The International Standards Organization has defined ISO 12647 as a set of Graphic Arts standards for printing. Included are eight parts: Part 1: Print parameters and measurement methods Part 2: Offset lithographic processes Part 3: Coldset offset lithography on newsprint Part 4: Gravure printing Part 5: Screen printing Part 6: Flexographic printing Part 7: Proofing processes working directly from digital data Part 8: Validation print processes wo...

To measure color, a color measurement device shines light onto a sample, captures the amount of light that is transmitted or reflected in the 380 nm to 780 nm wavelength range, and quantifies it as a spectral measurement. Color measurement is necessary to specify, quantify, communicate, formulate, and verify color quality for color critical work. Because everyone perceives color differently, color measurement is more precise than visual evaluation. What is a Color Measurement Device? There are t...

Learn more about light, reflection curves, optical brighteners, and more. Illuminants Electro magnetic radiation in the wavelength range from 380 nm to 730 nm is seen as light by our eyes. Low wavelengths show as blue light. Then the spectrum continues from green, yellow, orange to red. UV radiation is located in the range below 380 nm; the range above 730 nm is called infrared radiation. The visual impression of a colored body changes by the composition of the incoming light. ...

Surface appearance can change your perception of color. Think of a glossy magazine. If the light is shining directly on the page, you may need to tilt the magazine and change the reflection angle to clearly see the colors. Likewise, a textured surface may appear to be a different color than a smooth surface of the same object. Since spectrophotometers determine a color’s spectral values by shining light onto the surface and measuring the reflectance, choosing the right instrument an...

COVID-19 has forced many companies to rethink the way they communicate, approve, and produce color. For some, that means trying to conduct “business as usual” from a remote location. For others, it means finding ways to manage color without travel. Either way, we know our customers are doing everything they can to sustain business while keeping their employees healthy and safe. We want to help. Over the past few months we’ve been adding new resources t...

2020 has definitely been a year for the record books. As many of you looked for new and creative ways to work, we tried to support you with learning resources. Today we’re looking back on the topics that captured the most attention this year. From the basics of color science to choosing the best color measurement instrument for your needs (and learning how to use it), here’s what captured our Learning Resource Leader Board for 2020. Top 10 Learning Resources of 2020 #1 &...

Black Friday. Not only is it the much anticipated start to holiday shopping, it’s also a day manufacturers have been preparing for all year long. Whether mass-producing holiday cards, candy canes, plastic toys, or festive clothing, accurate color is a must. Manufacturers can’t ship two of the same toy if they won’t match on the showroom floor, and holiday sweaters that are a shade off will end up at a discount store instead of a fashion boutique. Perfection is especially import...

Like the additive color model, subtractive color mixes wavelengths of light to produce what we perceive as color. However, the subtractive model uses pigments or ink to block – subtract – light rather than adding it. Combining two pure additive primaries produces a subtractive primary. The subtractive primaries of cyan, magenta, and yellow are the opposing colors to red, green, and blue. Cyan is opposite Red Magenta is opposite Green Yellow is opposi...

Recently we had the opportunity to sit down with Laura Guido-Clark, a consumer products designer of color, material, and texture. She has been dubbed an “Experience Consultant,” which reflects her interest and study of human reactions to the look and feel of new products. Photo by Laura Flippen. We asked Guido-Clark to speak with us because we also appreciate the importance of color in our lives. Q. What inspired you to pursue a career in color? A. When I wa...

A calibrated display is not just for photographers. If you browse inspiration photos online, send color samples back and forth via e-mail, or transfer color files between suppliers and customers, you need to calibrate and profile your display to trust the colors you see on-screen. When talking about monitor calibration, many people interchange illuminance, luminance and brightness, but they are not the same. Here are the differences you need to understand to properly calibrate and...
