We have been printing cardboard for some chapstick packaging for a while now with Metallic HSA and letting it air dry overnight. Obviously this isnt getting fully cured but we had some success during the summer months. Now the customer is coming back to us saying that the cardboard is sticking together and the image area is getting damaged when pulled apart. Do any of you know of a good air dry metallic ink that has a short dry time? We do about 6 different colored metallic so it would need to have some sort of mixing system. Thanks!

Back in the day when I printed flatstock as well as shirts, I mixed my own using the appropriate base with metal powders from Crescent.

we do have quite a bit of crecent powders in house. Will probably experiment today to try and match the look weve been getting with HSA. Any advice on what base to use for going onto non coated cardboard?

Nope, as I'm not really familiar with what's out there nowadays. (I assume something in the "poster ink" category) As Rusty suggested, Nazdar has always been good about matching inks and substrates.

alright, thanks for the help!

I have used nazdar 7200 for years. They have an overcoat clear and metallic pigments that work well. They offer a catalyst but I stopped using it a long time ago. We run everything under hair dryers for about 60 seconds with low/no heat. I use 195/225 for most prints. I have on occasion used a 160 but the dry time goes up drastically.

Could you not run these boxes through the dryer at a very low temp to help with drying?, I don't think a low temp little faster speed will hurt the boxes

I have run boxes through our Sprint 2000 dryer back in the day without problems, I think it would only go so low though - like 200F or something like that so there is a bottom limit if you have the heat on!
