Instrumental color (i.e. L*A*B*) and optical density measurements were performed on coated and uncoated papers printed with water based inkjet inks using continuous binary array inkjet equipment. Lightfastness tests were performed in a QUV test chamb...

Sunlight is an important cause of damage to materials exposed outdoors. The shorter the wavelength of sunlight, the greater the damage. The shortest wavelengths in sunlight are the ultraviolet. Although ultraviolet light makes up only about 5% of the...

This paper is intended as a general introduction to cyclic corrosion testing (CCT). It outlines the rationale for cyclic testing, includes some guidelines for using cyclic tests and explains some common CCT cycles and their applications. This discuss...

Outdoor exposure racks and accelerated chambers are the two main methods for testing materials for weathering durability. In the fast paced current world, time constraints have determined that outdoor weathering exposures take too long to provide the...

In the 1980s, damage to automotive coatings from acid rain became a problem. Both dealerships and buyers complained about the ring type or “water spot” etches that were caused by acid catalyzed hydrolysis in areas where acid rain occurred and tempera...

How can you know whether an ink will remain fade resistant under the variety of lighting conditions that it may encounter during its service life? What is the cost of product failure? What is the price/performance trade-off between affordability and ...

Artificial weathering plays an important role in the development of improved coating systems by providing a means of obtaining performance assessments in much shorter time than it is possible using natural weathering. However, there exists at present...

The popularity of personal computers and digital cameras has ushered in an exploding new market of digital images printed from consumer printers. There is an endless combination of ink jet inks and commercial photo papers currently available in the m...

Why should you test products for lightfastness and weatherability? Ian Johnston, director of research and development for Inkware LLC sums it up in a sentence: “It helps us to sleep better at night.”Download File

It is widely accepted that improved methods for assessing the corrosion controlling properties of organic coatings on steel are needed. Difficulties with established testing procedures (primarily ASTM B 117 salt spgy) have been well documented]-3 and...
