Need to laser print on the flesh side??

Recommended Posts

I have a large project where the customer wants to print some stuff on the flesh side of a  custom stamped coaster. Clearly stamping the back won't work as it will probably print through, a branding iron with custom stamp costs as much as some of the cheaper lasers. A rubber stamp would look crappy and silk screening would also look crappy.

I'm thinking this would do the job.

And suggestions or recommendations.  I have lost work because the customer wanted an inscription so this may find occasional use later. I will probably end up making +- 1000 of these. Will the laser hold up and what is a typical print time for a 2 x 1 print?

 

Thanks!

That looks pretty flimsy to me. Have you thought of farming the laser engraving out, like to a local makerspace?

Not enough margin to make it feasible, and it's a 1" x 2" text that just has to be legible, so not looking for the Mona Lisa. Just a quick and dirty imprint. All the hard work is on the grain side, custom stamp, etc. Used to worki in the wine industry in Santa Cruz and had many happy weekends in the Santa Rosa area checking out the competition. 

Engraver arriving tomorrow...

stohlman has at least one book on stamping the rough side. Check the free books on tandy e library.

The problem is that I am stamping the grain side and customer doesn't want anything else on the grain. I doubt that I can stamp the flesh side and not have a print through. I am stamping some samples now. I'll test it.

 

Thanks!

Not following, but I just tested stamping the flesh side and it will bleed through on the 5-6 oz leather the customer wants to use. 

I think the only option is the laser.

This suggests that you're hot stamping. It also suggests that the flesh side is fairly smooth. Have you considered foiling? Comes in gold silver blue pink etc etc. The point being the temperatures used for foiling are much lower and the contact is very brief compared to hot stamping

I use one of these lasers to engrave my makers mark, that being said I don’t know how many you will be able to do, also for my makers mark it takes about 30 min.

If using a low power, 3000Mw to 6000Mw Diode Laser it would be very slow and likely similar to Ray's situation. My 60W CO2 laser would probably take a few minutes

These are the first few prints off the new laser. I still need to fine tune the power which is now at 25%. The Made in AZ took 4 minutes, and it's the size the customer wants. The Celtic rondel is around 3" in diameter and took around 30 minutes on the grain side. It was just a test but I'd knock off a few percent on the power setting.

It was truly plug and play (Once you figure out how to convert the software from Chinese)  and has absolutely solved the problem for +- $150.

My workshop now smells like a dog crematorium, but the beauty of this engraver is that you can download the print to the unit, then disconnect from the PC and print anywhere there's an outlet. You could even place it in the middle of a hide. I intend to do my production work outside, and who knows, may keep the coyotes away (or attract them?!).

 

I may even incorporate the laser for adding a "custom made for Fred Jones" which I have had requests for in the past. Average print times around 5 minutes for text.

I decided to send the laser printer (attached) back to Amazon. I was not comfortable with the build quality as the scope of my project has increased and may require many hundreds of prints.

 

Does anyone have a recommendation for a plotter style engraver with larger than a 3x3" print area and at least 3W, preferably 5W. Would the extra 2W make a noticeable difference for engraving leather? I have been looking at this one as an option: It would be great to do multiple prints at the same time and have the print downloaded or on a thumb drive so I wouldn't have to be connected to the computer and could run this outside.

I have one of the lasers pictured and it works just fine.  I haven't used it 1000 times yet though.

I was quite happy with it for the original scope of the project, but as a former boss said (paraphrased) , only cheapskates can afford to buy things twice.

 

A bigger order means a bigger budget and a better laser engraver
