Chapter 2 Operating VRS Introduction This chapter explains how to operate VRS using the default settings, how to set up custom profiles, and how to use the VRS Adjustment Controls to configure and use the manual image enhancement features. This chapter also gives you information about advanced features and other options that are available from the VRS user interface. If you intend to use the Desktop Productivity features, refer to VRS Desktop Productivity Features on page 77.
Chapter 2 3 From the scanning application, select a VRS scan source.
Operating VRS Figure 2-3. Select Scanner Dialog Box (TWAIN-based application) 4 Click the OK or Scan button, as applicable to your scanning application. 5 For ImageControls-based applications, the VRS icon (Figure 2-4) will display in the Windows taskbar as soon as you select the scan source. For ISIS and TWAIN applications, the VRS icon will display when the scanner interface dialog box is displayed, or when you start scanning. Refer to Kofax VRS Scanning Interfaces on page 10 for more information.
Chapter 2 Kofax VRS Scanning Interfaces The scanning interface consists of basic scanner property settings, along with an option for accessing VRS. The scanning interface serves as a connection between VRS and your scanning application. Depending on the type of scanning application (ImageControls-based, ISIS-based, TWAIN-based), the options that appear on the VRS scanning interface will vary.
Operating VRS You can use the Kofax VRS ImageControls interface to control scanner functions. Under General, you can select from the following options: Source: Lists the available input paper source as Flatbed, ADF, Manual, or Panel. Depending upon the capabilities of the selected scanner, some sources may not be available. Destination: Lists the output tray (usually Bin 1 or Bin 2) for the pages to be scanned.
Chapter 2 X To scan using the Kofax VRS ImageControls interface 1 Open your scanning application. 2 Select a VRS scan source and click OK. The scan source is typically named as “ with SVRS,” where “” corresponds to the make and model of your scanner. Figure 2-6. Kofax VRS ImageControls Interface – Select Source 3 Select Source | Properties to open the Scanner Properties dialog box associated with the selected scan source. Figure 2-7.
Operating VRS Kofax VRS ISIS Interface The Kofax VRS ISIS interface serves as a connection between VRS and your ISIS scanning application. In most cases, the Kofax VRS ISIS interface will automatically display whenever you select the “Kofax VRS Scanner” source from your ISIS scanning application. Figure 2-8. Kofax VRS ISIS Interface Some ISIS applications hide the Kofax VRS ISIS interface and use their own interfaces instead.
Chapter 2 Under General, you can select the following options: Paper Source: Select from the available input paper sources: Flatbed or ADF. Dots Per Inch: Select an option for scan resolution or DPI. Mode: Select from the color modes supported by the scanner, which may include black and white, grayscale, or color. The mode selection also affects the availability of VRS features. Page Size: Select a paper size, such as Letter, Legal, A5, etc.
Operating VRS 5 Click OK to close the New Profile dialog box, or click Cancel to exit without making any changes. In the future, you can change a profile by selecting it, updating the settings under General, and then clicking Save. You may also load a profile by selecting it and clicking Restore from the Kofax VRS ISIS interface. Likewise, you remove a profile by selecting it and clicking Delete. 6 Start the scanning process.
Chapter 2 restored, or removed using the Save, Restore, or Delete buttons. You can establish multiple profiles to accommodate different scanning situations. Although you can create multiple profiles, only seven profiles at a time will be visible in the Profiles window on the Kofax VRS TWAIN interface. Note The profiles created from the Kofax VRS TWAIN interface differ from the profiles created in VRS. For details, refer to Working with Profiles on page 31.
Operating VRS Figure 2-12. Kofax VRS TWAIN Interface – Select Source 3 The Kofax VRS TWAIN interface will launch. From the General group, make your selections such as the Source, DPI, Color Mode, Paper Size, etc. 4 If desired, click Save to create a profile to save the updated settings. a At the Save Profile dialog box, type a name for the profile. b Click OK. In the future, you can load a profile by selecting it and clicking Restore from the Kofax VRS TWAIN interface.
Chapter 2 Configuring VRS Before You Scan The VRS default settings produce superior results for most document types, and in most cases, you can use VRS successfully without changing anything. VRS does give you the flexibility to configure operating preferences and adjust the default settings if necessary. This section explains some configuration options that are available to you: Using the VirtualReScan Administration Utility to customize the way that VRS responds to exception images.
