IRIScan
™
Desk 5 / Pro 5
Sunlight
When working with direct bright sunlight on your document,
be aware
•
that the shadow of the IRIScan
™
Desk may appear on your document before scanning. Once scanned,
the shadow is part of the original content. There is no way to hide it or to remove it. It may reduce OCR
quality.
TIP
: the rotate option can be used to move a shadow or the sunlight outside the scanner lens.
•
that some bright reflections can appear depending on the paper color or quality...
Glossy paper
Glossy paper
is NOT recommended as it gives lower quality results due to light reflections.
White Balance
The white color may appear bluish or yellowish if white is not the dominant color in your image (images with
large color blocks). When this happens, you can try to insert A4 white paper in the background of the document,
which helps to correct the color as much as possible.
White balance - bluish result for white color
White balance - correction of white color with added white in
background
Video recording
Zoom in or Zoom out is not registered if applied during video recording.
(Pro 5)
Only one type of Barcode can be recognized on the same page. A combination of the two types (bars and QR)
may give a partial result.
For optimal results of OCR, make sure you set the watermark outside the text (applicable to output formats PDF
searchable, PDF Txt, Word, Text, Excel).
Font size/Font
style
Font size under 8 and/or font style ‘light’ may give lower image quality and OCR accuracy.
