The international standard ISO 3664:2000 has redefined the viewing conditions for the Graphic Arts and Photography Industry.
These strict requirements cannot be met by using generic fluorescent tubes or fixtures.


JUST Normlicht
has not only met the ISO 3664:2000 specification but has exceeded the standard.

JUSTNormlich Daylight 5000 proGraphic fluorescent tubes however comply with all criteria of the standard:
  • Color coordinates, defined as x = 0.3478 and y = 0.3595,tolerance allowed only 0.005°.
  • Color temperature 5000 Kelvin(D50), mandatory for allprepress and press activities.
  • Color rendering value Ra > 90. - CRI - JUSTNormlich Daylight 5000 proGraphic fluorescent tubes CRI = 95,6
  • a luminance level of 2000 Lux (+ / - 250 Lux) on the viewing surface
  • an even distribution of the light and a glare and shadow free viewing environment.
According to ISO 3664:2000, the color rendering value (CRI) is derived from 8 test colors. This being a relatively small sample JUST daylight 5000 proGraphic tubes are further tested from 215 colors. Even here JUST daylight 5000 tubes meet a value of CRI215 = 95.6, which is above any of the values set by common industry standards.
To determine the maximum metameric error, the ISO 3664 : 2000 specifies the metamerism index of a viewing booth for the visible spectrum with a value MI(vis) < 1,0 and for UV the MI(uv) < 4. The next version of the ISO 3664 the value for the MI(uv) is decreased to < 1,5. Just Normlicht products are already achieving this future requirement.




Control Station CtP Pro


The Control Station CtP Pro makes spot checks of CtP- and conventional Offset Plates more efficiently and safely.
Today, quality control becomes
much more important during all digital prepress steps, especially with the process of computer to plate. The printing plate is the last and sometimes the only visible hardcopy that can be checked before starting the printing press.

- Comes with an asymmetrical proof light for even illumination of the plate
- Vertical control panel allows comfortable and easy positioning of plates
- Magnifying glass with comfortable hand rest support
- Magnifying glass moves smoothly in vertical and horizontal directions
- Manual height adjustable plate board for comfortable working in upright position
- Adjustable slanted plate board can be used for color matching of press sheets under standardized lighting conditions.
