Handles Varying Film Density
In Real-time Across The Film
It was therefore theorized that film density
could be adjusted by fine-tuning the concentrations of each PE.
It may, however, be possible to extract other parameters of interest, such as surface and film density
, as well as surface roughness from the same measurement.
The results demonstrate the progressive rise of the film density
along with the rise of silica concentration (Fig.
5 and 6 of un-annealed films reveal that the film density
levels off or decreases at/above 4 wt% and the third reveals the sharp annealing effect on a drawn film.
However, it has been difficult for barrier dielectrics to fulfill both the requirements of low k-value and perfect blocking properties because the latter property is usually diminished by reducing the k-value or essentially the film density
Current physical cavitation processes can reduce BOPP film density
An additional potential advantage of XRP is the ability to quantify not only the average film density
, but also the density profile normal to the film surface.
This densitometer transmits single wavelength light through X-ray film and indicates film density
within the range from 0.
If the Young's modulus and the film density
are known, the thickness of the film can be determined.
The Mammography Quality Standards Act requires that film density
values be reported in assessing phototimer performance.
Higher pigment loading was perhaps the biggest difference," said Harbin, who noted that printing with higher-strength inks yields good color at a lower film density
-- consuming about half the ink volume that would otherwise be required.
