Wrong size on PC Boards from Etcher's Paradise
« on: November 01, 2016, 01:43:35 PM »
Hello! I want to etch something from Etcher's Paradise, but the black/white pictures used for the toner transfer are much bigger than they're supposed to be. If I print it with 100% size it covers almost the whole A4 paper. How do I fix this? The images seem to be 300dpi and my printer is 600 dpi, if that makes any difference. Note that they're big before printing as well.

I'm guessing just scaling it will solve it, but which size (or percentage) should I scale it to?

If you open them in Adobe Acrobat Reader and print to 100% no scaling you should have no problems. What specific layout are you trying to print? I can test it for you.

I'm trying to print the Leviathan delay. (I built it on perfboard first but failed.)

There's a file in the ZIP called "Leviathan_PNP.psd". That's the one I've been trying to print (after exporting it using gimp.) The picture in the PDF-file looks like it's the right size so I tried using an online pdf image extractor to download the picture, but it was the same size as the psd-file.

Do you mean I should open the PDF-file in Adobe Acrobat Reader and then print the whole page?

Yes, I'd love if you'd test it for me!

Thanks!

Print the page from Acrobat, cut the PNP to size and tape it over the PCB image and print again to the same page.

Or if you can open the PSD file in Gimp, set the DPI of the image to 300.
I own madbeanpedals (duh). I am part owner of Function F(X).

That's the easy way is to print the whole PDF page that has the PNP on it.. or use GIMP like Brian suggests. I uses HP Presentation paper so printing a full page is not a big deal to me. But if your using blue or expensive paper then I can see this being a problem.

Sorry but I don't really understand the first part.

The DPI is already set to 300.

I'm using toner transfer paper, but it's not too expensive, so I guess it'll have to do until I find a better solution.

I don't really understand what Brian mean, so if any of you could explain I'd be really happy. As I said previously, the DPI of "Leviathan_PNP.psd" is already set to 300 in Gimp. Might be easier to use Photoshop, but I don't have it.

Thanks for the help!

Cut  a piece of your toner paper and tape it onto the pcb etch image which will be on your plain paper build document.  Put the whole page back through your printer and reprint.
Hope this helps.

Oh! Now I understand! That's a smart solution. Hopefully it doesn't get to thick for my printer to handle, though. I'll try it.

Thanks! :)
