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 # |
|---|---|---|---|---|
| Medium | 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.
