Printing window stickers

[Riada]

Hi. I’m wondering if anyone knows how to print on adhesive side of vinyl for use as window stickers? We have an enquiry for double sided stickers 400mm diameter.
we have been asked a few times to price for this and I haven’t been able to find out how they’re printed. We are just about to install a Mimaki CJV330-160 next week.
we’re based in the UK BTW

Technically, you can't print on the adhesive side of the vinyl. Assuming that you don't have Latex/UV white ink capabilities, I'd suggest the following:

-Reverse print first image on clear vinyl
-Back first image with white vinyl (can be any cheap calendared cut vinyl, Avery 750, Oracal 651)
-Print second image on white vinyl with grey adhesive
-Laminate two parts together
-Cut to shape
-Ship to customer and collect the cheque

Ideally this works best when registration isn't super critical, but you can get it pretty damn close by ensuring you print a bounding box that will be exactly the same with both files/images.
Use that to register one to the other, with a lightbox or flashlight looking through the material.

Hope that all makes sense. Only have an ounce of coffee in the system and still waking up.
