As none of the transfer method never ever turned me on, I use presensitized board. Sure need couple of chemical and UV fluorescent, but works a treat, no chances to mess the alignment of any dual sided board, well for what I know of the other method

In our country the pre-sensitized ones are not sold, and lamination type film rolls, i saw with production houses, but outside it is a dream, as it is to be imported in bulk roll

As such we resort to TTS method and gives good results. The next board, i would take snaps and post them.
even if photographic process, i feel the best would be tracing paper as used by engineers of those days. with inkjet printer, it gives a dark enough pint.
