These notes are like the preceding issues, but with upgraded security features. Specifically, the 20-, 50-, and 100-kwacha notes have a SPARK Live feature added at lower right front and a 5-mm wide windowed security thread. The 10-kwacha note has a new windowed security thread, and the 2- and 5-kwacha notes have different images in glossy varnish with blind embossing. All denominations have tactile diagonal lines for the visually impaired intaglio printed at center left and right front. The 5-, 10-, and 20-kwacha notes also have new printer imprints at lower right back.Courtesy of Andrew Roberts.
