In the fiercely competitive packaging and labeling industry, print quality has become a vital tool for businesses to build brand image and attract consumer attention. Eye-catching packaging and exceptional print effects not only enhance product value but also directly influence consumer purchasing decisions.
However, printing on dark substrates often presents significant challenges for printing companies.
On materials like black PET or aluminum foil, printed designs tend to appear dull, unclear, and lacking in saturation, severely affecting overall product appearance and perceived quality.
To address this industry pain point, StarColor, backed by years of technical expertise and continuous innovation, has launched a breakthrough solution—High Opacity UV Flexo Inks, bringing new possibilities to flexographic printing.
StarColor’s High Opacity UV Flexo Ink is a UV-curable ink formulated for superior opacity. It overcomes the limitations of traditional inks through advanced formulations and optimized manufacturing processes, effectively covering dark-colored substrates to ensure vivid, sharp designs.
In real-world applications, the ink demonstrates strong adaptability across various materials such as labels, plastic films, and metallic foils. Whether it’s small, delicate product labels or large-format flexible packaging, StarColor’s high-opacity UV flexo ink delivers flawless performance across a wide range of printing needs.
One of the standout features of StarColor’s ink is its superior coverage. While conventional inks often require multiple layers to mask dark backgrounds, StarColor’s advanced formula ensures full opacity with just a single print pass. This not only saves time and reduces ink consumption, but also improves production efficiency and cuts costs.
Case Example:
A label printing company previously needed 4 passes to print on black PET labels, resulting in a 2-hour production cycle. With StarColor ink, only 1 pass is required, cutting the production time to just 30 minutes—a 4x efficiency boost.
In addition to its opacity, the ink boasts high color density, accurately reproducing artwork with vivid, full-bodied hues and enhanced depth. For premium cosmetic packaging, this results in luxurious, high-definition prints that strengthen brand identity and consumer appeal.
Printing products must endure harsh conditions such as friction, moisture, and heat. StarColor’s ink offers strong adhesion and excellent wear resistance, ensuring prints remain intact and vibrant even after prolonged use or frequent handling.
This makes it ideal for high-durability labels in sectors like food & beverage and industrial labeling, where long-term clarity and legibility are critical.
Speed is essential in modern printing. Thanks to advanced UV-curing technology, StarColor’s ink dries instantly, increasing press speed by 30%–50%. It’s the perfect solution for high-volume production environments.
As environmental standards become more stringent, StarColor remains committed to sustainability. Its UV flexo ink uses a low-VOC formula, minimizing harmful emissions and promoting a healthier working environment.
The ink complies with major global standards, including EU REACH and US ASTM, supporting businesses in their move toward green, compliant production.
For labels on black PET, aluminum foil, or other dark materials, StarColor’s ink ensures crystal-clear text and graphics. It’s especially valuable in high-accuracy fields such as pharmaceuticals and electronics, where legibility and precision are critical.
High-end beauty brands demand impeccable packaging. StarColor’s high-opacity UV ink enhances product aesthetics with its brilliant color reproduction and fine detail, conveying luxury and sophistication in every print.
Labels in this sector must withstand friction during transport and retail handling. StarColor’s ink resists abrasion effectively, keeping bottle and can labels legible and vibrant throughout their lifecycle.
One renowned label manufacturer struggled with poor results when printing on black PET, leading to a 15% complaint rate due to dull, unclear graphics. After switching to StarColor’s high-opacity UV flexo ink, single-pass printing became possible. The result: bold, vibrant colors and a complaint rate below 3%.
