Using the HP Scanning software to affect image quality

The following topics are covered in this document. Use the links below to go to any topic section for detailed information.

Resizing scans using the resize tool

The resize tool allows the selection of the scanning area, and/or resizing the final scan. This is used for making small photographs into larger pictures. The example below shows a standard 35 mm slide resized to an 8 x 10 photograph.
Figure 2: Resize window
Click Basic on the menu bar, and then click Resize . This will expand the resize options on the right-hand side of the preview window.

Selecting the scanning area

The scanning area refers to the physical area on the glass that the scanner will actually scan. The maximum values are 8.50 inches for width (W), and 11.70 inches for height (H). The minimum value that can be assigned is 0.10 inches for both width and height. There are several different methods for adjusting the selection area dimensions.
The Units boxes display several different measurements for the image size. The available choices are listed:
  • inches
  • cm
  • points
  • pixels

Method 1

Manually enter the physical dimensions required.
  1. Click the value inside of the width (W) value box. Type a new value, and then press Enter .
  2. Click the value inside of the height (H) value box. Type in a new value, and then press Enter .

Method 2

A dotted line box with eight small black boxes on the corners, and on the sides surrounds the area that is currently selected. This box can be manually resized by clicking and holding one of the eight smaller boxes, and then dragging to the desired size.
Figure 3: Resizing arrow
  1. Move the mouse over one of the small black boxes. The mouse cursor will change to a two-way arrow. Click one of the four corner boxes to resize the width and height at the same time. Click a box that is not on a corner to adjust only the width or the height.
  2. Click and hold the mouse button and then drag the box to the desired size.
  3. Release the mouse button. The scan area will resize and then display the changes by resizing the dotted line box. All areas outside the selection area will be grayed-out.
  4. Repeat the process for the next black box until the desired area is selected.
    NOTE:Changing the selection area dimensions will automatically change the output dimensions unless the output dimensions are locked.

Workaround for 3670/3970 (only)

The workaround for the issue is to place a white sheet of paper on top of the image and scan or manually crop the image and accept for final scan.

Selecting the final scan size (output dimensions and scale)

Final scan size refers to the final size an image will appear. There are several different methods for adjusting the output size (reducing or enlarging the scanned image).

Method 1

Change the value inside of the Scale box. This will adjust the output dimensions proportionally to the values in the selection area.

Method 2

  1. Enter a value inside of the Output Dimensions width (W) and height (H) boxes.
  2. With the width value entered, press the Tab key. The height will automatically change to a proportional size of the selected area.
  3. Click the Lock button to lock the output size.

Method 3

Use the Scale box to resize the image by a percentage. Use a preset percentage or manually enter the desired percentage to resize the image. This will adjust the output dimensions proportionally.

Lightening/Darkening scans using the Lighten/Darken tool

The Lighten/Darken tool allows the adjustment of the highlights, midtones, shadows, and the white and black light levels in a scan.
Figure 4: Lighten/Darken window
Click Basic on the menu bar, and then click Lighten/Darken . This will expand the Lighten/Darken options on the right-hand side of the preview window.

Advanced and Auto buttons

Clicking the Advanced button expands the advanced menu, and allows adjusting the white and black light values . Pressing the Auto button sets all values to what the software determines to be best for the scanned image.

Highlights

The highlight is the value in the image that is represented on the screen as white. The range for the highlights field is 0 to 255. All values lighter than the highlight value set will appear as pure white.
The scanner has a default highlight setting of 204. Selecting a higher number makes more of the lighter values distinct, increasing details in light areas. Selecting a lower number makes fewer of the lighter values distinct, reducing details in the light areas.
The highlight tool changes slightly for different scan sources, such as an HP Scanjet Transparent Materials Adapter (TMA); however, the adjustment process remains the same for all sources. There are several different methods for adjusting the highlights value.

Method 1

Click and drag the highlight slider bar to the left to decrease the value or to the right to increase the value. The computer displays the changes to the image as the slider bar moves. There may be a slight delay for the screen to refresh.

Method 2

  1. Click the number inside of the highlight value box to highlight it.
  2. Type the desired value in the highlight value box, and then press Enter .

Clicking the Set Value button allows setting the highlights value equal to any place clicked inside the preview window.

Midtones

The midtone setting allows lightening or darkening the middle color values of a scanned image. The default midtone setting is 2.20 with a range between 1.0 and 4.0. Changing the value lower towards 1.0 darkens the image and changing the value higher towards 4.0 lightens the image.
Selecting a lower number makes more of the midrange color distinct and increases the amount of visible detail in midrange color areas.
Selecting a higher number makes the midrange color less distinct, reducing the amount of visible detail in the midrange color areas.
The midtones tool changes slightly for different scan sources, such as an HP Scanjet Transparent Materials Adapter (TMA); however, the adjustment process remains the same for all sources. There are several different methods for adjusting the midtones value.

Inverting colors in an image changes colors to an opposite value applying a reverse color effect. Black is changed to white, white to black, and colors to their complementary color (orange for blue, red for green). This tool is used for items such as negatives that will be printed in final photograph form. The default value for inverting colors on scans is off.

Turning inverted colors on and off

  1. Click Advanced on the menu bar, and then click Invert Colors . This will invert the colors in the image and change the Invert Colors icon to the on position .
  2. Click Advanced on the menu bar, and then click Invert Colors . This will return the colors in the image back to normal and change the Invert Colors icon to the off position .

Descreening a scan using the Descreen tool

Scanned pictures, photos, and images that look checked, blotchy, crosshatched, show a herringbone or checkerboard pattern, or have diagonal or horizontal stripes are displaying a type of interference known as moiré.
Pictures from magazines, newspapers or any other printed material are halftones (images that have been printed using a layering of black and colored dots to reproduce an image).
Scanning a halftone image repeats this layering process and due to different sampling rates and dots-per-inch between what the image is scanned at and what it is printed at, the moiré effect is sometimes seen. Descreening an image reduces or eliminates moire patterns in scanned images.
Use the descreen tool only when an undesirable pattern appears on an image scanned from a printed original.
NOTE:Scanning takes longer with descreen selected.

Turning descreen on and off

The default value for descreen is off.
  1. Click Advanced on the menu bar, and then click Descreen . The scanner will rescan the preview image and the final image with the Descreen tool turned on .
  2. Click Advanced on the menu bar, and then click Descreen . The scanner will rescan the preview image and the final image with the Descreen tool turned off .

Resetting options

Click Basic on the menu bar, and then click Reset Tools . This will reset all tools back to the default values.
