What are the reasons for unclear printing on thermal paper?
1. Poor quality of thermal paper: Some cheap thermal paper has uneven ink penetration, resulting in blurry printed text.
2. Insufficient printing temperature: Thermal printers require a certain temperature to fully melt the ink. If the temperature is not sufficient, the ink cannot fully penetrate the paper, resulting in unclear printing.
3. Aging or blockage of the print head: If the print head is used or blocked for a long time, it will affect the ink ejection and lead to poor printing results.
4. Printing speed too fast: Some thermal printers may not have enough time to fully penetrate the ink into the paper when the printing speed is too fast, resulting in unclear printing.
5. Improper printing density setting: If the density set during printing is not appropriate, it can also affect the printing effect and cause unclear text.
Take you to a deeper understanding of the difference between thermal paper and copperplate paper
1. Different storage times
The storage time of copperplate paper adhesive labels is slightly longer than that of thermal paper adhesive labels, so what kind of adhesive label to buy depends on the storage time of the product you are pasting
2. Different temperature effects
Copperplate paper adhesive labels are less affected by temperature, but thermal sensitive paper adhesive labels are more affected by temperature. Therefore, if the adhesive labels attached to the surface of the product are greatly affected by temperature, printing factories generally recommend choosing copperplate paper adhesive labels
3. Different printing options
Copperplate paper needs to be printed together with carbon tape, while thermal paper does not require carbon tape printing and can be directly installed in a barcode printer for printing
4. Differences in Prices
Thermal paper is relatively expensive and can be customized according to customer needs. If there are samples, they can be printed directly based on the samples. The most important thing is that the quotation is not based on how much it costs at the beginning, but on the printing quantity. The more quantity, the more cost-effective the price
How to distinguish the quality of thermal paper?
1. Appearance: If the paper is very white, it indicates that the protective coating and thermal sensitive coating of the paper are unreasonable, and too much fluorescent powder has been added. A better paper should have a slight greenish tint. If the smoothness of the paper is not high or appears uneven, it indicates that the coating on the paper is not uniform. If the paper appears to reflect strong light, it is also due to the addition of too much fluorescent powder, resulting in poor quality.
2. Fire baking: The method of fire baking is also very simple. Use a lighter to heat the back of the paper. If the color appearing on the paper after heating is brown, it indicates that the heat sensitive formula is not very reasonable and the storage time may be relatively short. If there are small stripes or uneven color blocks on the black part of the paper, it indicates that the coating is uneven. High quality paper should be black green (with a hint of green) after heating, and the color blocks should be uniform, gradually fading from the center to the surrounding areas.
3. Comparison and identification of sunlight exposure: After applying a fluorescent pen to the printed paper, place it in the sun to accelerate the reaction of the thermosensitive coating to light. Which type of paper turns black the fastest indicates a shorter shelf life.
The difference between five proof thermal paper and three proof thermal paper
Five anti thermal paper, also known as thermal synthetic paper, has stronger waterproof, oil resistant, alcohol resistant, wear-resistant, scratch resistant, light resistant, and heat-resistant properties. It has a thick protective layer on the surface and a tough tear resistant label paper as the base paper;
Three proof thermal paper mainly has waterproof, oil resistant, scratch resistant properties, and can be stored for a long time, about 2 years. Scratches are not obvious when scratched with nails. Three proof thermal paper adhesive labels are widely used in fields such as shopping mall, supermarket electronic scale paper, clothing, international logistics, etc.
What is Blue Grid Thermal Paper Adhesive?
Blue grid thermal paper is actually a thermal paper adhesive with a blue grid substrate. In addition to blue grid substrate, there are also white grid substrate, white thick substrate, etc. Today we will learn about the advantages of Blue Grid, as follows:
Blue grid and white grid are both types of Grassin base paper, with only different colors and the following characteristics:
1. The paper has a uniform texture and strong transparency
The best Gracin paper has a tight and uniform texture, and its transparency is particularly strong, much stronger than traditional glass paper. Therefore, it is also very popular among people and is often used in the production of barcode labels and raw materials for products such as tape, and is also suitable for rotary or flat die cutting
2. High temperature resistance and good moisture and oil resistance
Grassin paper has a unique feature of high temperature resistance and good moisture and oil resistance. This type of paper is widely used as a raw material for packaging in the food and pharmaceutical industry, playing a role in waterproofing and oil resistance. It is different from ordinary paper and has certain functional characteristics, which can meet some high demands of customers
3. The strength inside the paper is high
Grassin paper is mainly used as release paper for adhesive tapes and dressings in medical products because of its high internal strength. The paper processed from this type of paper naturally has sufficient strength and can also have a durable effect. Increasing its service life can also be considered as cost saving and improving its cost-effectiveness.
