Read me file about the Targets.

When these calibration targets were original designed and saved,there were several versions that support differnt levels of knowledge on what callibration targets shoud have, the standard of measurment to be used and the size of paper on which it is to be printed on. Note the date/times of each target to get what might be most useful.

There are several versions of the Target collection of calibration grids. One is named "Targets.pdf" and is designed to be printed on "letter" 8 1/2 x 11 inch paper. The other is "TargetA4.pdf" which is designed to be printed on european A4 size paper. TargetA4.pdf has not been tested due to a lack of A4 paper. If A4 size printouts are needed, verify that the metric sizes are correct using the metric ruler on each side of the calibration grid.
