用VUESCAN做色彩管理吧

wally

<P>先用vuescan校正扫描仪，</P>
<P>再用扫描仪校正打印机，</P>
<P>效果很好。</P>

vuescan是什么东东啊.具体点.

wally

<P>我实在没有时间做教程，</P>
<P>我也是花了很多时间在多个软件间实验，</P>
<P>最后选择vuescsn，</P>
<P>理由是简单、易用，效果好，</P>
<P>只要你有扫描仪和it8，</P>
<P>就可以对扫描仪和打印机做icc，</P>
<P>vuescan是一专业扫描软件，</P>
<P>网上很好找。</P>

<H2>Scanner Profiling with IT8 Targets</H2>
<>Scanner profiling is the process of determining the precise color characteristics of a scanner or digital camera. VueScan uses IT8 targets (also called Q60 targets) to do this.
<>IT8 targets are included with many scanners. You can also obtain IT8 targets from several sources:
<><RE>  Kodak:       http://www.scarse.org/docs/kodak/Q60-order.pdf
  Wolf Faust:  http://www.targets.coloraid.de/
</PRE>To profile your scanner or digital camera with an IT8 target:
<><PRE> 1) Set "Input|Task" to "Profile scanner".
2) Copy the IT8 description file that came with your target into the
    Vuescan directory, and rename the copy "scanner.it8".
3) Press "Preview" button.
4) If necessary, rotate preview image so that the grey scale is at the
    bottom and the letters and numbers can be read normally.
5) Adjust size of the Vuescan cropping mask until it matches the IT8 target
    image. You may need to readjust the target on the scanner platten and
    press "Preview" again if the image is at an angle.
6) Choose "Profile|Profile scanner" from the drop-down menu.
7) The ICC profile will be written to "scanner.icc" in the
    VueScan directory.
</PRE>If you've previously made an ICC profile for your scanner, you only need to do the following:
<P><PRE> 1) Set "Color|Scanner color space" to "ICC profile"
2) Set "Color|Scanner ICC profile" to file name of ICC file
</PRE>VueScan normally reads and writes the ICC profile for the scanner using the file "scanner.icc". Alternatively, you can put the file name of the ICC profile into "Color|Scanner ICC profile".
<P>Every IT8 target has an associated data file that describes the exact color of each square in the target. You should either rename this file "scanner.it8" or put the file name into "Color|Scanner IT8 data".
<P>Note that the settings in the Color tab don't affect the profiling, but to see if the profiling works correctly, you probably want to set "Color|Color balance" to "Neutral".</P>

<H2>rinter Profiling with IT8 Targets</H2>
<>rinter profiling is the process of determining the precise color characteristics of a printer. This profile is unique to each type of paper in the printer and each change to the printer setup options.
<>To profile your printer with an IT8 target:
<><PRE> 1) Profile your scanner (see above)
2) Set "Input|Task" to "Make IT8 target"
3) Press "Scan" button
4) Insert printout into scanner
5) Set "Input|Task" to "Profile printer"
6) Press "Preview" button
7) If necessary, rotate preview image so that the grey scale is at the
    bottom and the letters and numbers can be read normally.
8) Adjust size of the Vuescan cropping mask until it matches the IT8 target
    image. You may need to readjust the target on the scanner platten and
    press "Preview" again if the image is at an angle.
9) Choose "Profile|Profile printer" from the drop-down menu
10) The ICC profile will be written to "printer.icc" in the VueScan directory.
</PRE>
<P>If you've previously made an ICC profile for a printer, you only need to do the following: </P>
<P><PRE> 1) Set "Color|Printer color space" to "ICC profile"
2) Set "Color|Printer ICC profile" to file name of ICC file
</PRE>
<P>VueScan normally reads and writes the ICC profile for a printer using the file "printer.icc". Alternatively, you can put the file name of the ICC profile into "Color|Printer ICC profile".</P>
<P>你花点时间研究一下吧，这两天太忙了。</P>

<>效果很好呀，</P>
<>我用profilemaker做过，700多K，</P>
<>vuescan生成的只有1K，</P>
<>但是profilemaker做的不能直接使用，</P>
<>需要进行微调，</P>
<P>而vuescan做的直接打印就行了。</P>

<>我也觉得奇怪，</P>
<>可效果确实不错呀，</P>
<>也许我自我感觉良好吧</P>

你把Vuescan做出来的ICC用记事本打开看看，就那么几行，如此简略，能准确才怪。</DIV>
<>这个问题是这样的，ICC有两种构成方式，一种称之为对应表的模式，比如PM所生成的ICC。这种结构的ICC简单的理解就好像是一个字典，每一个颜色都有一个转换后的颜色与之对应，色块越多，转换的结果越准确，但是文件的大小也会成倍的增大，转换的时间也会成倍的增加所以都是采用一种折中的方式既保证了一定的准确度，也保证了工作效率。另一种就是那种非常小的ICC了，他们被称为是矩阵结构。里面其实是一种转换公式，称之为转换矩阵，每遇到一种颜色都采用这个公式来进行转换，所以数据量非常小，因为只是保存了一种转换公式，并且转换的速度是非常快的。
<>这两种结构的ICC应该是各有优势，但是对于打印的ICC，还是以第一种居多一些。</P>
