print turning purple!!

I just refilled my cartridge because the printed pages were purplish in print. After I refilled it it was fine(full colors) for about a wk. Now it's printing purple again. My ink is about 1 1/2 yrs. old and is beginning to clot. Do you think that's why it is a purplish print again. Thank You!
