                         Colors in map designing and pre-publishing process

n      100% cyan for Hydrology

n      20, 30, 40% S -- water areas -- see and oceans

n      1,2,3 colors of  CMYK -- area color

n      > 5% for every color

n      Clean colors (without black - K)



                                            CONCLUSIONS

n      Dimensions for color defining -- independent of color monitor and possibilities of print or
publishing machines.

n      Traditional rules for map coloring could be kept.

n      Some limits in publishing process should be take into account in the first steps of map
designing

n      Unification of the colors could be lead to their standardizations.

                                         for your attention