Operating VRS Figure 2-13. VirtualReScan Administration Utility Dialog Box The default settings for VRS provide optimal scanning and accurate data capture for a wide range of documents. For most situations, it should not be necessary to adjust the default settings, which are listed in Table 2-1. Table 2-1.
Chapter 2 Table 2-1.
Operating VRS Figure 2-14. Warnings Tab Table 2-2 lists the types of warnings and their causes. Table 2-2. Warning Types Warning Cause Brightness Out of Range Brightness value for the image falls outside the acceptable range. Contrast Out of Range Contrast value for the image falls outside the acceptable range. Color Confidence Out of Range Color confidence value for the image is lower than the acceptable range.
Chapter 2 Brightness Out of Range Use the Brightness Out of Range threshold to define the valid range for brightness values. When a document is scanned, VRS evaluates the resulting image to determine its brightness. Then, VRS compares the actual brightness value to the user-defined acceptable range. The acceptable range is determined by starting with 50 and adding and subtracting the Brightness Out of Range threshold value listed on the Warnings tab.
Operating VRS VRS compares the percentage to the user-defined acceptable value, which is the Color Confidence Out of Range threshold setting on the Warnings tab. Based on this realtime evaluation, VRS either accepts the image and allows it to be passed on to the scanning application, or intercepts it and responds according to the Color Confidence Out of Range action in the Warnings tab.
Chapter 2 Table 2-4. Error Types (continued) Error Description Out of Paper No paper is available to scan. Cover Open Scanner cover is not closed securely. Scanner Offline1 The scanner is not ready to scan. Feeder Timeout1 The document feeder tries, but is unable to move the page for a period of time that exceeds the ADF timeout setting. Scanner Stop Key1 The user presses the “OI STOP” key on the scanner, causing an immediate transport stop, and pages are left somewhere in the transport.
Operating VRS Table 2-5. Action Types for Errors Action Type Description Interactive The VRS Interactive Viewer opens and displays the image in the VRS Interactive Viewer, so that you can apply new settings to the current image. Accelerated Scanning Tab When used with a scanning application that requests a bitonal image, VRS requests a grayscale image from the scanner. VRS analyzes the grayscale image and produces a clean, clear, bitonal image that is passed to the application.
Chapter 2 Figure 2-16. Accelerated Scanning Tab You can use the slider to select a scanning acceleration level from None to Maximum, while reducing the image quality from Best to Good. VRS performs the acceleration by scanning a grayscale image at a lower resolution then what was requested by the application. VRS performs its normal analysis on this image and produces a clean, clear, bitonal image.
Operating VRS Note When you select the first level of accelerated scanning, the image quality is virtually equivalent to non-accelerated scanning. However, higher levels of acceleration affect the image quality. Not all scanners increase in speed when you select accelerated scanning. If your scanner does not offer lower resolutions than the resolution selected in your scanning application, accelerated scanning will have no effect. Table 2-6.
Chapter 2 2 From the VRS taskbar menu, select Admin Utility. Figure 2-17. VirtualReScan Administration Utility 3 When the VirtualReScan Administration Utility displays, select and adjust the settings for the following tabs: 4 28 Warnings tab - Threshold. Type directly into the Threshold text box, or click the arrows to select a new threshold setting. For more information, refer to Warnings Tab on page 20. Warnings tab/Errors tab - Action.
Operating VRS Setting the VRS Operating Mode You can configure settings that control how often the VRS Interactive Viewer will be displayed during a scanning session. By selecting the QC Modes command from the VRS menu, you can set the VRS Interactive Viewer to open under different conditions. The default QC mode is “On Errors.” The default value for the Hardware Warnings setting is on (checked).
Chapter 2 available to Kofax Capture users, provided that the proper VRS Professional license is in place. For more information, refer to the Kofax Capture documentation. Disabled The VRS Interactive Viewer will not open, even if exception conditions occur. Hardware Warnings Use the Hardware Warnings option to specify how VRS should respond to hardware conditions such as Paper Jam, Out of Paper, and Cover Open.
Operating VRS Working with Profiles With VRS, you can scan documents and accurately capture data in the shortest time possible using the default settings, which have been carefully chosen to allow VRS to excel at a wide range of documents without adjustments. However, some document types may pose a challenge and they may require custom adjustments. If you expect to work with a high volume of problematic or challenging documents, the best solution may be to create a profile that contains custom settings.
