1. STEP 3 Scanning Techniques Matching Scan Resolution to Purpose Plug in Module CS U provides many choices of resolution The resolution you choose should depend upon your output device the intended purpose of the image the type of image and your scanner It is generally recommended that you scan at a higher resolution than required for output This ensures that you obtain the best quality image which can then be reduced with an image editing program to suit specific purposes Different types of images require different scan settings However increases in scan resolution have a diminishing return after a certain point For example a text image can be scanned at 600 dpi for output to a 600 dpi laser printer while a color image should be scanned at 180 dpi to be output to a color bubble jet printer 360 dpi To output a color or grayscale image to a bubble jet printer use a resolution equal to half the resolution of the printer Set the resolution to 180 dpi for example for output on a 360 dpi printer e Scan in Black and White mode if you are scanning line art or other items that are Black and White with no shades of gray e Scan in Black and White mode if you are scanning a text image for conversion to editable text e Scan in 8bit Grayscale mode if you are scanning continuous tone Black and White photographs charcoal drawings or originals with shades of gray e Scan in 24bit Color mode if yo

Gamma value Plug in Module CS U and the screen display have different gamma values During a scanning job Plug in Module CS U receives the image read from the scanner as input and sends it to the parent application as output The gamma value in this interval where Plug in Module CS U converts input to output is the Plug in Module CS U gamma value On the other hand the data received from Plug in Module CS U as input is sent to the screen display as output The gamma value in this interval where the image input from Plug in Module CS U is converted to output for the screen display is the screen display gamma value Setting the screen display gamma value causes the scanner gamma value to be calibrated automatically as the inverse value For example if the screen display gamma value is set for 1 8 then the scanner gamma value is calibrated for 0 56 the inverse of 1 8 Hint e Please read the documents shipped with your display or contact the manufacturer s customer service department to obtain the correct gamma value for your particular display model e f you intend to adjust the color tone with ColorSync change the settings in the ColorSync control panel found within the Control Panels folder and do not manually change the gamma value settings as described in the following pages STEP 3 To Change the Gamma Value Settings b Click the gamma tab in the Tone Adjustment dialog P C
