           Color Conversion and K (Gray) Tables for Calamus SL

This archive contains the following files:

CLR_TABL.CDK - Reference version of the PC_168 color tables from the
               "Color Conversion" U2U TIP File
CLR_WSHT.CDK - A worksheet for creating and organizing color tables.
K_TABL  .CDK - All 256 possible K values with raster samples.
K_ALL256.CFT - A corrected 256 K .CFT for use with the above table.

K_ALL256.CFT should be copied to the COLOR subdirectory of your
Calamus SL folder, or wherever you normally keep your color lists.

This is the companion file to CLR_CONV.LZH, but neither is absolutely
necessary for the other to use.

Oh, NO! Not another gray scale chart!  I can hear it now :-)

Yes, folks I've decided to add to the confusion by tossing Yet Another
Grayscale (YAG) list into the ring.  Why, you ask?

A few of the previously uploaded files contained partial or
conflicting gray (K) lists.  I have also noticed that there has not
been a 'standard' for what values are assigned to the lists, i.e.,
some lists start counting at #0 for 0% K, while others start at #1 or
even #255.  I have no less than 12 "K" lists in my color folder,
including many that have errors.  Time to clean house and establish
some common ground.
  
This list was compliled to: a) assign standard numbers (names) to all
the possible values;  b) to align 50.2% (the closest SL gets to 50%)
with the actual 50.2% displayed raster pattern, and 3) for
testing with the upcoming Raster Generator U2U. 

Still trying to match that Calamus 1.09 "look" in your printouts? Use
the K table to test your Raster Generator settings.  Change the gray
columns' (they are individual raster frames grouped together)
line-screen values.  Hints: Try starting at around 18 LPCM and work
up. The middle grays work better at different LPCMs than the lighter
and darker values.  Have fun!

These lists, tables and worksheets were partially inspired by that much
delayed attempt at writing a RasGen tutorial.  'Cracking' the Raster
Generator's secrets has become an occupation in itself. :-)

Feedback on style and content is always welcome :-)
