En un mundo perfecto, se debería poder poner la tinta en la impresora, ejecutar un trabajo y lograr la consistencia del color. Desgraciadamente, cada año las operaciones de impresión flexográfica y de huecograbado desperdician tinta, sustrato y tiempo de impresión tratando de conseguir el color correcto. Aunque los avances tecnológicos han facilitado la precisión del color, las variables que afectan al color siguen existiendo. En esta serie de tr...

La apariencia de la superficie puede cambiar su percepción del color. Piense en una revista con brillo. Si la luz brilla directamente sobre la página, es probable que deba inclinar la revista y cambiar el ángulo de reflexión para ver claramente los colores. De igual manera, una superficie texturizada puede parecer de un color diferente al de una superficie lisa del mismo objeto. Dado que los espectrofotómetros determinan los valores espectrales de un color ilu...

La COVID-19 ha paralizado a muchas industrias, las textiles incluidas. Las prohibiciones de viaje y las órdenes de refugiarse en un lugar están obligando a las grandes cadenas interconectadas a repensar su forma de trabajar. Para las marcas que ya estaban buscando nuevas formas de lograr un color preciso y acelerar el tiempo de comercialización, esto podría ser una oportunidad. Esta pandemia global podría ayudar a la industria de la vestimenta a tomar decision...

Reflective surfaces and metallic inks are very popular for printing and packaging applications. Consumers love the look; but for printers, these substrates and inks are expensive and make color control a challenge. Today we’re taking a look at the measurement options available for controlling these very marketable print and packaging applications to help printers and converters meet brand owner expectations and maintain the highest possible quality output. Sphere vs. 45°:0° - ...

The two most common spectrophotometers are the 0:45 and the sphere (aka diffuse/8°). We get a lot of questions about which is the best choice. Here’s the difference in how these two devices measure color, and guidelines for when to use each. 0:45 In a “fixed geometry” or “single angle” device, the first number is the starting point of the light, and the second number is where the light ends up after the reflection off the surface of the sample. In a 0:45 ...

The World Series starts next week. While players and fans are gearing up for the big event, stadium groundskeepers are preparing, too. You’ve surely seen those meticulous patterns in the grass – crisscross, spiral, plaid – but do you know how the groundskeepers create them? Thanks to a phenomenon called geometric metamerism (aka gonio-appearance), the grass really is greener on the other side. Read on to learn more about this optical illusion that can trick your eyes and wreak havoc on y...

Have you ever sent out a job that passed your inspection, only to have the customer reject it for out-of-tolerance color? You recheck the data and the instrument says the color passed the agreed tolerance… why is the customer saying it doesn’t? We get a LOT of these conflicting measurement calls in technical support. The solution is simple – document a color control program that clearly defines how to assess color, then make sure everyone (including your customer) follow...

No matter what you’re manufacturing, taking spectral measurements will help ensure your color remains accurate and consistent throughout your production run. When choosing the best spectro for your needs, your first consideration should be the type of surface you’ll be measuring. Measuring reflective surfaces poses a challenge because the effect of gloss can actually change the color appearance of a sample. The surface reflection of light is what causes the gloss effec...
