In a perfect world, you should be able to put ink in the press, run a job, and achieve color consistency. Unfortunately, every year flexographic and gravure printing operations waste ink, substrate, and press time trying to get color right.    Although advancements in technology have made it easier to achieve color accuracy, the variables that affect color still exist. In this three part series we’ll share over two dozen reasons your color might be wrong at press side. Today&rsqu...

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...

Pour mesurer la couleur, un dispositif de colorimétrie éclaire un échantillon, capture la quantité de lumière transmise ou reflétée dans la plage de longueurs d’onde de 380 à 780 nm et la quantifie en mesure spectrale. La colorimétrie est nécessaire pour spécifier, quantifier, communiquer, formuler et vérifier la qualité des couleurs pour des travaux dans lesquels celles-ci constituent un critè...

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...

Especially in the print industry, checking color quality at multiple steps along the way is the key to ensuring you’re on the right track. Without print color management, you can end up producing something you think is right, but is completely wrong in the end. Managing color in the pressroom closes the gap between expectations, press operators, specifications, and color to ensure good quality.  During design, it means accurately specifying colors for reproduction on the ...

As brand owners compete to make packaging stand out, commercial and flexible packaging converters and label printers are charged with achieving accurate color – on unique substrates – with shorter print runs. Many spend a lot of time mixing ink, then end up throwing it away when the color isn’t right. Others mix ink, store it, and spend way too much time trying to reuse it for future print runs.  If you’re stuck in this cycle, you’re essentially paying for ink...
