Two posters are now available from this company for technical use: a color theory poster and a viscosity conversion chart. The color theory poster displays color measurement of solid colors and color measurement of effect finishes, including tolerance graphs, equations, and special effect images of sparkle and graininess.

The viscosity conversion chart poster compares the efflux times of the BYK-Gardner Zahn cups, S90 Signature Zahn cups, EZ Zahn cups, Ford cups, Din Cup 4mm, and ISO cups. The poster also includes instructions for using the chart, standard methods, specifications, viscosity equations, centistokes vs. efflux time, and suggested standard oils for each cup.
