I am noticing some print surface irregularities in highlight values when I print 10x15 b/w images on 13x19 Ilford Gold Fiber Silk paper, which I did not notice with smaller image sizes.
The effect is one of dots or strings of dots that define light tonal areas rather than a continuous tone. I had done a nozzle check a few days ago and it seemed okay. I did it again with the same results but decided to do the head cleaning again anyway. I also replaced the LK and LLK cartridges that were very low on ink.
But alas none of these actions has solved the problem.
Any ideas or suggestions appreciated.
Thanks,
Roy
