Digital BW, The Print

Hello guys

I am a periodic printer maybe once a month and I print in bulk so one short 30 to 40 13 by 19 or when a project is finished..

I was thinking could 1 R3000 share different ink sets. From what I understand is that flushing would need epson maintenace software and almost 15ml of ink. Assume I am ok with that...

would there be any adverse effect if I do the following:

I have 3 sets of Carts:

BW, Color , GLop(for storage)

Say

Next Month I need to print 30 color and 40 BW

Put in the color > Flush out glop> print color> Flush out color with Glop> Glop coat color prints> Flush out glop with BW > print BW > FLush with glop and store.

My worry is mainly would there be staining(seen this with 1400 but using clearbase) ? Reason being I use glop as a overcoat and possibly as a toner?

also is " Flush out color with Glop" redundant?

Since my BW inkset has 2 glop slots.

Thanks!
