Ugra/FOGRA Digital Plate Wedge
Digital Plattenbelichter, also known as a Computer-to-Plate-Systeme, need like all complicated systems suitable controlling means,
so that in the everyday production process the issue quality supervises
and thereby a secure production can be guaranteed.
After extensive test exposures and practise attempts originated a flat controlling stripe suited for practise. It is an advancement of the Ugra/FOGRAPostScript-controlling stripe, to the standard tools for PostScriptfähige issue devices which has lost as controlling means for Filmbelichter and for the digital working river nothing of his meaning.
Ugra / FOGRA digital record wedge orders more than a total of 6 functional groups or control panels:
Field of information
Resolution field
Geometrical diagnosis fields
Chess board fields
Visual authoritative steps (VRS)
Course wedge
A novelty are 11 visual authoritative steps. On this occasion, it concerns fields, from a chess board field and this
Chess board field pass surrounding authoritative field and of her
Surface cash ratio in 5-% steps of 35% to 85% reaches. Under
to theoretically ideal conditions and with linear Übertragungscharakteristik two fields should melt with 50% of surface cash ratio with each other, i.e. the brightness impression and the measurable sound value should prove in both areas in each case a surface cash ratio of 50%. Nevertheless, as a function of record type, Belichterkalibration, developer and Übertragungscharakteristik this becomes under
Practise terms hardly achieves, and movements upwards like down will seem. Importantly for the production everyday life are the respective VRS fields with which the optimum settings and issue results are reached. The visual control respective for the production process as optimum festgele te appearance of the VRS fields makes divergences visible. Other fields, contain
information oriented to resolution as well as a course wedge with which the sound value transference can be checked. Umherstellungsbedingte
To switch off heterogeneities in the record material, zero fields were laid between the semitone field rows in each case. With it the places lie side by side for the densitometrische measurement of the zero (carrier material free of layer) and the surface cash ratio.
The resolution field shows two semicircle fields,
their ray wreath in the first field from positive lines and in second from negative lines is generated. The lines have lines strengthens, of her
theoretical resolution of the issue device or the respective setting of the device corresponds.
The geometrical diagnosis fields contain lines which orientate themselves by the respective resolution settings of the Plattenbelichters.
Below the geometrical diagnosis fields there are the chess board fields. Accordingly of the respective inscriptions above the fields it concerns the square surfaces which show an easy, double and fourfold edge length.
