Common Control-Advanced

Click the first button in the right of the Scanner Control Box, and the box that appears in the right will be displayed.

Original
In the Original box are selections of the scan source. MiraScan supports three originals including Reflective (Flatbed), Transparent and Negative film. The ADF, Transparent and Negative film are available only if the needed adapters are installed in the scanner. If Negative film is selected, Line Art will be removed from the Image type box even if it is selected and reset the image type to be Color RGB.

Image Type
The Image Type box lists the following three image types. You can choose one of them as your setting.

Color (RGB)
Each pixel of a photo image occupies 24 bits (8 bits for Red, 8 bits for Green and 8 bits for Blue) or 48 bits(16 bits for Red, 16 bits for Green and 16 bits for Blue). It is the default setting.

Gray
Each pixel of a photo image occupies 8 bits. A total of 256 gray levels can be represented.

Line Art
Each pixel of a text image occupies 1 bit. A total of 2 gray levels, i.e., black and white, can be represented. Each bit is set to on or off depending on the threshold value. The threshold value can be set inside the Threshold dialog box. If this option is selected, all the following functions will be disabled ,e.g.High Quality 48 bits in Scan Mode, Filter and Color Wizard in the image Enhancement, Color Adjustment, B/C, Color Balance, Curve and Level in the image control tools bar, and Auto descreen in the Setting menu .

Scan Mode
There list two( For Line Art) or three ( for Color RGB and Gray )scan modes in the box .

High Speed
In High Speed scan mode,the scanner will scan an image faster but with lower quality than in the High Quality mode . It is the default setting for 300/600 dpi scanners.

High Quality
In High Quality scan mode,the scanner will scan an image slower but with higher quality than in the High Speed mode.
In addition,the scanning module will traverse only once in both of the scan modes.It is the default setting for 1200 dpi scanners.

High Quality 48 bits
Almost the same to High Quality with the exception that each pixel of an image occupies 48 bits. If Line Art is selected in Image Type, this option will be disabled.

Resolution

Resolution is the measure of pixel density in dots-per-inch (dpi) and lines-per-inch (lpi). Lpi is used to measure the resolution of halftones.A pixel is defined as the smallest distinct unit in an image. Each pixel contains a value usually described as the color. For example, each pixel in a black-and-white line drawing contains one of two values: black or white. However, in a color or grayscale original, such as a photograph, each pixel may represent one of many colors or shades of gray. Scanners are able to assign values to pixels based on hardware capabilities. A 4-Bit scanner can assign 4 bits of information to each pixel or up to 16 levels (shades of gray). Your 24-Bit scanner can assign 8 bits of information per pixel for grayscale originals of up to 256 shades of gray and 24 bits of information for color. The result is that more gray or color information is seen by the scanner during the scanning process and the resulting scanned reproduction is closer in quality to the original. It seems logical that you should scan each image at the highest resolution (dpi) available in order to create the best scanned image and obtain the best quality possible from your printer. If your original is line art, this is true. However, if you are scanning a grayscale or color original, high resolution has very little or no effect on the final printed image because of the limitations of the output devices currently on the market.
You can specify the resolution of the image to be scanned in the resolution box. The resolution unit is dpi (dots per inch). Click arrow button and select the needed resolution from the pop-up list. To customize the resolution of the image, select the Custom... item and the dialog box will pop up:

In this dialog box, you can adjust the resolution of the X (Horizontal) and Y (Vertical) axes independently by dragging the scroll bars, which may cause the difference of resolution at the X-axis from that at the Y-axis. Consequently, the scanned image will be out of the original shape . You can check the Sync box to adjust the resolutions at the X- and Y-axes simultaneously which can avoid the deformation. Press the OK button when you get the desired effect to confirm your settings ,or press the Cancel button to cancel your settings and close the dialog box..

Scaling

Scaling is a process that will allow you to enlarge or reduce different aspects of your scanned image. For example, you may have an 8'' x 10'' that you want to shrink down to 4'' x 5''. You can do that by scaling your image 50% or reducing its measurements by half. In another example, you may want to enlarge a 2” x 2” negative 200% to create an image that is twice the size of the original.

1. You can select a scaled percentage. You can do this by simply moving your cursor to the Scale % box and click to open the pop-up list , then select a desired percentage. 50%, for example, would shrink the image to 50% of its original size. 300% would enlarge it to three times its original size.

2. You can also customize the value. Select Custom to open the dialog in the right.In this dialog box, you can adjust the scales at the X (Horizontal) and Y (Vertical) axes independently by dragging the scroll bars, which may cause the difference of the scale at the X-axis from that at the Y-axis. Consequently, the scanned image will be out of the original shape . You can check the Sync box to adjust the resolutions at f the X- and Y-axes simultaneously which can avoid the deformation. Press the OK button when you get the desired effect to confirm your settings ,or press the Cancel button to cancel your settings and close the dialog box.

Tips:

1.The maximum and minimum scaling is determined by the resolution, and scaling above 100% will increase file size, while reducing it below 100% will dramatically reduce file size. This is an effective way to scan large images without tying up space or resources.

2. The maximum scaling depends on the scanner type, e.g. 3200% for 300/600 dpi scanners and 1600% for 1200 dpi scanners; and the minimum scaling MiraScan provides is 25%.
