Carl: Yes, their is a lot to learn. I am into CNC routed signs and have rotor engraver also, but this is not my main business. I sell and install millwork packages to GC's building apartments and condos. The signage we do is for those developments. The laser we purchased is a tie in to this. I have looked at the sublimation materials in Johnson Plastics catalog for quite a while, but I didn't unsderstand the OEM term as related to this. Now I see. Thank you for the information. I didn't mean to appear ignorant. Epilog EXT 40w, Vision 16x24,

Carl,

At what temp and time did you press that?

As I mentioned in another thread about OEM, I did not have good luck. What is the secret?

When I pressed my sample, a lot of the toner came off the wood, what stayed was mottled, and the finish on the wood actually bubbled in places ( I assume the temp was too high)......and it appeared as if what ever the coating is on the paper, came off and stayed on the wood.....

Thanks
Chuck

If it was not raw wood, the fact that the coating of the paper remained is a sign of too much time/temp/pressure. If the finish on the wood bubbled either the finish was never dried properly or again the time/temp/pressure was too much. I guess you can figure out which way my thinking is going. On raw wood that can happen, but on my few trials it does not happen on finished wood.

quote: At what temp and time did you press that? Which plaque are you working on? Oak finish? Or solid Alder? I agree with Harvey. If the backing is sticking to the plaque and pulling off the transfer sheet, you are: a) running too hot, or b) peeling hot or too warm. My first attempt at the Alder was 375F for 45 seconds. Plaque on bottom, then transfer, then 1/8" silicon pad, then teflon sheet. Peel cold. Not warm. The oak finish took about 4 tries to get the one in the image. Same setup as the Alder plaque, but 300F for 3 minutes. Again, that was the first one that worked, so there's probably some room for changes in the parameters. I also tried something different before peeling that will need further verification and possibly refinement. It may have no bearing on the success of the process. One thing you might want to verify is that the silicone pad is HOT before you start the press. I lower the platen on the silicone pad (no pressure) for several minutes.

Chuck,

Reduce your temp by 25-75 degrees. I have found that if your print has a lot of dark color I reduce the temp 25-75 degrees from what Mick suggests and increase the time by 1 1/2 min to 2 min more. It seems that the darker colors (more toner) flows better at lower temps and you don't get the mottled effect.

In general I like to add time and reduce the temperature.

Dye sub needs 400*, any change will result in color shift. Not so with CLTT. The color is fixed by the toner. The toner melts at about 160* so you do not need/want the surface temperature to get too high. Using the lower temperature and longer pressing time can help guarantee an even temperature across the product. It just feels 'righter' to me.
