Specs say no wood base. Is this a matt RC poly based media? How's the residual curl? Thanks
Curl seems as you'd expect ie better than before because of the larger core. Where did you get the idea it isn't wood based? Specs lifted from my supplier website are very similar to the old stuff (although they have changed the test method for brightness & opacity) except whiteness which is up from 75 to 95:
Core Size - 3" (75mm)
Thickness - 12.1 mil / 307 microns per ISO 536
Brightness - 95% per TAPPI T-452 Test Method
Weight, Metric - 269 g/m2 per ISO 536 Test Method
Opacity - Greater than 98% per TAPPI T-425 Test Method
Whiteness - 95 per ISO 11475 Test Method
Country of Origin - Made in Germany
Gloss Level - Matte
Primary Material - Wood fiber
