SKZ is proud to be a supplier of color measurement instruments to The Coca‑Cola Company – a Fortune 500 leader that demands nothing less than perfection. For a brand built on recognisable red and consistent product appearance, colour accuracy is as critical as taste. We thank Coca‑Cola for selecting SKZ among numerous instrument manufacturers. Every year, we deliver SKZ3020 portable spectrophotometers to their bottling plants and packaging facilities worldwide, each backed by our dedicated after‑sales support. As their production footprint expands, order volumes continue to rise – yet our commitment never wavers: reliable performance, affordable excellence, and service that turns every purchase into a lasting partnership. Our latest shipment went out in early 2026, and many more are on the way. Together, we’re safeguarding brand identity – one measurement at a time.
Coca‑Cola’s iconic red is instantly recognised across cultures, but maintaining that exact shade across millions of cans, bottles, labels, and caps is a huge challenge. Variations in printing inks, substrate materials, or coating processes can cause unacceptable deviations. Even minor colour shifts can weaken brand perception or lead to product rejections. That’s why Coca‑Cola’s quality control teams rely on precise, portable colour measurement tools to verify every batch – ensuring that the red you see in Tokyo is identical to the red in New York. The SKZ3020 was chosen for this mission because it delivers laboratory‑grade accuracy in a handheld, rugged design, perfectly suited for both factory floors and remote warehouse inspections.
The SKZ3020 is a horizontal portable spectrophotometer designed as an economical yet highly capable entry‑level instrument. It is available with either a 4 mm or 8 mm measurement aperture (single aperture per unit), allowing customers to choose the best fit for their sample size – whether measuring tiny bottle caps or large label panels. Its core optical engine features a full‑spectrum LED light source, which provides stable, broad‑spectrum illumination for accurate colour evaluation across all visible wavelengths. This ensures reliable readings even on challenging surfaces like metallised films or glossy coatings.
Repeatability is the bedrock of quality control. The SKZ3020 achieves a repeatability precision of less than 0.07 ΔE*ab (standard deviation) on white tiles, meaning that repeated measurements of the same sample yield virtually identical results. This level of consistency gives Coca‑Cola’s inspectors the confidence to pass or reject batches without second‑guessing – reducing waste, saving time, and maintaining production efficiency. When you’re processing millions of units daily, every 0.01 counts.
The SKZ3020 is equipped with a visual positioning system that projects a target spot on the sample surface, ensuring that the measurement area is exactly where the operator intends – especially useful for small or curved objects like caps and rims. This eliminates guesswork and improves measurement repeatability across different operators. Additionally, the instrument supports SCI (Specular Component Included) mode, which measures total colour including both reflected and specular light. This mode is essential for evaluating gloss‑coated or metallic surfaces, giving a reading that closely matches what the human eye perceives under normal lighting – critical for final product appearance approval.
Despite its economical price point, the SKZ3020 does not sacrifice durability. Its horizontal, ergonomic design fits comfortably in hand, and the intuitive button interface allows one‑handed operation – ideal for rapid spot checks along high‑speed production lines. The device is powered by a rechargeable battery with extended operating time, and its robust housing withstands the occasional bump or drop in busy facilities. With simple calibration using standard white and black tiles, routine maintenance is quick and hassle‑free, minimising downtime.
At SKZ, we believe that a great instrument deserves great support. Every SKZ3020 delivered to Coca‑Cola comes with a comprehensive calibration certificate and access to our technical helpdesk. We provide regular firmware updates and responsive repair services, ensuring that each unit remains accurate over its lifetime. As Coca‑Cola’s needs evolve – whether new packaging lines or stricter colour tolerances – we stand ready to adapt our solutions. This is the SKZ promise: not just selling tools, but building relationships that last.
Our collaboration with Coca‑Cola is a testament to the trust that a global leader places in SKZ. With each new shipment, we reaffirm our dedication to quality and customer satisfaction. The SKZ3020 may be our “economy” model, but its performance and reliability are anything but basic – it’s the smart choice for companies that demand accurate colour control without overstretching their budget. Together with Coca‑Cola, we are ensuring that every can, every label, and every package tells the same vibrant story – one measurement at a time.
