1. Watermark

Watermark
          face side                    reverse side

The watermark is clearly visible when the banknote is held against the light. A “localised” stepped watermark (i.e. a combination of positive watermarks – visible as dark areas – and negative watermarks – visible as light areas – with various shades between the darkest and lightest parts) is used. The watermark is located in the middle of the wide unprinted margin and consists of the portrait of Charles IV as depicted on the banknote. The 2018 version also contains a negative (white-line) 100 with a stylised royal orb. When viewed from the face side of the banknote, the watermark is mirror reversed relative to the printed portrait.

2. Windowed thread with microtext

Windowed thread with microtext

    face side              through-view

The windowed thread is a strip of metallic plastic embedded into the paper of the banknote. It is 3 mm wide with the recurring hatched negative microtext “ČNB 100 Kč”. On the banknote’s face side it protrudes from the surface in four places. When the banknote is viewed, only the protruding part of the strip on the face side is visible. When viewed against the light, the whole strip is visible on both sides as a continuous dark line with the microtext “ČNB 100 Kč” showing through. The protruding parts of the strip change colour from puce to green when tilted.

Coloured fibres

Orange fibres, 6 mm long, embedded in the paper and visible to the naked eye. They can best be seen on the white unprinted margins of the banknote.

4. Front-to-back register

Front-to-back register CR

      face side               reverse side              through-view

On each side of the banknote only a portion of this mark is visible. The complete mark, with precisely matching individual lines, is visible when the banknote is viewed against the light. On the 1995 version, the front-to-back register is a circular mark created by the letter “C” with an interposed letter “S”. On the 1997 and 2018 versions, the front-to-back register is a circular mark in the form of the letters ČR, which overlap and complete each other against the light.

5. Latent image

Latent imager

The latent image becomes visible only when the banknote is tipped horizontally at eye level and held against a light source. It consists of figures indicating the banknote’s denomination. When the banknote is looked at transversally (the long side nearer the eyes), a positive (dark) pattern is visible, and when viewed longitudinally (the short side nearer the eyes), a negative (light) pattern is visible. The latent image is located on the banknote’s face side in the decoration on the portrait’s shoulder.

The basic microtext is concealed in the strip of basic colour near the right-hand white margin to the right of the portrait on the face side, consisting of figures indicating the banknote’s denomination. On the reverse side, microtext is also concealed in the strip of basic colour between the state symbol and the right-hand margin, consisting of words indicating the banknote’s denomination.
