Orajet 3651Intermediate Calendared - Ok W/Rapid Tac

[gemhdsigns]

Hi!
Question: Have a large 60” Diameter backlit install which we’re using Orajet 3651 (not 3651RA). It’s been a challenge eliminating bubbles on this large install - having to reprint.

Any issues / concerns with using Rapid Tac with this media?

I typically stick with dry installs but I feel like with this material, and this size print, it might be best to install wet.

Would welcome thoughts

Thank you!!

Use RapidTac lightly. Test it with a smaller piece on the surface you'll be applying to. If it gets too wet, it's best to make sure all bubbles are out and either let dry time or use a heat gun to speed the adhesion process. You using 210 or 290 as overlaminate?

Hi 3651 is not for backlights. But anyway, use wet method always u use acrylics

3651 has a tinted adhesive, so it is not the correct product for a backlit sign, but yes you can use rapid tac on it no issues.

Thank you.. Using 210 for laminate.

We’re using 3651 transparent gloss over white 7328 cast acrylic. Used this for smaller contour cut applications without issue. This project is a large sheet 60” diameter.

The problem using that way is that you cant put a lot of pigment on the substrate and i doubt colours are good (specially darker ones). Anyway, i would never put that over acrylic without water and a little soap

I worked with a company that printed a lot for backlit signage. Their shoe-in was 3651G Transparent with 210G overlaminate. This combo works great, but you have to "doublestrike" or lay a thick amount of ink down (so the reds don't look pink when the sign is lit, for example. Only problem, any time after 5 years, the overlaminate browns out and starts cracking. You will then have to use Oracal 3850 backlit printable to cover the brown burnt marks on the substrate.

Yep... I know 210 very good and their datasheet is just fake (like most orathings we have tried over 30 years). In Spain doesnt last more than 2 years before autodestroying. There are much better arlon laminates for a little more that dont get burn and never crack. But for backlights, nothing like a good backlight. And of course multilayering ink is compulsory
