The odor is different. Not stronger, but different.
I print a lot of big runs so I have a vent system on my printer. If I had a smaller machine I wouldn't vent the stuff. The smell is minor.
I also vented OEM. No need to smell the inks if you don't have to.
It's BY FAR the best aftermarket ink I've ever used. I LOVE IT.
I used Triangle for years and had nothing but problems.
Triangle was more durable, but a PitA.
Solaris is trouble free, great color, low odor and less expensive than OEM.
Because of the lower odor the inks are more susceptible to abrasion damage, but I haven't had one complaint from a customer. Nor have I had one printer problem in ten months or continuous use. I have done usual consumable maintenance, (dampers, caps, as scheduled) but nothing major.