Chapter 2 Creating a Profile You can create a profile by doing either of the following: Saving the current VRS Adjustment Controls settings under a new profile name Creating a profile from the Organize Profiles dialog box Before creating a profile, note the characters that are not acceptable for profile names, as shown in Table 2-7. Table 2-7.
Operating VRS 4 In the New Profile text box, assign a name to the new profile. Be sure to assign a profile name with alphanumeric characters and avoid the characters listed in Table 2-7. 5 Click OK to save the profile and close the New Profile dialog box. The new profile name will be added to the list of profiles, and it will also become the active profile. X To create a new profile from the Organize Profiles dialog box 1 Scan a sample image.
Chapter 2 a profile up or down with the Up and Down controls that are available in the Organize Profiles dialog box. The function keys for profiles are available only when the VRS Interactive Viewer is active. If the list of profiles exceeds the available viewing area in the Organize Profiles dialog box, you can use scroll bars to bring additional profiles into view.
Operating VRS X To change the active profile from the VRS taskbar menu 1 From the VRS taskbar menu, select the Profile command. 2 When the Profiles submenu opens, select the name of the profile you want to use. The profile selection stays in effect until you change it again. Updating a Profile If desired, you can update and save the settings associated with an existing profile. X To update a profile 1 From the VRS Interactive Viewer toolbar, select a profile name.
Chapter 2 2 From the profiles list, select the profile you want to remove. If desired, you can select multiple profiles for removal. 3 Click Delete. The profile name clears from the list. 4 If the deleted profile was the last profile in use, select another profile from the list and then click Load to make it active. 5 Click Close to exit the Organize Profiles dialog box.
Operating VRS 4 If necessary, use the VRS Adjustment Controls to adjust the image property settings to suit your preferences. For more information, refer to Using the VRS Adjustment Controls on page 48. 5 If you expect to use the updated settings on a regular basis, you can save them as a profile. Refer to Working with Profiles on page 31. 6 When you are satisfied with the preview image, select OK from the VRS Adjustment Controls.
Chapter 2 Using the VRS Interactive Viewer The VRS Interactive Viewer displays scanned images for your inspection and gives you access to the VRS Adjustment Controls, which can be used to apply changes to image properties (refer to Using the VRS Adjustment Controls on page 48). The purpose of the viewer is to show you what the image looks like when it scans, and to refresh the image as you apply changes.
Operating VRS Figure 2-25.
Chapter 2 Figure 2-26.
Operating VRS Scroll Bars If you resize the VRS Interactive Viewer so that the individual controls do not fit within the available space, horizontal and/or vertical scroll bars are displayed so that you can navigate to the controls that are not in view. Persistence The size and state of the VRS Interactive Viewer are maintained from one scanning session to another.

Chapter 2 Profile Menu You can use the Profile menu to create and manage VRS profiles. Each profile represents a saved combination of settings on the panels in the VRS Adjustment Controls. A profile works like a memorized strategy for image correction and enhancement. With the exception of the “Default settings” profile, which is predetermined and automatically included in your VRS installation, profiles are created by the user. VRS uses the “Default settings” profile unless you select another profile.
Operating VRS Enable Professional Features Demo This menu command is available only if a VRS “Basic” license is in effect. You can use this command to enable a demonstration of the VRS Professional features. While this mode is enabled, you have full access to the VRS Professional features and a “Kofax Demo Mode” stamp is applied to any images that you scan. For details, refer to Enabling the Professional Features Demo on page 69.
Chapter 2 Standard Toolbar The VRS Interactive Viewer toolbar gives you convenient shortcuts for selecting zoom options, advanced scanner properties, and profiles. Figure 2-28. VRS Interactive Viewer Standard Toolbar Zoom Tool Use the Zoom tool to select different image magnification options, which are also available from the Zoom menu (refer to Zoom Menu on page 43). Figure 2-29.
Operating VRS Profile Selection List Use the profile selection list on the toolbar to view or change the active profile selection. You can also select a profile from the Organize Profiles dialog box or the Profile submenu that is available from the VRS taskbar menu. For more information, refer to Working with Profiles on page 31. Figure 2-31.
Chapter 2 Using the VRS Adjustment Controls The VRS Adjustment Controls consist of six panels that give you options for adjusting image properties. The default settings are saved to a VRS profile called “Default settings.” Once you identify a set of adjustments that work well for a particular document type, you can save them in a custom profile that can be used in place of the default profile. For more information, refer to Working with Profiles on page 31. Figure 2-33.
