UGRA Plate Control Wedge 1982
This fully featured control block has primarily been created for the control of offset platemaking. The presence of a 9 step halftone wedge also makes it highly suitable if the characteristic curves need to be determined during proofing and production printing.
The Ugra Plate Control Wedge 1982 consists of line film with a continuous tone film (grey wedge) mounted on it with double-sided adhesive tape.
It contains the following groups of panels
- Continuous tone wedge consisting of
13 panels that increase in density in
steps of 0.15. Used for the determination
of the gradation of an offset plate, as anadditional
control aid during negative
platemaking (hardening of the coating)
and, with suitable photo coatingl
developer combinations, for the control
of the developer Status.
- Microline panel for the visual control of
tonal value transfer in platemaking. It
contains lines and gaps varying in width
from 4 mm to 70 mm. The gradation of
the panel is fully compatible with the
FOGRA PMS system.
- Halftone wedge, consisting of 9 panels
increasing in steps of 10% and a solid
panel for the densitometric control of
tonal values or the dot gain during
printing. The screen ruling of these halftone
panels is 60/cm and the dots are
slightly elliptical.
- Slurring and doubling panels for the visual
and densitometric control of rolling
faults. A screen ruling of 48Icm is used at
angles of 0°, 90" and 45".
- Highlight and shadow panels for the visual
control of the areas of the lightest
of darkest tonal values on the plate.
The control block can be used for both positive and negative platemaking.
