From Version 6.4.2r4 onwards, SilverFast uses a completely new descreening in order to remove any screen dots from printed images. The newly developed descreening in SilverFast is able to detect the actual screen of the image automatically. 4 different descreening options are now available:

• Automatic descreening
• Automatic descreening (intensive)
• Descreening
• USM & Descreening

"Automatic descreening" and "Automatic descreening (intensive)" are fully automated and are available without any further dialogues.

Descreening is always confronted with the challenge to find out which is the proper screen. Whenever trying to descreen in Photoshop customers will most likely cruzify image details since the available filters and Photoshop's workflow are not designed specificly for a descreening process.

SilverFast's ingenious descreening uses a Fourier transformation to analyse the screen and also have the scanner select the best possible resolution for the required descreening process.

Descreening will generally decrease a little bit a sharpness. To compensate for the loss of sharpness SilverFast has an option to apply Unsharp Masking simultaneously.

Newspaper screen is 99 lpi / 38 lpcm