Operating VRS Using the Clarity Panel This section gives you details about the Clarity panel, which gives you options to adjust the contrast, brightness, and gamma values for an image. In general, a high Contrast value enhances faint text and lines in your documents. Since brightness increases or decreases the overall density of your images, increasing the brightness level can clear up dark shaded documents. Gamma Correct is used to adjust images created with incorrect gamma encoding. Figure 2-34.
Chapter 2 Brightness and Contrast When the Auto Brightness check box is selected, VRS automatically assigns optimal values for brightness and displays those values in the manual Brightness slider and numeric text box. The Auto Brightness setting is not applicable when you scan in color mode. Moving the Brightness slider, entering a value in the Brightness numeric text box, or clicking in the Brightness-Contrast custom control turns off Auto Brightness. Figure 2-35.
Operating VRS Current brightness setting Acceptable range of brightness and contrast Current contrast setting Figure 2-36. Brightness-Contrast Custom Control The Brightness-Contrast custom control indicates the current value of the Brightness setting by means of a horizontal solid black line. The Brightness-Contrast custom control indicates the current value of the Contrast setting by means of a vertical solid black line.
Chapter 2 setting in black and white mode does not affect the value of the manual brightness setting in grayscale or color mode, because VRS keeps these values separate. Contrast Text Box When the VRS Interactive Viewer is launched, the Contrast numeric text box indicates the current value of the Contrast setting. The Contrast value of an image may be set manually using the Contrast numeric text box. The Contrast value may be set from 0 (very low contrast) to 100 (very high contrast).
Operating VRS If you have documents that are particularly challenging, you may achieve better results by applying a profile with the Advanced Clarity feature turned on. When Advanced Clarity is enabled, you can use the Intensity slider to control the degree of special processing that is applied. A setting of 1 requires less processing, while a setting of 5 corresponds to more aggressive processing (which may be required in special cases).
Chapter 2 5 From the Advanced Clarity group, select the Enable Advanced Clarity check box to turn on the feature that applies advanced processing to identify the optimal contrast and brightness settings for challenging documents. Note Advanced Clarity is available only for documents that are scanned in bitonal mode. It is also available for documents that are scanned in color mode and then output as bitonal using the Automatic Color Detection feature.
Operating VRS Using the Noise Panel You can use the filters on the Noise panel to enhance image quality and remove excessive speckling. Also, you can use the Fill Holes option to fill in hole marks with the background color of the surrounding area. As you adjust the Noise settings, the effects are applied to the image in the VRS Interactive Viewer window. You can fine-tune the settings until the image appearance meets your quality standards. Figure 2-38.
Chapter 2 Removing Noise from a Document Follow these general rules for removing noise from a document: If you have batches of mixed documents with varying quality, never use the Speckle Removal filter. You could risk losing information on documents. If the noise was produced by bleed-through of text from the back side or background patterns (such as the patterns commonly found on boarding passes), decrease the contrast from the Clarity panel.
Operating VRS Move the slider toward Large if removal of small, medium, and large dots will achieve the desired image quality. Moving the slider too far to the right may interfere with text recognition. 4 Select the Fill Holes check box to enable the feature that replaces hole marks (such as notebook paper hole marks) with the color of the area surrounding the holes. 5 Click OK.
Chapter 2 Figure 2-39. Skew Panel Deskew Option Use the Deskew option to automatically straighten any images that are skewed. You can achieve excellent results with black background or white background scanners.
Operating VRS Figure 2-40. Skew Panel - Deskew and Crop Options Auto Crop and Edge Cleanup Options Use the Auto Crop option to automatically crop every page to its original size. Auto Crop is important for a precise registration of each image in order to perform accurate optical character recognition (OCR). You can use Edge Cleanup to automatically remove black borders from an image. It is different from image cropping because it does not crop the image to its actual size.
Chapter 2 4 If automatic deskew is not selected, you can use the movable angle control arm to straighten an image by clicking anywhere on the grid. You can also adjust the skew as follows: a Position the mouse over the vertical arm, click, and hold. The cursor will change to a hand. b Drag the arm counter-clockwise to rotate the image to the left, or clockwise to rotate it to the right. You can rotate the image up to 360 degrees.
