The production of printed patterns is to print design patterns, photos, text information, etc. onto the substrate, making it a completely independent product for circulation, such as labels. There are many ways to print labels. This article mainly introduces transfer printing labels, that is, physical and chemical methods to transfer printed patterns and colors onto substrates. The application characteristics and methods of printing products have many the difference.
Stamping transfer label
1. Features and uses: Suitable for hard, smooth materials such as paper, wood, plastic, etc., used in art design, photo albums, toy stickers. Scratch, transfer paper, etc.
2. Usage: Uncover the surface of the label from the release paper, align the pattern with the position to be transferred, and evenly rub the back surface of the pressure sensitive film with nails or wood chips, and tear the transparent film to complete the transfer of graphics and text.
Reverse pressure transfer label
1. Features and uses: The reverse pressure-sensitive transfer label is divided into three types: solvent-resistant, scratch-resistant, and baking-resistant. Solvent-resistant pressure-sensitive transfer label after solvent-resistant scrubbing; scratch-resistant pressure-sensitive transfer label can be processed without any treatment after transfer, which can have good adhesion and scratch resistance, but avoid hard objects Scratch; high-temperature baking type pressure-sensitive transfer label can be baked after transfer, or directly baked without spraying oil. The pressure-sensitive transfer label is suitable for hard materials such as metal, plastic, synthetic materials, such as air conditioners, refrigerators, washing machines, water heater casings, fishing rods, clubs, bicycles and other sports equipment surface decoration.
2. Usage: Just peel off the protective film, align it with the transferred position, evenly squeeze and tear the bottom paper to complete the pattern transfer.
Reverse water transfer label (B, C transfer label)
1. Features and uses: The so-called B, C transfer mark, that is, the reverse transfer pattern needs to be transferred by means of B, C transfer liquid, can be applied to bicycle frame, car shell, fishing rod, wood. Smooth surface such as metal.
2. Usage: Soak the water transfer label paper in B and C liquid for about 6 seconds, remove it and stick it on the surface to be printed, use rubber strip to evenly scrape on the back of the paper, scrape the water in the middle, and then use water. When wetted, the liner can be torn and the pattern transferred to the substrate. Wipe off the water left on the surface of the substrate with a clean, damp cloth. After drying thoroughly, spray the varnish and bake. Because of its anti-adhesive surface, it is generally applied to products with relatively regular surfaces.
Soluble forward water transfer label
1. Features and uses: The so-called soluble water transfer printing label, that is, the water transfer paper which functions as film forming and bridging, can be compatible with transparent varnish during post-treatment, leaving no trace, can be used for helmet , bicycles, cars, all kinds of rackets, clubs, toys, musical instruments, small furniture and other materials surface.
2. Usage: Cut the label pattern, immerse in warm water of 25-40 °C for 30-60 seconds, remove the transfer paper and stick it on the surface of the substrate, and the pattern can be slid on the paper. Has been separated from the liner. After cleaning the surface of the object with water, the rubber under the layer is evenly scraped with a rubber strip to make the pattern flat on the surface of the material. Finally, the water is wiped off with a clean cloth to complete the transfer of the pattern.
Since the graphic film layer has a certain toughness, when the moisture under the layer is scraped, the pattern is attached to the irregular surface while wiping the water, which is also the biggest advantage of the water transfer method. After the drying is sufficient, the transfer image can be sprayed with varnish and baked. Be sure to dry thoroughly, otherwise bubbles will appear after baking, resulting in waste. The water transfer label is characterized by beautiful printing, bright colors, wide application materials, strong and beautiful labels, and is not easy to change color, especially for irregular surfaces.
Strippable type water transfer label
1. Features and uses: The peelable film type forward water transfer mark means that the water transfer film which functions as a film forming and bridging can be peeled off during the transfer process, and the ink layer of the pattern adheres to the material after transfer. On, to achieve the effect that direct screen printing can not achieve. Widely used in ceramics, glass materials, gifts, bicycle racks, motorcycle baffles, packaging containers, helmets and other irregular surface decoration.
2. Usage: The label is cut and immersed in warm water of 25-40 ° C for 30-60 seconds, and the transfer paper is taken out and attached to the surface of the substrate; the pattern can be slid on the paper surface, that is, after being separated from the attached paper. Clean the surface of the object to be attached, press the pattern to pull out the bottom paper, and stick the pattern to the surface of the substrate; use a rubber strip to evenly dry the moisture under the layer, so that the pattern is applied to the surface of the substrate in a flat manner, and then the cloth is cleaned. Dry the water and the pattern transfer is complete. Dry at least 1 hour after transfer. For plastic, wood and other products, apply varnish after stripping. Good results can be achieved by baking at 800 ° C for 10 minutes or at 180-200 ° C for 15-20 minutes. This method is applicable to glass and ceramic products, also known as glass and ceramic low temperature water transfer labels.
