Water Test Kit
The VEGRA-Test Kit has been developed with the aim to offer the printer a compact and reasonable product dealing with a complex of problems as there is
It offers him the preconditions for a printing process without any difficulties.
Even progressive printing machines contain only a part of the analysis equipment which is necessary for the evaluation of the fountain solution. Other important analytical results can be obtained quickly and without any problems with the help of the equipment included in the VEGRA-Test Kit.
Therefore, the VEGRA-Test Kit means a valuable aid for the printer to maintain the printing quality and to minimize the time of standstill of the machines resp the amount of waste copies.
Directions for use:
Examination of the quality and the quality steadiness of the water used for the printing process
Method of analysis: testing of total and carbonate hardness
Examination of the quality of the fountain soulution
Method of analysis: pH-measurement by a special indicator paper definition of the alcohol concentration (Vol %) by the areometer (see Methodes of Analysis n° 02.23)
Production of hand-mixed fountain solutions in order to
Equipment required from the VEGRA-Test Kit: measuring cup, measuring cylinder, 5 ml-plastic injection, areometer resp pH-value special indicator paper.
