Resolution - how many ppi?
Leuku's pictures are either scanned using high resolution
professional film scanners or they are digital files from professional
digital cameras.
The 300 ppi is something
of a myth. In most cases a resolution of 200 ppi is quite adequate. Somewhere
between 240 ppi and 300 ppi produces the highest possible quality in a
standard offset coated paper printing environment.
Should you require a Leuku image for purposes other
than the standard sizes available, then we can prepare the files for you
from the originals at the time of your order and arrange delivery.
Most of Leuku's images are already archived in 60MB
files for large image size requirements.
Interpolation
Our high quality pictures can easily be enlarged up
to 200% without any significant loss in quality.
These days print houses are moving to filmless plate
technology as well as changing from line screening to stocastic screening.
This basically means that picture quality suffers less from resizing that
it used to.
In this example a 16MB file is resized about 150% bigger
than the orginal dimensions by checking the Resample Image check box in
Photoshops Image Size dialogue box with Bicubic Smoother selected.
If you feel it necessary to sharpen the image it is
always best to this after the image has been sized to its final destination
dimensions.
For best results avoid resizing the images in layout
programs such as
InDesign and Quark Express.
