Has anyone had any success using toner transfer methods in printing lettering onto front panels of project boxes.? I dont like the rub on transfer method and some easy diy budget idea would be good. ALSO What about colored laquered pc boards.? Has anyone successfuly been able to laquer up a board.? Regards gregW:-)

I used to do all my front panels with rub-on lettering. Looks fantastic, clear coat protects it, but what a pain to apply. A couple of times I used PCB material etched and backlit, also a pain as I was making photo etch patterns with rub-on patterns. Stefan, did you only use black toner transfer, or color laser? If there is a paper to use (or transparency film) for toner transfer, being able to use color laser would be pretty cool. Steve Greenfield

For a paper i used silicone coated paper, since i wanted a shiny black transfer. I covered the plate with clear tape to protect it better. ST

Hi, interested to know what kind of "photo-sensitising" you did on the aluminum. Is it a home-made type of photo-sensitiser or commercial type? Can you provide the formulation? TIA.

The instructions start with "This film is for colorizing black toner, printed from a laser or photocopier". It also says "Because "WhiteTRF" uses a very heavy pigment to be able to opaquely cover jet black toner, you will see large deposits of white where it shouldn't be. Don't panic. All excess white will easily lift off using adhesive tape. It is preferred to use a low tack tape like #M's Removable "MagicTape: or 3M '2070'. So the answer to your question seems to be yes. Check the Pulsar site <Pulsar.gs> for the specifics. Wayne

This was at least 25 years back, but I THINK I used the General Cement (?) firm's photosensitive spray.

Yes, I used the GreenTRF and it worked great, when I finally got a 'real' HP toner cartridge. I used Ferric Chloride and followed the instructions on the "15 Minute PCB" page. I etched two boards 1 was 2"x1 1/2" and the other was 2 1/2" x 1 3.4" and they both etched in a bit less then 1 minute each. I warmed the etchant in warm water as I was doing the etching outdoors and the temp was 34deg F. I haven't etched a board in over 20 years and did not believe it would be that fast. They both came out very good. I did not see any sigh if traces widening as others have seen. I will try to post some pictures tomorrow. The larger board did not come out so good with the WhiteTRF. I believe it was due to me not waiting long enough for the laminator to warm up. They say it should be warm enough in 12 minutes but the 'ready' light does not fully illuminate for 45 minutes in my workroom. I sent the first board through after about 15 minutes. The 2nd board went through about 50 minutes after turn on and, except for the blurring because I sent it through the printer twice, came out like I would expect. All in all for just starting to get the hang of this, I am very pleased. I have no idea what the WhiteTRF costs. It came with the starter kit along with a roll of tape to remove the excess white and a can of 'Goof Off' to remove the GreenTRF and Toner after etching. The WhiteTRF comes in a roll (like a bolt cloth would) 8 inches wide by 15 feet long, the same as the Green TRF. Wayne

The decal paper is available at model train suppliers. Runs a couple of dollars per sheet (8-1/2x11). Two types - laser and inkjet. The inkjet requires an overspray - krylon laquer, etc. for water resistance. You don't need to print a full sheet - print on plain paper, then cut and tape the decal paper over the printed area and re-print. Works great, no fuss, no chemicals, and can be slid around a bit while wet for exact positioning.

Toner transfers for front panels is the plan here too.:)
I did a bunch of experimenting on 1/8" aluminum. It doesn't transfer
exactly like the regular PCB stuff. I figured it was due to the
metal's ability to take in heat. The results were slightly
unpredictable here.
You'll be glad to know that I did find sort of a fix, by spraying a
light mist of clear acrylic (Krylon brand) over the metal beforehand.
It sort of "glued" the paper down to the sheet and helped grab the
toner. Not much heat or pressure was needed. I think I had crappy
results with a lacquer spray, so you may try different stuff. I'll
also be topcoating for protection.
Board labels have worked here too, but the varying surface on double
sided boards can screw things up pretty bad (there was a thread here a
little while ago).
If you didn't find out, the TRF rolls are only 6 or 7 dollars (usd)
through Digikey. I'm hoping the white will let me do white labels on
black panel. There's a decorative paper supplier on the web (www.
paperdirect.com), who has something similar. I think it sells in a
pack of sheets for $20. They've got weird colors like metallics and
stuff. They also do multi-color sample packs.
Take Care,
George
PS- Getting a bit wild one night, I tried toner to plastics and glass.
The glass split all to crap after it heated up, but a piece of
speckled, sand-colored formica took a good transfer. I really want to
do Lexan or Plexiglas. That was risky. The Lexan took a great transfer
on part of it, and got gooey with bubbles on the rest. It would
probably be a matter of getting the perfect heat/time down. I may try
it again with an acrylic coat and my new aluminum base plate on the
iron (could go a little better).2006-01-11 by PPC

I had some missing contact areas the first time I tried the Pulsar system. I was able to solve the problem by running the board through the laminator multiple times. I found it wasn't hot enough unless it was too hot to continue holding in my hand. The 9 inch laminator is slow to warm up. The "WARM" sign just starts to show up after about 15 minutes on my machine. Nevertheless, I get good contact after 15 minutes with six passes of the board. I really like the sponging style of board etch. I've produced 8 different boards averaging about 6 square inches each with a total of 4 ounces of etchant. There's no exhausted etchant to dispose of because I squeeze the used liquid out on a newspaper as its being used. I also like the fact that latex gloves, and a piece of sponge comprise the total of required equipment. It also works well at low temperatures. There is no need to heat the etchant.

Yes I uded Tinnit. > Did you place the whiteTRF > artwork (component legend) all in one sheet? or did you do the shapes > them individually? How do they look up close and personal? I cut pieces of the WhiteTRF sightly larger then the board. It was easy to position correctly over the copy on the paper. I did have to tape it across the top (with a piece of Avery label and at each corner on the last part through the printer) to keep the TRF from curling. That was another problem with the larger board, I didn't anchor the trailing edge corners. THe smaller board 'would' have been perfect 'up close and personal' if I hadn't run it through the printer twice. Even with the slight offset it is legible. I 'thought' the second pass through the printer was needid because the first board came out to light but I was wrong. The first board/s TRF curled and the temp was too low (I think) when I ran it through the laminator. BTW I have asked Pulsar to klet me know how much the 8 in. x 15 Ft bolt of WhiteTRF costs. I'll let you know when they answer. Regards Wayne
