The process according to claim 9, wherein the isolation dye applied in the isolation dye printing step contains aqueous polyurethane dispersion systems and/or barium titanate (BaTiO2), said dye having a dielectric constant which is raised by said dispersion systems and/or BaTiO2. 12. The process according to claim 9, wherein EL substances printed in the EL substance printing step consist of multi-colored electroluminescent pastes to which "range spacers" are added, if needed, thereby forming microencapsulated light pigments, said spacers preventing the microencapsulated light pigments from being damaged by the high pressures during printing. 13. The process according to claim 9, wherein after the EL substance is printed in the EL substance printing step, translucent dyes are printed above or below the EL substance to achieve additional graphical and security structure. 14. The process according to claim 9, and comprising the further step of applying a thermal press at temperatures up to 200° C. and pressures up to 500 N/cm2after the last process step to stabilize and improve the quality of the security document. 15. A testing device to visually and/or machine test the authenticity of value/security documents that have EL-active security features at certain points thereon, said features containing electroluminescent substances, the testing device comprising: two supports on the testing device parallel to one another between which the document to be tested is placed, at least one of said supports being transparent; an electrode arrangement on at least one of said supports, said electrode arrangement being capable of producing an alternating electric field that penetrates the value/security instrument at least at those points where the EL-active security features are located, thus exciting the EL-active security features so that they emit photons that can be evaluated either visually or by machine. 16. The testing device according to claim 15, wherein both electrodes are located on one side of one of said stationary supports in the form of a common electrode arrangement. 17. The testing device according to claim 15 or 16, wherein said electrode arrangement is essentially planar with electrodes located in approximately the same plane and lying adjacent to one another that form a field gap between each other, wherein the EL-active security features are penetrated by the field lines of the alternating electric field produced in the field gap. 18. The testing device according to claim 17, wherein said electrode arrangement consists of electrode fingers that mesh with one another, said electrode fingers forming a meandering field gap between each other. 19. The testing device according to claim 15 or 16, wherein said electrode arrangement is applied onto an isolation layer. 20. A testing device to visually and/or machine test the authenticity of value/security documents having EL active security features at certain points thereon, said features containing electroluminescent substances, the testing device comprising: two supports parallel to one another between which the document to be tested is placed, at least one of said supports being transparent; electrodes located at both said supports and producing an alternating electric field between each other similar to a plate condenser, said electric field penetrating the value/security instrument at least at the points where the EL-active security features are located, resulting in the EL-active security features being excited to the point of emitting photons that can be visually or mechanically evaluated. 21. The testing device according to claim 20, wherein both said electrodes are located opposite one another on said supports and the value/security instrument is p
