I have run a few large Suede Tile jobs(using Onyx Postershop 12) and have had good success so far.
My question is, are there any tips to get consistent color throughout the entire job?
Light blues and grays are an issue sometimes.
Rotating tiles, thats a good thing.
Is your firmware at 7_00.11? That is supposed to help long run consistency.
Depending on how much ink (the light inks especially) your laying down, how many passes you're using and your color mode is CMYKcm you could be getting ink starvation in the one lc/lm printhead. Remedies are, slow the printer down by using a higher pass count or increase inter-swath delay, or use CMYK color mode if peppering from lack of lc/lm inks is not too objectionable.
