Color Management Technology Sharing | What is a spectrophotometer/spectrometer? (Part 1)

A spectrophotometer is a color measurement instrument used to capture and evaluate color. As part of a color control program, especially in global and distributed environments where components are manufactured in different locations and assembled together as a whole, brand owners, designers, suppliers, and manufacturers use spectrophotometers to specify and communicate color, and manufacturers use them to monitor color accuracy throughout the production process. Each physical sample has its own reflectance, or the amount of light reflected, and transmittance, or the amount of light absorbed. A reflectance spectrophotometer emits a beam of light and measures the amount of light reflected from different wavelengths of the visible spectrum, while a transmittance spectrophotometer measures the amount of light that passes through the sample. Spectrophotometers can measure and quantitatively analyze almost anything, including liquids, plastics, paper, metals, fabrics, and painted samples, to verify color consistency from conception to delivery.

Color Management Technology Sharing | What are the different types of spectrophotometers

A spectrophotometer is an instrument that measures color by shining a beam of light and capturing the amount of light that is reflected or transmitted to quantify color. Spectrophotometers can provide color data for virtually any sample, including liquid, plastic, paper, metal, fabric, and paint samples. Spectrophotometers are used in every industry that requires accurate color. From packaging to textiles to beverages and plastic parts, these devices help ensure that the color produced matches the color originally specified.

Color Management Sharing | Why is there a "color difference" between design and print?

Color difference refers to the difference in color perception between two samples, including differences in lightness, chroma, and hue. A color difference formula is used to calculate the difference between two colors after measuring them with a colorimeter. A visual assessment method involves placing two samples side-by-side under specified lighting and viewing conditions for human visual comparison. Visual estimation determines the difference and direction between colors, but not the grade difference. If color difference can be represented by the distance between two points, it achieves numerical expression. Colorimetry is commonly used to determine the difference between colors.

Technical Sharing | Optical Brightener Compensation (OBC)

What is Fluorescent Whitening Agent Compensation OBC? Whether you are a photographer printing works to be hung in an art gallery, or a professional printer producing billboards, packaging, related materials, or other commercial items, the use of fluorescent whitening agents in paper may lead to color casts, difficulties in chasing samples, and inconsistencies in color. However, these phenomena are often related to fluorescent whitening agents. With Keyin Technology's color management solution, you can easily correct this phenomenon and generate and display colors as you wish. Paper manufacturers often use fluorescent whitening agents to make yellowish paper appear whiter and brighter to the human eye.

Technical Sharing | Interpretation of Color Control Standards for Tobacco and Alcohol Packaging Printing

The appearance of cigarette pack printing is exquisite, especially the packaging of high-end cigarettes. This is due to the use of unique printing materials and printing technologies. The main characteristics of cigarette pack products are large areas of solid color blocks and spot color printing, requiring thick ink layers, high color saturation, and vibrant colors. How to ensure that such high-saturation colors are accurately and consistently achieved on the cigarette packs?

Technical Sharing - Error of the Same Model Colorimeter

When visually evaluating colors, people rely on their color perception skills to determine color matches. In the production process, this subjectivity can lead to confusion and failure among customers, suppliers, production, and management. Therefore, color measurement equipment is crucial for many industries. Using a spectrophotometer to measure colors allows for the communication and comparison of color data, leading to precise results.
