title: pink tif file made from ImageMagick
body: <p>I am trying to send a tiff file through fax machine.</p>
  
  <p>This file seems fine with image viewer and paint, but</p>
  
  <p>my boss told me that while trying to send the tif file using fax program,</p>
  
  <p>he's getting pink all over his background instead of white..</p>
  
  <p>and 40 kb of tif file bumps up to 600kb while trying to send the tif file..</p>
  
  <p>And I used ImageMagick converting from PDF to Tiff, and the command line I used was</p>
  
  <p>"C:/Program Files/ImageMagick-7.0.3-Q16/convert.exe" -density 200 -resize 1728x2291 -monochrome -compress group4 D://fax_files/201612/20161208155410.pdf D://fax_files/201612/example/1.tif</p>
  
  <p><a href="https://i.stack.imgur.com/1xhrL.jpg" rel="nofollow noreferrer">the pink image</a> is here..</p>
  
  <p>Did I make any mistakes on using ImageMagick or are there any issues that cause the problem?</p>
  
  <p>If you know any, please help me out..</p>
  
  <p>Thank you in advance..</p>
