While not at NAB we wanted to include our friends at DSC labs. Last year after NAB they made a change to their printing substrate moving to the use of new AcuFlect 3 media.
AcuFlect 3 while less reflective than the original AcuFlect Glossy, still maintains the dynamic range and color saturation that have made the original charts legendary.
Why did they do this? After testing of a variety of different materials, customers reported back that setting up the charts was much easier under multiple different light sources, saving time and making the camera reference process go faster. As a bonus, the new AcuFlect 3 surface can be wiped down with a damp cloth and has the added benefit of being more Eco-friendly.
