Please note that in 2013, the Skype Specification was revised. In this revision the surface type of the test charts has been changed from Semi-Gloss/Luster to Matte, as a measure to reduce specular reflection. The table below indicates the model numbers for the legacy charts, and the corresponding model numbers for the new matte surface charts.
|Chart Size||Paper Size||Active Area||Legacy Model #||Current Model #|
|Small||24″ × 34″||22″ × 33″||SP01152||SP00128|
|Large||44″ × 60″||40″ × 59″||SP09344||SP08320|

Lighting Setup for ITDR-36
As written in the specification, “This chart needs an uniform light emitting surface below the chart, such as a dedicated light box.” For this purpose we recommend the GL-16E Lightbox Viewer. This lightbox provides even illumination and features a high frequency ballast to eliminate flicker.
