Suggestions What printer and media to print these stickers?

You need something with a picoliter dot size smaller than 4pl to recreate text that small and have it legible. you may also want to run in unidirectional mode.

 

Epson Is the only brand I can think of between those brands.

Yes you will need to laminate for scratch resistance (if required), and for phones I would look at ij35 unless it needs to be removed.

 

I would sub to someone like Stouse which has all types of specialty applications.

 

S80 is probably the best option depending on the gamut needed and if you want a removable, look at the IJ40c or extreme removable IJ46.

 

i don't think any printer designed for signage would do a good job of this.
i would personally go see my friendly neighbourhood offset printer

 

I think the same thing. I would go with an offset printer and/or stouse.

 

Look at the Epsons S40, S60, and S80

 

When we have small label jobs that need high resolution we print them digitally.

Digital cut sheet vinyl isn’t cheap (costs us about $1.50 per 12x18 sheet with a min order of 600 sheets) but considering how quickly you can print on a production copier as opposed to a wf printer (esp running at a high pass count) the production cost is about the same.

Lindenmeyr carries cut sheet vinyl by Spinnaker (cheapest by far), Mohawk, and Neenah. OnlineLabels.com has some as well but only in 8.5x11 which makes cutting a royal pita if not impossible.

 

I would probably run these on a small format flatbed UV printer on vinyl with a clear on top - opposed to xerographic, as toner based vinyl stickers are pretty fragile in the long run and still need a laminate or clear coat for protection.

Scratch resistance and wear depends on the material used and would need to be tested.

To answer your question directly... Mimaki UJF 3042 or 6042 tick all the boxes.
I think sublimation may be well worth looking into for your task.
