Re: Transparency film for laser printer
Once you degine the feed as transperency,the printer accordingly takes care of.

Re: Transparency film for laser printer
Nick, you've undoubtedly already considered using "Kinko's" to achieve the results you are looking for... ??
Not familiar with inkjet transparencies.? I've used high temperature LaserJet transparencies, but they all seem to shrink a little bit...? Have considered disabling the fuser to just get the powdered image on the substrate for easier transfer.? Then I laid down until the feeling went away...
on another unsolicited side-bar, I have a Brother printer and to achieve adequate toner density have to run an image through twice.? Several trials always necessary and don't expect to have good 20 mil registration.? Can be made to work but usually with considerable effort.
Final thought, in turns, ask each of your neighbors to print something out for you on a transparency...? Then work on making the winner your "Printer-buddy"...
Cheers...! (no not drinking, always like this...)

Jetstar makes both types of transparency, IIRC.

laser has a HOT ROLL heater around 180° to fix the toner on the paper

so if you use laser transparency on a inkjet printer, ink will not be fixed?
and if you use inkjet transparency paper on a laser printer, the risk if you

so take care

Re: Transparency film for laser printer

FWIW....
I've tried the laser transparencies.? The printer didn't lay down
enough toner at
it's heaviest setting, so I made two of them and carefully overlaid.?
That worked.

Re: Transparency film for laser printer
Hi Nick,
I have had much better luck with an inkjet printer and waterproof film used for screen printing than I ever had with a laser printer and transparencies. Very opaque, no pinholes, no need to double up. I find that the inkjet also has better dimensional accuracy. My laster tended to slightly change the scale of the image out to the edges. I do tell the printer to lay down maximum ink at maximum DPI. Other than that, nothing special.
Here are the films that I use, but I’m sure there are others that will work the same:
I don’t use any fancy ink. Just a cheap refill kit for HP cartridges.
Good luck,

Re: Photo Resist Preparation - thanks for the suggestions
Short wave sensitive.? Unshielded mercury vapor arcs.? Expose
through negatives where the trace is transparent, background is
opaque.? Develop in the appropriate developer and then put the dye
on.? That'll show you where the resist really is.? Cover holes (if
any) with something opaque, then etch.? It'll withstand ferric
chloride, although I'd recommend CuCl etchant (hydrochloric acid
and hydrogen peroxide to start with) because it's FAR cheaper,
better behaved, and works as well.
Once etched, strip off resist or solder through depending on
whether or not you want tin-lead plating.? I never had access to
tin lead plating when I was using KPR.
All of my boards then were using crepe paper tape, 2x photo
masters, an 8x10 view camera shooting on kodalith, (use kodalith
developer!? Dektol gives? you gray scale), and then contact
printing.

Re: USB scope pcb's. compare PCBCAD51 with Kicad
I am a little late to the party but have a look at this as it is the easiest PCB software I have ever used. Not free but very inexpensive:
I've made hundreds of layouts both hobby and professional with it. In a few hours with it you can make PCB layouts and components.
There is a free demo that does everything but save. Making 274-X gerbers and drill files are a breeze. You can also do toner transfer and CNC milled boards.
If it looks like something you would use join my SprintLayout group on groups.io. Definitely worth your time.
