We are using Oce 550GT to do similar job. To get a good adhesion on such media, we need to use max power of UV lamp, then everything doing great.

We try on Oce 318GT, and 350GT,360GT, seems not as good as 550GT. By the way, we are using flexiable ink.

oce and fuji will work fine. Durst seems like overkill for just printing on aluminum.

you don't need a flatbed to print on aluminum. Ask me how I know :biggrin:

Yes, please explain how you've figured a way to by-pass digital vinyl and print directly to a piece of aluminum without any profiles for durability. :popcorn:

I seem to remember a few years ago someone mentioned putting .040 alum. in their r2r solvent and it worked...cant remember for the life of me who it was tho

Oh yes..... you can do it, but there won't be any reason to do it, as in almost all cases, the ink won't last printed directly onto aluminum, designated for digital media of some sort.

I can put pancake batter in a spray gun and spray it on a car and even clear coat it, but it won't last.

There's no need to print to something your printer isn't designed to do, unless you've made some major changes.... which no one mentioned yet.

I tryed printing 0.32 aluminum with my JV3 and it worked, the only thing is if your going to print large sheets I would build some type of tables to butt up against the printer so the material doesn't flap while going into the printer causing head strikes.

Sorry guys and girls, was gone for a while - the aluminum printing without a flat bed is quite simple - I do that all day long - on my Epson 9700 - there are s%^% load of ink receptive coatings, just rub it on the aluminum sheet, dry it w heat gun, stick it into the printer and print away. Make sure the printer is against the wall so you can lean the sheet - taking some weight off the printer. Then you can finish with automotive clear coat - I have powder coating shop next door, so I go that route - but automotive clear coat is as good. The whole concept of a flatbed printer is overrated imo - why can't you print on a media of choice and mount the thick substrate? That's not to say that I don't have one - I do, but I built one myself - just couldn't stomach shelling out that much $ for
couple of actuators. Going to print some tomorrow - will take a video for you to see.:toasting:

Interesting. I'd love to see a video of this!

I'm just curious as to what the advantage would be......? Sounds like a lot of work...pre-coating, printing, clearing, curing etc etc.

Would that process really produce a more durable product compared to printing on cast vinyl w/ cast laminate and mounting to aluminum?

Or are all those steps just to avoid the vinyl and laminate costs?
All the above - " to avoid the vinyl and laminate costs?" - but it's a collateral benefit - the visuals are unbelievable - after coating the image pops out off the surface, the sheen and all...You have to see it to appreciate. No way one can achieve same with vinyl or whatnot. The client is an artist/photographer, I do some 20 - 25 pieces a month for the guy and it gets only better. Here is the video:

It's a rather nice ending to a need out of necessity, but the OP's question was if you can print directly to aluminum with something other than a flatbed.

I think most took it to mean just that.... directly.

All the extra steps are manageable, but I personally, would not want to do that routinely. You'd never be capable of staying competitive with other flatbeds.

There's a guy named Alan that is on here and has converted a few R2R printers to flatbeds...He would be interested in seeing that Epson working for sure....

Yeah, it's brushed aluminum. I do print on stainless steel, copper, bronze - you name it - pushing the printer to limits - the worst thing is gonna happen the sheet will slide trough - never happened yet. I've printed sheets as large as 40x60. Sometimes I'll have to adjust the paper feed, nothing more...

hey guys... yup. printed exclusively flat .040 aluminum, and veneer on my flatbed jv3 for about eight years straight. you'll need to build two air (air hockey style) tables with some guides and feather boards. it works quite well for 4x6... a bit iffy past that. i've printed as big as 5x10, and 4x12 but would keep that to artistic purposes rather than signage.

all this was done with the jv3 (and a lot more)

i'm lucky to have an early CET 6x10 (16 head) flatbed now. getting used to the workflow and doing my mods to it currently.

here's what the rig looked like.

the secret is to have the material head very slightly down hill into the nip then exit very slightly uphill. this puts a mild reverse crown on the material. using this method, the sheet will be drawn through the printer (almost) without the pinch rollers down. straight through works, but not as well.

it's hilarious and just plain wrong what i did this poor house to get where i had to go. you can see the kitchen in the background. i now have a 33,000 square foot building and we've gone through about $400,000 and climbing setting it up (with all used equipment, save the limac cnc). funny thing is, in a few days i now, according to my eight year old divorce decree, have to put the house up for sale in two weeks. perfect timing if you ask me.