Operating VRS Using the Color Panel Use the Color panel to specify your preferences for Automatic Color Detection and related processing options. VRS uses the Automatic Color Detection process to determine if an image has any color content. If no color content is detected, then the document is processed as a bitonal image. When using Automatic Color Detection, it is important to test your settings on a sample document that is similar to the documents you expect to scan.
Chapter 2 Note The availability of the Color panel depends upon your VRS license and scanner, as well as the active scanning mode, which must be set to “Color.” X To configure the Color panel settings 1 From the VRS Adjustment Controls, select the Color panel. 2 Select the Enable Detection check box if you want to enable Automatic Color Detection.
Operating VRS 7 You can use the Output Format settings to override the results of Automatic Color Detection. These settings apply only to the current image in a batch. These settings are available only if Automatic Color Detection is enabled. You can select the following options: 8 Color: Image is processed in color, regardless of the results of the automatic color detection process.
Chapter 2 Figure 2-42. Background Panel X To configure the Background panel settings 1 From the VRS Adjustment Controls, select the Background panel. 2 Select the Enable Smoothing check box to turn on the background smoothing feature, which you can use to modify the background of a color image. If this check box is not selected, the background region of a color image is not altered when it is processed.
Operating VRS Black: All background color is changed to black. Automatic: All background pixels are smoothed to the same value, representing an average of the detected background colors. This selection is appropriate only when minor variations exist in the background color. Note If you select Automatic, the results may vary, according to the color detected in the background region of the scanned document.
Chapter 2 removal if blank page deletion is enabled. You can also configure VRS to detect small amounts of content, in which case the same speckled page may not be considered blank and it would not be deleted. When VRS evaluates the page content, the background color is ignored. Depending on the content sensitivity setting, VRS may fail to identify a blank page if it contains marks caused by holes (such as notebook paper holes) near the edge of the paper.
Operating VRS Figure 2-43. Blank Page Panel X To enable blank page detection 1 Scan a sample blank document that is similar to the documents that you plan to scan in a batch, and then select Preview from the VRS taskbar menu. 2 From the VRS Adjustment Controls, select the Blank Page panel. 3 Select the Enable Detection check box to turn on automatic blank page detection. Select the Delete Blank Pages check box to turn on automatic blank page deletion.
Chapter 2 Note When Blank Page Detection is enabled without deletion, the ability to notify the scanning application is supported only for ImageControls-based applications, rather than ISIS- or TWAIN-based applications. 4 Adjust the Content Sensitivity setting to determine how sensitive VRS is to page content. The possible values range from 1 to 100. A high sensitivity value means that VRS is very sensitive to small amounts of content, even if it is scattered on a page.
Operating VRS mode to First Page or Every Page, the scanning process stops to display the page that is appropriate for the active mode. If that page happens to be blank, it appears in the image viewing area with a message indicating that it has either been detected or marked for deletion (Figure 2-44). Blank pages may also display in the image viewing area when the QC mode is set to On Errors if an exception occurs in connection with the back side of the blank page.
Chapter 2 Once the VRS Professional Features Demonstration is enabled, the VRS Interactive Viewer will be refreshed and options on three additional panels will be available from the VRS Adjustment Controls: Color, Background, and Blank Page. Note To access the Color or Background panels while the Professional Features Demonstration mode is in effect, you must have color scanning selected from your scanning application.
Operating VRS any of these panels after exiting the Professional features demonstration, a message will display to remind you that full access requires a VRS Professional license. The message will include a link to the Upgrade VRS dialog box, which you can use to purchase a VRS Professional license. The options on the Clarity, Noise, and Skew panels will continue to be available. 3 When you resume scanning, the “Kofax Demo Mode” stamp will no longer be applied to your images.
Chapter 2 Note If the Scanner Driver Settings menu command or toolbar option is not available, your scanner driver does not support advanced features. 4 One of the following dialog boxes will display, according to the scanner that you have configured to work with VRS: Advanced Settings dialog box Advanced Properties dialog box Note For details about the Advanced Properties dialog box, refer to Advanced Properties on page 147.
Operating VRS VRS automatically will attempt to retry the scanning process, which will resume once you do something to resolve the exception condition. OK - Manual Mode: When the Auto Resolve Manager opens in manual mode (when the Action selection is Intervention), you need to resolve the equipment or paper transport issue.
