Checks smoothness and gray balance with undithered scales of 256, 128, 64 & 32 steps
GrayRails.jpg (876 K - CMYK) (G)A great visual gray balance test. The same B&W image in CMYK, K-only and CMY only adjusted for G7 gray balance. Updated April 2004 from the older (flipped) version to eliminate scum dots in the K-only image.

Screen Test3.JPG (700 K - CMYK) Compare soft proofs to a master proof with
gray images in CMYK, K only & CMY only. Insert your own images but don't
lose the gray test! (Gray image derived with thanks from an image available from PIA/GATF.)
graycal_03.tif
(548 K - CMYK) A pretty standard target for finding the CMYK
values that match a specific gray balance. Somewhat obsoleted by the P2P target (above).

reversals, hue shifts etc. 24 radial HSB slices plus pastels, micro white & black & a continuous gray ramp.
MicroGrayTest.tif (64 K - RGB) Check any RGB system for neutrality with this 256-step gray target. Also test if you really have 24 bit video.
RGB_Curve_Guide.jpg (188 K - RGB) This chart helps new RGB to CMYK converts know which way to move their curves. Print and post it near your workstation.
HC2052F.zip (4.2 M - CMYK) A new CMYK characterization target designed to improve results in darker regions. May not work in some software. Updated to version "F" May 2011. New ReadMe Aug 2011.

and detect crossed curves introduced by calibration.
Proof
Qualifier RGB.tif (48 K - RGB) Check consistency of any RGB printing
system. Include alongside every RGB image and graph measurements on the PQM
