ink during the transfer process.

Our Subli Paper is designed specifically for high - speed sublimation printing. The 70gsm (grams per square meter) weight is a popular choice in the industry because it offers a good balance between durability and ink absorption. The fast - dry feature ensures that the ink sets quickly on the paper, reducing the risk of smudging and allowing for faster production times.

Factors Affecting Ink Absorption

Several factors influence how much ink 70gsm Fast Dry Sublimation Paper can absorb. These include the paper's porosity, surface treatment, and the type of ink used.

Porosity

The porosity of the paper is a key factor in ink absorption. A more porous paper has more tiny holes or spaces between its fibers, allowing the ink to penetrate deeper into the paper. Our 70gsm Fast Dry Sublimation Paper is engineered to have an optimal level of porosity. This means that it can absorb a sufficient amount of ink to create vivid and detailed prints, while also preventing the ink from bleeding through to the other side of the paper.

Surface Treatment

The surface treatment of the paper also plays a significant role. Our sublimation paper undergoes a special coating process that enhances its ink - holding capacity. This coating helps to keep the ink on the surface of the paper, allowing it to be transferred more effectively during the sublimation process. The fast - dry feature is a result of this coating, which helps to evaporate the water in the ink quickly, leaving behind the dye.

Type of Ink

The type of ink used in sublimation printing can vary, and different inks have different absorption rates. Water - based sublimation inks are the most common type. These inks are absorbed well by our 70gsm Fast Dry Sublimation Paper because of its porous structure and surface treatment. However, the absorption can also be affected by the ink's viscosity and the concentration of the dye.

Measuring Ink Absorption

To determine how much ink our 70gsm Fast Dry Sublimation Paper can absorb, we conduct a series of tests in our laboratory. We use a standard method where we print a series of solid - color blocks on the paper using a calibrated sublimation printer. After printing, we weigh the paper before and after the printing process to measure the amount of ink absorbed.

On average, our 70gsm Fast Dry Sublimation Paper can absorb approximately 10 - 15 grams of ink per square meter. This amount can vary depending on the factors mentioned above, such as the type of ink and the printing conditions. For example, if the ink has a higher viscosity, it may not be absorbed as easily, resulting in a lower absorption rate.

Importance of Ink Absorption in Sublimation Printing

The ink absorption capacity of the sublimation paper is crucial for several reasons. Firstly, it affects the quality of the print. If the paper cannot absorb enough ink, the colors may appear dull and washed out. On the other hand, if the paper absorbs too much ink, it can lead to bleeding and smudging, which can ruin the print.

Secondly, ink absorption impacts the cost - effectiveness of the printing process. By using a paper with the right ink absorption capacity, you can ensure that you are using the optimal amount of ink. This reduces waste and lowers the overall cost of production.

Comparing with Other Papers

When compared to other types of sublimation papers, our 70gsm Fast Dry Sublimation Paper offers several advantages. Some lower - weight papers may have a higher ink absorption rate, but they are often less durable and more prone to tearing. Higher - weight papers, on the other hand, may be more durable but may not absorb ink as efficiently.

Our Sublimation Paper For Heat Transfer and Transfer Paper For Sublimation Printing are designed to provide the best of both worlds. They offer a good balance between ink absorption and durability, making them suitable for a wide range of sublimation printing applications.

Tips for Optimizing Ink Absorption

To get the most out of our 70gsm Fast Dry Sublimation Paper, here are some tips:

• Use the right ink: Make sure to use high - quality water - based sublimation inks that are compatible with our paper.
• Adjust the printer settings: Set the printer to the appropriate resolution and ink density for the best results. A higher resolution may require more ink, but it can also produce more detailed prints.
• Store the paper properly: Keep the paper in a cool, dry place to maintain its porosity and surface treatment. Exposure to humidity can affect the paper's ink absorption capacity.

Conclusion

In conclusion, our 70gsm Fast Dry Sublimation Paper has an average ink absorption capacity of 10 - 15 grams per square meter, which can vary depending on several factors. Its optimal porosity, surface treatment, and fast - dry feature make it an excellent choice for sublimation printing. Whether you are a small business or a large - scale manufacturer, our paper can help you achieve high - quality, cost - effective prints.
