Retain Scan Module After Scan - Microtek ScanMaker 3600 User Manual

When the monitor gamma option is checked, click the up/down
arrow buttons to make the gray level of the boxes as close as
possible. Click OK to confirm.
Invert
This command creates a negative effect to an image. The Invert
effect is applied to all scan jobs, not just the selected scan job.
When an image is inverted, the brightness value of each pixel is
converted to the inverse value on the 256-step color values scale.
For example, a pixel in a positive image with a value of 255 is
changed to 0, and a pixel with a value of 5 is changed to 250.
Before After
To use this feature:
Choose the Invert command in the Preferences menu. A check (V)
appears next to the command when it is enabled.

Retain Scan Module after Scan

(for Macintosh only)
This command allows you to keep the ScanWizard 5 interface
running after scanning is completed and after the image has been
delivered to your image-editing software. This way, there is no need
to go back to the File-Acquire process to start ScanWizard 5 all over
again.
