Test form for digital pressure systems
This digital pressure test form in the format German Institute for Standardization A3 has originated from the experiences of the Fogra investigation 32.134 inquiries of the typographical qualities of digital pressure machines. She serves to form a visual and above all a measuring-technical judgment about the produced Digitaldruckqualität.
Components of the test form
(1) Ugra / Fogra digital pressure scale is personalised by the Fogra for the single buyer and is licensed. A detailed explanation of the fields occurs in the instructions belonging to the scale.
(2) Colour chart to the densitometrischen regulation of the pressure identity lines and to the colour-metrical regulation of the colour extent of digital printing. Check Constance of the colouring and the sound values of copy to copy.
(3) Full tone and grid fields to the check of the same moderation of the colouring and the sound values about the print format.
(4) Full tone beams in the primary colours to the regulation of colour density differences along and crosswise to the format.
(5) Course fields in the primary colours to the visual regulation of the sound value extent.
(6) Colour chart for a visual check of the visibility of sound value differences.
The colour chart exists of colour fields with sound values of 1% to 100% in sound value gradations of 1%. By the fields of every sound value line runs a grid beam whose sound value with a sound value from the middle of the line agrees. The first field is determined outgoing by the grid field with which the sound value of the field with the sound value of the grid beam agrees, on the left and on the right with which visually a difference was recognizable between the field and the beam.
(7) Lines and columns fields to the control of the resolution. The lines grid-shaped arranged in five-pfennig piece groups and columns are in the record in the strengths 0,011 mm (corresponds to a resolution of 2400 dpi), 0,021 mm (in 1200 dpi), 0,032 mm (800 dpi), 0,042 mm (600 dpi), 0,064 mm (400 dpi) and 0,085 mm (300 dpi) invested. In the circularly invested fields direction dependence can be recognised with the printing form exposure.
(8) Background surface, invested in a 70-percent Cyan-sound value, for the visual judgement of stripe education in the pressure.
(9) Line fields to the visual check of the Bildpassers.
(10) Line fields to the check of distance variations of the print format to the curve edges.
(11) Written field with positive and negative text lines in the type-sizes 10 points, 8 points and 6 points.
(12) Pictures from the ISO 12640 with sensitive compound colours or very fine detail drawing.
(13) More freely place for additional attaching of digital controlling stripes like Ugra / FOGRA digital pressure controlling stripe or the Ugra/Fogra-media wedge.
In the price Fogra digital pressure scale is included Ugra/. The test form is delivered in all current resolutions as EP on CD-ROM. As a bonus the edited version of the Fogra research report No. 32.134 inquiry of the typographical qualities is included beside the instructions also by digital pressure machines as a PDF!
Fogra-additional offer
As an other service we offer to evaluate provided digital pressure by these test forms. For such an evaluation are required per type of paper to 10 digital pressure of the test form.
The following points are checked: Resolution of the combination Belichtersystem/printing form, colour extent of the printings, sound value extent and pressure identity lines, same moderation of the colouring and the sound values about the format, same moderation of the colouring and the sound values more than 10 printings, being recognizable of sound value differences, Bildpasser and distance variations of the print format to the curve edges.
Should the ability for reproduction of the pressure system be checked, 3 other printings with which the record of the test form was loaded before the expression anew in the system are required.
