The main ingredients of a good Cad Plot are
1.  Use of proper pen assignments - in order to access the plot styles in autocad you must type in the command line
    ( stylesmanager ) , a window directly appears where your *.Ctb files are stored     Ctb files are pen assignments  
    wether it be named plot styles or default monocrhome, Some use color coding standard of .001 as red .002 as yellow
    .003 as green .004 as yellow .005 as blue .006 as magenta and so on.

2.  Please Check the Location of the project especially on the upper left corner of the drawing, Most of the time it is  
     often neglected and would result to a wastage of paper.

3. Adjust your perspective drawings to monochrome and do not use bmp extensions, we recommend to use jpeg or tif or
    png extension files.  sharpen up your image. If using photoshop adjust first using this  <image> adjustments>     
    Shadows & highlights > from there check "show more options " and adjust accordingly to your preferences
4. Never draw important data or elements  that need to be shown in the defpoints layer, any line or curve in this layer 
    could not be printed by the default printer.
5.  Always send us a font that you are using in your drawings
6.  Always include an image file for your perspective rendering. 
7.  Never use a .000 line, it never shows up in the blueprinting process, keep in mind a legible lineweight would be .0015
8.  Check your linescale by typing  <ltcale> or   < psltscale >
9.  When working in a model space check your proportion of your paper margins .  use the ratio and proportion formula
10.  Recommended screening for a plot style is 90%, 100% would result to ink blot and remember in sending pdf files , plot styles could no longer be changed. so change the screening before you publish it to pdf.
11.  When working in title blocks with xrefs , please make sure the file you sent us have the linked files as well .
