Try making bigger test strips. Ones that only show a particular area and not the range of tones with a larger test strip will not give you a good evaluation. try taking a 8x10 sheet of paper and cutting it into 4ths the ong way. 2x10 Put those at an angle across the scene you are printing. This will give you more of an indication of what is happening. better to burn a sheet of 8x10 than to waste printing 6 that won't be correct.
