White ink can provide opacity and white primer for labels printed on transparent, metallic and similar substrates. It is usually printed on the surface of the substrate, immediately before the use of colored inks.
White ink printing transparencies
When printing on transparencies, white ink is often used to provide an opaque surface for logos, barcodes, ingredients, and nutritional information. White ink can also be used to create a "window" on a clear label to display the product in a clear container, or to focus the customer's sight on a certain position behind the label.
White ink printing metal film
When printing on metal films, white ink is most commonly used to weaken the metallic luster of the substrate. Certain artistic elements on the metal substrate are printed without the use of white ink to create the appearance of non-ferrous metals. When using white ink, the metallic luster is weakened and the appearance is similar to non-metallic film or paper. Colored inks will form metallic tones on the surface of the film. Accurate spot color matching on transparent and metal substrates requires a layer of white ink under the color ink. If there is no white ink layer, the color of the stain will change due to the light reflected or transmitted by the substrate.
White ink printing on white film
When printing on white film, white ink and digital varnish can be used to create raised surfaces and textures. White ink, color ink, and digital varnish can be used to elevate the texture above the area where only color ink (or no ink) is printed.
Vivid white: an inkjet printer that can print the brightest digital white UV ink on the market
China's TUHUI inkjet printer company recently launched the UV inkjet printer market that can print the brightest white ink: TUHUI White dtf printer machine.
Vivid white is a kind of print that is highly regarded by the market. The TH-602 DTF printer, the latest product of the TUHUI brand UV ink series, reproduces the brightest white in the industry. Based on decades of experience, after thorough and rigorous testing, TUHUI has created an ideal printing solution that can print bright white on dark substrates. Vivid white can also serve as an opaque white background for multi-color graphics to enhance the colors of artworks and make them appear more vivid. The advantage of this is to ensure that the color matching of all products is consistent-the opaque white will make the true color appear on the dark substrate.
Like all UV ink series colors, bright white has excellent adhesion and, like other products in the product series, achieves the same strict adhesion and compliance standards. A distinctive feature is that vivid white is the pour point of printers that use TUHUI ink, which eliminates the trouble of flushing the machine when customers switch to this white ink. It can also be used for other printers that need to improve the white opacity.
Vivid white is very suitable for various substrates, including stainless steel, coated metal, plastic, etc. It can also print on various flat and cylindrical objects. Applications include beverages, injection molded enclosures, promotional items, electronic products, etc.
"For high-quality graphics, bright white makes everything different. We have been looking for the ideal pigment combination for many years to provide excellent white opacity and easy jetting. The CEO of TUHUI said: "Our newly launched TH-602 DTF printer machine does have obvious changes. After extensive testing, we think it is the brightest white ink on the market.
